SAUDI ARAMCO CONSTRUCTION SAFETY MANUAL

PREFACE Dhahran, Saudi Arabia

February, 1993

The purpose of the Saudi Aramco Construction Safety Manual (CSM) is to prevent injury, loss of life, and damage to assets. This is the fourth revision of the CSM. Since its 1974 introduction, the Construction Safety Manual has provided safety criteria for all construction work performed by Saudi Aramco and its contractors.

Many of the requirements in this manual detail the need for Saudi Aramco services or equipment. Where references indicate that certain equipment (fall protection, safety shoes, etc.) should be provided or services rendered (bio-monitoring, etc.), the intent is that contractors must provide equivalent equipment or services (as approved by Saudi Aramco) from their own resources.

The construction industry functions in a dynamically changing work environment in which updating of equipment and standards is a continuous process resulting from changes in operating variables, regulatory requirements, and safety practices. Although this manual has been updated to reflect the latest Saudi Aramco and construction industry practices, as time goes on there may be a need to consider new procedures, standards, or operating conditions. Such new developments, including potential conflicts with existing provisions, should be referred to the Loss Prevention Department for resolution. The Loss Prevention Department will issue interim revisions or updates where appropriate.

Good loss prevention is an integral part of good project management. For our projects and maintenance programs to proceed safely, all Saudi Aramco and contractor personnel involved in construction activities, whether management or line employees, need to understand and follow the provisions in this Manual. Only with the active commitment of everyone can we ensure that Saudi Aramco maintains the safest possible work environment.

February 1993 - Construction Safety Manual: Saudi Aramco Loss Prevention Policy And Program Page 31

1.0 SAUDI ARAMCO LOSS PREVENTION POLICY AND

PROGRAM

Saudi Aramco is committed to prevention of accidents to minimize loss of life or bodily injury to its employees and damage to its physical assets.

In fulfilling this commitment, which is as essential and equally important as production objectives, Saudi Aramco will provide and maintain a safe and healthful work environment and protect the public against foreseeable hazards resulting from operations.

Loss in production and property resulting from accidental occurrences can be minimized through good management. Loss prevention is one aspect of this loss control philosophy and is the direct responsibility of line management.

All management functions, including business line and associated management, will comply with Saudi Arab Government and Company loss prevention requirements applicable to the design, operation, maintenance and construction of facilities and/or equipment. When conformity with any of these requirements is not practicable or cost effective, an amendment to such a requirement will be considered. Reviews for compliance with this policy will be performed on a selective basis.

1.1 Loss Prevention Policy Implementation

1.1.1 Compliance With Construction Requirements

The application of the best petroleum industry loss control practices minimizes risk to personnel and property. The design, construction, modification, operation and maintenance of facilities and equipment and construction as practiced by Saudi Aramco and/or contractors, will meet Saudi Arab Government and Saudi Aramco safety requirements as covered in this manual and in relevant General Instructions, including the Company's Engineering Standards. When conformity with any of these requirements is impractical or not cost effective, a waiver will be sought from the Chief Engineer.

1.1.2 Operating Standards and Instructions

Risks that cannot be eliminated through design are controlled by operating standards and instructions. Compliance with safety standards and instructions will be consistently enforced for both Saudi Aramco operations personnel and contractors alike.

1.1.3 Personal Protection

Personal protective equipment, periodic environmental monitoring and bio-surveillance will be used to help to protect all employees against exposure to safety and health hazards (e.g., radiation, H2S, etc.) which cannot be eliminated.

1.1.4 Inspection

Inspections to detect and correct unsafe practices and conditions will be conducted periodically by Saudi Aramco and/or contractor.

February 1993 - 1.0 Saudi Aramco Loss Prevention Policy And Program Page 32

1.1.5 Education and Training

All employees shall be provided with ongoing safety education and training as well as helping to develop those skills that are required to perform, supervise and manage assigned tasks without mishap.

1.1.6 Motivation and Recognition

Good communications, a viable suggestion system and the recognition of good safety performance, encourages employee participation in loss prevention programs.

1.1.7 Job Placement

Employees must only be assigned tasks that are consistent with their physical capacities and job skills; this enable employees to work without endangering themselves or others.

1.1.8 Response to Accidental Occurrences

Site specific effective emergency response plans must be established as per the guidelines of Appendix B.2 of this manual. These should include measures to contain or control an emergency or disaster when an accident occurs to minimize the loss of resources, a reporting and investigation system to determine the cause of the accident, and the adoption of corrective actions to avoid a recurrence.

1.1.9 Contractor Safety

Saudi Aramco proponent departments will monitor all construction activity to ensure that services are performed in conformity with Saudi Aramco loss prevention policies, principles and practices and do not imperil any person or property. Proponents will register each contractor employing 50 or more persons in the Saudi Aramco Contractor Safety Competition. (See Appendix A - Figures A.1, A.2 and A.3.)

1.1.10 Off-The-Job Safety

Off-the-job safety training (e.g. seat belt use) shall be vigorously practiced to provide the means for all employees to protect themselves and their families from harm during off-duty hours.

1.1.11 Traffic Safety

Operators of Company vehicles must receive defensive driving training and driver evaluations and be in possession of a current Saudi Arab government driver's license. A vehicle operator will be held accountable for the vehicle assigned to him and he must ensure that it is always operated in a safe and lawful manner.


1.1.12 Accountability

All employees shall be held accountable for personal and functional safety performance. An important factor in an employee's overall job performance evaluation will be how well the employee meets his safety responsibilities.

1.1.13 Compliance Reviews

On a selective basis, compliance reviews will be conducted by teams that include people with related expertise to determine compliance with this policy. In order to ensure the credibility and effectiveness of the review, the team members must be detached from the operation being reviewed.

1.2 Saudi Aramco Loss Prevention Requirements For Contractors

Saudi Aramco Loss Prevention requirements for contractors are contained in Schedule 'D' of contracts (See Appendix A - Figure A.4). The safe practices specified in Schedule 'D' shall be followed by all contractors during the performance of all work under each contract with Saudi Aramco.

The requirements in Schedule 'D' are the minimum acceptable to Saudi Aramco. Any deviation from the requirements of Schedule 'D' must be signed in writing by the Company representative. The contractor shall also take any additional measures which the Company representative may determine to be reasonable and necessary to protect against the injury (or death) of any person, or damage (or loss) of any property during the contractor's performance of the work under the contract.

1.2.1 Non-Compliance

The Company representative will notify the contractor, in writing, of any violation of the requirements of Schedule 'D' and provide corrective action to rectify the situation. After receipt of such notice, the contractor shall immediately take corrective action. Such notices when delivered to the contractor's representative at the site of the work shall be deemed sufficient notice to the contractor under Schedule 'D'. If the contractor fails to take corrective action promptly, the company representative may issue an order stopping all or part of the work until satisfactory corrective action has been taken. The contractor will not be eligible to use any part of the lost time incurred as a result of such stop orders as the subject of a claim for extension of time, additional costs or damages. Compliance with the provisions of Schedule 'D' by subcontractors shall be the responsibility of the contractor.

1.2.2 Assistance

The contractor may request advice on establishing feasible and effective safety practices for the job. The company representative will assist the contractor's representative by providing guidance on good safety practices, pointing out unsafe conditions, and applying his experience and judgment in helping to improve the contractor's overall job safety.


1.2.3 Standards and Instructions

All work and equipment must conform to Saudi Aramco Standards and General Instructions. Where no standard or instruction is available to cover a particular item, the contractor shall request that Saudi Aramco specify the standard of work or equipment required. The term, "Approved Standards" in Schedule 'D' refers to standards which are approved by Saudi Aramco.

1.3 Contractor's Loss Prevention Program

The contractor shall develop and implement a loss prevention program that will conform with Saudi Aramco loss prevention policies and procedures.

1.3.1 Written Program

Prior to the commencement of contractual activity, the contractor shall submit a written job-specific loss prevention program to the Saudi Aramco company representative. The latter is required to forward a copy of the program to the Loss Prevention Department. The Contractor's written loss prevention program shall address the following:

February 1993 - Construction Safety Manual: Accident Investigation, Analysis And Reporting Page 39

3.0 ACCIDENT INVESTIGATION, ANALYSIS AND

REPORTING

Much is learned through experience. A thorough investigation and analysis of an accident can help to prevent future accidents. To learn by experience, however, means that a system for the retrieval of information must be set up and statistical records must be kept of injury, death and property damage. With such a system operational, information can be collated and analyzed to show accident patterns. The contractor can then emphasize those areas in which safety education and training is needed most.

The contractor is responsible for reporting accidents to Saudi Aramco and in some cases to the Saudi Arab Government as required. This section covers these reporting requirements and the principles behind accident investigation and analysis.

INSTRUCTIONS AND STANDARDS

Saudi Aramco General Instructions:

GI 6.001 Notification Requirements for Incidents (Including Fires)

GI 6.003 Guide for Committees Investigating Major Incidents or Engineering Reviews of Other Incidents

GI 6.029 Reporting and Recording Of Motor Vehicle Accidents

GI 7.026 Lifting/Elevating and Mobile Equipment Accident Reporting Procedures

3.1 Reports Required by Saudi Aramco

Reports are required by Saudi Aramco as per Schedule 'D' of the contract.

Contractor shall ensure that an immediate report is made to the Company Representative in the case of all:

• Fatal injuries • Injuries requiring medical attention which result in lost time • Damage over SR 10,000 to contractor's plant or equipment • Damage, in any amount, to Saudi Aramco's equipment or property • Fires • Damage and near misses to cranes and heavy equipment (GI 7.026)

For accidents involving Contractor employee fatalities, serious injury to two or more Contractor employees, or damage to Saudi Aramco equipment or property, a preliminary written report shall be submitted within 24 hours followed by a detailed written report submitted within three days to the Company Representative. In addition, Saudi Aramco may convene an engineering review or investigation committee in accordance with the requirements of GI 6.001 and GI 6.003 (see Figure I.1).

February 1993 - 3.0 Accident Investigation, Analysis And Reporting Page 40

Contractor shall maintain, in a format approved by the Company Representative, a current record showing all:

• Work injuries • Fires • Incidents of property damage over SR 10,000 • Motor vehicle accident • Incidents involving damage to Saudi Aramco equipment and property • Damage and near misses to cranes and heavy equipment (GI 7.026)

The record shall be available for inspection at all times and shall be submitted to Saudi Aramco on request. (See Figure I.2.)

A final written report shall be prepared and submitted to the Company as per the provisions of GI 6.003. In the case of serious accidents, however, a detailed account of the circumstances, witnesses' statements and descriptive photographs are required.

In addition to the reports required above, the contractor must keep a record of all injuries and damages on a form approved by the Company (Figure I.2). A copy of this record shall be sent to the proponent department and to the contractor's project management. Monthly summary reports are required in addition to the individual reports.

3.2 Accident Investigation

The point of an accident investigation is to prevent recurrence of similar accidents; to determine facts rather than to find faults.

The main reasons for conducting an accident investigation are:

1. To find the causes so that similar accidents may be prevented; 2. To determine the point at which "unplanned" events took over from the "planned"

sequence of events; 3. To recommend what corrective action should be taken.

3.2.1 Responsibilities for Investigation

3.2.1.1 Supervisor/Safety Representative

The supervisor and/or safety representative shall carry out an immediate investigation of any accident which occurs within his area of responsibility. The preliminary accident report must be completed and submitted within 24 hours to the Saudi Aramco Company representative with a copy to the Loss Prevention Department. A final report on the incident shall be submitted within three days detailing any additional information and corrective action needed.

3.2.1.2 Project Manager

The project manager shall review all accident reports to ensure that all the necessary corrective action has been taken and that he has addressed any items that may require action on his part.


3.3 Cases to be Investigated

Incidents that result in property damage or serious injuries to personnel and hospitalization of two or more employees must be fully investigated and reported. Unless the real cause is known, the hazard cannot be controlled in the future. The near-miss incident is equally important from the point of view of prevention and should also be thoroughly investigated.

3.4 Accident Investigation Guidelines

The scene of an accident must be left undisturbed until Government Affairs, Industrial Security, the Loss Prevention Department and the safety supervisor have conducted their investigation. In some cases the accident site must be rendered safe so as not to contribute to further accidents. However precautions shall be taken to keep the accident scene intact as much as is possible, to assist local police in their investigation. The investigation should include, but not be limited to the following:

1. Questioning the man in charge and finding out what was planned. 2. Finding out the injured man's job or the normal configuration and function of the

damaged equipment or plant. 3. Questioning the injured man as soon as possible. 4. Questioning the witnesses separately as to what they actually saw, not what they think

happened. 5. Studying the equipment or plant layout and noting any signs of misuse. 6. Finding the explanation of any irregularities. 7. From the information obtained, establishing the reason why the "unplanned" events

took over from those that were "planned". 8. Recommending items of corrective action and methods of implementing them to prevent

the recurrence of the incident. 9. Making a scaled drawing of the accident scene and supplement that with supporting

photographs.

3.5 Accident Analysis

3.5.1 Classification

Contractors can use nine main classifications to analyze industrial accidents. Every contractor should go through the following classifications and their breakdowns to determine which of these (if any) apply to the incidents in which they were involved. These records help to illustrate accident trends. In turn, this helps the Loss Prevention Department (Saudi Aramco) evaluate their safety program and modify or upgrade it as needed. This information is supplemental to the findings and reporting requirements of the preceding "Accident Investigation" sections.


The nine classifications with their individual breakdowns are:

1. Falls (Of Persons from Heights) 5. Equipment To the ground or another level Moving Parts From scaffolding Equipment in motion From ladders Hot surfaces Into holes, trenches, etc. Into water 1a. Falls (Of Persons on the Level) 6. Hand Tools To the ground Cartridge hammers Against objects Power tools Non-power tools 2. Handling Objects 7. Transportation From lifting Road From pulling or pushing Site Handling materials Electric shock 3. Striking Against Objects 8. Lifting Appliances Protruding nails Cranes Scaffold tubes and fittings Hoists and winches Stepping or kneeling on objects Pull-lifts, pulleys, wheels, etc. Piling frames A-frames Excavations 4. Struck by Objects 9. Hazardous Atmospheres Falling objects Hydrogen Sulfide Foreign bodies in eyes Others Flying objects

February 1993 - Construction Safety - Emergency Procedures Page 49

5.0 EMERGENCY PROCEDURES

Saudi Aramco departments and organizations have established disaster and emergency response plans that are documented in general instructions (GIs), department operating instruction manuals (OIMs), terminal instruction manuals (TIMs), and refinery instruction manuals (RIMs), etc. All managers and supervisors are exp ected to become familiar with the emergency procedures of the plants and areas in which any of their staff are working. Construction site-specific written emergency procedures shall be prepared by the Contractor and submitted as part of the Contractor's loss prevention program plan. Details of the written procedures may be obtained from the Saudi Aramco representative, operating supervisor, or loss prevention engineer.

General guidelines for preparing emergency response plans can be found in the following Saudi Aramco Loss Prevention Department publication:

Guidelines For Preparing Emergency Response Plans, October 1989

5.1 Action to be Taken

In an emergency, or on hearing the "Stop Work Alarm", every supervisor shall ensure the following:

1. All work is stopped at once. 2. All equipment is shut down. 3. All men are evacuated to a pre-determined assembly point. 4. A roll call is taken and every man is accounted for. 5. No one is permitted to return to work until notification has been received from

operations or from the company representative that it is safe to do so.

Refer to the specific procedures established in each Company operating area.

5.2 Contact After Office Hours

The contractor's supervisor shall give his home address and telephone number (and that of his replacement) to the company representative so that he may be contacted after hours in case of emergency involving the contractor's job or equipment. These telephone numbers are to be kept current and posted at the job-site.

5.3 Help in an Emergency

5.3.1

In the event of an emergency situation (serious personal injury, fire, critical damage to operating equipment, etc.) help may be obtained by contacting the nearest Saudi Aramco Main Gate or Security Control Center. This may be done:

1. By telephone: Dial the emergency telephone number 110. 2. By radio: Radio an operations group that has a telephone in the Saudi

Aramco system and ask them to dial 110 when the Main Gate or Security Control Center cannot be contacted directly.

February 1993 - 5.0 Emergency Procedures Page 50

3. By messenger: Send a messenger to the nearest telephone, radio, or Saudi Aramco Main Gate or Security Control Center.

5.3.2

When transmitting a message by telephone, radio, or messenger, ensure that you clearly identify yourself by giving:

• Your exact location • Nature of emergency • Service required and repeat the message • Your name • Your badge number

Stay on the telephone until you are told to hang up. If possible, post a lookout to direct the ambulance, fire truck or helicopter to the right location.

February 1993 - Construction Safety Manual - Safety Training Page 51

6.0 SAFETY TRAINING

Good safety training is important to employees who are learning a new trade but it is also necessary to keep supervisors and skilled operators up-to-date with current safety technology and practices. Safe working practices are learned when employees understand how an accident was caused. Measures can then be taken to prevent a recurrence. People who are trained to do their jobs correctly can also be expected to do them safely.


Schedule 'D':

Saudi Aramco Safety, Health and Environmental Requirements - Loss Prevention Program

6.1 Safety Training for Supervisors

6.1.1

The immediate job of preventing accidents falls upon the supervisor not because it has been arbitrarily assigned to him, but because accident prevention and production control are closely associated supervisory functions.

The most direct way to develop the desired attitudes and to impart the necessary information about safety to supervisors is to give them safety training.

6.1.2

The course for supervisors should include legal requirements, company and administrative policies and safety aspects of the work likely to be undertaken by the supervisors. An outline of such a course is given in 6.3.1 of this section.

6.2 Safety Training for Workmen

Accident prevention training for workmen should incorporate the items listed in 6.3.2.

6.2.1 Integrated Practices

Safe working practices must be integrated into training for specific skills.

It is expected that those who have attended recognized training establishments will have received the necessary safety instructions.

6.2.2 Specialized Training

Before their training is complete, new employees and new entrants to industry are more susceptible to accidents. Contractor's must provide safety orientation and training for new employees.

Induction training should teach new workers to identify common on-site hazards and how to guard against them. It should also cover the main requirements of the

February 1993 - 6.0 Safety Training Page 52

company's accident prevention policy and instruct newcomers specifically in those areas which affect them personally (e.g., if it is company policy that safety helmets and protective footwear should always be worn, then this should be made clear and they should be told how and where to obtain them).

Suitable induction courses together with job training containing an integrated safety content will go a long way towards achieving safe working conditions. Site supervision, however, must ensure that correct job methods are being utilized and workmen are periodically reminded to be aware of hazards in the work place.

6.2.3 Use of Persuasion

The training providing skill and information should be supplemented by the techniques of persuasion. Persuasion has an important function and should not be overlooked in any comprehensive program. It is commonly applied by the use of posters which graphically indicate bad habits, pin-point the advantages of a safe working environment and give detailed information, advice, or instruction on special safety points to remember.

Posters can be useful provided that:

• They are designed with due regard for the industry and its type of operation. • They are displayed where workmen spend some time when not working and

specific posters are displayed where most appropriate (e.g., ladder hazards in ladder storeroom).

• They are mounted on properly designed and maintained bulletin boards. • They are changed at frequent intervals. • Only a few posters are displayed simultaneously.

Posters can stimulate thought on accident prevention, but they are no substitute for organized training. The most effective posters are those that help to reinforce safety training.

6.2.4 Course Requirements

An induction safety course for workmen should be aimed at specific hazards which they could encounter at a specific job site. A suggested outline of such a course is given in 6.3.2.


6.3 Scope of Training

Safety training needs to be ongoing if it is to accomplish optimum results. The program material and presentation should cover the safety subject and be interesting enough to hold the trainee's attention. A limited training effort, such as an occasional safety meeting, may prompt supervisors to do a better job for a short time, but interest starts to lag unless an effective safety training program is in place.

Good job safety instruction not only produces more skilled workers, but also impresses upon them the high value that the employer places on job safety. Frequent follow-ups and attention by the supervisor to correct work practices also help to create understanding and to eliminate resentment, which is a source of some undesirable work attitudes. (See 6.3.1.)

7.0 SITE PLANNING AND HOUSEKEEPING

This section outlines the procedure to be followed prior to and during a contract. It cannot claim to cover every type of contract that is likely to occur, but it does provide a detailed logical process to serve as a guide in deciding upon a plan of action.


Saudi Aramco Standards:

GI 1021.000 Street And Road Closure And Excavations, Reinstatement And Traffic Controls

SAES-P-123 Lighting; Illumination Requirements

SAES-B-007C Portable, Mobile and Auxiliary Fire-Fighting Equipment

Schedule 'D':

Saudi Aramco Safety, Health and Environmental Requirements (See Appendix A)

National Fire Protection Association:

NFPA 80-A Protection of Buildings from Exterior Fire Exposures

NFPA 231 - Appendix 'C'

Protection of Outdoor Storage

7.1 Initial Planning

Prior to the start of any contract, an analysis is made by the contractor to ensure that construction will be conducted in a safe manner. Similarly, accident prevention is analyzed, both at the planning stage and throughout the contract, so that the contractor will be able to eliminate or reduce accidents. Accident prevention is a real factor in the economic success of all contracts.

Among other factors that must be considered at the initial planning stage are: results of a Hazard Identification Plan, loss prevention program, protection of employees and equipment, transportation, lifting equipment, excavation, scaffolding and work in restricted areas requiring work permits.

7.1.1 Hazard Identification Plan

The contractor shall conduct a Hazard Identification tour with the Company and Saudi Aramco Loss Prevention representatives to identify potential hazards prior to construction start-up.

February 1993 - 7.0 Site Planning And Housekeeping Page 58

7.1.2 Loss Prevention Program

A loss prevention program required in Schedule 'D' for specific job-related activities part of proposed construction work will be developed and coordinated by the contractor's safety supervisor. Part of this program will be a ten-minute safety discussion with the workmen, at least once a week, on the hazards at the site and the procedures to be followed to prevent personal injury and minimize property damage.

7.1.3 Protection of Employees and Equipment

Schedule 'D' details the requirements to be followed by the contractor to reduce losses. It places the responsibility for the protection of men and equipment on the contractor and outlines general minimum acceptable standards.

7.1.4 Transportation

The contractor must provide transportation to and from the site for his employees.

Saudi Aramco requires that employees must be transported only in the passenger compartment of vehicles. (See Section I.13.) The provision of buses for larger sites will have to be considered.

9.0 PERSONAL PROTECTIVE EQUIPMENT

When a hazardous situation is recognized, steps should be taken to eliminate the hazard by engineering controls. Should it prove impractical to eliminate the hazard, then personal protective equipment must be used that meets the requirements of ANSI or equivalent standards. When it has been decided that personal protective equipment is required, steps must be taken to select the proper type of equipment and ensure that the supervisor instructs his employees in the use and care of that equipment, in accordance with the instructions provided by the manufacturer and Saudi Aramco. (See Table I.1.)

February 1993 - 11.0 Fire Prevention Page 72

9.1 Head Protection

Safety hats or helmets are rigid headgear made of materials designed to protect the head from impact, flying particles, electric shock, etc. Each helmet consists of a shell, a suspension cradle, and a chin strap.

9.1.1

Employees working in areas where there is danger of head injury from impact; from falling or flying objects; or from electrical shock and burns, shall be protected by protective helmets as per ANSI referenced standards or equivalent.

9.1.2

The suspension cradle gives a helmet its impact distribution qualities. It is therefore essential that it be properly adjusted to the wearer's head so there is a gap of at least one and a half inches between the top of the suspension cradle and the helmet shell.

9.1.3

Ancillary equipment such as ear muffs, welders shields, etc. can be obtained to fit on helmet shells. Holes should not be drilled into helmet to facilitate use of such equipment as this can seriously impair both the mechanical strength and the electrical resistance of the helmet.

9.1.4

Safety hats or helmets shall not be painted.

9.1.5

The complete helmet should be cleaned regularly with soap and water. Helmets should be scrapped following any penetration, high impact, or subjection to extreme heat.

9.1.6

A safety helmet should be worn by all persons at all times when on a construction job site; in an operating plant area; or whenever there are overhead hazards. Metal hard hats do not afford proper impact or electrical protection and, therefore, are prohibited from all Saudi Aramco work areas.

9.2 Eye and Face Protection

Protection of the eyes and face from injury by physical or chemical agents or light radiation, is of prime importance in an industrial environment. The type of protection selected will depend on the hazard, but it should be borne in mind that all eye protection and most face protection devices must be considered as optical instruments. They must be selected, fitted, and used with regard to both the type of hazard and the optical condition of


the user. (See Figures I.9 and I.9A.) The wearing of contact lenses is not recommended in areas where eye protection is required.

9.2.1 Eye Protection from Impact

Factors to be considered in selecting impact resistant eye protection include the degree of protection required and the comfort provided as required by ANSI or equivalent requirements. Four basic types of protection are:

1. Spectacles used for protection against frontal impact. When fitted with side shields, they afford limited protection against side impact and should not be worn while driving if they interfere with peripheral vision.

2. Flexible fitting goggles. A flexible frame surrounding the lens gives protection against flying objects.

3. Cushion fitting goggles. A rigid plastic frame surrounding the lens and a separate cushioned fitting surface on the facing contact area gives protection against flying objects.

4. Chipping goggles. Separate rigid plastic eyecups with lens. Designed in two shapes, one for individuals who do not wear spectacles and one to fit over prescription spectacles.

5. Chemical goggles.

9.2.2 Eye Protection from Radiant Energies

In addition to damage from physical and chemical agents, the eyes are vulnerable to the effects of radiant energy such as that produced during welding. Visible and non-visible bands of the light spectrum can produce harmful effects upon the eyes and special attention must be paid to the selection of eye protection from these hazards.

9.2.3 Face Protection

Face shields protect the face and neck from flying particles, sprays of hazardous liquids, splashes of molten metal, and hot solutions. Where required, safety spectacles and chemical goggles shall be worn under the face shield.

9.3 Hand Protection

The kind of gloves used depends primarily upon the material or equipment being handled and can be resistant against one or more of the following: heat, acid, caustic, slipping, wear, fire, oil, sharp edges, general wear and tear, cold, etc. (See Figure I.5.). Gloves should not be used near moving machinery as they can be caught and trap the hand before it can be withdrawn from the glove.

9.4 Foot Protection

Foot protection used must be manufactured to the referenced ANSI standard Z41-83 (or its equivalent). Safety footwear is available in many styles, with special soles to resist oil, abrasion, heat, and other abuses to which the footwear may be subjected. Comfort is particularly important for the wearer, so safety footwear must fit properly.


Approved safety footwear are sturdy work shoes with leather uppers and/or leather composition with steel toe caps. Soles and heels are "non"-slip type. Fashion type safety "toe" shoes with canvas, nylon and/or other soft composition uppers or soles are not considered safety shoes and are not approved by Saudi Aramco.

9.5 Hearing Protection

Increasing attention is being paid to the problem of excessive noise in industry. Noise can be defined as "any unwanted sound". The intensity of noise is commonly expressed in terms of decibels (dBA) and measured by a sound level meter. Medical authorities state that continual exposure to noise levels above 90 dBA for an eight hour day, five day work week may endanger a person's hearing. The safe period of exposure to a noise level is inversely proportional to the level of the noise. (See reference SAES-A-105, Noise.)

Hearing loss will result from over-exposure to excessive noise levels. Only after engineering and mechanical methods of reducing noise levels have been explored, should consideration be given to providing hearing protection to individual workmen.

Exposure to impulsive or impact noise shall not exceed the requirements of SAES-A-105, Noise.

Whenever it is infeasible to reduce the noise levels or duration of exposure to within the limits of SAES-A-105, hearing protection devices shall be provided and used. There are two types of hearing protection available, the plug type and the cup (or muff) type. The proper individual fitting of both types of hearing protection is critical as any sound leakage can seriously impair efficiency of these devices.

9.5.1 Ear Plugs

Ear plugs are placed into the canal of the outer ear. Materials used for these plugs are rubber, plastic, wax, foam or Swedish wool. Disposable types are preferred as they give good protection and are very sanitary.

9.5.2 Ear Muffs

Ear muffs cover the external ear to provide an acoustic barrier. The effectiveness of ear muffs varies considerably due to differences in manufacturer, size, shape, seal material, shell mass, and type of suspension. Head size and shape can also affect their performance. Liquid or grease filled cushions between the shell and the head are more effective than plastic or foam-filled types, but they would present material leakage problems.

The use of hearing protection devices shall be properly evaluated to ensure that the selected devices give the necessary noise attenuation and protection.

9.6 Fall Restraining/Arresting Devices

There are several types of fall restraining devices used throughout the construction industry. The two most commonly used ones are the full body safety harness and the safety belt. Harnesses are used for above ground work, where fall restraining and arresting protection is


required. Safety belts are used to restrain the wearer at his place of work. Safety belts should not be used as part of the fall arrest system. (See Figure I.6.)

9.6.1

Full body harnesses are required when working in areas with no guard rails at heights above 1.82 meters (6 feet) or for potential falls of six feet or greater. Exceptions shall require the review and concurrence of the Loss Prevention Department.

9.6.2

Special attention should be given to achieve a snug fit of the safety harness as it is easy for a man to slip through sound but badly adjusted equipment and fall.

9.6.3

No fall restraining or arresting device is any stronger than the point of attachment. Therefore, all users should be carefully instructed in the importance of a firm anchorage.

9.6.4

Fall restraining/arresting devices must be stored in clean and dry conditions away from sunlight, and must be thoroughly inspected both on issue and at the start of each shift.

9.6.5

Fall protection devices shall be capable of supporting a minimum dead weight of 2450 kilograms (5400 pounds). (Refer to OSHA 29 CFR 1910.66, Appendix C - 1991.)

The maximum length of standard lanyards shall be limited to provide for a fall of no greater than 1.82 meters (6 feet) except in the case of mechanical fall arresting devices which have been reviewed and received concurrence by the Loss Prevention Department. The lanyard shall have a minimum breaking strength of 2,450 kilograms (5,400 pounds).

All fall arresting/restraining devices and hardware shall be manufactured to ANSI or equivalent standards and fully described in the Hazard Identification Plan (HIP), including type, model and manufacturer.

9.6.6

During all operations conducted from a personnel platform (man basket) at any height above ground level, fall protection devices (lanyards) shall be secured to an anchorage point or a structural member located on the basket which can support a minimum dead weight of 2,450 kilograms (5,400 pounds).

American National Standards:

ANSI Z88.2. - 1980

Practices for Respiratory Protection

US. Bureau of Mines:

Respiratory Protection (See 30 CFR Part II)

10.1 Selection of Equipment

A wide variety of respiratory protective equipment is available. As each type is suitable for certain applications, it is necessary to develop an orderly method for determining the appropriate device to be employed.

Persons should not be assigned tasks requiring the use of respirators unless it has been predetermined by medical examination that the worker is physically able to perform the work and use the breathing apparatus properly.

Each user must receive instructions on the proper use and limitations of the device, as well as demonstrations and practice in how to fit and wear it. Personnel shall not be placed in a hazardous environment for which the respirator is not designed, such as a location where there is a lack of sufficient oxygen.


Consider the following factors when selecting a suitable respiratory protective device:

1 The nature of the hazardous operation or process. 2 The type of air contaminant, including its physical properties, chemical properties,

physiological effects on the body, and its concentration. 3 The period of time for which respiratory protection must be provided. 4 The location of the hazard with respect to a source of uncontaminated respirable air. 5 The state of health of the personnel or users involved. 6 The functional and physical characteristics of the respiratory protective devices. 7 The use of approved respirators only.

The contractor must know the specific hazards for which a given type of respiratory equipment is approved. He should not permit respiratory equipment to be used for protection against hazards for which it was not designed.

10.1.1 Requirements For Use

As with all personal protective equipment, respirators only work if you use them correctly. For face mask respirators, always make sure that the mask fits properly, that there is a tight seal and no air leakage. Proper fit is important to prevent contaminants from leaking in. Beards, dentures and facial bone structure can affect the fit of the respirator. Be sure to wear the right respirator for the hazard. Always keep the respirator clean and well-maintained. Never alter or modify the respiratory equipment. Finally, follow manufacturer's specifications for proper cartridge use and established safety procedures. Do not hesitate to consult your supervisor if there are any questions concerning your personal respiratory protection.

10.1.2 Misuse

Workers sometimes consider respiratory equipment a nuisance, not realizing that failure to wear it may endanger their lives. This attitude can be changed by education and training. However, as the risk of injury or death is very real when safety precautions are ignored, any worker refusing to wear the necessary respiratory equipment will not be allowed to work without it.

Common misuses of respiratory protection equipment include:

a. Using air-purifying (chemical cartridge type) respirators when toxic levels are above the respirator-rated capacity.

b. Using air-purifying (chemical cartridge type) respirators in oxygen deficient atmospheres.

c. Using incorrect cartridges or filters for the type contaminant and the concentration encountered.

d. Using defective or improperly inspected equipment. e. Using equipment without having received adequate on training on it.


10.1.3 Hazardous Substances

Protection is required against those hazardous substances which can be inhaled into the respiratory system, ingested via the digestive tract and absorbed into the skin causing systemic injury to the human body. Hazardous substances which can enter the body through the respiratory system, the digestive tract and the skin include, but are not limited to, the following:

• Asbestos • Creosol (cresylic acid) • Hydrogen cyanide (hydrocyanic acid) • Tetraethyl lead and its compounds • Mercury and its compounds • Nitroglycerine • Organic phosphate insecticides • Solvents

10.1.4 Contaminants

Air supplied to respiratory equipment must be free from contaminants. (See GI 8.003.) Respirable air shall be controlled to the following conditions at all times:

1 Oxygen, not less than 19-23% vol. 2 Carbon monoxide, not more than 10 parts per million (ppm) 3 Carbon dioxide, not more than 0.10% vol. 4 Oil mist, not more than 5 mg/m3 @ NTP 5 Water vapor, not more than 0.76 mg/l 6 Particulates, none

The above standards are based on Compressed Air Gas Association (Table No. 1) and referred to as Grade 'D' breathing air. Respirable air quality must meet this standard, at a minimum.

The air delivered to the user must be less than 100oF (38oC) and supplied at 6 standard cubic feet per minute (6 SCFM). Air cooling devices (e.g. vortex tubes) may be necessary.

10.2 Respiratory Protective Devices

Respiratory protective devices can be classified as follows:

1 Air purifying respirators 2 Supplied air respirators 3 Self-contained breathing devices

10.2.1 Air Purifying Respirators

10.2.1.1 Gas Masks

The gas mask type of respirator consists of a face piece and filter. No one chemical agent has been found that will remove all gaseous contaminants, so the canister must be carefully chosen to fit the


specific need. A canister designed for a specific gas will give longer protection than a canister designed for a multitude of gases and vapors. Canister gas masks with full face pieces are effective against higher concentrations of contaminants. However, they do not provide protection against oxygen deficiency.

10.2.1.2 Chemical Cartridge Respirators Chemical cartridge respirators consist of a face piece (usually half mask) connected directly to one or two small containers of filters/chemicals. The chemicals used are similar to those found in gas mask canisters, but cartridge respirators are for use only in atmospheres not immediately dangerous to life or health. An area where the chemical cartridge respirator works very well is in spray painting. It is critical that the cartridge be matched to the specific application.

10.2.1.3 Particulate Filter Respirators (Dust Respirators)

A particulate filter respirator protects against the inhalation of nonvolatile particles. The major items to be considered are: 1 The resistance to breathing offered by the filtering element; 2 the adaptation of the face piece to faces of various sizes and

shapes; 3 the fineness of the particles to be filtered out, and their toxicity.

10.2.2 Supplied Air Respirators

A supplied air respirator permits the user to breathe respirable air while working in a hazardous atmosphere. Important advantages are simplicity of design, usage under diverse conditions, and good protection (when properly selected, adequately supplied with respirable air, and used for the purposes for which they were designed and approved).

10.2.2.1 Air Line Respirators

The air line respirator (see Figure I.8) is suitable for respiratory protection in atmospheres not immediately hazardous to life. Equipping the respirator with a small cylinder of compressed air to provide an emergency air supply qualifies the respirator for use in immediately hazardous atmospheres. It is particularly suited to some types of jobs because it is light and may be worn for long periods of time without appreciable discomfort. For example, it is often used for spray painting, insecticide spraying, welding, metalizing and prolonged production work in hazardous areas.

There are two basic types of air line respirators: 1 the continuous flow, 2 the pressure demand flow.


The continuous flow respirator may be assembled to a half mask, full face piece, or hood, whereas the demand flow type must always be used with a tight-fitting face piece.

1 In the continuous air line respirator, a set amount of air is continuously fed to the face piece. The amount is regulated by an air control valve of special inlet design which is not susceptible to accidental changes of the setting even when jarred. A slight positive pressure on the inside of the mask is always maintained to prevent inward leakage of the contaminated outside atmospheric air.

2 The pressure demand flow air line respirators are normally used when air must be conserved, as may be the case when the supply is from a cylinder of compressed air. They contain a regulator at the lower end of the breathing tube. This permits air to flow under slight preset positive pressure to the face piece only when the wearer breathes.

10.2.2.2 Abrasive Blasting Respirators

Abrasive blasting respirators are used to protect personnel engaged in sand or other abrasive blasting operations.

The requirements for this type of respirator are the same as those for an air line respirator of the continuous flow type with the addition that mechanical protection from abrasive particles is needed for the head and neck.

10.2.2.3 Air Supplied Suits

The most extreme condition requiring respiratory equipment is rescue or emergency repair work done in atmospheres which are extremely corrosive to the skin and mucus membranes, in addition to being acutely poisonous and immediately hazardous to life.

For these conditions, full suits of impervious clothing with respirable air supplies are available. This equipment must be used only by well-trained and qualified personnel. Consideration must be given for the clearance of safety equipment through manholes and other accessways. (See Figure I.9.)

10.2.3 Self Contained Breathing Apparatus (SCBA)

When entry into a hazardous atmosphere is necessary, self contained breathing apparatus shall be used. This equipment typically consists of a high pressure cylinder of air, a cylinder valve, a regulator, a face piece and tube with an exhalation valve. The need to have the mask properly fitted before use is important. A person who wears glasses or who has a beard cannot wear this type of breathing apparatus as a proper seal cannot be obtained between the mask and face.


SCBAs must be used in lieu of airline respirators when the distance from the source of fresh air supplied via the air line hose is greater than 91 meters (300 ft) per ANSI Z88.2-1980. However, an exception from this requirement is made in an emergency situation where use of such equipment is necessary to escape from a hazardous condition.

10.3 Training

In many cases, respirators are used in emergency situations where there is heightened physical demands on the body, due to stress and excitement. Under such conditions, it is essential that the potential users have been thoroughly trained and are medically fit (per TM - 3 or equivalent) to cope with the increased level of physical activity and stress. The local Loss Prevention Division and the Industrial Hygiene Unit will assist contractors in the selection and use of respiratory protective equipment.

10.4 Safety Precautions

When air supplied respirators are used, the following safety precautions are required:

1 Breathing air compressors shall have: • Pressure Relief Valve • High temperature alarm • Periodic carbon monoxide (CO) testing to ensure it meets the CGA Grade 'D' limit • Breathing air tested to meet requirements. (See section 10.1.4.)

2 Proper training of employees in the use of this equipment. 3 Fit testing of mask/hood prior to each use. 4 Employees determined by a medical evaluation to be physically fit to use equipment. 5 Proper cleaning and inspection program for equipment. 6 Written standard operating procedures for using the equipment. 7 A rescue man with a self-contained breathing apparatus (SCAB) is required when

equipment is used in immediately dangerous to life and health (IDLH) atmospheres. 8 Life lines shall always be attached to the safety belt worn by employees using a

respirator.

10.4.1 Air Compressors

• Air compressors shall operate at 245oF and 150 psig maximum. (See manufacturers' specifications.)

• Intake air filters to compressors and outlet filters to operator mask/hood are required.

• Air supplied respirator's maximum intake temperature and pressure are 140oF (60oC) and 125 psig respectively. Filter outlet temperature to operator's mask/hood is 100oF maximum. The air.supply rate is 6 CFM for hoods without vortex tube and 25 CFM for hoods with vortex tube.

National Safety Council Accident Prevention Manual for Industrial Operations

NFPA: National Fire Codes NFPA 231-Appendix C, Protection of Outdoor Storage. "Fire Safety Checklist for Evaluating Construction Materials Store Yard"

11.1 Before the Job Starts Construction within a petroleum industry complex requires careful planning since plants and support facilities being constructed are frequently next to those already in operation. An accident at a construction site can have serious effects on a nearby oil or gas facility and vice-versa, because of a large amount of fuel present at both locations. The factors which must be considered before the job starts include site preparation, work permit schedules, types of work permits required and type/quantity of equipment required on-site.


As part of this process, the contractor must take into account the potential hazards that can be encountered on site; protection of machinery and equipment; control of ignition sources; storage of flammable and combustible materials; housekeeping; staff training; and end-of-shift checks. These subjects are addressed in the Hazards Identification Procedure prior to construction start-up in Appendix A of this manual. This section focuses on means of avoiding and controlling fires.

11.2 Layout

Good layout helps ensure the project can be carried out efficiently. Overall requirements for site planning are in Section 7. (See Appendix C attachment). The following principles of project layout and organization can help minimize fire risks:

11.2.1

Avoid congestion around machinery and equipment where there is a high level of activity and traffic.

11.2.2

Operations having a high fire risk, such as welding and spray painting, should be isolated from flammable and explosive materials or specially protected.

11.2.3

Be sure to provide adequate emergency access and egress.

11.2.4

Storage of flammable and explosive materials in the plant site should be restricted to minimum quantities necessary for an uninterrupted cycle of operations; use a larger, secondary storage site outside the plant area where possible.

11.3 Equipment Protection

Some items of plant equipment need special handling and care after they arrive on site and until they are commissioned. Examples are computer (and other electronic instrumentation and control gear) and large pumps and compressors. Such equipment should be covered and protected against possible damage that could result from its exposure to normal construction activity, dust, paint spray, etc. Consideration should also be given to protecting it against fire, which could be caused by storing it near combustible material and against water or other fire fighting agents that might be used to put out a fire.


11.4 Control of Ignition Sources

Compliance with work permit procedures and conditions protects against possible ignition of oil or gas from process operations. The contractor must also take steps to prevent ignition of construction materials, lubricants, and fuels used in the job itself.

11.4.1

Electrical equipment should be checked regularly for defects.

11.4.2

Smoking is permitted only in designated areas.

11.4.3

Welding equipment, asphalt kettles, heating appliances and other open flames or hot surfaces should be segregated from combustible materials.

11.4.4

Beware of indirect sources of ignition: hot welding slag dropped from a height for example, or sparks from a fire under an asphalt kettle are familiar examples of this.

11.4.5

Open fires and/or open burning of materials are strictly prohibited. Authorization must be obtained from Saudi Aramco Fire Protection Department.

11.4.6

Proper bonding and grounding techniques shall be used for any operation where static electricity could become an ignition source.

11.5 Flammable Liquids

Flammable liquids are those that can produce a flammable mixture in air at ambient temperature. In Saudi Aramco, this is defined as a fluid (liquid or gas) having a flash point of 55oC (130oF) or lower. Care in handling flammable fluids is of prime importance.

11.5.1 Storage

All flammable liquids must be kept in securely capped metal containers or steel drums on which the contents are clearly marked. Gasoline, acetone, spirits and other volatile liquids with flash points below 32oC (90oF) should be kept in strong metal lockers located in well-ventilated, non-combustible huts or sheds. Drums containing flammable fluids shall be provided with proper bung vents. Flammable storage areas must be securely locked (or fenced), posted with a warning sign "Danger: Flammable Area" and must be located at least 15 meters (50 feet) away from the nearest building or storage area for combustibles. No other materials should be stored with flammable liquids.


Flammable gases in cylinders (acetylene, propane, etc.) shall be segregated from other materials, preferably under an open, well-ventilated sun shade. Oxidizing gases (oxygen, chlorine, nitrous oxide, etc.) shall be stored separately.

11.5.2 Handling of Flammable Liquids (Reference NFPA 30)

In handling, the following precautions should be observed: 1 Transportation must always be in (closed) metal containers. (Plastic

containers are prohibited.) 2 Transfer operations should be carried out with funnels and there should be

no open flames within 15 meters (50 feet) of the operation unless conditions warrant greater clearance.

3 Containers are to be grounded and bonded during transfer operations. 4 Screw tops and stoppers should be replaced immediately. 5 Any metal container holding flammable liquid must be a FM (or UL)

approved type of safety container.

11.5.3 Ventilation

Gasoline and diesel powered equipment should only be used in well-ventilated areas. Exhaust pipes should be kept away from combustible materials. Engines must be stopped before refueling takes place.

11.6 Combustible Materials

Although the main material used in the construction of plants for the petroleum industry is non-combustible steel or concrete, on a construction site many materials are potential fuel for a fire: packing material, scaffold planks, form lumber, electrical insulation, tires and other rubber goods, lubricating oil and grease, and diesel fuel, in addition to the flammable liquids (fuels, paints, solvents) mentioned above. Therefore, daily site clean up of combustible materials is required to reduce fire hazards.

11.7 Housekeeping

Rubbish, accumulated at a job site, provides a good starting point for a fire. Waste should be removed at regular intervals and always at the end of a working day. Metal bins with close-fitting lids should be provided for oily rags, wood shavings, and other highly combustible wastes. Use non-combustible absorbents to remove spills or leaks of oil. Contents of ash trays should not be mixed with other waste. Good housekeeping on the site can eliminate many of the situations where a fire can start.

11.8 Emergency Equipment

The Fire Protection Department area offices can assist in training Saudi Aramco employees in the proper use of fire fighting equipment. (See GI 1781.001. Inspection and Maintenance of Fire Protection Equipment.)

Each contractor has a contractual obligation to provide and maintain adequate, easily accessible fire extinguishers on the job site (Schedule 'D'). The contractor should consult


with the local Fire Protection Unit for advice on selection of such equipment. There are three types of fire extinguishers normally found on construction sites: water, carbon dioxide and dry chemical types. Contractor personnel should be aware of the fire fighting equipment available on site and be familiar with its use.

11.8.1 Water-Type Fire Extinguisher

Water extinguishers should be available around sites where there will be Class "A" material, such as wood, paper, waste material, or packing crates. The typical portable water extinguisher comes in a 9.5 liters (2-1/2 gallon) size. On construction sites within Saudi Aramco facilities a pressurized system of fire water hydrants and hoses will normally be available, so this type of extinguisher will have limited use.

11.8.2 Carbon Dioxide Type Extinguisher

The carbon dioxide (CO2) type extinguisher is normally used for controlling electrical fires. These fires take place in motors, switch-gear, and so forth and are usually very easily controlled by de-energizing the circuits that supply the power. The advantage of using CO2 in this particular instance is that it leaves no residue in the mechanisms of the electrical equipment and, therefore, does not further contribute to the damage.

11.8.2.1 CAUTION

A CO2 extinguisher should never be used in enclosed areas where people are present, because the gas displaces oxygen from the immediate environment. When the oxygen level in the environment is reduced sufficiently to put out a fire, the oxygen level is also incapable of supporting human life.

11.8.3 Dry Chemical Type Extinguisher

A dry chemical type extinguisher is normally used in controlling Class "B" fires in flammable liquids. A dry chemical extinguisher normally comes in portable 9 kilograms (20 pounds) and 13.6 kilograms (30 pounds) sizes. A larger wheeled extinguisher of 68 kilograms (150 pounds) and above is available, but is usually found only within petroleum operating areas. Some dry chemical extinguishers today have a powder which is good in controlling Class "A", "B", and "C" fires. This multipurpose ABC powder gives this particular fire extinguisher a good chance of controlling any type of fire involving a wood, a petroleum liquid, or electrical equipment.

11.8.4 Pressurized Water

Where a pressurized water system is available on site, the contractor is responsible for supplying hoses and nozzles. Since most fires at construction sites involve Class "A" materials, they can be fought with water. Charged water hoses, ready for use, are a necessity. If there is no permanent system installed at a particular location, a water tanker and portable water extinguishers will have to be supplied in order to take care of any Class "A" fires.


11.9 Reporting a Fire

Every fire, including those extinguished by contractor personnel, should be reported to the Saudi Aramco representative. The Fire Protection Unit will inspect the area, to offer suggestions for preventing a recurrence, and to ensure the contractor has re-established his fire fighting capability by recharging extinguishers or replacing equipment.

The emergency telephone number used for reporting a fire or any emergency that requires Saudi Aramco assistance is 110. The contractor must ensure that this number is posted at all telephones and that instructions are placed indicating how to report the emergency correctly.

11.10 End-of-Shift Checks

A routine inspection shall be made at the end of the working day to see that everything is left in a safe condition. The following itemized checklist shall be followed:

• Clean-up and removal of rubbish and waste materials. • Switch off electrical equipment at the mains. Separate circuits should be

provided for security lights and other equipment that has to be left turned on.

• Cover valuable equipment to protect it against dirt and against the effects of water that might be used in an emergency.

• Make a special check of smoking areas, hot equipment, welding areas, etc. to be sure there is no possibility of delayed ignition resulting in a fire.

• Return flammable liquids and gas cylinders to designated storage areas.

February 1993 - Fire Prevention Page 95

FIGURE I.9: KNOW YOUR FIRE EXTINGUISHER

MAINTENANCE:

Maintenance should comprise of a monthly check by proponent organization - Check extinguisher is in correct location, access is unobstructed and extinguisher is clearly visible. Check contents gauges, where fitted, indicate extinguisher is serviceable. Check for signs of leakage, corrosion, or physical damage. Check seals are unbroken and up to date inspection tag is fitted. If in doubt, contact your local fire control unit.

February 1993 - Construction Safety Manual: Radio Communications Page 96

12.0 RADIO COMMUNICATIONS

In a widespread area such as that covered by Saudi Aramco operations, it is not cost effective to lay down telephone lines and establish subsidiary installations for communication. It is more feasible to develop a radio communications network instead. The continuous development of the Saudi Aramco radio communications system has enabled us to convey messages to the most remote corner of the Company's operational area.

This section is mainly concerned with the two-way radio network which is installed in vehicles, offices, outlying plants and allied facilities. This network is extensively used by many employees in their day-to-day business. Standard procedures must be followed in these radio operations.

12.1 Equipment

There are a minimum of three types of radio sets used in the Saudi Aramco network today: the mobile radio set, the stationary radio set with remote control, and the portable hand radio set.

12.1.1 Remote Control Unit

The remote control units located in offices are used to control radio equipment at some other location. The unit controls used by operating personnel are the volume control, hand set switch, and the frequency switch. All other controls must be set by technical personnel.

12.2 Safe Operation

Adjustment of equipment must always be carried out by authorized personnel. Unauthorized tampering with equipment can result in electric shock or equipment malfunction leading to circuit interference.

Under certain circumstances, radio waves can cause ignition of electric blasting caps. Radio equipment must be shut down within 91 meters (100 yards) of any blasting operations or where electric detonators are used or stored.

Water Damaged Equipment:

Vehicle drivers and maintenance personnel are requested to exercise great caution when washing vehicles containing radio equipment.

12.3 Radio Phrases

AFFIRMATIVE: This means Yes

BREAK: The work BREAK means the message will continue, but due to the length of the message the operator will break the circuit to allow the reception of EMERGENCY messages.

CORRECTION: This means that An error has been made; the correct message is ...

DISASTER: When used on Company communications systems, DISASTER warns all operators that a sudden misfortune has occurred, causing either loss of life, property, fire, or a combination of the three. All operators must stop transmitting unless involved in the disaster and should standby unless told to transmit by Disaster Control or the Disaster Control Post.

DISASTER DRILL: This is an exercise for training personnel to handle disaster situations.

HOW DO YOU READ?: This means that the operator is trying to determine if the message is being received well.


MAYDAY: This is an international radio distress signal which is primarily intended for ships and aircraft requiring assistance to save human lives or property.

NEGATIVE: This means No.

OUT: An operator using the word OUT at the end of a transmission indicates that he is finished with the communications circuit and any other station may begin its call.

OVER: This means that the transmission of a message has ended, but one station is waiting for the other to transmit.

OVER AND OUT: Do not use this phrase.

PRIORITY TRAFFIC: This is a message having preferential rating over the routine. The expression "I have priority traffic" means the operator has listened to the messages being transmitted and has determined that his message is of greater urgency.

READ BACK: This means that the operator wants to make sure that his message has been correctly understood.

RESUME TRAFFIC: All stations are free to transmit routine messages.

ROGER: This means that the operator has received and understood the message and accepts responsibility to carry out any instructions therein.

SAY AGAIN: Do not use the word "repeat". If a message is to be repeated, the operator shall instruct the station to "say again your message".

SAY EVERY WORD TWICE: This phrase is used when the operator is having trouble understanding, and wants each word said twice.

SPEAK SLOWLY: This phrase is used mostly in cases where technical difficulties are causing the circuit to cut in and out.

STANDBY: Any or all operators told to STANDBY shall cease further use of the communications circuit until further notice.

TRAFFIC: The information or signals transmitted over a communications systems.

URGENT TRAFFIC: A message requiring the attention of all operators.

VERIFY: Check with originator and make certain the message is correct.

12.4 Phonetic Alphabet

In a radio message, some letters of the alphabet are likely to be confused with others: as "B" with "P" and "D" with "T". A standardized international phonetic alphabet for radio operators is in use to clear up such ambiguities. Whenever a word is not properly understood by the receiver, it is advantageous to utilize the Phonetic Alphabet. For example, an operator intends to make clear "ABQAIQ". He will spell it out like this: "A" as in "ALPHA"; "B" as in "BRAVO"; "Q" as in "QUEBEC"; "I" as in "INDIA"; and, so on. Use the phonetic alphabet which is listed which follows:

12.5 International Communications Union Agreement

All Company communications systems and networks come under the regulations of the International Communications Union Agreement. The Saudi Arab government is a signatory of the Communications Agreement and a member of the International Telecommunications Union (ITU). Regulations which shall be binding on all members include the operating of telegraph, telephone and radio. Any violation or infringement of any communication system or network shall be reported to the violator's administration by the control organization, stations, or inspectors detecting them.

All stations must be established and operated in such a manner as not to result in harmful interference to associated members or members of recognized private operating organizations.

NOTE: All stations are forbidden to carry out the following: unnecessary transmissions; the transmissions of superfluous signals; or false (or deceptive) distress, safety, or identification signals.

Use of profane or obscene language is a violation of the International Agreement.


Tampering with equipment is highly dangerous because of the high voltage involved. Adjustments to equipment are only to be made by competent and authorized personnel. Tampering can also cause off frequency operation and other technical problems which are violations of the ITU Agreement.

12.5.1 Monitoring of Circuits

Most voice transmissions are transmitted by radio waves and can easily be monitored by outside agencies. It is forbidden to disclose or divulge any information intercepted over the Company communications systems.

12.5.2 Secrecy Act

All member nations of the ITU bind themselves to the Secrecy Act which states: "They will take the necessary measures to prohibit and prevent:

* The unauthorized interception of radio communications not intended for public use.

* The divulgence of the contents, simple disclosure of the existence, publication, or any use whatever, without authorization, of information of any nature obtained by the interception of radio or telephone communications."

Supervisors should be especially alert for violations of this kind and use maximum disciplinary action toward violators.

12.5.3 Penalties

All persons operating the communications systems will be held responsible for any improper operation and will be held subject to disciplinary action.

12.6 Message Priorities for Company Operations

1 MAYDAY

2 PAN/DISASTER

3 DISASTER DRILL

4 SAFETY SIGNAL (Number 3 Priority - International Frequencies)

5 PRIORITY TRAFFIC

6 ROUTINE


12.6.1 MAYDAY

(Broadcast to all stations)

When MAYDAY is spoken three times and followed by the words: "this is (the call station, station identification, or other identification of the mobile station)", indicates that a ship, aircraft, or other vehicle is threatened by grave and imminent danger and requires immediate assistance to save human life or property.

The message has absolute priority over all other messages. When the message is heard, all stations shall stop transmitting and listen to the message. The nature of distress may be such that the operator may not be able to complete the message or repeat.

International Search and Rescue Monitor Stations shall 'fix' the bearings of the signal and alert ships and aircraft in the area to assist with the rescue.

All persons operating radio equipment must be thoroughly acquainted with this type of priority message.

12.6.2 URGENCY SIGNAL

(International PAN; Company DISASTER)

This message is usually directed to a particular station. PAN/DISASTER, when spoken three times and followed by the words: "This is (the call sign or station identification)", indicates that the station has a critical emergency concerning injury, oil operations or other extreme operating situation. Messages of this nature carry priority over all messages except MAYDAY. Company operators use the word DISASTER. Within Company operations DISASTER has the same priority as the word PAN for those operating on international circuits or frequencies.

12.6.3 DISASTER DRILL

At various times the Company conducts training exercises which are associated with familiarization and indoctrination programs. At the beginning of such a drill, radio stations will announce "A DISASTER DRILL is being conducted", followed by the name of the area. When a DISASTER DRILL is in progress, all stations whether mobile or fixed must standby, except those having MAYDAY, URGENCY, or DISASTER messages. The difference between DISASTER and DISASTER DRILL must be thoroughly understood.

12.6.4 SAFETY SIGNAL

No. 3 Priority - International Frequencies

This need only be understood by those operating on international circuits or frequencies. The French pronunciation of SECURITE will be spoken three times and followed by the station identification. The SAFETY SIGNAL is used


when a station is going to broadcast a message concerning the safety of navigation or giving important meteorological warnings.

12.6.5 PRIORITY TRAFFIC

Repairs to facilities involved in disasters should be classified as PRIORITY TRAFFIC.

12.6.6 ROUTINE

All messages except those classified above should be ROUTINE.

12.7 Distress Messages

(Forms and Examples)

12.7.1 MAYDAY

1 Distress Signal

The distress signal is MAYDAY, MAYDAY, MAYDAY followed by the name of station or station call letters repeated three times.

Give location, first.

Give the nature of the distress, second.

Give the kind of assistance required.

Complete message with any other information which can be of assistance to rescue operations.

2 Stations Receiving Message

From the location given, the receiving stations can determine if they are in the immediate vicinity. All stations shall cease transmission. The station in the immediate vicinity shall acknowledge receipt by transmitting the following message: "(Give name of station in distress; repeat three times) - This is the (name of station), Roger, your Mayday Message."

This station assumes the full responsibility of a control station for all further radio transmissions and all other stations remain off the air unless directed to transmit by the control station.

By virtue of acknowledging the MAYDAY message, the receiving station assumes control and becomes fully responsible. It may use any means at its disposal to carry out the rescue operation.


3 End of Mayday Distress

When the distress traffic has ceased or when silence is no longer necessary on a circuit or frequency which has been used for distress traffic, the control station shall transmit the following message:

"To all stations, to all stations, to all stations - This is (control station identification, repeated three times) distress traffic has ended with (station in distress identification). All stations resume normal traffic."

The message should be repeated at intervals in order to assure that all stations standing by receive the message.

IMPORTANT: The transmission of MAYDAY messages for the purpose of training is not permitted under any circumstances.

12.7.2 Urgency Signal

This signal indicates that the calling station has a very urgent message to transmit concerning the safety of a person, ship, or aircraft.

1 Signal

Radio operators, operating on international circuits or frequencies, shall be alert for the urgency signal which is PAN, repeated three times followed by the station call letter or identification. The Company equivalent to urgency signal is DISASTER.

2 Response

All stations shall cease transmitting and listen to the message that follows. If the stations receiving the message can be of any assistance, they shall acknowledge and render all assistance possible; otherwise, they shall cease transmission until the urgency traffic has been cleared.

3 Procedures

All persons operating Company communications equipment shall be familiar with the word DISASTER. When it is heard, they shall cease transmitting until the DISASTER is over. The procedures are outlined in the General Instruction Manual, under Disaster Procedure, Abqaiq, Dhahran, Ras Tanura.

4 Return to Normal

When the disaster has ended, the responsible parties outlined in the General Instruction shall clear the radio circuits for normal traffic.


12.7.3 Priority Traffic

Repairs to facilities involved in disasters would be classified as priority traffic and the priority would depend on the situation.

The issuer will grant the work permit after he has visited the site with the receiver, reviewed the hazards applicable to the particular job, and is satisfied that the work can be done safely. If the work contemplated involves any change, addition, or deletion in the facility, the work should be reviewed by an engineer and appropriate authorization is necessary.


Both the issuer and the receiver must hold valid work permit certificates issued by Saudi Aramco.

1.2.1 Power Distribution Department Clearances Power Distribution Department (PDD), issues clearances to enable work to be accomplished on high voltage electrical apparatus that has been de-energized and isolated from the power system in an approved manner. These clearances are issued by PDD dispatchers in addition to any work permits that are required.

Usually clearance receivers are PDD employees. Non-PDD employees and contractors should request PDD Electric System operators for assistance.

The following instructions apply to PDD clearances:

PDD 3.0: Definitions of Terms and Approved Abbreviations PDD 10.0: Power Distribution Operations PDD 11.0: Hold Orders, Clearances and Permission to Test

1.3 Precautions

1.3.1 Checklist

Each permit contains a checklist of precautions against common hazards. Such a list cannot include precautions against all hazards. It is the duty of both the issuer and the receiver to review the job, anticipate what hazards might arise, check for flammable gases in the area and see that proper precautions have been specified on the permit before it is signed.

1.3.2 Clear Area

One specific precaution applying to all work is to clear the area of people not required for the job to avoid their being exposed to unnecessary hazards. If people enter an area where they could be exposed to undue danger, the work should be stopped until they are cleared from the area.

1.3.3 Work Stoppage

If conditions change or become unsafe during the course of work, the issuer or local supervisor may stop the work and cancel the permit.

The receiver has the responsibility to stop the work and advise the issuer or supervisor any time he feels the safety of the job does not meet the conditions of the work permit.

1.4 Handling of Issued Work Permit

A work permit is valid for only one shift, but it may be extended for one additional shift with proper approval. Exceptions in excess of 16 hours may be granted in special cases, provided certain precautions are taken. (See GI 2.100 for details.)

The receiver of the work permit must keep the permit posted at the job location at all times.


The receiver of a work permit must keep a copy in his possession or within view of the job site for the duration of the job, so that it may be presented upon request. If the receiver leaves the job site, he shall give the permit to a responsible senior crew member to keep until he returns. The issuer, receiver and the senior crew member must sign the work permit transferring the work permit to the senior crew member.

1.5 Closing Out and Filing the Permit

When the job is completed or at the end of the shift, each work permit must be closed out by both issuer and receiver. The only exception shall be when the distance and remoteness make signing impractical, and it is so stated when the work permit is issued. The work permit will be filed and kept by the issuing department for three months.

1.6 Certification

In order for a person to be a certified receiver of work permits, he must attend the work permit Receivers Course conducted by the Loss Prevention Department and pass a test on work permit System (GI 2.100) given at the end of the course.

The superintendent of the construction organization will assure Saudi Aramco by his signature that his employee knows both the general instruction and his job. Contact the local Loss Prevention office for work permit certification information.

Records of current certificate holders, with their names and the dates issued, must be kept by each superintendent or organization head.

1.7 12 Rules on Work Permit Procedure (See below)

1.8 Hold Tags and Multiple Lockouts

1.8.1 Instructions contained in GI 6.012 outline the use of tagging and lockout for controllers which are to be held inoperative or for work clearance.

1.8.2 The purpose for the Lockout System is to render controllers inoperative, i.e., circuit breakers, disconnect switches, valves, etc. on any systems (electrical, steam, hydrocarbon, water, acid, etc.), where the operation of the control device could be hazardous to personnel working on the system.

1.8.3 Hold tags and locks are primarily intended to protect the individual doing the work from being injured by an inadvertent start-up.

1.8.4 Work permit issuers and operations supervisors shall ensure that hold tags and lock outs are used and so noted on the work permit. The use of hold tags/lock outs shall be strictly enforced.


TWELVE RULES ON WORK PERMIT PROCEDURE

1) Issuer and receiver must inspect job site together before signing the work permit.

2) Issue the correct permits for the job - hot, cold, vessel or confined space entry, and/or gas release. Two or more permits may be required for the job.

3) Issuer and receiver must both have in their possession a valid work permit certification card (issuer and receiver respectively).

4) J-W Sniffer gas test and/or H2S gas test and/or oxygen analysis test must be made before issuing work permit.

5) Job description and equipment used must be clearly stated on the work permit. Be specific, issue permits for a single pump, drum, etc.

6) All tick boxes must be correctly filled in and gas readings indicated.

7) Proper lockouts, hold tags, and blinds must be used where applicable (multiple clips with lock, and/or chains with padlocks).

8) Work permits should be issued for the specific period of time required to complete the job.

9) To extend time work permit beyond one shift, the oncoming shift issuer must inspect job site, write in extended time and sign permit.

10) Special precautions such as requirements for fire watch, Scott air packs, life lines, barricades, etc. must be written on the permit.

11) The work permit must remain on the job site in a conspicuously visible place while work is going on. If an emergency develops, the permit must be withdrawn immediately and all work stopped without questions.

12) The work permit must be closed out after a job is completed. Issuer and receiver must inspect the job site and sign off the work permit.


LOCK OUT AND TAG

Workers may be injured while working on equipment when the controls have not been locked and tagged in the off position. People do make mistakes and start equipment on which maintenance men are working; vibrations and ineffective mechanisms can cause controls to move or valves to open. Protection is simple: lock the control in the off position and prevent an accident.

Saudi Aramco has special rules requiring the use of locks on switches and controls when it would be unsafe to work on an energized or operating system. Each supervisor of operations and maintenance should know the rules in GI 6.012 - Isolation, Lock Out and Use of Hold Tags.

When more than one man is going to work on a system or on a number of pieces of equipment within the system, the multiple lockout clip enables each man to lock out the circuit or machine control. If your man can't get his lock on the clip, work should not proceed until a suitable clip is found. Clips may be ordered under stock number 21-350-487; locks under stock number 08-323-261; tags under stock number 39-378-419. Locks belonging to contractor personnel must have one key only and should be compatible with the Saudi Aramco system. Contractors will establish their own lock issuing procedure complete with logging and a numbering system.

Note: Contractors are required to establish a lock out and TAG system compatible with the Saudi Aramco system as part of the contractor Loss Prevention Program plan requirements of Schedule 'D'.

Tags are useful to tell who is working on the equipment and who authorized the shutdown. Teach your men the lockout procedure and insist they follow it.

2.0 EXCAVATIONS, TRENCHING AND SHORING

Accidents due to cave-in can occur for excavations which are not shored or otherwise supported. Even rock that looks solid from a cursory inspection can collapse without warning. The sides of an excavation may need to be suitably shored, benched or sloped back to a safe angle of repose, depth, and soil composition.

Other types of excavation accidents are caused by contact with underground pipes and cables, by falls of equipment and persons, by persons being struck by excavating equipment, and by hazardous atmospheres.



GI 1021.000 Street and Road Closure, Excavation Reinstatement and Traffic Controls (See Appendix D)


Saudi Aramco Engineering Standard:

SAES-A-111 Borrow Pit Requirements

OSHA Safety And Health Standards:

29 CFR 1926 Subpart P Excavations

DEFINITIONS:

1. Excavation

Any man-made cavity or depression in the earth's surface, including its sides, walls, or faces, formed by earth removal and producing unsupported earth conditions by reason of the excavation.

2. Trench Excavation

A narrow excavation made below the surface of the ground. In general, the depth is greater than the width, but the width of a trench is not greater than 4.5 meters (15 feet).

3. Accepted Engineering and Construction Practices

Plans for excavations and protective system methods shall be submitted to Loss Prevention before work start up.

February 1993 - 2.0 Excavations, Trenching And Shoring Page 126

4. Protective Systems

Methods used to protect employees from cave-ins, from materials that could fall or roll into the excavation onto the workers or from collapse of adjacent structures. Protective systems include supports, sloping and benching, shields and other means to protect workers.

5. Shoring

Hydraulic, timber or mechanical systems that support the sides of an excavation, designed to prevent cave-ins.

6. Hydraulic Shoring

A pre-engineered support system of aluminum hydraulic cylinders (cross-braces) used with vertical rods (uprights) or horizontal rods designed specifically to support side walls of an excavation to prevent cave-in.

7. Benching

A method of protecting employees from cave-ins by excavating the sides of an excavation to form one or a series of horizontal steps, with a vertical rise between steps.

8. Sloping

A method of excavating in which the sides of an excavation are laid back to a safe angle to prevent cave-ins. (The safe angle required varies with different types of soil, exposure to the elements and superimposed loads. There is no single angle of repose. Soil classification must be identified to select safe sloping and benching methods.)

9. Soil Classification System

A method of categorizing soil and rock deposits as types A, B, and C in decreasing order of stability. Soil type is determined by analysis of the soil's properties and how it performs under exposure to the elements and superimposed loads.

Type A:

Cohesive soils with an unconfined compressive strength of 1.5 ton per square foot (tc) (144kPa) or greater are classified as Type A. Examples of cohesive soils are: clay, silty clay, sandy clay, clay loam and in some cases, silty clay loam and sandy clay loam. Cemented soils such as caliche and hardpan are also considered Type A. However, no soil is Type A if one or more of the following conditions are true:

(i) The soil is fissured. (ii) The soil is subject to vibration from heavy traffic, pile driving, or similar

effects. (iii) The soil has been previously disturbed. (iv) The soil is part of a sloped, layered system where the layers dip into the

excavation on a slope of four horizontal to one vertical (4H:1V) or greater.


(v) The material is subject to other factors that would require it to be classified as a less stable material.

Type B:

Soils classified as Type B are: (i) Cohesive soils with an unconfined compressive strength greater than 0.5 tsf

(48 kPa) but less than 1.5 tsf (144 kPa). (ii) Granular cohesionless soils including angular gravel (similar to crushed

rock), silt, silt loam, sandy loam and, in some cases, silty clay loam and sandy loam clay.

(iii) Previously disturbed soils except those which would otherwise be classed as Type C soil.

(iv) Soil that meets the unconfined compressive strength or cementation requirements for Type A, but is fissured or subject to vibration.

(v) Dry rock that is not stable. (vi) Material that is part of a sloped, layered system where the layers dip into the

excavation on a slope less steep than four horizontal to one vertical (4H:1V) but only if the material would otherwise be classified as Type B.

Type C:

Soils classified as Type C are: (i) Cohesive soils with an unconfined compressive strength of 0.5 tsf (48 kPa)

or less. (ii) Granular soils including gravel, and loamy sand. (iii) Submerged soil or soil from which water is freely seeping. (iv) Submerged rock that is not stable. (v) Material in a sloped layered system where the layers dip into the excavation

or a slope of four horizontal to one vertical (4H:1V).

10. Trench Boxes:

A structure that is able to withstand the forces imposed on it by cave-ins, and in the process, protects employees inside the structure. (Plans for trench boxes are to be submitted to Loss Prevention.)


2.1 Before Work Starts

In order to begin excavation work with minimum risk to men, plant and equipment and to enable the work to proceed without interruption, the following factors must be considered well before the job starts:

1.) Size and purpose of the excavation. 2.) Nature of the ground including the proximity of made-up ground. 3.) Stability of adjacent structures. 4.) Position of underground obstructions such as pipes, electric cables, and other utilities. 5.) Weather and soil moisture conditions, especially high water table. 6.) Sources of soil vibrations (highway traffic, railroads, machinery, etc.). 7.) Adjacent roads and footpaths. 8.) Method of excavation. 9.) Excavation plan submitted to Loss Prevention.

Consideration of these factors will indicate the safety measures which must be implemented to proceed with the job and whether the sides of the excavation can be sloped and benched to a safe angle or whether other protective systems will be required. It is important to provide adequate and suitable protective systems for use whenever excavation work is to be carried out to a depth of 1.5 meters (5 feet) or more. Excavation work to a depth of less than 1.5 meters (5 feet) may also require protective systems.

2.2 Work Permit

Work permits must be obtained from the appropriate operations supervisor before excavation work is started in any Saudi Aramco facility, including residential areas and roadways, and in any place where the presence of underground/utility obstructions is known or suspected. Outside of clearly defined responsibility areas, work permits shall be obtained from the Superintendent, Utilities and the Communications Foreman, Oil and Gas Dispatch Unit or their delegated representatives. A Confined Space Entry Work Permit is a second work permit and is required for trenches deeper than 1.2 meters (4 feet). (See GI 2.100 for work permit requirements.)

All protective shoring systems and configurations, such as timber shoring, hydraulic and pneumatic systems, sloping, benching, shielding, sheet piling and freezing must be designed in accordance with Saudi Aramco Loss Prevention requirements. Excavation plans must be submitted to Loss Prevention before work start up.

2.2.1 Excavation near Saudi Telephone Cables

To avoid disruptions of service and unnecessary costs which result from the accidental cutting of Government telephone cables by contractors working on Saudi Aramco projects, proponents should urge their contractors to inquire about the location of such cables prior to excavation. Contractors may contact the Saudi Telephone Cable Locator Division on telephone no. 843-3247 during normal Government working hours or telephone no. 906 at any hour. Subsequently, they may be required to submit a written application to the Saudi Telephone Cable Locator Division providing a site plan of the proposed excavation and stating when it will be done. Contractor letters may be addressed to the Director, Dammam Area Communications, Ministry of Telegraph Post and Telephone, Dammam.


Saudi Aramco proponent inquiries may be addressed to the Contractor Liaison Division of Government Affairs, telephone 874-1461 (Corporate Advisor, Contractor Liaison/GAO).

2.3 Underground Obstructions

Whenever the presence of underground pipes, cables, vessels, or structures is known or suspected, mechanical excavators shall not be used until all such obstructions have been exposed by hand digging. Mechanical excavators shall not be used within 3 meters (10 feet) of any such obstruction. Pneumatic breakers shall only be used where necessary to break concrete or other hard surfaces.

2.4 General Precautions

2.4.1 Shoring Protective Systems

As soon as an excavation reaches a depth of 1.2 meters (4 feet) or soil banks are greater than 1.5 meters (5 feet), suitable shoring shall be installed or the sides sloped back to a safe angle. Shoring may be of timber or any other suitable material, such as steel sheet piling.

The determination of the angle of slopes, benches, (See Figure II.3) or the choice and design of other protective systems shall be based on evaluation of pertinent factors such as: type of soil (Type A, B, or C), depth of cut; possible variations in water content of the material while the excavation is open; anticipated changes in materials from exposure to air, sun, or water; loading imposed by structures, equipment, overlying material, or stored material; and vibrations from equipment, blasting, traffic, or other sources.

Excavations shall not be sloped at an angle greater than one and one-half horizontal to one vertical (340 measured from the horizontal). Plans for sloping and benching systems shall be sent to Loss Prevention for review. (See Figures II.3, II.4, II.5.)

Shoring systems shall be designed by a qualified person and meet accepted engineering requirements. Materials used shall be in good serviceable condition, and timbers shall be sound, free from large or loose knots, and of proper dimensions.

2.4.2 Personnel Protection

Portable trench boxes or sliding trench shields may be used for the protection of personnel in lieu of a shoring system or sloping. Where such trench boxes are used, the design shall be approved by Saudi Aramco Consulting Services Department.

Trench boxes shall be designed, constructed and maintained to provide protection equal to or greater than the sheeting or shoring required.

Shields shall be installed in a manner to restrict lateral or other movement of the shield and be capable of withstanding any sudden application of lateral loads.


Shields shall be extended above the excavation to protect employees working inside the shields and when entering or exiting the areas protected by shields.

Employees shall not be allowed inside the shielded areas whenever shields are being installed, removed or moved (see Figure II.7).

2.4.3 Inspection

All parts of an excavation, including the shoring, shall be inspected every day by a competent person to ensure that there is no danger of collapse and all observations shall be noted in the site safety log book.

2.4.4 Clearance

In order to provide a safe footing at the edge, and to prevent spoil falling into an excavation, a clear space at least 0.6 meter (2 feet) wide shall be maintained on all sides. (See Figure II.8: Guide to Safe Distance Back From Top Of Slope For Storage of Materials / Equipment Placing.)

2.4.5 Mechanical Excavator

Men shall not be permitted to work underneath loads or in places where they could be struck by any part of a mechanical excavator.

2.4.6 Walkways

Where employees, equipment, or members of the public are required or permitted to cross over an excavation, a close planked bridge or walkway with standard guard rails shall be provided and kept clear of excavated materials or other tripping hazards. No sidewalk shall be undermined unless properly shored.

2.5 Access and Egress

Safe means of getting into and out of an excavation shall be provided at intervals not exceeding 7.5 meters (25 feet). Ladders shall conform to the requirements set out in Section 9.2, be placed at an angle of 75o, and extend at least 0.9 meter (3 feet) above the stepping-off point. Ladders shall be securely fixed.

2.6 Hazardous Atmospheres and Materials

2.6.1 Ventilation

Where there is reason to suspect oxygen deficiency or the presence of a hazardous atmosphere in an excavation, gas tests must be carried out by a qualified person. Where necessary, mechanical ventilation shall be used, or other appropriate precautions shall be taken before men enter.

Note: Toxic, oxygen and flammable gas tests are to be conducted before entering hazardous excavations in Restricted Areas (as mentioned in GI 2.100).


2.6.1.1 Hazardous Atmospheres

Prior to entry into excavations greater than four feet deep, or confined spaces, a work permit shall be issued. Gas tests shall verify that the oxygen level is 20-21%, combustible gases 0.0 LEL, and H2S is 0 ppm. For elevated levels of gases tested follow requirements of GI 2.100. Corrective measurers may include use of air movers, identification and isolation of sources from fuel lines, sewers, open tanks or other measures to return the breathing atmosphere to normal readings. Subsequent testing is required to monitor the area during the work so appropriate precautions can be taken as necessary.

• Precautions shall be taken to prevent employee exposure to an atmosphere containing a concentration of any flammable gas above its lower explosive limit (LEL).

• For an atmosphere with a concentration of any flammable gas below its lower explosive limit (LEL), use the guidelines given in GI 2.100 (Work Permit System) as shown below:

• Above 0.0 LEL - No hot work permitted • 0.05 LEL to 0.5 LEL - Breathing apparatus must be used • Above 0.5 LEL - No entry permitted

• When controls are used that are intended to reduce the level of atmospheric contaminants to acceptable levels, testing shall be conducted as often as necessary to ensure that the atmosphere remains safe.

2.6.1.2 Emergency Rescue Equipment

(i) Emergency rescue equipment, such as breathing apparatus, a safety harness and line, or a basket stretcher, shall be readily available where hazardous atmospheric conditions exist or may develop during work in an excavation. This equipment shall be attended by a standby man outside the trench when in use.

(ii) Employees entering bell-bottom pier holes, or other similar deep and confined footing excavations, shall wear a harness with a lifeline attached to it. The lifeline shall be separate from any line used to handle materials, and shall be individually attended at all times while the employee wearing the lifeline is in the excavation. Mechanical devices shall be available to lift incapacitated employees from excavations.

2.6.2 Exhaust Gases

Where an internal combustion engine is used in an excavation, special precautions must be taken to ensure that exhaust gases are discharged so as not to be a hazard to men working in the excavation.


2.6.3 Organic Lead

Where the presence of buried organic lead (TEL) sludge, asbestos or any other hazardous chemical is known or suspected, whether in a Restricted Area or not, excavation work shall not be started (or continued) until the Industrial Hygiene Service and Loss Prevention Departments have identified the hazard and specified the precautions to be taken and a new work permit has been issued.

2.7 Edge Protection, Markers and Fixed Lighting

Whenever it is necessary to place or operate power shovels, derricks, trucks, materials, soil banks or other heavy objects on a level above and near an excavation, the side of the excavation shall be sheet-piled, shored, and braced as necessary to resist the extra pressure due to such superimposed loads. When mobile equipment is utilized or allowed adjacent to excavations, substantial stop logs or barricades shall be installed. If possible, the grade should be away from the excavation. If men or vehicles are in the vicinity after dark, fixed warning lights shall be used to mark the limits of the work.

2.8 Roads, Streets, and Sidewalks

Excavation work in roads, streets, and sidewalks shall not be undertaken without the prior approval of the relevant authorities (See Section II.1, Work Permit System). Excavation work on public highways will have to be cleared in advance with Government Affairs and any special measures that they might specify must be implemented (See Section II.8, Roadworks).

2.9 Backfilling

Backfilling and removal of trench supports shall be accomplished first by backfilling up to a level allowing for the removal of the lower braces. Another layer of backfill shall be positioned in the trench to the next layer of braces to be removed. Removal of trench supports shall progress together with the backfill from the bottom of the trench. In unstable soil, ropes shall be used to pull out the jacks or braces from above after employees have cleared the trench. All excavations shall be backfilled and consolidated, and the surface shall be left in good condition as soon as is practicable.

2.10 Borrow Pits

Location of borrow pit boundaries (i.e., residential, industrial plants, sub-stations, highways, etc.) shall be located at the distance noted in SAES-A-111.

2.10.1 A separate traffic flow plan is required to keep pedestrian traffic away from vehicle traffic areas. Traffic is strictly prohibited in borrow pit areas. Signs in Arabic and English shall be posted in roped-off areas, warning personnel to stay out of borrow pits.

2.10.2 Dust concentration, noise levels, and security fencing associated with borrow pit operations shall be in accordance with Saudi Aramco Safe Operating Procedures.


2.10.3 Hydraulic Shoring For Trenches

Hydraulic shoring is provided as a method of protection against cave-ins in trenches that do not exceed 20 feet (6.1 m) in depth. Trench depths exceeding 20 feet (6.1 m) require Loss Prevention review.

It is not intended that the aluminum hydraulic specifications apply to every situation that may be experienced in the field. These data were developed to apply to the situations that are most commonly experienced in current trenching practice. Situations that are not covered require specific designs for specific applications and will be subject to Loss Prevention review. (See Figures II.9, II.10, II.11, and II.12.)

2.10.4 Timber Shoring For Trenches

Timber shoring is provided as a method of protection from cave-ins in trenches that do not exceed 20 feet (6.1m) in depth. Loss Prevention requirements must be used when timber shoring protective systems are designed. (See Figures II.13, II.14, II.15 and II.16.)

3.0 DEMOLITION

Numerous factors must be taken into account before the method of demolition is decided. Of prime importance are the age of the structure, the method of construction, the state of preservation, its previous use, and the surrounding environment. These factors must be known before any planning can begin.

Many problems are peculiar to the demolition of tanks, vessels, and ancillary pipe work associated with the oil industry. For instance, many serious accidents have resulted when due consideration was not given to the cleaning and gas-freeing of this equipment before work began.

The contractor shall submit a Hazard Identification Plan as a part of his loss prevention program to the Company Representative. All such programs must be reviewed and concurred with by the Loss Prevention Department before start-up. (See Chapter I, Section 1.3.2.)

3.1.1 Responsible Supervisor

Before any demolition work is started, a competent supervisor must be appointed in writing as the person responsible for all work on site. The man appointed should be experienced in demolition operations. His duties will include the direct supervision of the work force, ensuring that work permit requirements are met, and liaison with other contractors working in the general area and with operators and construction or maintenance engineers.

3.1.2 Original Drawings

The original drawings of the structure to be demolished should be obtained. An examination of them should be made to ascertain whether any major changes from the original construction have been made and where utility connections may be found.

3.1.3 Disconnections

All utility services such as electricity, gas, and water must be shut off and the main supplies disconnected outside the line of the demolition work. Tanks, vessels, and paperwork must be completely disconnected from inlet, outlet, and overflow points.

3.1.4 Adjacent Structures and Publ ic Areas

Adjacent structures, public buildings, pedestrian walkways, parking lots, etc. shall be protected from demolition debris that can likely cause hazards to the general public. Also, bracing must be installed to insure stability of adjacent structures.

3.1.5 Barricades/Signs

Barricades must be erected around the work area. Signs bearing the words "Danger - Demolition in Progress" in Arabic and English must be erected at each approach to the barricade.

3.2 Method of Demolition

The method of demolition to be used should be decided upon in consultation with the Saudi Aramco representative, Loss Prevention and all contractors involved. The re-use of salvage materials should be considered prior to this decision. It should be remembered that the safest and most efficient method is to start at the top and dismantle in the reverse order of construction. There are, however, cases where such a method is impractical or uneconomical and where other methods have to be considered. Any portion of the job which contains asbestos insulation should be cleared under the general procedures (See Section II.4), and Industrial Hygiene Services, Preventive Medicine Services Division, shall be contacted.


3.2.1 Demolition of Equipment Containing PCB: Polychlorinated Biphenyl (ASKAREL)

Before equipment containing or suspected of containing PCB(s) is removed in demolition work, the Loss Prevention Department and the Industrial Hygiene Unit shall be notified to ensure safe procedures are used. Proper personnel protection equipment and disposal systems must be utilized. (See GI 355.004.)

3.2.2 Demolition Of Buildings With Asbestos / Insulation Materials

Before demolition of buildings with asbestos and insulation, notify Loss Prevention and Industrial Hygiene Services to ensure safe procedures are followed. Proper personnel protective equipment and disposal systems must be utilized. (See Chapter 4 and GI 150.001.)

3.3 Stability During Demolition

As work progresses, continuing inspections must be made to detect hazards arising through weakened or overloaded floors, unsupported walls, or loose material. Immediate steps shall be taken by bracing or by other means to prevent the premature collapse of the whole or any part of the structure.

3.3.1

Lateral support should not be removed from more than one story of wall at any time before starting to demolish it. When a wall from which support has been removed must be left standing at anytime, including overnight and off-shift work hours, adequate bracing (guying) must be provided to prevent collapse and to guard against wind pressures.

3.4 Working Place Clearance

3.4.1 Access

A safe means of access to and egress from all working places must be provided. Work places and the areas around ladders and stairways must be kept clear of material and debris.

3.4.2 Glass Removal

Nails in timber must be removed or bent over, or the timber must be stacked where it will not be a source of danger. All glass in windows, doors, partitions, etc. should be completely removed prior to structural demo lition.

3.5 Structural Steel Removal

All steel construction should be demolished column length by column length and tier by tier. A structural member being removed must not be under any stress other than its own weight. Members being cut or dismantled should be chained or lashed in place to prevent uncontrolled swinging or dropping.


3.6 Tanks, Vessels and Pipe Work (Explosion Prevention)

3.6.1 Welding and Hot Cutting

No tank, vessel, or pipe work which has contained explosive or flammable material shall be subjected to welding or hot cutting operation until all steps have been taken to remove the substance and any vapors. When hot cutting is planned, the advice of the area Fire Chief and the Loss Prevention Department should be sought.

3.6.2 Cold Cutting

The use of cold cutting techniques for the dismantling of tanks, vessels, and pipe work, can substantially reduce the risk of explosion. Although this is often more costly and laborious, there are times when it is the only safe method which can be used.

3.6.3 Steaming and Ventilation

In the case of vessels and tanks up to about 22,712 liters (6000 gallons) capacity, both vapors and residues can usually be removed by steaming out; however, with larger tanks the problems are somewhat different. Because of the high capacity of a large tank, steaming cannot be relied on to volatilize all residues unless very large quantities of steam are available. It is, however, relatively easy to eliminate explosive concentrations of vapor within the tank by forced ventilation using a blower or eductor system approved for hazardous locations.

3.6.4 Residue Cleaning

With volatile materials, use of such methods as in 3.6.3 above will rapidly reduce vapor concentrations. With materials less volatile, the main danger lies in the hot cutting setting fire to any residues in the tank. It is, therefore, essential that any residues are removed before work starts.

3.7 Protective Clothing and Equipment

All demolition workers should be provided with and make use of the following protective equipment:

1 Safety helmet 2 Goggles 3 Heavy duty gloves 4 Appropriate respiratory equipment (whenever necessary to prevent inhalation of dust

and fumes) 5 Safety boots with steel toe caps and preferably with penetrant resistant soles.

Safety belts or harnesses (with lifelines where required) shall be used by men working in isolated or dangerous locations where there is the possibility of them falling and where other preventive measures are impractical.


3.8 Mechanical Equipment Guards

Mechanical equipment such as cranes and bulldozers should be equipped with wire mesh guards over windows and with solid protection over the driving position so that there is no danger of the operator being struck by flying debris.

February 1993 - Construction Safety Manual: Asbestos And Other Fibers Page 158

4.0 ASBESTOS AND OTHER FIBERS

Asbestos is the generic name given to a number of naturally occurring inorganic fibrous silicate minerals. Asbestos materials have been widely used in the construction industry and may be present in a number of manufactured products such as cement sheeting, molded insulation, gaskets, ropes, blocks, fire resistant boards, etc. For the purpose of these regulations, asbestos is defined as any of the minerals crocidolite, amosite, chrysotile, fibrous anthophyllite or any mixture containing any of these minerals.

The use of asbestos is restricted. At present, the Saudi Aramco Industrial Hygiene Unit must approve the use of asbestos materials, under GI 150.001.





GI 150.001 Asbestos Regulations


ASTM C460-88

Standard Definitions of Terms Relating to Asbestos - Cement

4.1 Types of Asbestos

These exist in two main rock-forming mineral groups: 1) Serpentine group, which includes chrysotile (white asbestos); and, 2) Amphibole group, which includes crocidolite (blue asbestos) and amosite (brown asbestos). These two main groups were the most widely used asbestos minerals. However, fibrous anthophyllite has also been used in industry in a few applications. Chrysotile was commonly used as the reinforcing material in asbestos-cement products. Because crocidolite has high resistance to acids, it has been extensively used in chemical plants. Due to the superior heat resistance of amosite it has been used principally for the manufacture of fire-resistant insulation boards. The majority of asbestos products has been made of white asbestos, but some products contain blue asbestos (crocidolite). Of the asbestos products manufactured blue asbestos has the higher health risk. Blue asbestos can usually be recognized by its dark lavender blue color; however, its presence could be masked by other materials. Since prolonged exposure to heat, as would be the case with boiler or hot-pipe lagging, may change the characteristic blue color of crocidolite to a white or fawn color.

4.2 Health Risks

Over a period of time, breathing asbestos dust can cause asbestosis (scarring of the lung), which may go undetected for years after exposure. All forms of asbestos are capable of causing asbestosis. The most important factors in the development of the disease are the amount of dust to which the individual is exposed, duration of exposure, and the personal susceptibility of the individual to the asbestos fiber. In addition, asbestos fibers can

February 1993 - 4.0 Asbestos And Other Fibers Page 159

penetrate the skin, causing small tumors, warts, or corns. These asbestos tumors are usually found on the palms or fingers. They may not be cured unless every minute fiber is removed.

The maximum allowable concentration of airborne asbestos dust shall not exceed 0.2 asbestos fibers longer than five microns in length per cc of air on a time-weighted average (TWA) exposure for an eight-hour work day.


The contractor shall submit a Hazard Identification Plan to Loss Prevention Department and to the Industrial Hygiene Service, Preventive Medicine Services Division for review and concurrence prior to job start-up, when removing or using asbestos materials. (See Administration I, Section 1.3.4.) Unless approved of in advance by the Industrial Hygiene Unit, asbestos products shall not be used in new construction.

4.3.1 Air Sampling

Where the contractor knows that some part of an operation requires the use or removal of asbestos materials, he must notify, in writing, the Industrial Hygiene Services, Preventive Medicine Services Division. When informed, the Industrial Hygiene Services will take random samples of air at the point of operation during the working period. Bulk samples may be sent for the analysis and identification of asbestos to either Industrial Hygiene Services or to the Laboratories Department.

4.3.2 Job Details

The contractor shall then inform the Industrial Hygiene Services of details of the work involved, the number of persons employed, the anticipated duration of the operation, the type of asbestos being used, and the type of equipment being used to work the asbestos material.

4.3.3 Chest X-rays

It is the contractor's duty to ensure that each man employed on asbestos work be given a chest X-ray prior to commencement of the job and thereafter at two-year intervals. Detailed records shall be kept by the contractor of all persons employed in the process. These records shall be available to Saudi Aramco upon request.

4.4 Storage and Transportation

All asbestos materials removed from or used on a job shall be stored in an approved container at all times. For new construction, only that amount of asbestos material that is immediately required for the operation shall be moved to the work area.

Approved containers shall be used during the transportation of asbestos materials. All such containers that contain asbestos shall be clearly marked in English and Arabic: "Caution: Health Hazard - Contains Asbestos".


4.5 Work Area

The work area shall be clearly defined and where feasible roped off and notices displayed warning persons of the presence of asbestos dust. Signs shall be posted at all approaches to the work area. These signs shall be posted at readily visible locations near work areas and these notices shall read in both English and Arabic:

Caution:

ASBESTOS HEALTH HAZARD Respirator and protective overalls must be worn when entering this area.

Only persons directly concerned with the operation shall be permitted inside the area.

4.6 Handling and Use

4.6.1 Wetting/Ventilation

The handling, mixing, applying, removing, cutting, and spraying of asbestos materials shall be done in a wet state so as to prevent the emission of harmful fibers in excess of allowable concentration.

Before removing asbestos cement mortar, coating, grouting, plaster, or similar material containing asbestos from bags, cartons, or shipping containers, the material shall be wetted or enclosed, or the operation shall be carried out under total exhaust ventilation.

Work practices for using or removing asbestos are given in Section 4, GI 150.001.

4.6.2 Cutting

Shearing or punching shall be used in preference to sawing or drilling of asbestos. Where it is necessary to cut or saw materials containing asbestos using hand or power tools, it shall be done in a separate cordoned off area with an approved exhaust and dust collection system.

4.6.3 Protective Equipment

Protective equipment shall be required for all instances where asbestos is used regardless of ventilation, wetting, etc.

4.7 Protective Clothing

4.7.1 Types

The contractor shall provide approved disposable overalls, head covering, foot protection, and gloves to prevent any airborne asbestos fibers from coming into contact with the body.


The contractor shall provide a sufficient amount of clothing to each employee working with asbestos to ensure that a complete change of clean protective clothing is available for the start of each shift.

4.7.2 Contamination

At the end of each shift, contaminated personal protective equipment shall be collected and disposed of in accordance to GI 150.001. Under no conditions shall contaminated clothing be worn from the work site. Employees shall be careful to prevent contamination of street clothes from work clothes.

Asbestos-contaminated clothes shall be packed and carried in sealed impermeable bags or containers and disposed of in accordance to Section 6, GI 150.001.

4.7.3 Review

The Loss Prevention Department and Industrial Hygiene Services shall review the types and applications of contractor's protective clothing for its' acceptability to Saudi Aramco.

4.8 Respiratory Equipment

Where there is an unavoidable emission of asbestos dust, the contractor shall supply a respirator approved by Industrial Hygiene Services and Loss Prevention Department to each employee.

4.8.1 Type

In normal circumstances, an approved filter type dust respirator will be adequate protection; however, dusty jobs (e.g. stripping, delogging, demolition, etc.) involving asbestos materials require air-supplied positive pressure respiratory equipment.

4.8.2 Use

All employees shall be properly trained in the use of respiratory equipment before being engaged in any work with asbestos. Also, it is the contractor's responsibility to make sure that each worker be supplied with equipment that provides the level of protection required and of the proper fit.

4.8.3 Care

All respiratory equipment shall be thoroughly checked, cleaned, disinfected and stored at the end of each work period and before use by other persons.

4.9 Washing and Changing Facilities

The contractor shall provide showering/washing facilities for all employees engaged in asbestos work.


The contractor must ensure that employees use these facilities before leaving the job site at the end of each shift.

The contractor shall provide suitable changing accommodations, disposal facilities for protective clothing worn during asbestos work and separate accommodations for street clothing not worn during working hours.

4.10 Disposal of Waste Asbestos Materials/Clothing

All waste asbestos materials and disposal clothing shall be disposed of in sealed impermeable bags or containers.

All bags and containers shall be marked in both English and Arabic: "Caution: Health Hazard - Contains Asbestos". The bags and containers shall be handled and disposed of in accordance to Section 6, GI 150.001.

4.11 Cleanliness of Work Areas and Equipment

The contractor shall ensure that all machinery, equipment, work areas, and adjacent areas are kept free from asbestos dust and waste as provided in Section 5, GI 150.001.

February 1993 - Construction Safety Manual: Welding, Cutting, And Brazing Page 163

5.0 WELDING, CUTTING, AND BRAZING

This section outlines the principles involved and the precautions to be taken in gas welding, cutting, and brazing and electric arc welding operations.

Welding/cutting are safe operations if carried out in the correct manner. Where equipment is defective or there is no well-arranged, well-lit, or properly ventilated working place, hazards can arise.

ANSI Z49.1 Safety In Welding and Cutting

ANSI Z87.1 Practice For Occupational And Educational Eye And Face Protection

NFPA 70 National Electrical Code

5.1 Gas Welding: Oxy-Acetylene Equipment and Use

Personnel working with welding equipment shall be trained, competent, and provided with personal protection equipment. Welding goggles, helmets, screens, forced ventilation and similar equipment shall be provided to all workers and to trainees in the immediate area.

5.1.1 Gases

Oxygen (O2) is odorless. It can promote rapid combustion, therefore, grease and oil must never be used near oxygen as this could cause fire.

February 1993 - 5.0 Welding, Cutting, And Brazing Page 164

Oxygen cylinders or apparatus shall not be handled with oily hands or gloves. A jet of oxygen must never be permitted to strike an oily surface, greasy clothes or enter fuel, oil or other storage tanks.

Acetylene (C2H2) has a distinct odor often likened to that of garlic or sour apples. It is combustible when mixed with air over a wide range (2.5% - 81%). Acetylene burned with oxygen can produce a higher flame temperature than any other commercial gas.

Acetylene becomes unstable at pressures above 103 kPa (15 psig) which means it may explode. Under no conditions shall acetylene be generated, piped (except in approved cylinder manifolds) or utilized at a pressure in excess of 15 psi gauge pressure. Inside the cylinder, acetylene is dissolved in acetone to prevent internal explosion; therefore, it is essential that acetylene cylinders be stored, handled, and used in the vertical position to prevent the liquid acetone from escaping and damaging the valves and other equipment.

Warning: Regulated Acetylene pressures must never be allowed to exceed 103 kPa (15 psig) or it may explode.

5.1.2 Color Coding of Cylinders

Color coding can be of great help but also a potential source of danger as there is no internationally recognized standard color code. Refer to GI 355.020-4, Control of Compressed Gas Cylinders, for Saudi Aramco color coding requirements.

5.1.3 Storage Of Cylinders

5.1.3.1

Cylinders should be stored in a safe, dry, well-ventilated place prepared and reserved for that purpose. Flammable substances such as oil and volatile liquids or corrosive substances should not be stored in the same area. Oxygen cylinders and flammable gas cylinders shall be stored separately, at least 6.6 meters (20 feet) apart or separated by a fire proof, 1.6 meters (5 feet) high partition.

All storage areas shall have Arabic and English "No Smoking Permitted" signs prominently displayed.

All cylinders should be chained or otherwise secured in an upright position. To prevent rusting, cylinders stored in the open should be protected from ground contact, extremes of weather, or contact with water. Valve caps shall be kept in place when cylinders are not in use. Flammable substances shall not be stored within 50 feet of cylinder storage areas. (See GI 355.020.)

5.1.3.2

Cylinders shall not be stored at temperatures exceeding 54oC (130oF). Accordingly, they should not be stored near sources of heat such as radiators, furnaces, or near highly flammable substances like gasoline.


Cylinders shall be stored out of the direct rays of the sun, in protective enclosures or sun shelters.

5.1.3.3

Cylinder storage should be planned so that cylinders will be used in the order in which they are received from the supplier. Empty and full cylinders must be stored separately with empty cylinders plainly marked as such, to avoid confusion. Empty cylinders should be segregated according to the type of gas they have held.

5.1.3.4

All cylinder storage rooms shall be ventilated sufficiently so that explosive concentrations of gas cannot accumulate. Smoking or any other source of ignition shall be prohibited near storage areas, and appropriately marked "No Smoking" as in Section 5.1.3.1 above. All wiring shall be in conduit and electric switches shall be located outside the room. All electrical installations shall meet the National Electrical Code (NFPA 70) for hazardous areas.

5.1.4 Handling of Cylinders

Serious accidents may result from the misuse, abuse, or mishandling of cylinders.

5.1.4.1

Cylinders should never be lifted by their valves since the valves are not designed to take such stress. When the cylinder is not in use, the valve shall be protected with the valve cap.

5.1.4.2

All valves must be fully closed before a cylinder is moved. Unless a trolley or special carrier is used, regulators and hoses should be detached from the cylinders, for moving.


5.1.4.3

If cylinders are to be lifted by a crane, specially designed bottle holders with lifting eyes should be used. Chain and wire rope slings can allow cylinders to slip. Where a trolley is to be used for slinging, its base should be strong enough to take the weight of the cylinders. Do not lift a cylinder with an electromagnet.

5.1.4.4

Cylinders in transit on vehicles shall have valve caps in place and be firmly secured to prevent movement. Cylinders shall be secured to avoid any violent contact. Loading and unloading shall take place carefully. Cylinders shall not be dropped, thrown, dragged, used as rollers, or as a support. No damaged or defective cylinder shall be used.

5.1.4.5

When in doubt as to the proper handling of a compressed gas cylinder or its contents, the supplier of the gas, the Bottled Gas Coordinator (Central Area Storehouse Department), or Loss Prevention Department should be consulted. Depleted cylinders shall be returned to the supplier with the valves closed and the valve protection caps in place. Cylinders, even those marked empty, should be treated as a possible hazard and handled with great care as they still contain some gas.

5.1.5 Inspecting Equipment

All equipment should be examined immediately before use and regularly maintained. All welding operations shall be conducted in well ventilated areas.

5.1.5.1

Only soapy water should be used to check for leaks. Presence of a leak is often indicated by a hissing sound or unusual changes in the torch flame. Cylinders and valves should be kept clean. Valve sockets shall be kept free of grit, dirt, grease or oil.


5.1.5.2

Hoses should be used for one type of gas only and color coded for identification. They should be examined before use for any signs of splitting which might give rise to leakage. All connections should be made by clips or crimps. The hoses used for acetylene and for oxy gen shall not be interchangeable.

5.1.5.3

Connections and check valves should be regularly examined. Equipment should be fitted with the correct pressure regulators and a regular check should be made to ensure that the regulator is working properly. The torch nozzle should be kept closed.

An acetylene cylinder valve wrench shall be available at all times for the cylinder in use.

5.1.5.4

Means of torch ignition should be readily available. A friction lighter shall be used for this purpose.

5.1.5.5

Acetylene can form explosive compounds in contact with certain metals or alloys, particularly unalloyed copper or silver. Joint fittings or lines made of copper should not be used and acetylene should not be allowed to come into contact with copper pipe work or tubing. Only approved materials shall be used for acetylene systems.

5.1.5.6

It is dangerous to let the torch flame come into contact with gas cylinders or for the lighted torch itself to be left unattended. Torches shall never be sat down while lit. It is equally dangerous to rest blowpipes, even extinguished ones, on old drums. "Empty" drums which have contained low flash point liquids are known to have become lethal bombs when a hot welding torch was laid down on them.

5.1.5.7

Cylinders in use should be kept upright on a custom-built stand fitted with a bracket to accommodate the hoses and equipment or otherwise secured. The metal cap should be kept in place to protect the valve when the cylinder is not connected for use.

5.1.6 Faults

It is not uncommon for minor "explosions" to occur during welding or cutting. Most are more frightening than harmful, but some can lead to very dangerous conditions.


There are four general groupings of these faults:

1 Snapout can occur during use when: • Both regulators are set at an incorrect pressure • Torch nozzle obstructed • Nozzle held too close to the work

Corrective action: • Completely shut both torch valves • Check regulator setting • Check cylinder pressures • Check nozzles • Re-light • Ensure adequate gas flow

2 Backfire can occur on lighting up when: • Regulators not set to correct pressure • Light applied before flow of gas mixture properly established

Corrective action: • Close both torch valves, oxygen first • Check cylinder pressures • Check and adjust regulator settings • Cool torch and check nozzle orifice for obstruction • Re-light

3 A flashback is very dangerous. Flashback is caused by gases being mixed in the hose(s). Usually this mixing of gases occurs when the hoses have been disconnected from regulators or torches or when a new hose is being used for the first time. Sometimes it is due to loose connections. Usually one of the hoses will have burst and possibly ignited.

Preventive action: • Use flashback flame arrestors for regulator and torch • Ensure all connections are tight • Ensure cylinder valves are open and torch valves closed • Set regulators to the required pressures • Purge each hose separately and consecutively by opening the

torch valve and allowing gas to flow for sufficient time to ensure only pure gas remains in the hoses

• Close the valve for each gas as the purge is completed • This purge should be carried out only in the open or in extremely

well-ventilated areas

Corrective action: • Close both torch valves


• Close both cylinder valves • Extinguish hose if alight • Repair equipment and hoses

5.1.7 Fuel Gas and Oxygen Manifolds

Fuel gas and oxygen manifolds shall bear the name of the substance they contain in English and Arabic letters at least 1-inch high which shall be either painted on the manifold or on a sign permanently attached to it.

Fuel gas and oxygen manifolds shall be placed in safe, well ventilated, and accessible locations. They shall not be located within enclosed spaces.

Manifold hose connections, including both ends of the supply hose that lead to the manifold, shall be such that the hose cannot be interchanged between fuel gas and oxygen manifolds and supply header connections. Adapters shall not be used to permit the interchange of hose. Hose connections shall be kept free of grease and oil.

When not in use, manifold and header hose connections shall be capped.

Nothing shall be placed on top of a manifold, when in use, which will damage the manifold or interfere with the quick closing of the valves.

5.2 Electric Arc Welding

Arc welding is a process for joining metals by heating with an electric arc. For arc welding, two welding leads, the electrode lead and the work lead, are required.

5.2.1 Voltage

The voltage across the welding arc is normally within the range 20-40V. The voltage supplied, however, needs to be somewhat higher so that means of stabilizing and regulating the arc current can be introduced into the circuit. Using DC, a 60-80V supply will usually suffice. Using AC, an 80-85V supply will suffice although some of the latest techniques need an open circuit voltage of up to 100V between electrode and work. It should be remembered that a nominal 100V supply has, in fact, a peak voltage of 141V.

For these reasons, DC should be used for welding operations in any situation where the effect of electric shock is likely to be extreme, such as in damp and confined spaces (tanks, boilers, etc.).

5.2.2 Welding Connections

In each welding circuit there are three main connections:

1) the welding lead; 2) the welding return; 3) the welding ground.

5.2.2.1


The welding lead is the conductor carrying the welding current from the point of supply to the electrode holder.

5.2.2.2

The welding return is the conductor carrying the current back from the work to the point of supply. Its conductivity should at least equal that of the welding lead. The welding return should be used to ground the metal case of the welding machine. This high current capacity is essential, because all the current fed to the arc has to be conducted back to the supply point. The current involved could be as high as 300 amperes on a hand welding operation.

5.2.2.3

A continuous welding ground is essential and indispensable for conductors since electric currents as low as 50 milliamperes can be fatal. The ground should be of low impedance so that there can be no rise in the potential of the work and so that sufficient fault current passes quickly enough to cut off the supply if necessary. It is recommended that the welding ground be bonded to the ground of the main supply system by a separate substantial conductor.

The frames of all fixed arc welding and cutting machines shall be grounded either through a third wire in the cable containing the circuit conductor or through a separate wire which is grounded at the source of the current.

Welding grounds and returns should be securely attached to the work by cable lugs, by clamps in the case of stranded conductors, or by bolts for strip conductors. Bolts are unsatisfactory for stranded conductors, since the strands can loosen under the bolt head and become detached (see Manufacturers Grounding Specifications for Electrically Powered Equipment and Engine Powered Equipment).

5.2.2.4

Welding cable insulation needs to be abrasion resistant to withstand normal treatment over rough ground and the wear inflicted by foot and vehicular traffic. Where feasible, cables should be additionally protected by stringing overhead or by using cable covers. They should be regularly examined for cuts or abrasions to the insulation; damaged cable shall not be used. If joints become necessary, standard plug and socket coupling shall be used. Holders should be unplugged when not in use. If joints become necessary, standard plug and socket couplings shall be used. Splices are not allowed in welding cables.

5.2.2.5

Electrode holders shall be constructed to accommodate all sizes of electrodes and with an ejector for hot, spent stubs.


5.2.2.6

A shield should be fitted between electrode holder and handle to prevent live elements from being touched. The handle itself shall be made of non-flammable insulating material and be free from joints or holes.

5.2.2.7 Auxiliary Power Outlets

Most welding machines are furnished with an alternator which produces 3 KVA of 115 and 230 volts. As a safety factor, all power hand tools which are not double insulated should be grounded to the welder frame. Ground Fault Interrupters are required, where power output exceeds 5 KV. Placards must be placed on the welding machine.

5.3 Protective Measures

5.3.1

The need for the operator to take safety precautions and preventive measures during the operation of welding machines to ensure that no safety-related incident occurs cannot be overemphasized. The following is a list of precautions and operating considerations to take into account when operating a 400 amp arc welding machine, for example. All users are strongly encouraged to read the equipment's operating manual to ensure reliable and safe operation.

1. Keep all doors, covers and panels in place when operating the machine: the arc welding machine is designed to operate with all its doors, covers and panels in place. They ensure the optimum flow of cooling air, and removal of these covers and panels will reduce the cooling of the engine and generator, resulting in overheating and premature failure of the unit.

2. Ensure that the engine protection push button 'pops out' when the engine is switched off. Under normal circumstances, this button will 'pop out' once the engine is switched off. However, if the unit becomes clogged with dirt, dust or sand, it may not return to its 'off' position without assistance. If the button remains depressed, it will quickly drain the unit's battery. The resulting failure to start will delay your work while a new battery is fitted, a 'jump start' arranged, or a recharge cycle is completed.

3. Maintain welding and ground cables and connections in good condition. A major source of safety hazards, poor and inconsistent welding performance, and loss of point-of-use welder capacity is a set of welder leads in poor condition, or of the wrong size for the length of cable being run. Other sources of safety hazards related to cables and connections are:

• cracked insulation is an obvious source of hazard producing shorts to ground eventually leading to increase of conductor resistance. With no-load voltages approaching 100+ volts, significant hazard of electrocution to personnel exists, especially in wet areas or when working on metal structures.


• combining sets of low capacity cables to reach a distant welding site can greatly reduce the effective welding power available to the welding machine. Larger-capacity cables must be used to reach distant sites, because of the buildup of resistance from the extra length of the leads. Inadequate or weak cable connections can also introduce sparking hazards, potential shorts to ground, and extra resistance which reduces effective welding machine capacity. Cable sizes and lengths must be as recommended by the manufacturer, as follows (for 400 amp machine):

Combined length of electrode and

work cable Minimum Cable Size

up to 150 feet 2/0 150-200 feet 3/0 200-250 feet 4/0

4. When welding is in progress, the full length of cable must be stretched out on the ground. Leaving the cable coiled on the machine alters the current flow and disrupts the welding process.

5. Do not adjust the 'current control' while welding is in progress. This can damage the control.

5.3.2

Sparks and molten or hot metal coming from the work area can easily set fire to combustible materials near or below the working area. Wherever possible, all combustible material should be removed from the work area. If it cannot be removed, it should be covered with fireproof material. Gas cylinders should be protected from falling sparks.

5.3.3

Operators of arc welding equipment must always switch off the current to the electrode holder and remove the electrode whenever it is to be set down and is not actually in use.

5.3.4

When welding or cutting material that is supported by a crane, a shield or an effective screen should be provided to protect the suspension ropes or chains. Grounding cables shall only be connected to the work, not to the crane or rigging.

5.3.5

Forced ventilation shall be arranged wherever work is to be carried out in a confined area. Suitable metal bins shall be provided for spent electrode stubs as they are usually hot when discarded and can easily cause a fire. Dry chemical fire extinguishers should be kept available while work is in progress. All completed work should be marked "HOT".


5.4 Welding and Cutting: Tanks, Vessels and Drums

Careful tests should be made to establish that the tank, vessel or drum is free from explosive flammable vapors or substances. The responsible supervisor should make a check before permitting any work to begin. It is essential that past contents of the tank, vessel or drum be identified. If there is any doubt or if the tank is known to have had any kind of flammable or explosive content, it should be cleaned and purged thoroughly prior to welding or cutting. Extreme care should be taken in considering methods of tank welding and cutting as these jobs are hazardous operations unless correct safety measures are taken. (See General And Civil II.1, Work Permit System.) Welding and cutting on drums is strictly controlled and, in most cases, prohibited. Contact area Loss Prevention for guidance and information.

Note: The use of oxygen for blowing out containers and small tanks is forbidden.

5.5 Confined Spaces

It is vital that forced ventilation be maintained in confined spaces at all times. Air line respirators may be needed for men working inside such places. No gas cylinders should ever be allowed into such an area. The hoses and equipment used inside must be in excellent condition.

Where work in confined spaces has to take place over several days, the hoses and equipment shall be taken outside overnight in case of any leakage that could occur, resulting in a build up of gas. (See General And Civil II.1, Work Permit System. )

5.6 Personnel Protection

5.6.1

Helmets, welding hoods, and goggles are necessary to protect eyes and face against heat and the effect of the intense light emitted by welding operations.

5.6.2

Goggles are required to protect the eyes of the welder from pieces of flying slag chips during electric arc welding. They should be fitted with opaque side pieces. These goggles should also be worn under the regular welding hoods.

5.6.3

Electric welding operations must be effectively screened to prevent nearby personnel from being affected by harmful radiation. Screens should be made from fire resistant materials or should be suitably treated with a fire resistant compound. Screens should be designed and placed so as not to restrict the flow of air for ventilation purposes.

5.6.4


Gloves are necessary protection to the hands against heat, sparks, molten metal, and radiation. Leather, suitably reinforced at points of maximum wear, is the material most generally worn. Gloves should be long enough to protect wrists and forearms. When gloves are not long enough, protective sleeves of similar materials should be worn.

5.6.5

Safety boots and leggings are essential to provide effective protection against heat, flying sparks, and falling metal. Pant cuffs shall never be worn inside of the safety boot.

5.7 Health Hazards

Apart from the obvious hazards of physical burns, health hazards in welding operations fall into two classes: hazards from radiant energy and hazards from dusts and fumes.

5.7.1 Radiant Energy

The process of welding produces radiant energy in the form of visible light, ultra-violet rays, and infrared rays. The risk of this energy harming the operator or other personnel can be minimized by the proper use of protective clothing and shielding. Exposure of the skin to infrared and ultraviolet rays can result in irritation and burning. The risk of exposure is lessened by wearing protective clothing, shielding, and distance.

Arc-eye or flash burn is a well known condition in welding operations and is due to the eyes being exposed to ultraviolet rays. This condition is a superficial burn on the outer layer of the eye.

The effects normally wear off within two days, and generally no permanent damage is caused. The condition is, however, extremely painful and can easily be avoided by the use of eye protective lens or shields.

Welding protective lens shall be tempered glass. Lens shall be distinctively marked to identify approved lens shade.

Lens Shade Guide: 1. Arc Welding- 10 to 14 2. Torch Brazing- 3 to 6 3. Gas Welding- 4 to 8

5.7.2 Respiratory Effects

The risk of being gassed in normal welding operations is slight; however, when working in confined areas, a forced ventilation system should be in operation to remove any build up of hazardous gases.

5.7.2.1

Oxy-acetylene welding operations can cause the oxygen and nitrogen of the air to unite to form nitrogen oxides. In well ventilated areas this


does not cause any problems; however, in confined areas or where the welder is working very close to the job, the amount of nitrogen oxides breathed can rapidly reach toxic levels. The main problem with this gas is that the welder does not appear to be affected at the time; the real effects take place some 6 to 24 hours after exposure.

5.7.2.2

All welding operations produce quantities of ozone, a highly toxic gas. In oxy-acetylene and electric arc welding, the amount produced is small and providing adequate ventilation is used, the risk is negligible. Significant and sometimes dangerous amounts of ozone can be formed when inert gas shielded welding is being carried out.

There are many other dangers which can arise when welding or cutting under specific conditions or on particular metals. Hazardous operations include: welding on manganese steel, galvanized material, material which has been degreased or on material which has been painted with lead, copper-bearing, or chromate-containing paint. These problems must be recognized before the job starts, and safe practices for dealing with them must be established.

Although welding cannot be regarded in general as an extremely hazardous occupation, exposure to concentrated fumes may be irritating and in some cases dangerous. It is essential that each operation be analyzed before work starts and that the control measures are correctly applied.

February 1993 - Construction Safety Manual: Explosive Materials Page 176

6.0 EXPLOSIVE MATERIALS

The use of explosive materials within construction is extensive and, whether large or small quantities are handled, the responsibilities falling upon supervisory staff are considerable. Those responsible must consider the acquisition, storage, transporting, handling and use of explosive materials, as well as the emergency procedures to be adopted in the case of misfire, accident, fire, etc. The acquisition and use of explosive materials in Saudi Arabia are strictly controlled by the Saudi Arab Government, whose requirements must be adhered to at all times. All blasting operations in Saudi Aramco are strictly controlled and the use of explosive materials by contractors is prohibited without prior written approval by Company representatives. For contractor In-Kingdom blasting operations, contact the Resources Planning Department, Project Support Services Division, Blasting Services Unit for all blasting requirements.

7.0 PILING OPERATIONS

Piling operations attract many of the problems associated with other types of construction work: access, unguarded machinery, housekeeping, etc. Heavy equipment and the stress and vibration imposed upon that equipment give rise to hazards peculiar to piling operations. The standard of supervision should be high, as well as the standard and maintenance of equipment.

Piling operations fall into two categories: driving load-bearing piles, which may be driven vertically or raked; and, driving sheet piles. Piles may be of steel, concrete, timber or any combination of the three. Piling equipment can vary from a simp le air-operated hand-held hammer to a large complex rig.

ASME Standard:

Section I Power Boilers Section VII Pressure Vessels


In order that piling operations may be undertaken with the minimum risk to men and equipment, the following factors should be considered before work starts.

• The nature and purpose of the operation.

• Soil investigation reports of the area.

February 1993 - 7.0 Piliing Operations Page 178

• Location and nature of any underground services in the area, which should be checked with the various departments through the Saudi Aramco Construction Engineer; then, precisely located by careful hand digging, under competent supervision.

Where piling operations are within a restricted area, the proper Work Permits should be obtained before any work is undertaken.

Competent supervision, experienced in piling operations, is essential for piling work.

Equipment of adequate capacity to perform the operation should be assembled. All equipment must be carefully inspected before being used with particular attention to the following. (See GI 7.030.)

7.1.1 Cranes

Cranes used for both lifting and piling operations should be of an adequate size and capacity to perform the work safely. Where cranes are to be used for driving raking piles with a drop hammer or driving piles below the level of the crane using extended leaders, the hammer will be suspended from the crane at a greater radius than the boom angle indicator will show. In all such cases, the distance of the hammer from the center point of the crane must be calculated and this distance used to ascertain the safe working load.

Outriggers, counterbalances, etc., shall be provided to maintain stability of the pile driver rig.

7.1.2 Pile Gates

Sufficient timber or steel must be available for the construction of pile gates. Proper ladder access must be provided to the pile gates, and where they are over 1.8 meters (6 feet) high, handrails or rigger's belts must be provided.

7.1.3 Inspection

Air compressors or steam boilers must be carefully examined and all hoses and couplings checked both for leaks and general condition. All steam and air hoses should be fitted with a regulator valve and a quick acting shut-off valve for emergency.

7.1.4 Wedges

An adequate supply of hardwood wedges should be obtained for adjusting piles while pitching. Softwood wedges are likely to split and must not be used.

7.1.5 Timber Block

Stop blocks shall be provided for the leads to prevent the hammer from being raised against the head block.

Guards shall be provided across the top of the head block to prevent the cable from jumping out of the sheaves.


Fixed leads shall be provided with ladder and adequate attachment points so that the loft worker may engage his safety belt lanyard to the leads. If loft platforms are provided, they shall be protected with standard guardrails.

Steam/air hose leading to the hammer or jet pipe and all hoses shall be securely attached with 1/4" chain or cable to prevent whip lash.

7.1.6 Ground Support

The ground upon which the crane or rig will stand should be firm and level. Digger mats or a hard-core standing should be provided if the ground is likely to subside under the high ground loading imposed by driving or extracting piles.

7.2 Driving Piles

7.2.1 Pitching

Piles should only be lifted and positioned in the pile gate or onto the leaders or rig with sound lifting gear adequate for the purpose. Quick release shackles should be examined before each use. Where hollow section or concrete piles are lifted with chains or wire slings, timber or burlap packing should be placed between the lifting gear and the pile. Adequate access, such as a cradle or a properly secured ladder, must be provided for the topman when pitching sheet piles. The topman must wear stout gloves when pitching.

7.2.2 Driving

Workmen should stand clear of the operation while driving is in progress. The emergency shut-off valve and the crane or winch controls must be manned at all times during driving. The foreman must be present and so positioned that he can be seen by the crane or winch operator and the man standing by the valve. When driving raking piles, the pile, leaders, and machine must all be in the same line. Under no circumstances should any man touch the hammer until all valves are closed. A system of signals must be arranged between the foreman, the winch or crane operator, and the valve operator, so that the emergency shutdown does not depend on verbal communication. Where the head of a pile becomes distorted through driving, no attempt should be made to clear it from the leaders by lifting or booming up. The pile head should be cut off and the debris cleared from the leaders.

7.3 Pile Extraction

No attempt should be made to extract piles which have been hammer-driven by lifting or booming up with a crane. A steam, air, or electric operated extractor should be used. Particular attention should be paid to the extractor wedges and the condition of the gripping faces, which should not be smooth. Workmen must not walk under piles that are suspended from extractors.


7.4 General Precautions

7.4.1

Men handling piles or working on piling operations should always wear safety helmets, safety shoes, safety glasses, stout gloves, and be equipped with ear protection, preferably of the muff type.

7.4.2

At the start of each shift, hammers and extractors should be carefully checked for loose bolts, etc.

7.4.3

All other equipment should be inspected daily for defects.

7.4.4

Piling operations should never be undertaken except under competent supervision and with a crew experienced in this class of work. Crane operators shall have a valid Saudi Arab Government heavy equipment license and a valid Saudi Aramco certificate (See GI 7.030).

7.4.5

Piling operations are a construction process with special hazards. In addition to these special hazards, men are exposed to the hazards commonly associated with all types of construction work, and precautions against these general hazards must not be neglected.

February 1993 - Construction Safety Manual: Roadworks Page 181

8.0 ROADWORKS

A contractor engaged in roadwork is not only responsible for the safety of his own men, he also has an obligation to protect the public from potential construction hazards, during the day, at night and in all weather conditions. Consequently, the marking of construction sites and the safe and efficient diversion and control of traffic must be properly planned and executed. Road closure plans must be submitted to Loss Prevention before roads are closed.

Failure to do this can have disastrous results.



GI 1021.000 Street and Road Construction, Excavation, and Maintenance of Traffic Controls (Appendix D)


8.1 General

8.1.1

Saudi Aramco organizations can obtain barriers, lights, etc. from the Maintenance Department during normal working hours. Contractors shall provide their own barriers, lights, etc..

8.1.2

To avoid creating a traffic hazard, warning devices must not be put in place until they are needed. They must be promptly removed when work is complete.

8.1.3

Activities which produce dust shall be kept to a minimum.

8.1.4

Permanent road signs and striping shall be restored before the roadway is returned to service.

8.1.5

The surface of any highway, street, or sidewalk shall be level and in good condition before any barriers and markers are removed.

8.1.6

Should there be any doubt as to the type of marking and protection required for roadwork in any location, the Loss Prevention engineer for the area should be consulted.

February 1993 - 8.0 Roadworks Page 182

8.1.7

A flagman, equipped with a safety vest and a red flag, shall be posted at least 50 meters (165 feet) from the work site at the entrance barricade and another flagman at the exit barricade. It shall be the duty of the flagmen to control the flow of traffic in a safe manner. Both flagmen shall be in sight of each other. If conditions do not permit this, then a third man shall be positioned where he can see and be seen by the other two men in order to signal them to start or stop traffic. Traffic control signals shall be in accordance with GI 1021.000. At night, flagmen shall wear light-reflecting vests and gloves, and use reflective signs or flags. Flagmen shall be stationed in an illuminated area.

8.1.8

During darkness, the work area will be marked by lights spaced 10 meters (30 feet) apart. Warning lights used in oil operations, industrial, or company housing areas shall be weather proof and positioned 0.6 meter (2 feet) and 0.9 meter (3 feet) above grade.

8.1.9

In addition to the foregoing, excavation work in residential areas shall be entirely enclosed, covered over, or roped-off.

February 1993 - Construction Safety Manual: Working Places, Ladders, and Scaffolding Page 183

9.0 WORKING PLACES, LADDERS, AND SCAFFOLDING

Every contractor and every employer of workmen has a legal and contractual responsibility to ensure that each place at which his men work is safe and that it remains safe so long as men work there. Similarly, each supervisor is responsible for ensuring that every man working under his direction or control has a safe working place and a safe means of getting to and from every working place.

Where work cannot safely be done on the ground or from part of a building or permanent structure, scaffolds, ladders, or other means of support shall be provided and properly maintained.


The Standards used for guidance in this section of the Construction Safety Manual are those of the American National Standards Institute, Inc. (ANSI) and US Code of Federal Regulations (CFR) 1910.28. Where scaffold manufacturers products meet other scaffold standards that are equivalent to or higher than ANSI requirements, then those products can be used. Scaffold products from different manufacturers shall not be mixed on a scaffold, unless they are specifically designed to be used together.

9.1 Working Places, General

9.1.1 Falls

Within Saudi Aramco, every working place shall be safe and of adequate dimensions. Where men, tools, or materials could fall 1.8 meters (6 feet) or more, a guardrail system (consisting of toprails and midrails) and toeboards shall be provided. Should the provision of these safeguards be impracticable, other means of preventing falls, such as safety belts, etc. shall be used. For further information, see Personal Protective Equipment, Section I.9, (9.6.5 and 9.6.6) of this Manual.

9.1.2 Access and Egress

A safe means of getting to and from a working place shall be provided and used. Ladders shall conform to the requirements set out in 9.2.

9.1.3 Lighting

Every working place and every means of getting to and from a working place shall be provided with adequate lighting which shall be properly maintained. (See SAES-P-123)

9.1.4 Prevention of Falls

Permanent decking, parts of a structure, walkways, footbridges, etc., which men use in the course of their work or for a permanent or temporary access, shall be provided with a guardrail system and toeboards (permanent or temporary) at all edges from which men, tools, or materials could fall 1.8 meters (6 feet) or more. Holes and gaps shall be guarded or securely covered. Stairs (permanent or temporary) shall have all treads properly secured and shall be fitted with handrails throughout their length and conform to the Uniform Building Code.

9.1.5 Ramps

Where the slope of a ramp exceeds 1 vertical to 4 horizontal, the ramp shall be fitted with stepping cleats at 0.3 meter (1 foot) intervals. When a ramp is to be used by the general public, its slope shall not exceed 1 vertical to 4 horizontal. Handrails shall be provided.


9.1.6 Falling Material

Where there is danger of men being struck by falling material, protective coverings shall be erected or No. 18 gauge wire, 1/2 inch mesh or equivalent, shall be securely fixed between the toeboard and midrail to prevent falling objects.

9.1.7 Hot Surfaces

Suitable precautions shall be taken to prevent men coming into contact with any hot surface.

9.1.8 Slipping and Tripping

Contractors are responsible for maintaining good housekeeping to prevent slipping, tripping, and falling. Oil spills, mud, scrap, and other debris must be cleared up immediately. Men shall not be permitted to walk or work on steel work or other surfaces on which paint or cement wash is still wet.

9.1.9 Roof Work

Where work is done on or from the roof of a building or structure, or where men have to cross, work on, or work from fragile roofs or surfaces, adequate protection in the form of crawling boards, roof ladders, or other suitable covering must be provided to prevent men and materials falling from or through the roof. Temporary guardrails shall be placed to prevent workers from falling. If roof work is accomplished on pitched roofs with a slope greater than 1:4, workers shall be equipped with safety belts that are securely anchored to the structure. During storms or high winds, workers shall not be working on a roof or scaffold that is exposed to the weather.

9.1.10 Insecure Structures

Unstable or weak structures shall be supported by guys, stays, supports, or other fixings where necessary. If work being done is likely to reduce the stability of an existing structure or building, bracing or other means of support shall be used. Unstable structures shall not be left unsupported over night.

No wall sector which is more than one story in height, shall be permitted to stand alone without lateral bracing, unless such wall was originally designed to do so and is in a safe condition to be self-supporting. All walls shall be left in a stable condition at the end of each shift by bracing support jacks, timbers and/or guy-wired, taking wind force and storm conditions into consideration.


9.1.11 Work Over Water

9.1.11.1

Where men work on, over or near water, a guardrail system and toeboards, fencing or other suitable barriers shall be provided for the protection of the worker.

9.1.11.2

Wherever the provision of a guardrail system and toeboards, fencing or other suitable barriers is impracticable, or if for any reason men are outside the protection of these safeguards, suitable life vests shall be worn and a safety belt or harness securely fixed to a dropline.

9.1.11.3

Approved rescue equipment that meets the requirements of GI 6.020 in the form of life rings with life lines, etc.; where necessary, a suitably equipped rescue boat shall be readily available, and properly maintained. Men shall be thoroughly trained in the use of all protective and rescue equipment, first aid and cardiopulmonary resuscitation (CPR).

9.2 Ladders and Stepladders

The safety of a ladder depends on four important factors: selection, condition, position and use. Ladders shall comply with the referenced ANSI or equivalent codes.

9.2.1 Selection

9.2.1.1

A ladder must be of the proper length for the job to be done. If it is to be used for access or as a working place, it shall ris e to a height of 36 inches to 42 inches above the landing place or above the highest rung to be reached by the feet of the man using the ladder.

9.2.1.2

Metal ladders, ladders with metal reinforced side rails, and ladders which are wet shall not be used near electrical equipment with exposed live conductors. Such ladders shall have a warning notice attached to guard against use near electrical equipment.

9.2.1.3

Aluminum ladders shall not be used where there is a likelihood of contact with materials harmful to aluminum, such as caustic liquids, damp lime, wet cement, etc.


9.2.2 Condition

9.2.2.1

Each ladder shall be examined before use. Those with split or broken side rails, missing, broken, loose, decayed or damaged rungs or cleats, or with other faulty equipment shall be tagged and removed from service.

9.2.2.2

Rungs shall be properly mortised into side rails. Cleats shall be inset by 2.25 centimeters (7/8 inch), or filler blocks used on the side rails between the cleats. Cleats shall be uniformly spaced 30.5 centimeters (1 foot) between centers.

9.2.3 Position

9.2.3.1

The side rails of a ladder shall be equally supported on a firm level surface. Boxes, blocks, barrels, etc. shall not be used as a means of support. The area at the base of a ladder must be kept clear. Ladders shall not be used in a horizontal position as platforms, runways or scaffolds.

9.2.3.2

Ladders shall not be supported on their rungs or cleats. Rungs or cleats shall not be used to support planks.

9.2.3.3

Whenever possible, ladders shall be set at an angle of 75o to horizontal ground (i.e., one meter out to four meters up).

9.2.3.4

Metal reinforcing shall be on the underside of the rungs and where reinforcing is on only one side of the side rails, that too shall be on the underside.

9.2.3.5

Both side rails of a ladder shall be evenly supported at the upper resting place. Side rails must be securely tied off to prevent movement. Where secure fixing is impracticable, other measures must be taken to prevent movement by securing at the base, using side guys, or stationing a man at the base. It must be understood, however, that a man stationed at the base will be unable to control a ladder more than 6 meters (20 feet) in length.


9.2.3.6

Where there is a possibility of a ladder being struck by moving vehicles or equipment, a man should be placed on guard or a space at the base should be securely fenced off. If a ladder is erected close to a doorway, the door should either be locked, shut, or be secured in the open position with a man on guard or properly barricaded.

9.2.3.7

Ladder landing places shall be provided at least every 9 meters (30 feet) of height and shall be fitted with a guardrail system and toeboards. Holes in decking through which ladders pass shall only be enough to permit passage of the man using the ladder.

9.2.3.8

A ladder should always be placed so that there is space behind each rung or cleat for a proper foothold. There should be no obstruction in the way of a man's foot, particularly at the landing platform. Here the rung or cleat should be level with the platform.

9.2.3.9

Where ladders have to be suspended, both side rails shall be lashed top and bottom so as to provide equal support. Where long ladders are used, they shall also be lashed at the center to prevent lateral movement.

9.2.4 Use

9.2.4.1

Where an extension ladder is used fully extended, the minimum overlap depends on the extension ladder length, and overlap should be as follows (examples):

9.75 to 10.97 meters (32 to 36 feet) = 1.22 meters (4 feet) overlap

10.97 to 14.63 meters (36 to 48 feet) = 1.52 meters (5 feet) overlap

Splicing or lashing ladders together shall not be permitted.

9.2.4.2

Before mounting a ladder, personnel shall check their shoes for freedom from grease, oil or mud. They shall always step through, not around, the rail extensions at the top of the ladder.


9.2.4.3

Single rung and single cleat ladder should be used by only one man at a time. When ascending or descending personnel shall face the ladder and keep both hands on the ladder. Personnel shall not run up or down or slide down a ladder at any time. The width of single cleat ladders shall be at least 38.1 centimeters (15 inches) but not more than 50.8 centimeters (20 inches) between rails at the top.

9.2.4.4

Men ascending or descending ladders shall not carry tools and materials in their hands. Tools may be carried in pockets or on special belts provided there is no risk of injury and movement is not impaired. Materials shall be raised or lowered using a handline after being securely tied or placed in a basket.

9.2.4.5

A man working on or from a ladder must always have a secured handhold and both feet on the same rung or cleat. If the work to be done requires the use of both hands, a safety belt is required, securely fixed to a dropline (life line). Only one person shall be on a ladder at a time.

9.2.4.6

Job-made ladders shall be constructed for intended use. If a ladder is to provide the only means of access or exit from a working area for 25 or more employees, or if simu ltaneous two-way traffic is expected, a double cleat ladder shall be installed.

Double cleat ladders on Saudi Aramco construction sites shall not exceed 4.5 meters (15 feet) in length.

Single cleat ladders shall not exceed 4.5 meters (15 feet) in length between supports (base and top landing). If ladders are to connect different landings, or if the length required exceeds this maximum length, two or more separate ladders shall be used, offset with a platform between each ladder. A guardrail system and toeboards shall be erected on the exposed sides of the platforms.

5.08 by 10.16 centimeters (2 by 4 inches) lumber shall be used for side rails of single cleat ladders up to 4.5 meters (15 feet) long.

5.08 by 10.16 centimeters (2 by 4 inches) lumber shall be used for side and middle rails of double cleat ladders up to 3.6 meters (12 feet) in length; 5.08 by 15.24 centimeters (2 by 6 inches) lumber for double cleat ladders from 3.6 by 4.5 meters (12 to 15 feet) in length.

Wood cleats shall have the following minimum dimensions when made of woods that meet ANSI requirements for ladders:


LENGTH OF CLEAT THICKNESS WIDTH Up to and including 50.8 cm (20 inches)

1.9 cm (.75 in) 7.62 cm (3 in)

Over 50.8 cm (20 in.) and up to and including 76.20 cm (30 in.)

1.9 cm (.75 in.) 9.52 cm (3.75 in.)

Cleats may be made of species of any other group of wood provided equal or greater strength is maintained.

Cleats shall be inset into the edges of the side rails one-half inch, or filler blocks shall be used on the rails between the cleats. The cleats shall be secured to each rail with three 10d common wire nails or other fasteners of equivalent strength. Cleats shall be uniformly spaced, 30.48 centimeters (12 inches) between centers.

9.2.4.7

Metal ladders shall not be used for work on electrical systems unless the ladders are specifically designed for that application.

9.2.5 Stepladders

Generally, the foregoing remarks on selection, condition and use of ladders apply equally to stepladders. The following requirements also apply:

9.2.5.1

To ensure stability, stepladders shall be spread to their fullest extent limited by manufacturer's braces when in use. Whenever possible, they should be placed at right angles to the work with either the front or back facing the work.

9.2.5.2

Do not stand, climb or sit on the stepladder top, pail shelf, braces or back section.

9.2.6 General

9.2.6.1

Ladders and stepladders shall be maintained in good condition at all times. Joints shall be tight, all hardware and fittings shall be securely attached, and movable parts shall operate freely without binding or undue play.

9.2.6.2

Ladders and stepladders must not be painted.


9.2.6.3

Where a ladder is carried by one man, the front end should be kept high enough to clear men's heads and special care shall be taken at corners and blind spots.

9.3 Scaffolding Components

9.3.1

All scaffold structures shall be erected with metal components approved per ANSI requirements or equivalent. Scaffolds shall be stored to prevent damage and to permit easy access for use. Scaffold erection plans (drawings) shall be submitted to Loss Prevention Department for review prior to men being allowed to work on the scaffold.

9.3.2 Tubing

Ordinary scaffold tubing is 4.8 centimeters (1-29/32 inches) in diameter and nominal wall thickness 0.4 centimeter (5/32 inch) and is referred to as two-inch nominal diameter tubing. It is mild steel and normally supplied in lengths of 6.4 meters (21 feet). Tubes must meet ANSI or equivalent requirements and must be free from cracks and surface flaws, laminations, excessive rust and other defects. The ends shall be cut square and cleanly. A tube shall not deviate from a straight line by more than 1/600 of its length measured at the center of the tube length.

9.3.3 Aluminum Tubing

9.3.3.1

Although the aluminum tubing is dimensionally interchangeable with steel tubing, it must not be used in the same structure; the difference in the elastic modulus of the two materials results in greater deflection in aluminum tubing for the same loading conditions.

9.3.3.2

Aluminum tubing shall not be used where there is likelihood of contact with materials harmful to aluminum such as caustic liquids, damp lime, wet cement and sea water.

9.3.4 Fittings

All fittings (couplers, clamps, etc.) shall be of a metal type approved to ANSI or equivalent requirements. They shall be examined regularly and care must be taken to ensure that moving parts are sound and well lubricated and that threads are not stripped.


9.3.5 Typical Scaffold Fittings

(Figures II.17 - II.22)

Base Plate: A 15 centimeter (6 inch) by 15 centimeter (6 inch) steel plate greater than 0.64 centimeters (1/4 inch) thick providing a flat bearing surface for load distribution from posts. It has an integral spigot and fixing holes for use with sills.

Screwjacks: Used for compensating variations in ground levels.

Standard Coupler: Also known as a Right Angle or 90o Coupler. A load bearing

coupler used for connecting two tubes together at right angles.

Adjustable Coupler: Used for connecting two tubes together at any angle through 360o. Not to be used where a load bearing standard coupler is required.

End-to-End Coupler: Also known as a Sleeve Coupler. Used for connecting two tubes end-to-end.

Reveal Pin: Inserted into the end of a tube and adjusted to form a rigid horizontal or vertical member between two opposing surfaces. It forms a solid anchorage to which a scaffold can be tied.

9.3.6 Planks

9.3.6.1

Planks shall be of rough timber and graded as scaffold planks without defects (2" x 9"), 5 centimeters (2 inches) thick by 23 centimeters (9 inches) wide, and shall conform to the following specifications:

9.4 Requirements Common to All Scaffolding

9.4.1 Foundations

9.4.1.1

A sound base is essential; therefore, the ground or floor on which a scaffold is going to stand must be carefully examined. Sand or made-up ground may need compacting to ensure there are no cavities. Such bases as floors, roofs, etc. may need shoring from underneath.

Scaffolds, including components, shall be capable of supporting without failure at least 4 times the maximum intended load.

9.4.1.2

Timber sills at least 23 centimeters (9 inches) wide by 3.8 centimeters (1-1/2 inches) thick (not scaffold planks) will be required to spread the load on sand, made up ground, asphalt pavement, wooden floors, and slippery surfaces. A sill shall extend under at least two posts.

9.4.1.3

Where scaffolding is erected on a solid bearing such as rock or concrete, small timber pads may be used in place of sills and nailed to prevent the base plates sliding off.

9.4.1.4

Concrete blocks, barrels, and other loose or unsuitable material shall not be used for the construction or support of scaffolding.

9.4.1.5

If used to compensate for variations in ground level, the screwjack shall not be adjusted to more than two-thirds of the total length of the thread. The base plate shall be of a type approved for supporting scaffolding posts. (See manufacturer's specifications.)

9.4.2 Posts

9.4.2.1

Posts shall be pitched on 15 centimeters (6 inches) by 15 centimeters (6 inch) steel base plates and at least 0.64 centimeter (1/4 inch) thick. Joints in posts should be staggered, i.e., joints in adjacent posts should not occur in the same lift. All posts shall be vertical.

9.4.2.2

The inner row of posts shall be placed as close as possible to the face of the building or structure. To avoid projections, the posts may be up


to 41 centimeters (16 inches) away from the wall or structure as necessary, provided that, where there is room to do so, the gap between the wall or structure and the inner posts shall be closed with planks on extended board bearers. The outer row of posts shall be positioned from the inner row of posts depending on the load requirements of the scaffold, and the working platform shall be fully decked out.

9.4.3 Runners

9.4.3.1

Runners shall be securely fixed to posts with standard couplers and shall be horizontal. Joints in runners should be staggered, i.e., joints in adjacent runners should not occur in the same bay. Runners should be secured end-to-end by sleeve couplers, not by joint pins.

9.4.3.2

Runners shall be vertically spaced no more than 2.0 meters (6 feet, 6 inches) to give adequate headroom along the platforms.

9.4.4 Bearers

Bearers should be installed between posts and securely fixed to the posts bearing on the runner coupler and secured with standard couplers. When coupled directly to the runners, the coupler must be kept as close to the posts as possible. These bearers must remain in position as they are a structural part of the scaffold.

9.4.5 Board Bearers

Board bearers shall be installed between bearers to accommodate differences in plank lengths.

Board bearers shall be secured to the runners between bearers where necessary to support platform units (planks). These may be removed when no longer required to support platform units.


9.4.6 Bracing

9.4.6.1

Cross bracing shall be installed across the width of the scaffold at least every third set of posts horizontally and every fourth runner vertically. Such bracing shall extend diagonally from the inner and outer runners upward to the next outer and inner runners. These braces should be fixed to the runners with standard couplers as close to the posts as possible. Where such a fixing is impracticable, adjustable couplers may be used to fix the braces to the posts. (See Figures II.23 and II.24.)

9.4.6.2

Longitudinal diagonal bracing shall be installed at approximately 45-degree angle from near the base of the first outer post upward to the extreme top of the scaffold. Where possible, such bracing shall be duplicated at every fifth post. On short but high runs, diagonal bracing shall be installed at an angle of 45 degrees from the base of the first outer post to the last outer post and shall alternate directions to the top of the scaffold. When bracing cannot be attached to the posts, this bracing may be attached to the runners, as close as possible to the posts. Only standard couplers or adjustable couplers may be used. Joints in braces shall be made with end-to-end or parallel couplers.

9.4.6.3

Temporary rakers (inclined load-bearing tube supports) brace the scaffold against the ground when setting out. These rakers are replaced by permanent braces when the scaffold has been plumbed, leveled and tied. Rakers must be secured with proper couplers at the scaffold and coupled to a ground stake.

9.4.7 Ties

9.4.7.1

It is essential that all scaffolds, with the exception of certain tower and mobile scaffolds (See 9.7 and 9.8), be securely tied to the building or structure throughout their length and height to prevent movement of the scaffold either towards or away from the building or structure. This should be done by connecting a tie tube to both runners or posts and coupling this to a two-way tie or column box tie assembly. (See Figures II.25 and II.26.)

9.4.7.2

Where the foregoing is impracticable, tubes may be securely wedged between opposing surfaces on the building or structure by the use of reveal pins and coupled to the tie tubes (Figure II.27). Where reveal ties are used, they shall not exceed 50% of the total number of ties. Two-way ties or column box ties shall be evenly distributed over the


scaffold area. To ensure the security of reveal ties, it is necessary to check frequently for tightness.

9.4.7.3

Ties shall occur at the top of the scaffold and at least every 7.9 meters (26 feet) vertically and 9.1 meters (30 feet) horizontally and at each end of the scaffold. All tie assembly connections shall be made with standard couplers.

9.4.8 Platform Units

9.4.8.1

All platform units (i.e., planks, fabricated decks, etc.) shall be closed planked with, whenever practicable, each plank resting on at least three supports. Planks shall extend over their end supports by not less than 15 centimeters (6 inches) and not more than 30.5 centimeters (12 inches).

9.4.8.2

Supports for scaffold planks shall be spaced with due regard to the nature of the platform and the load it will bear. (See Table II.2.)

9.4.8.3

Except on platform units adjacent to the surface of a cylindrical or spherical structure, planks shall be laid flush.

9.4.8.4

Planks shall be secured in position to prevent displacement by high winds.

9.4.8.5

Adequate space for men to pass in safety shall be provided and maintained wherever materials are placed on platform units or if any higher platform is erected thereon.

9.4.8.6

Platform units shall be kept free of unnecessary obstructions, materials, and projecting nails.

9.4.8.7

Platform units which have become slippery with oil or any other substance shall be cleaned, or otherwise removed and replaced.


9.4.8.8

Slopes in platform units shall not exceed 1 vertical to 4 horizontal and stepping cleats at 0.3 meter (1 foot) intervals shall be provided.

9.4.8.9

All platform units shall be closed planked for the full width of the scaffold structure.

9.4.9 Guardrail Systems and Toeboards

9.4.9.1

Guardrail systems (consisting of toprails and midrails) and toeboards shall be installed at all open sides and ends of all scaffolds and supports on no more than 3-meter (10-foot) centers from which men or materials could fall a distance of more than 1.8 meters (6 feet). Toprails shall be no less than 0.91 meter (36 inches) and no more than 1.14 meters (45 inches) above the working surface; midrails shall be installed equidistant between the working surface and the toprail. Toeboards shall not be less than 10 centimeters (4 inches) in height by 2.5 centimeters (1 inch) thick. Guardrail systems and toeboards shall be securely fixed to the inside of posts to withstand a lateral thrust of 200 pounds.

9.4.9.2

Landings: Safe landings shall be provided at the top of all ladders. Rings shall be eliminated above the landing level, and side rails shall extend 36 to 42 inches above the landing for mounting and dismounting. Where multiple ladders are required, solidly decked platforms shall be provided. Guardrails, intermediate rails and toeboards shall be erected on the outside edges and exposed sides of the platform.

9.4.10 Access

Access to a working platform is best achieved by providing a separate ladder tower or a cantilevered access platform so as not to obstruct the working platform and to minimize the risk of persons falling through gaps in the guardrail system or platform units. Access must be provided to working platforms.

9.4.11 Scaffold Ladders

Scaffold ladders provide the means of access and egress for scaffolds. They can generally be classified as follows:


9.4.11.1 Portable Straight and Extension Ladders (Figure II.24)

A straight ladder is a portable ladder that only consists of one section which determines its overall length. It cannot support itself or be adjusted in length.

An extension ladder is a portable ladder that cannot support itself but can be adjusted in length. It consists of two or more sections which are arranged to permit length adjustment. Its overall length is the sum of the length of all its sections measured along the side rails.

Portable straight and extension ladders shall have a firm base and be positioned with a slope of 1:4.

9.4.11.2 Vertical Ladder

A vertical ladder is a type of fixed ladder which is permanently attached to the horizontal or vertical components of a scaffolding.

The main criteria to consider in the use of a vertical ladder is clearance. The following clearance guidelines shall be used.

• General:

Safe clearances shall be maintained to prevent workers from bumping into, or snagging onto, projecting objects while ascending or descending the ladder.

• Climbing Side:

Ladders shall have a minimum clear perpendicular distance of 30 inches from the rungs to the nearest projecting object on the climbing side. When unavoidable obstructions are encountered, the minimum clearance distance may be reduced to 24 inches if deflector plates are provided.

• Back Side Of Ladder:

The perpendicular distance from the face of the rung on the climbing side to the nearest fixed object on the back side of the ladder shall not be less than 10 inches. When unavoidable, horizontal obstructions (e.g. beams, pipes, etc.) are encountered, the vertical toe clearances specified in the following sections, shall apply.

• Side Clearance:

The minimum clear distance to the nearest fixed object shall be 15 inches on each side of the centerline of single rung ladders.


• Vertical Clearance:

The minimum vertical toe clearance from horizontal obstructions shall be 1 1/2 inches below and 4 1/2 inches above the top edge of the rung.

• Multiple Ladders:

When two or more separate ladders are used with a landing platform, the side-step distance shall be a minimum of 15 inches from the centerline of the upper ladder to the near side of the lower ladder.

9.4.12 Workmanship

9.4.12.1

Scaffolding shall be erected, altered, and dismantled by experienced men working under the direction of a competent supervisor.

9.4.12.2

Posts shall be set accurately in place and checked vertically by using a spirit level or by using vertical lines on the building or structure.

9.4.12.3

Scaffolding couplers should be tightened with proper scaffolding spanners. The use of an ordinary spanner or tool giving greater leverage could damage the screw threads and render the coupler unserviceable.

9.4.12.4

Scaffolding materials shall not be thrown or dropped from heights.

9.4.13 Inspections

All scaffolds shall be inspected regularly by a competent Supervisor and after adjustments, modifications, adverse weather conditions, etc. Erected scaffolds and platforms should also be inspected continuously, by those using the scaffold, to insure that the scaffold has not been altered and is in a safe working condition.

9.5 Fabricated Tubular Frame and System Scaffolding

Fabricated tubular frame and system scaffolding are composed wholly or partly of prefabricated sections. There are many types of fabricated tubular frame and system scaffolding available which vary in design and methods of erection; however, the same basic principles set out in 9.4 apply and the following matters warrant particular attention. All scaffolds must be erected as per manufacturer's direction and limitations. A scaffold plan needs to be submitted to Loss Prevention Department for review. (See Figures II.28 to II.31)


9.5.1

To be erected, altered and dismantled by experienced men, under the direction of a competent Supervisor.

9.5.2

Periodic inspections shall be made of all parts and accessories. Broken, bent, altered, excessively rusted or otherwise structurally damaged frames or accessories shall not be used.

9.5.3

All fabricated tubular frame and system scaffolding shall be constructed and erected to support four times the maximum intended loads.

9.5.4

Scaffold posts shall be pitched on steel base plates and on timber sills or pads as necessary. Screwjacks shall be used to compensate for variations in ground level.

9.5.5

Scaffolds shall be properly braced by cross braces and longitudinal diagonal braces for securing vertical members together. The cross braces shall be of such length as will automatically square and align vertical members so that the erected scaffold is always plumb, square, and rigid. All brace connections shall be made secure.

9.5.6

The frames or posts shall be placed one on top of the other with coupling or stacking pins to ensure proper vertical alignment of the legs.

9.5.7

The frames and posts shall be locked together vertically by pins or other equivalent suitable means.

9.5.8

Fabricated tubular frame and system scaffolding over 38 meters (125 feet) in height shall be specially designed by a Professional Engineer. In Saudi Aramco, scaffold heights are limited to a maximum height of 12.2 meters (40 feet), unless a scaffold plan has been reviewed by the Area Loss Prevention Division representative prior to construction. Scaffolds above 12.2 meters (40 feet) should be constructed using scaffold contractors; however no scaffolds shall exceed 38.1 meters (125 feet) unless the design has been reviewed by an Area Loss Prevention Division representative, Consulting Services Department and approved by a qualified engineer. (See also GI 8.001, section 6.1.1.)


9.6 Tube and Coupler Scaffolds (Tube and Coupler Construction - Figure II.23)

9.6.1 Independent Tied Scaffold

An independent tied scaffold (also commonly known as a double pole scaffold) consists of a double row of posts connected together longitudinally with runners and with bearers at right angles to the runners. Braces and ties are essential for stability. Independent tied scaffold is the most common form of tube and coupler scaffolding and is divided into three groups.

In Saudi Aramco the height limitation of the tube and coupler scaffold shall not exceed 12.2 meters (40 feet) unless a scaffold plan proposing to use such a scaffold at a greater height has been reviewed by the Loss Prevention Department per the provisions of Section 9.5.8.

Bearers on heavy duty tube and coupler scaffolds shall be 6.35 centimeters (2.5 inches) outside diameter steel tube and be of nominal wall thickness 0.4 centimeter (5/32 inch).


9.7 Free-Standing Tower Scaffolds

A free-standing tower scaffold consists of four or more posts connected together longitudinally with runners and bearers at right angles to the runners, forming a square or rectangular tower (see Figure II.32). Alternatively, a free-standing tower scaffold may be constructed of a fabricated tubular frame or system scaffolding (see 9.5). A free-standing tower scaffold has a single working platform and is a common form of access scaffolding for painters and others who do work of a light nature and of short duration.

9.7.1 General Requirements

For general requirements, see 9.4 and where a fabricated tubular frame or system scaffolding is to be used, see 9.5.

9.7.2 Design, Loading and Dimensions

A free-standing tower scaffold shall have only one working platform and the maximum distributed load shall not exceed the load rating which is determined by the platform unit type and the scaffold duty.

The height from the base to working platform of a free-standing tower scaffold shall not exceed four times the minimum base dimension. In no case shall the minimum base dimension be less than 1.2 meters (4 feet).

9.7.3 Runners and Bearers

The vertical spacing of runners and bearers shall be 2.0 meters (6 feet, 6 inches). The lowest runners and bearers shall be as near to the base as possible. Runners and bearers shall be secured to the posts with standard couplers.

9.7.4 Bracing

Sway bracing is necessary on all four elevations to the full height of the scaffold. Plan bracing is also required at the base, at the top, and at every third lift to prevent racking.

9.7.5 Ties

Free-standing tower scaffolds more than 9.8 meters (32 feet) in height shall be adequately tied to a building or structure. Where tying to a building or structure is impracticable, one of the following methods of ensuring stability shall be used (see Figures II.33 to II.35):

1 Guy wires at a slope of approximately 45o connected to the working platform level of the tower.

2 Bottom corners of the tower securely anchored. 3 Outriggers extending to the ground.

The strength of the guy wires or of the anchorage used shall be calculated, having due regard to the horizontal wind forces and other known forces which may be applied to the tower. These calculations shall be reviewed by Loss Prevention Department.


9.7.6 Platform

The single working platform of a free-standing tower scaffold shall not project beyond the base area and the platform unit(s) shall be securely fixed in position.

9.7.7 Access

Where the means of access to the working platform is outside the tower structure, due consideration must be given to the effect of such means of access on the stability of the scaffold. Where a sloping ladder would cause instability, a securely fixed vertical ladder may be used.

9.7.8 Limitations

Free-standing tower scaffolds erected and used in accordance with these directions and with one working platform may be used up to a maximum height of 12 meters (40 feet) to the work platform. Free-standing tower scaffolds departing from these directions shall be specially designed.

9.8 Mobile Tower Scaffolds (Figure II.31)

The requirements for free-standing tower scaffolds in 9.7 also apply to mobile tower scaffolds with the exception that wheels are used in place of base plates and sills.

9.8.1 Foundations

Wheels or casters, not less than 12.7 centimeters (5 inches) in diameter, and fitted with brakes, which cannot be released accidentally, shall be securely fixed to the bases of the posts by lock pins or dowels.

A mobile tower scaffold shall only be used and moved on surfaces sufficiently firm and level to ensure stability. Where the scaffold is to be used on a suspended floor, it shall be designed to apply loads no greater than the bearing capacity of the floor.

Temporary foundations or track laid on soft or uneven ground to facilitate the erection and movement of the tower shall be constructed and anchored so that its bearing capacity is not exceeded due to imposed loading from the tower. The track shall be level and properly secured.

9.8.2 Operation

A mobile tower scaffold shall be moved only by pushing or pulling at the base. Force must not be applied at a height greater than 1.4 meters (4 feet, 6 inches) above the base. No men, equipment or materials shall be on the working platform or elsewhere on the structure while it is in motion. Wheel brakes shall be applied at all times when men are on the stationary mobile tower scaffold.


9.8.3 Limitations

Mobile tower scaffolds, erected and used in accordance with these directions, supported on four wheels and with one working platform, may be used up to a maximum height of 12 meters (40 feet). Mobile tower scaffolds departing from these directions shall be specially designed and properly secured (See 9.7.5).

9.9 Scaffolds for Tanks and Vessels

The weld shall be made with the same type of electrode as used for the main tank weld joints. Before the bracket is attached to the strap, the weld shall be inspected by a competent welding inspector or welding supervisor who will approve and accept the weld.

9.9.1.5

Brackets shall be inspected prior to each use and damaged or defective brackets shall be removed from service. Brackets shall be vertical and horizontal spacing shall not exceed 2.5 meters (8 feet) on centers.

9.9.1.6

A rigid guardrail system and toeboards shall be securely fixed to the uprights of the brackets (see Section 9.4.9). Alternatively, 3/8 inch diameter wire ropes may be used in place of toprails and midrails providing that they are securely fixed and kept taut by the use of turn buckles.


9.9.1.7

Whenever men are working, the platform shall be fully decked.

9.9.1.8

Excessive storage or accumulation of materials or platform units (planks) shall not be permitted.

9.9.1.9

The scaffold shall be designed to support a minimum load of 1.2 kPa (25 lb./sq. ft). No more than two persons shall occupy any given 2.5 meters (8 feet) of bracket scaffold at any one time. Tools and materials shall not exceed 34 kg (75 lb.) in addition to person(s) occupying the area.

10.0 HAND TOOLS AND POWER TOOLS

Hand tools are those tools for which the hand provides the motive force, e.g., picks, shovels, axes, crowbars, wrenches, saws, chisels, hammers, screwdrivers, etc. It is the contractor's duty to ensure that his workmen are properly instructed in the selection and use of the correct tool for the job. Tools constructed of good quality materials should always be used. Poor quality tools increase the risk of accidents and also reduce the efficiency of work.

Power tools, however, allow many jobs to be carried out more efficiently and with greater speed and accuracy. The correct use of power tools can only be achieved by the proper training of workmen, by proper maintenance, and by adequate site supervision. Many accidents have occurred because unskilled and untrained labor have been allowed to operate power tools in an incorrect manner.

February 1993 - 10.0 Hand Tools And Power Tools Page 222

10.1 Hand Tools, General

10.1.1 Quality

The contractor shall ensure that the finest quality tools shall be provided for all jobs where hand tools are used.

10.1.2 Cleanliness

The contractor shall ensure that hand tools are regularly cleaned and, where necessary, lightly oiled as a protection against corrosion.

10.1.3 Repair and Storage

All hand tools shall be regularly inspected before and after use, and before storage. If wear or damage is observed, the tool should be withdrawn from use for repair or disposal. The contractor shall ensure that the storekeeper maintains a record of all tools issued, repaired, and withdrawn from use. Proper racks and boxes shall be provided for the storage of hand tools.

10.1.4 Selection

The majority of accidents are caused by using an incorrect tool for the job. It is essential that the correct type, size, and weight of tool should be decided upon before any work is carried out.

10.1.5 Electrical Risks

All uninsulated metal tools are conductors of electricity. Where work takes place on or near electrical operations, only properly insulated and non-conductive tools should be used. Insulation should be checked at regular intervals by a competent electrician.

10.2 Individual Hand Tools, Precautions

10.2.1 Screwdrivers

It is essential that a screwdriver has the correct size of tip to fit the slot of the screw. If the screwdriver fits the screw correctly, the screw will be drawn into the correct position without unnecessary force being applied. Over-tightening of screws can lead to possible hand injury if the screwdriver slips.

Screwdriver shanks are not designed to withstand the twisting strain applied by a pair of pliers or more grips in order to obtain additional leverage. On no account should screwdriver handles be subjected to blows from a hammer or similar instrument.

Screwdrivers should never be carried in the pockets of coveralls or other clothing. A screwdriver can produce a serious wound.


10.2.2 Hammer

It is essential that the right kind of hammer be selected for the job. Hammer handles should be made from smooth timber or be made of an integral head and shaft of steel. Hammer heads should be secured to wooden handles with proper wedges.

10.2.3 Chisels

Cutting edges should be kept sharp at all times, and the original shape and angle should be maintained. Re-sharpened cold chis els should be suitably hardened and tempered to maintain them in a safe working condition. The chisel heads will mushroom in use. As soon as mushrooming is observed, the head should be reground with a slight taper around the edge to prevent chipping and reduce the tendency to re-mushroom. Eye protection should be worn at all times when a cold chisel is used.

On jobs where it is necessary to use a sledge hammer for striking the chisel, the chisel should be held by a second person using a pair of tongs.

Wood chisels should also be maintained in a sharp condition so that minimum pressure is exerted when making a cut. If the chisel is to be struck, only a wooden or soft mallet should be used.

10.2.4 Picks and Shovels

Picks and shovels shall be maintained in a serviceable condition at all times. Shovel blades should not be allowed to become blunt, turned, split, or jagged. Pick head points should be kept sharp and heat-treated so that the metal wears down in use and does not splinter or chip off. Shafts of picks and shovels should be kept free from cracks and splinters.

10.2.5 Spanners and Wrenches

Only spanners and adjustable wrenches of the right size should be used. When possible, use box-end rather than adjustable wrenches. The jaw should first be checked for any sign of opening out or splitting. Spanner and wrench lengths are graded to provide sufficient leverage on the nuts for which they are designed. Improvised extension to these tools is an unsafe practice and may cause the bolt tread to strip or cause shearing of the bolt. On no account should ordinary wrenches be struck by a hammer when tightening nuts. For heavy work of this nature, a properly designed slugging wrench should be used.

10.2.6 Pipe Wrenches

Pipe wrenches must be large enough for the job, the jaw teeth must be kept clean and sharp, and the knurl, pin, and spring should be kept free from damage. Pipe wrenches should never be struck with a hammer, nor should they be used as a hammer.


10.2.7 Pliers

Pliers should only be used when there are no other tools for the job. They are meant only for gripping around objects and should not be used as a wrench.

Care should be taken when cutting soft metal with pliers to ensure the scrap portion does not fly off and cause injury. If wire is cut under tension, then long handled pliers should be used. Where pliers are used for electrical work, they must be fitted with insulated handles. All pliers should be kept free from dirt and grit, and the movable parts should be lightly lubricated.

10.2.8 Jacks

Jacks should be marked with rated capacity and must be heavy enough and strong enough to raise and maintain the load. They should be placed on a firm and solid support, and the load should be positioned on the center line of the jack.

Once a load has been raised, it must be shored or blocked. The jack should never be relied upon to hold the raised load in position by itself. Extreme care should be taken when working under or near a raised load.

10.2.9 Hacksaws

The correct type of blade should be selected to suit the material to be cut. The blade should be set in a hacksaw frame so that the teeth are pointing in the forward direction, and sufficient tension should be applied to ensure blade is maintained rigid.

10.2.10 Hand saws

Many kinds of woodworking hand saws are available, and care should be taken to select the correct saw. All hand saws shall be regularly examined to ensure that the saw teeth are properly set so as to avoid binding in the timber which can cause the blade to buckle. The teeth should be kept sharp, clean, and lightly oiled. When the saw is not in use, the blade should be protected by a slotted piece of timber or a sheath.

Two-man saws should be operated by pulling only. The cut should be kept straight to avoid the blade buckling. The cut should be wedged open to prevent the timber from pinching the blade.

10.3 Power Tools, General

10.3.1 Quality

The contractor shall ensure that all portable power tools do not exceed 125 volts rating, are manufactured of sound materials, and are free from defects and properly grounded.


10.3.2 Repair and Storage

All portable power tools shall be stored in clean, dry conditions. The contractor shall provide a schedule of systematic inspection and maintenance for all power tools. All tools shall be returned to the storekeeper at the completion of each individual job. Power tools must not be left lying around the job site where they could be damaged.

Rotating tools should be switched off and held until rotation has completely stopped before they are set down. Tools must be disconnected before changing bits, blades, cutters, or wheels.

Power for tools can be supplied by compressed air, explosive cartridge, or electricity. All portable power tools must be equipped with properly functioning "dead man" switches.

10.4 Pneumatic Tools

10.4.1 General

10.4.1.1

An air compressor shall always be under the supervision of a competent person. It should always be sited in such a place so as to have adequate ventilation. Compressors shall not be permitted to operate in confined spaces without the provision of adequate exhaust ventilation.

10.4.1.2

All compressed air hoses shall be of the correct size to fit the tool being used. Any joint in the hoses shall be made with a proper coupler and secured by safety wire. The hose length shall be kept as short as possible and placed so as not to be subjected to damage.

10.4.1.3

Pneumatic tools require clean air to operate efficiently. In every line feeding a power tool, there shall be an adequate filter and lubricator.

10.4.1.4

During operation all air tools should be held firmly to prevent them spinning and jumping. This pressure should be maintained during the stopping process to prevent injury to the operator's feet and hands.

10.4.2 Individual Tools, Precautions

10.4.2.1 Jack Hammer and Concrete Breakers

The tool bit retaining spring shall always be securely in position to prevent the bit from dropping out. The bit must be kept sharp.


Ear, eye and foot protection shall be required when working with this type of equipment. See I.9 for other personal protective equipment requirements.

10.4.2.2 Rock Drill

It is extremely important that the operator maintains a firm grip with both hands and stands in a balanced position. Any other method of using the tool can cause serious bodily injury.

10.4.2.3 Grinding Machine

This tool is probably the most misused of all the power tools. Care should always be taken to ensure that the grinding wheel is free from defect before mounting. Any defect may cause the wheel to disintegrate as it gains momentum.

Only persons who have been instructed in the proper selection and fitting of grinding wheels should be allowed to install wheels on tools.

The proper size and type of wheel should be fitted to the tool so that the maximum permissible running speed of the spindle does not exceed the maximum periphery speed displayed on the grinding wheel. No grinding machine shall be used unless the maximum speed is clearly marked on the case. All wheels shall be fitted with adequate guards in conformance with ANSI B7-1-1988. (See Figure II.36.)

Floor stand and bench mounted abrasive wheels, used for external grinding, shall be provided with safety guards (protection hoods). The maximum angular exposure of the grinding wheel periphery and sides shall be not more than 90o, except that when work requires contact with the wheel below the horizontal plane of the spindle, the angular exposure shall not exceed 125o. In either case, the exposure shall begin not more than 65o above the horizontal plane of the spindle. Safety guards shall be strong enough to withstand the effect of a bursting wheel. (See Figures II.37 and II.38.)

Floor and bench-mounted grinders shall be provided with work rests which are rigidly supported and readily adjustable. Such work rests shall be kept at a distance not to exceed one-eighth inch from the surface of the wheel. (See Figure II.37.)

Cut type wheels used for external grinding shall be protected by either a revolving cup guard or a band type guard in accordance with the provisions of the American National Standards Institute, B7.1-1988 Safety Code for the Use, Care, and Protection of Abrasive Wheels. All other portable abrasive wheels used for external grinding, shall be provided with safety guards (protection hoods) meeting the requirements of this paragraph, except as follows:

• When the work location makes it possible, a wheel equipped with safety flanges shall be used.


• When wheels 2 inches or less in diameter which are securely mounted on the end of a steel mandrel are used.

Portable abrasive wheels used for internal grinding shall be provided with safety flanges (protection flanges) except as follows:

• If the wheels are entirely within the work being ground while in use.

• When wheels 2 inches or less in diameter which are securely mounted on the end of a steel mandrel are used.

When safety guards are required, they shall be so mounted as to maintain proper alignment with the wheel, and the guard and its fastenings shall be of sufficient strength to retain fragments of the wheel in case of accidental breakage. The maximum angular exposure of the grinding wheel periphery and sides shall not exceed 180o.

When safety flanges are required, they shall be used only with wheels designed to fit the flanges. Only safety flanges of a type and design and properly assembled so as to ensure that the pieces of the wheel will be retained in case of accidental breakage, shall be used.

All abrasive wheels shall be closely inspected and ring-tested before mounting to ensure that they are free from cracks or defects. (See Figure II.39.)

Grinding wheels shall fit freely on the spindle and shall not be forced on. The spindle nut shall be tightened only enough to hold the wheel in place. (See Figure II.40.)

All employees using abrasive wheels shall be protected by eye protection equipment.

Materials that require grinding shall be placed on the tool rest with moderate head-on pressure applied. Materials should not be forced or jammed into the wheel. Grinding the materials on the sides of the wheel is an unsafe practice which can damage the wheel. A grooved or damaged wheel must be replaced.

10.5 Cartridge Operated Tools

10.5.1 General

Cartridge operated tools have a great advantage in that they can be used in almost any situation without the inconvenience of trailing leads or hoses. However, it is essential that these tools be operated only by properly trained personnel who are over 18 years of age. The contractor shall ensure that each man required to operate such a tool will undergo a thorough training period and be certified by the tool vendor. Use of cartridge operated tools will be in accordance with Saudi Aramco GI 2.100, ANSI A10.3-1985 and the manufacturer's specifications and shall be subject to review and concurrence by the Loss Prevention Department.

10.5.2 Storage

Safe and secure storage for cartridges and tools must be provided on the job site. Storage must be fire proof, dry, must be capable of being locked and should be sited in a clear, but easily accessible location where constant supervision can be maintained.

Cartridges and tools must not be stored together. A storage unit providing positive physical separation of cartridges and tools (i.e., a wall or partition) is required.

Warning to be posted where cartridges are stored: "DANGER - NO SMOKING Cartridge Storage".

Ventilation must be provided in the store. Cartons of cartridges must not be stacked against the wall and ventilation spaces must be left around the cartons. Only one carton of each strength cartridge shall be open at any one time. All empty cartons, and intermediate packing, must be removed at once.

Tools must be stored in their carrying cases. No loose cartridges must be in the carrying cases; all cartridges must be in their color coded boxes.

Only authorized personnel must be allowed access to the store.

10.5.3 Selection and Training of Personnel

No person may operate, clean, maintain, or repair any cartridge tool without possessing a certificate of competency, issued by an accredited tool vendor or manufacturer's representative, which identifies the particular model that the person is qualified to handle.

Personnel for training must be selected with the following points in mind:

1 Must be over 18 years of age. 2 Must be physically fit and have full use of both hands and both eyes. 3 Should ideally be a tradesman, e.g. plumber, mason, electrician,

joiner/carpenter, etc. 4 Storemen may also need to be trained if they are required to clean and

maintain the tools.


Training, both theoretical and practical, must be given by a competent instructor.

The training must follow the manufacturer's instructions as contained in the handbook of each particular model.

10.5.4 Personal Protective Equipment

Eye Protection shall be worn by the operator and his assistant whenever using the tools. Goggles must be of a satisfactory standard designed to withstand high speed impacts and/or, penetrations.

Ear muffs will be available for use at any time and shall be used in confined spaces.

Safety belts may be required in certain situations where the recoil from the tool could cause an operator to loose his balance.

10.5.5 Issue and Returns

Contractors will ensure that a full register of the serial numbers of each tool is made and kept up to date.

A log inventory system of issuing and returning cartridges and tools against signatures must be initiated and maintained. See Figure II.47: Cartridge/Tool Issuance Control.

Only personnel in possession of a user certificate will be allowed to withdraw tools or cartridges from the store.

Only the minimum number of cartridges required for that particular shift's operation should be issued at any one time.

Cartridges and tools must not be left on the job site at lunch break or at end of shift but must be returned to the store for safekeeping.

Any loss, either of tools or cartridges, must be reported, at once, to Saudi Aramco project proponent.

10.5.6 Work Permits

Work Permits will not normally be required for use on job sites.

Where tools will be used in restricted areas (as defined in GI 2.100 Work Permits), a Hot Work Permit must be obtained before work commences.

10.5.7 Use

No person may operate, clean, maintain or repair any cartridge tool without possessing a certificate of competency which identifies the particular model that person is qualified to handle.

The manufacturer's operating instructions must be followed at all times.


Cartridges are manufactured in different calibers and strengths. There are three sizes: .25 short, .27 short, and .27 long; and, four strengths, as follows:

POWER LEVEL NUMBER COLOR CODE LETTER CODE

Low 3 Green L Low/Medium 4 Yellow LM Medium/High 5 Red MH

Extra High 6 Purple/Black EX

It is, therefore, imperative that the correct size and strength of cartridge required for the tool, the fixing, and the material to be fixed onto be properly determined. A wrongly sized cartridge will cause a stoppage or misfire.

Using a cartridge which is too powerful could cause a ricochet or a spalling or fracture of the material.

The following General Safety and Operating Rules are common to all types of tools:

1 As soon as the tool is removed from its carrying case, check to make sure that a cartridge is NOT LOADED.

2 Inspect the tool before use each day to ensure that it is complete, in good condition (e.g., clean), and that the safety devices are in proper working condition.

3 Any tool that is not in proper working order or that develops a defect during use, shall be immediately withdrawn from service and not used until properly repaired.

4 Tools shall not be loaded with a cartridge until just prior to the intended firing time. When loading a tool, point it away from you and anyone else. Never walk around with a loaded tool; load it where you are working. Never leave the tool loaded when not in use. Loaded tools shall not be left unattended.

5 Never try to operate the tool without the end of the barrel hard against the fixing surface.

6 All tools shall be used with the correct shield, guard, or attachment recommended by the manufacturer.

7 Fasteners shall not be driven into very hard or brittle materials including, but not limited to, cast iron, glazed tile, surface hardened steel, glass blocks, hollow tile, terra cotta, marble, granite, slate, etc.

8 Driving into soft or easily penetrable materials shall be avoided unless materials are backed by another material that will prevent the pin from passing completely through and creating a flying missile hazard on the other side. Careful inspection of all materials should be made before deciding on the use of a cartridge tool.


9 No pins shall be driven into a spalled area caused by an unsatisfactory shot, or into any existing hole in the material. Care should be taken to ensure that the new fixing is at least two inches away from any previous hole, and a similar distance from any welded joint.

10 Pins must not be fired into corner bricks, mortar joints, and must be at least four (4) inches (100 mm) away from the edge of concrete or brick work and one-half inch (12 mm) from the edge of steel.

11 Ensure that the correct strength cartridge is used for the pin, fixing and material involved. For the first, or test firing use the weakest cartridge. Too strong a cartridge may result in over penetration, or the fastener may rebound or ricochet.

12 The tool must be held at right angles to the job when firing.

13 In the event of a misfire, the tool should be re-triggered without moving the tool from the work face. If the shot again fails, then the tool must be held firmly in the firing position for at least 30 seconds to allow for a possible "Hang Fire" in the cartridge. The removal of the misfired cartridge must be as per the manufacturer's instructions. Do not use nails, knives, etc., to pry the cartridge loose.

14 Recoil from firing can throw an operator off balance, especially when working from ladders or scaffolds. Care must be taken to ensure that the operator has a secure and safe work area. Safety belts should be used if necessary.

15 Do not leave cartridges loose on the job site or in the carrying case or carry them in your pockets. Cartridges are of the 'Rim Fire' type and could explode accidentally if in receipt of a knock from a pin, fixing, or even a bunch of keys.

16 Before returning the tool to the stores, ensure that it is clean and complete and that all cartridges are in their correct color coded box.

10.5.8 Maintenance and Repair

Before any repair/maintenance work is carried out, check to make sure that the tool is NOT LOADED with a cartridge.

No person may operate, clean, maintain or repair any cartridge tool without possessing a certificate of competency which identifies the particular model that the person is qualified to handle.

Tools must be dismantled, as far as the manufacturer's instructions indicate, at least once every week and checked for defects and excessive wear before being cleaned and oiled. If any defect is found, the tool must be made serviceable before being issued for use.


Only manufacturer's authorized spare parts are to be used for repair/replacement.

NO CARTRIDGES must be allowed in the repair/maintenance area. Test firing of repaired tools must be done in a safe location away from work and store or office areas.

10.6 Electrically Operated Tools

10.6.1 General

10.6.1.1

All electrically operated hand tools shall be rated and used at a voltage not exceeding 125V to ground.

10.6.1.2

Before any electrical tool is used, a careful check shall be made by the supervisor to ensure that the supply voltage is within the range marked on the information plate on the tool. Ground Fault Circuit Interrupters (GFCIs) are required for all 120 volt, single phase, 15 and 20 ampere receptacle outlets on construction sites which are not a part of the permanent wiring system.

10.6.1.3

All electrical power hand tools shall be of the double insulated type or properly grounded.

External metal parts of double insulated tools (drill chucks, saw blades, etc.) are insulated from the electrified parts inside the tool and, under normal conditions, contact with electrified parts of the tool does not take place. However, under wet conditions, rain, condensation, high humidity, damp locations, etc., the hazards are as great as with faulty grounded tools. All electrical tools are hazardous when used damp or wet, but with double insulated tools the moisture coupled with metal dust, carbon dust, etc. can form a conductive path from inside the tool to the surface through the ventilation holes or cracks. Since there is no ground wire to carry this current away, the user can receive an electric shock. Double insulated tools, like all electric tools, must be kept dry and should not be used without a ground fault circuit interrupter.

10.6.1.4

All tools shall be used with extension cords which are as short as possible. All extension cords shall be fitted with grounding pin and blades to fit the socket outlet on the distribution board. Extension cords shall be of the three-wire conductor type. Plugs and sockets must meet the National Electrical Code requirement with respect to grounding and polarity.


Overcurrent protection shall be provided to extension cords in accordance with the requirements of the National Electrical Code Article 240. Factors to be considered for adequate overcurrent protection are: type of conductors, size, and length of run.

Example: Consider electrical equipment being used on a construction site that may require 15 or 18 ampere (amp.) capacity. Construction plans call for three No. 12 AWG (wire size) copper conductors which run to a 20 amp. receptacle (120 v) 40 feet from the electrical panel box. This circuit is protected by a 20 amp. circuit breaker. Is this a problem? Yes - There may be three problems: (1) the size of the conductors, (2) the length of cable run and, (3) the circuit breaker size.

In order to prevent an employee from receiving an electric shock, the breaker size and receptacle should be reduced to 15 amp. or the conductors changed to a No. 10 AWG so that the breaker can function at 20 amp. when required. Leaving the circuit the way it is would allow considerable electrical leakage without tripping the circuit breaker. Also conductor insulation would be subject to heat damage causing electrical leakage and fire. Heavy duty construction type extension cords are required for 20 ampere circuits, No. 14 AWG or larger size for 100 feet of run length. (See Figure II.41.)

10.6.1.5

Where it is necessary to make electrical splices, these shall be made with proper connector blocks or by plug and socket connectors. Taped joints shall not be permitted.

10.6.2 Maintenance and Storage

A proper inspection and maintenance routine shall be established by the contractor for all electrical tools. The inspection and maintenance of all tools shall be carried out at least once in every working week by a competent electrician.

All tools shall be stored in a clean, dry place, and a record of issue and receipt shall be maintained by the storekeeper.

10.6.3 Personal Protective Equipment

The contractor shall ensure that all operators are provided with eye, head, and ear protection. If there is any likelihood of harmful dust being emitted, dust respirators should be used.

10.6.4 Individual Tools, Precautions

10.6.4.1 Grinders

All grinders shall be equipped with a protective guard which allows only the working part of the wheel to be exposed. This guard must not be removed.


Grinders shall be clearly marked with their maximum running speed. The maximum running speed of the spindle must not exceed the maximum periphery speed marked on the grinding wheel. Wheels should be checked for defects before mounting. All defective wheels must be destroyed. (See Figure II.40.)

10.6.4.2 Drills

Care should be taken not to drill too large a hole at one time. Drilling of large holes should be done in stages by using small bore drills and gradually increasing the size as necessary. If this is not done, the drill may bind on breakthrough, and the torque set up could twist the tool against the user's wrist.

10.6.4.3 Saws

Hand operated circular saws shall be fitted with spring loaded guards which allow only the working part of the blade to be exposed. (See Figure II.42.)

Portable table saws shall be provided with adjustable guards, anti-kick-back devices, and push-type start/stop buttons within easy reach of the operator. (See Figures II.43 and II.44.) Fixed table saws shall be hard wired to an emergency electrical disconnect switch that has the capability of locking out in addition to having start/stop buttons at the operator's location, etc. Portable table saws must be unplugged for repair, maintenance, or when not in use.

Where a provision is made for a table saw riving knife to be fitted, it shall be kept clean and properly adjusted to the work at all times. Push sticks must be provided and used when necessary on all bench saws.

The work area shall be cleaned to prevent excessive build-up of sawdust and scrap wood.

Operators shall wear eye and hearing protection.

10.6.4.4 Radial Saws (Figure II.45)

Radial saws must be provided with:

• An upper hood to enclose the top portion of the blade down to a point that includes the end of the saw arbor. The sides of the lower, exposed portion of the blade must be guarded to the full diameter of the blade by a device that automatically adjusts to the thickness of the stock being cut.

• Anti-kickback dogs (on both sides of saw) designed to provide adequate holding power for all thicknesses of ripping stock.


• An adjustable stop limiting the forward travel of the blade beyond the distance necessary to complete the cut in repetitive operations.

• A saw housing which automatically returns to the starting position.

• A marking on the hood showing the direction of the saw rotation. In addition, a permanent label must be affixed to the rear of the guard, reading: "DANGER. DO NOT RIP OR PLOUGH FROM THIS END."

• Start/stop buttons at the operator's position. Additionally, in the case of fixed saws, each saw must be wired to an emergency electrical disconnect isolation switch capable of locking out the saw.

11.0 PAINTS AND COATINGS

In addition to the usual hazards associated with construction activities, workmen engaged in surface preparation and paint application can be exposed to the dangers of fire, explosion, chemical burns, toxic fumes, dust, and insufficient air. This section of the manual discusses these hazards and how to minimize them.

SAES-H-102 Safety Requirements for Painting

Steel Structures Painting Council. Steel Structures Painting Manual, Volumes 1 and 2.

United States of America Code of Federal Regulations, 29 CFR 1910.1000 Air Contaminants.

11.1 Flammability Hazards of Coating Materials

11.1.1 Flammable Materials

In paint systems, it is normally the organic solvent vapor that is flammable. In the Saudi Aramco paint system, all the solvents (except for the water based paints) present a fire hazard.

11.1.2 Flash Point (Definition)

The flash point is defined as the lowest temperature at which a liquid will give off sufficient vapor to ignite when exposed to an open flame. For most paint solvents in the Saudi Aramco system, the flash point is less than the normal ambient temperatures in Saudi Arabia. The danger of fire exists virtually always when solvents are in use.

11.1.3 Flammable (Explosive) Limits (Definition)

The lower and upper flammable (explosive) limits define the range of vapor/air concentrations that are potentially explosive. The lower flammable (explosive) limit (LEL) is typically on the order of 1% to 2% by volume, a level readily obtained in

February 1993 - 11.0 Paints And Coatings Page 251

the area near opened solvent containers and near the nozzle of a spray painting gun in operation.

11.1.4 Fire Precautions

Solvents in paints constitute a significant fire and explosion hazard when in the presence of ignition sources. No painting should be carried out within 75 feet of potential ignition sources, e.g., welding, flame-cutting, smoking areas, or sparking tools, unless conditions warrant greater clearance.

Ventilation equipment should be used to maintain a maximum level of solvent concentration, typically below 10% of the LEL.

All electrical lighting and equipment shall be explosion-proof when required in areas where solvent vapors are likely to be present.

All electrical equipment such as switches, panel boards, electrical motors and associated equipment must be de-energized before spray painting to eliminate explosion hazards.

Solvents and solvent based paints shall not be applied to surfaces exceeding Saudi Arabia summer ambient temperatures.

The use and storage of flammable paints and solvents shall be kept to restricted areas and these areas should be suitably marked with the appropriate warning signs. Flammable paints should be kept in a special building or in a sun shelter.

Fire extinguishers should be located at the work area and the area Loss Prevention representative/Fire Chief shall agree upon their suitability.

Work areas should be kept as clean as practicably possible.

11.2 Health Hazards Associated With Paints

Many paint ingredients are harmful to humans; most people can withstand these materials over a short time and in small quantities. However, some people are immediately sensitive to some ingredients and almost everyone will be affected to some degree if exposed for sufficient time.

There are two major groups of irritants: toxic materials and dermatitic or skin irritating materials.

11.2.1 Toxic Materials

The most abundant toxic materials found in paints and coatings are solvents. Other toxic materials in paints include pigments (lead), binders (epoxies, polyesters) and additives (organotin). Also, dust from cleaning operations or application of the paint can generate toxic materials. These toxic materials can enter the body through breathing, ingestion or skin absorption. Most solvents are toxic to some degree depending on exposure. The degree of toxicity can be measured by the Permissible Exposure Limit (PEL) expressed as parts per


million (ppm) or milligrams of particulate per cubic meter (mg/M3) of solvent in air over an exposure of 8 hours a day five days a week with no ill effects.

11.2.2 Dermatitic Materials

Dermatitic materials irritate the skin which, if left untreated, can cause infections or ulceration.

Solvents have a tendency to dissolve and remove natural oils and fats from skin. Certain binders such as epoxy resins may also irritate the skin.

Other chemicals used in paint related work should be handled with care (e.g. paint removers, acid and alkaline cleaners).

11.2.3 Prevention of Health Hazards

Many solvents and coatings contain hazardous ingredients. A copy of the appropriate Material Safety Data Sheet (MSDS) should be obtained for all materials used, studied carefully, and the required safety precautions implemented.

The following precautions should minimize health hazards:

• Identify and seal all toxic and dermatitic materials when not in use.

• Adequately ventilate all painting areas and provide National Institute for Occupational Safety and Health (NIOSH), Mine Safety and Health Administration (MSHA)-approved or equivalent respiratory protection where necessary. All workmen spray painting shall wear chemical cartridge respirators or airline hoods depending upon the hazards of the paint.

• Minimize dust during surface preparation, and dispose of coating residue in accordance with the recommendations of the Environmental Engineering Division, Process and Control Services Department.

• Wear the appropriate personnel protective equipment for the work being carried out.

• Avoid touching any part of the body and wear protective equipment (e.g. gloves, Tywag suits, etc.) when handling dermatitic materials. Personnel involved in painting shall wash thoroughly before eating and at the end of the day.

• Use ventilation control or respirators when working with paint removers containing toxic solvents.

11.3 Ventilation in Confined Spaces

A supply of clean air is a necessity for all operations involving the application of coating materials, and the paint curing/drying process. A high quality air supply is also required for life support (refer to GI 8.003 - Breathing Apparatus).


Ventilation is a necessity when painting in confined areas because solvents tend to be heavier than air and migrate to lower levels. The fresh air inlet of the ventilation system should be located near the top of the confined space, and the discharge should be located near the bottom, positioned to eliminate dead air spaces. Supplementary fans may be necessary to ensure good air circulation.

Natural ventilation through open man ways, etc. is rarely sufficient to keep local vapor concentrations to a safe level in terms of PELs or LELs. As a general rule, forced ventilation shall be used, especially in small enclosures and always during spray painting.

Ventilation requirements are proportionally greater for vessels with a capacity smaller than 1580 m3 (10,000 BBL's or 56,000 cu ft). The recommended ventilation requirements for various vessel capacities are shown in Table II.6; ref. SAES-H-102.

Ventilating to 10% of the LEL considerably reduces the likelihood of fire or explosion; however, this level will no doubt exceed the Permissible Exposure Limits for toxic materials. Hence, supplied air respiratory protection is required in confined spaces.

The preparation of air used for life support involves the following factors: PEL's of nuisance and toxic dusts; fume, gas and vapor content; air temperature. Air required for breathing apparatus shall meet the requirements of GI 8.003, Breathing Apparatus.

11.4 Surface Preparation

Equipment and materials that are used in surface preparation for paints and coatings can be hazardous if used carelessly. There are several methods for preparing surfaces and these include:

• Blast cleaning where abrasives in the form of sand, iron shot, grit, slag, etc. are used. Other types of blast cleaning use high pressure water or steam.

• Hand or power tool cleaning includes grinders, sanders, rotary wire brushes, impact tools, chisels, hammers.

• Chemical cleaning using paint removers, or solvents, alkali, acids or detergents.


11.4.1 Abrasive Blast Cleaning

This section covers blast cleaning using abrasives in the form of sand, iron shot, grit, slag or similar materials.

Abrasive blast cleaning operators shall have pre-placement physical examinations, including chest X-ray and pulmonary function tests with repeat tests at least every two years.

The abrasive blast cleaning operator shall wear an air supplied protective hood approved (NIOSH/MSHA or equivalent) for the type of abrasive material being used and any other toxic contaminants (lead, zinc, etc.) that are present. Where blast cleaning assistants could be exposed to silica sand dust or toxic contaminants, then self-contained or air supplied breathing apparatus shall be worn by the assistant. The breathing apparatus and air quality specification shall meet the standards referenced in GI 8.003, Breathing Apparatus. Personnel (e.g. maintenance, workers handling abrasive supplies or clean up crews) within the range of rebound abrasive contaminants shall wear approved (NIOSH/MSHA or equivalent) dust-filter respirators for the specific airborne hazards.

A bonding system that bonds nozzle, hose, blasting equipment and the material being cleaned shall be provided, and this bonding system shall be grounded to prevent a build up of static charges. Ground continuity tests shall be conducted periodically to ensure proper grounding.

To prevent ignition of hydrocarbons in classified areas, the appropriate precautions listed in GI 2.100, Work Permit System, must be followed.

11.4.2 Hydroblast and Steam Cleaning

Hydroblast cleaning uses a high pressure ambient temperature water jet and steam cleaning uses a high pressure and high temperature steam jet. Extra caution should be exercised when using such equipment. These types of equipment are used for removing dirt or rust scales and the personal protective equipment requirements are shown in Table II.7.

11.4.3 Hand and Power Tool Cleaning

This section briefly covers the safety aspects of hand and power tools used for surface preparation.

Particular attention should be paid to eye protection to guard against flying particles, and where necessary, ear protection should be provided to prevent long term hearing loss per SAES-A-105, Noise.

Tools should be correctly selected for the purpose, and also operated and maintained to the manufacturer's instructions.

Suitable respirators should be used if contaminant levels exceed Permissible Exposure Limits.

Extreme care should be used if tools have the ability to create sparks.


11.4.4 Chemical Cleaning

This section is concerned with four types of chemical cleaners (organic solvents, alkalines, acids and detergents) used to assist in the removal of surface contaminants such as light oils, greases and rust.

Solvents such as kerosene, mineral spirits, and turpentine are used to dissolve and remove oil contaminants. Hazards associated with solvents include their flammable, toxic and dermatitic characteristics. Safety precautions regarding these solvents are included in sections 11.1 and 11.2.

Alkaline cleaners are composed of highly alkaline salts with wetting agents and/or soaps. They function by wetting, emulsifying, dispersing and solubilizing surface contaminants, and are generally used at elevated temperatures.

Acid cleaners are generally composed of strong acids. They remove contaminants by chemical attack and are primarily used to remove metal scales such as rust.

Detergent cleaners are comparable to alkaline cleaners except they are generally used at low temperatures (60 to 100 degrees Celsius).

For all of the above chemical cleaners, personal safety precautions must be taken to protect personnel from materials and conditions that present fire hazards or cause personnel to experience dermatitic or toxic effects (such as inhalation effects, skin burns, or eye irritants).

When using chemical cleaners, appropriate eye and body wash facilities shall be available in the immediate area to minimize the effects of chemical burns in the event of an accident.

Chemical cleaning agents such as solvents shall not be used for cleaning personnel.

The following solvents shall not be used for cleaning purposes due to the very toxic nature: benzene, gasoline, carbon tetrachloride, and chlorinated hydrocarbons.

11.4.5 General Safety in Surface Preparation

Instruction and training of operators about correct use of the cleaning agents and equipment are essential.

Surfaces other than those receiving preparation should be protected from damage due to cleaning operations.

Where operators are using equipment such as blast cleaners or power tools, they must have safe footing. Extra caution should be taken on scaffoldings.

Never point a cleaning gun or nozzle at anyone or any part of your body.


Equipment such as blast guns and power tools must have automatic controls that shut off the flow of abrasive and propellant if for any reason the operator releases the control switch.

Power tools should be properly grounded to prevent electric shock.

All manufacturers recommendations on protective guards shall be implemented.

Fire and explosion hazards always exist when using solvents, especially in confined areas. Adequate ventilation must be provided.

11.5 Personal Protective Equipment

Personal protective equipment is required for the majority of operations that involve surface preparation or paint application. The amount and type of personal protection depends on the work being carried out and the location. Table II.7 gives a summary of essential personal protective equipment that must be worn by personnel carrying out specific duties. In addition, all personnel on Saudi Aramco industrial facilities and potentially hazardous areas must wear safety shoes, a hard safety hat and safety spectacles. Other protective details such as gloves, face shields, overalls and hearing protections should be addressed to either the area Loss Prevention or Industrial Hygiene offices.

11.6 Paint Application

There are numerous hazards associated with paint application and this section is concerned with air and airless spraying, together with brush and roller painting.

11.6.1 Paint Materials

The majority of paint solvents, many pigments and some binders are toxic in addition to having potential dermatitic hazards. Refer to the Material Safety Data Sheet (MSDS) for information concerning the hazards associated with their use.

In that, solvent based painting materials also present a fire and explosion hazards, painting shall not be carried out near an ignition source. Also, additional care should be taken to provide adequate ventilation in confined spaces.

Spraying paint using air or airless systems can be very hazardous and should only be used by trained operators.

11.6.2 General Safety In Paint Application

All personnel involved with the application of paint to surfaces should wear the appropriate personal protective equipment for the work being carried out at a given location. For some paint jobs personal protective equipment may have to exceed the requirements specified in Table II.7 due to the nature of the work being performed. Some examples of these jobs are above ground and water operations, use of special paints, etc.

All pressurized equipment should be handled carefully. Operators and their assistants should know how to operate and de-energize the equipment in accordance to manufacturer's recommendations.

No spray gun should be pointed at anyone or part of the user's body.

The spray painting operation should be conducted from the upwind side of the object being coated, wherever practicable.


Before using airless spray equipment, all guards recommended by the manufacturer shall be in place and the system shall be in good order and correctly grounded to prevent static build-up.

Prompt professional medical aid shall be available to any person receiving paint injuries.

The area around spray painting activity should be enclosed by hardboard fence or equivalent to protect outside personnel from paint over spray.

11.7 Scaffolding and Ladders

Details concerning the use and hazards associated with scaffolding and ladders are included in Section II.9 of the Construction Safety Manual.

Only good condition, correctly erected equipment shall be used that meets industry standards (ANSI) or equivalent. Users and erectors of such equipment should be trained about its use and limitations.

11.8 Tarring Operations

Tarring operations are commonly used in roof work, and hazards associated with this type of work include body burns, fire and toxicity. Precautions that are required for tar operations include:

• The heating of tar shall not be carried out on roof tops or in similar potentially hazardous locations.

• Tar heating operations shall be carried out using approved fuel gas in the correct cylinders. The heating operations shall be at ground level and at a minimum distance of 4.5 m (15 feet) away from fuel gas cylinders, buildings or similar structures.

• The transferring of hot tar to its required location shall be carried out using the safest mode of transport available (preferably pumped). Lifting of hot asphalt in buckets is not allowed.

• The temperature of the asphalt shall be monitored with a temperature gauge and must not exceed 4500F at any time during the tarring operations.

In addition to personal protective equipment (safety shoes, safety glasses and hard hats), the following shall be provided for all personnel directly involved in tar operations: face shields, leather gloves, cotton overalls, and heat resistant aprons. Also, respiration protection may be required in confined spaces.

A competent person is a person who, by possession of a recognized pertinent degree or certificate of professional standing, or who by extensive knowledge, training and experience has successfully demonstrated the ability to solve or resolve problems relating to safe crane operations and procedures (e.g. Rigger Technician, Crane and Rigging Specialist, etc.). A competent person shall supervise all lifts.

1.2 Saudi Aramco Crane Operations (General Requirements)

Before beginning any crane operation, the supervisor and operator should complete the pre-operation checklist (Figure III.1). A lift plan required as a part of this procedure must provide the following information:

1. Crane radius 2. Boom length 3. Safe working limits of the crane (load chart) 4. Weight of the load 5. Ground and site conditions 6. Placement of the crane 7. Swing and tail clearances 8. Necessary communication to be used


9. Explanation of hand signals 10. Rigging hardware 11. Rigging sketch for critical or hazardous lifts 12. Rated capacity of rigging components 13. Sling angles 14. Strain calculations 15. Wind velocity 16. Load moment indicator 17. Other

One competent person shall be placed in charge of the lift with the responsibility of explaining in detail, the duties of all involved in the lift before the actual lift commences. The outriggers must be fully extended prior to the lift, and the rubber tires must be off the ground (see Figure III.2, Crane Lift Plan).

Cranes shall have a valid Crane Safety inspection sticker issued by the Saudi Aramco Crane, Communication, and Facilities Inspection Unit. (See GI 7.030.)

1.3 Saudi Aramco Crane Operator Qualifications

A valid SAG heavy equipment license and Saudi Aramco Crane Operator Certificate are required for all contractor mobile crane operators. Contact the Vehicle & Heavy Equipment Training and Testing Unit (Tel. Nos. 875-4347/874-1857) to operate specific mobile heavy equipment. (See GI 7.025.)

1.4 Special Crane Operating Procedures

Heavy lifts, critical lifts, and crane personnel work platform operations require special procedures outlined in the Saudi Aramco General Instructions. The Heavy Haul Unit, Transportation Dept., Abqaiq should be contacted and lift plans/work permits submitted. (See GI's 7.027, and 7.028.)

1.5 Effect of Wind Speeds on Crane Operations

When wind velocities are above 32 km/h (20 mph), the rated load and boom lengths shall be reduced according to manufacturer specifications. Wind forces are greater at height by as much as 35% or more. All lifts above ground level, must account for wind force, i.e., side loads, down drafts, etc. as applied to the load and boom. (See TABLES III.1 and III.2.)

1.6 Overhead Power Lines

There is an area surrounding every power line that is referred to as the absolute limit of approach. It is strictly forbidden to move any crane boom or load line or load into this are unless the line has been de-energized or insulated. There are no exceptions. The absolute limit of approach varies according to the following table:

2.1. Safe Working Load (SWL)

Slings and other rigging equipment must be constructed according to a recognized standard.

The safe working load of rigging equipment is the maximum load which the equipment should be subjected to; this load should never be exceeded.

Before use, all new equipment should be subjected to a proof load test by the manufacturer and certified. The safe working load and serial number shall be clearly marked on the sling and the lifting gear, either by tagging, stamping, engraving, or embossing. Riggers shall not use lifting gear unless the safe working load is clearly visible (see Figures III.3 and III.6).

Slings shall not be tagged with an safe working load in the field. Approval by the Inspection Department and subsequent review by the Loss Prevention Department is required.

February 1993 - 2.0 Slings And Lifting Gear Page 276

2.2. Chain Slings

2.2.1 Grades

Only alloy steel chain complying with ASTM A391 shall be used. Other grades are subject to approval by the Saudi Aramco Crane, Communications and Facilities Inspection Unit [CCFIU] (see Figure III.5).

Each grade of chain should be clearly tagged by the manufacturer, and riggers should be trained to look for the safe working load marked on each sling. They shall be forbidden to use any equipment unless the safe working load is clearly visible.

All attached fittings (hooks, rings, etc.,) shall be as prescribed by the manufacturer. Hooks, shackles, and eyebolts shall be equal to or exceed the safe working load of the chain.

2.2.2 Repairs

Modern chains are produced under closely controlled factory conditions using proper heat treatment and testing procedures. On-site welding repairs cannot provide the necessary controlled conditions to safely repair a damaged chain. Damaged chains must be returned to the manufacturer for repair or destroyed. In particular, watch for bent links, cracked welds, and excessive wear.

2.2.3

Logger chains or chains used to secure truck loads shall not be used for rigging.

2.3 Wire Rope Slings

2.3.1

Wire rope is the most common type of sling in use on construction sites. It is essential that each wire rope sling is properly constructed and used. All wire rope slings shall be manufactured, inspected, and load tested by a recognized manufacturer. Homemade wire rope slings shall not be allowed at Saudi Aramco unless they meet all standards and pass inspection by CCFIU.

2.3.2 Damaged slings shall be destroyed if there are:

2.3.2.1

* 10 random broken wires in one lay. * 4 broken wires in one strand of a rope lay. * One broken wire at the fitting.

2.3.2.2

* Severe localized abrasion or scraping.


2.3.2.3

* Kinking, crushing, birdcaging, or any other damage causing distortion.

2.3.2.4

* Evidence of heat damage.

2.3.2.5

* End attachments are cracked, deformed, or excessively worn.

2.3.2.6

* Bent or opened hooks.

2.3.2.7

* Severe corrosion.

2.3.3

Each sling shall bear a permanent manufacturer's identification stating the safe working load (SWL) in tons and serial number. Proof load test and documentation of testing is required from the manufacturer (see Figures III.3 and III.6).

2.3.4

Wire rope clips (bulldog clips or crosby clips) shall not be used to make slings.

2.4 Synthetic Webbing Slings

These are manufactured from woven man-made fiber. Their strength lies in the width of their bearing surface. These slings must not be subjected to point loading, sharp edged objects, and non-vertical lifting (see Figure III.7). Synthetic web slings shall be marked with a stitched in label to show: (a) Name or trademark of manufacturer (b) Rated capacity for each type of hitch (c) Type of material

2.4.1 Removal from Service

Slings which have been damaged or are defective in any way shall be immediately removed from service, cut up and destroyed.

2.4.2 Repaired Slings

The use of repaired slings is prohibited.


2.5 Synthetic and Natural Fiber Rope Slings

2.5.1

Each synthetic and natural fiber rope sling shall be permanently marked to show:

2.5.1.1 Name or trademark of manufacturer

2.5.1.2 Manufacturer's code or stock number

2.5.1.3 Rated loads for the types of hitches used

2.5.1.4 Type of natural or synthetic material

2.5.1.5 Date of manufacture

2.5.2

All associated rigging hardware shall equal or exceed the safe working load rating of the rope sling.

2.5.3

Slings shall be removed from service and destroyed when:

2.5.3.1

* The fibers are cut, badly abraded or seriously worn.

2.5.3.2

* There is considerable filament or fiber breakage (a light fuzzing is acceptable) on the surface.

2.5.3.3

* There are particles of broken filament or fibers inside the rope between strands.

2.5.3.4

* There is other damage visible such as: melting or charring, kinks or hackles, knots, damaged fittings.


2.6 Care of Slings

The following points must be considered in the storage and handling of slings:

2.6.1

Slings will undergo shock loading when a load is suddenly lifted or when the hoisting is abruptly stopped. This can be caused by the sudden application of the crane brake, the jerking of the load by poor operation, or the sling slipping on the load. A shock load can increase the normal working load by as much as five times its value.

2.6.2

As the angle between the legs of a multiple sling increases, the safe working load decreases. The included angle should be no more than 900 and must never exceed 120o under any circumstances (see Figure III.9).

2.6.3

Before storage, chain and wire rope slings should be cleaned, lightly lubricated, and inspected. Slings must be stored in a location where they are not liable to suffer mechanical damage, away from extremes of heat, cold, and especially dampness.

2.6.4

Contractors shall maintain a job site log of slings containing the following information: ID. number; date in service; safe working load as stated in proof load certificate; full details of periodic inspections (see Figure III.13).

2.6.5

All rigging shall be inspected at least every six months per ANSI B30.9, and a Sling Inspection Report shall be completed and filed for review by the Crane Inspector to comply with GI 7.029.

2.7 Hooks

2.7.1

Hooks should be fitted with a safety catch on the hook opening, or should be moused with wire and a shackle used or the hook should be designed so that the slings cannot be displaced (Figure III.11).

2.7.2

Loads should be applied on the hook only in the part designed to take them (i.e. the bend [bow] of the hook). Point loading can result in over stressing the hook causing it to open or break. Therefore, point loading shall not be permitted.


2.7.3

Hooks should be regularly inspected for signs of damage.

2.7.4

The hook shall be removed from service for the following reasons:

1. If there are visible cracks 2. If it is twisted 10o out of place 3. If there is a 15% throat opening beyond the manufacturer's specification

A thorough examination shall be carried out each year by a qualified inspector.

2.8 Spreader Bars

2.8.1

All spreader bars shall be manufactured, tested, and inspected to ANSI B30.20.

2.8.2

Spreader bars shall be permanently identified with the safe working load, manufacturer's name and serial number.

2.8.3

Spreader bars shall be stored away from moisture, and protected from physical damage.

2.9 Eyebolts And Safety Hoist Rings

Sometimes machinery or other equipment is delivered to the site with eyebolts attached as lifting points. For such situations, the design and function of each of the three basic types of eyebolts should be known (see Figure III.10.).

2.9.1

Standard eyebolts are the weakest and are dependable only for vertical lifts.

2.9.2

Shouldered eyebolts can be used at slight angles, but are unsafe at less than 45 degrees with the horizontal.

2.9.3

Safety hoist rings (swivel eyes) are bolted in place with a calibrated torque wrench and maintain maximum capacity at all angles.


2.10 Shackles

Shackles (clevis) are used for making connections in rigging. They should be tested by the manufacturer and marked with the safe working load.

The pins are separate but matched parts of the shackles, so care must be taken to use the correct pin for each shackle. Rebar, mild steel bolts or similar items are not acceptable replacements for shackle pins (see Figure III.12.).

2.11 Rigger

The job of rigger requires thorough training. The man assigned must be well-acquainted with the capabilities of the crane being used, hand signals, the different functions of lifting gear, and the various methods of loading.

3.0 MECHANICAL EQUIPMENT

The widespread use of mechanical equipment in the construction industry improves the quality and efficiency of the work but it can lead to situations which are potentially hazardous.

This section cannot cover all the situations which could arise, but it outlines some of the hazards likely to be encountered from specific items of equipment and their use.

The only safe way of using mechanical equipment is to have properly trained operators, running equipment that is well maintained and carrying out the work for which it was designed.

3.1 Operators

3.1.1 Qualifications

Only trained personnel shall operate any mechanical equipment. Operators shall be trained in the procedures and functions relevant to a specific piece of equipment; they must be fully aware of the capabilities and limitations of the machine and have a knowledge of the day-to-day maintenance that it requires.

It is recommended that contractors train and test all equipment operators and issue them with written authorization specifying the equipment which they are competent to operate.

3.1.2 Licensing Requirements

Operators of mobile heavy equipment must be in possession of a Saudi Arab Government (SAG) license for that particular class of machinery and a Saudi Aramco certificate issued by the Saudi Aramco Heavy Equipment Operator Testing and Training Unit (see GI 7.025).


3.2 Machinery Guards

All moving parts of machinery must be shielded by guards. This is particularly true with gears, pulleys, V-belt drives, fans, and revolving shafts. All of these are present on most of the static equipment used on or around construction sites. Other examples of equipment which must be guarded include cooling fans on compressors and generators, the main drive shafts on pumps and dumpers, and the cable drum on winches and concrete mixers.

Guards must be installed on equipment before it arrives on site and maintained in position at all times while the equipment is operating. Guards removed for routine maintenance or for repair must be replaced before the equipment is returned to service.

3.2.1 Multi-Piece Tire Rims and Locking Rings

As safety equipment like tire cages, restraining bars, racks and clips during tire check-out cannot fully protect employees working on or near the tire repair area, always deflate the tire first before making repairs. Inflate tires inside a strong restraining device (tire cage) by increasing the tire pressure very slowly.

3.3 General Requirements

3.3.1

Before any mechanical equipment is used in a Saudi Aramco restricted area, all required work permits must be obtained.

3.3.2

All machinery should be inspected before being placed in service and at regular intervals thereafter.

3.3.3

Maintenance schedules should be established for each piece of equipment and strictly followed.

3.3.4

No repair, adjustment, or replacement of parts on moving machinery is permitted. Before making any repairs, all equipment must be stopped and deactivated so that it cannot be unintentionally started.

3.3.5

At the start of each shift, the operator must check oil, water, fuel, and hydraulic levels, that all gauges are operating and that the machine is functioning smoothly. Safety equipment (e.g., guards, limit switches, governors) must be checked daily.


3.3.6

Equipment traveling or working on the highway must have lights and reflectors. Park equipment clear of the roadway. If this is not possible, use flashing lights, cones, or other warning devices to alert approaching traffic.

3.3.7

When vehicles are left unattended (even overnight), engines must be stopped, parking brakes applied and the wheels chocked. Blades, scraper bowls, and other hydraulic equipment must be lowered to the ground before the operator leaves the machine. The ignition key should be removed and/or battery cables disconnected to avoid start-up by unauthorized personnel.

3.3.8

Unless otherwise instructed, operators must dismount from machines while maintenance or repair work is being carried out.

3.3.9

Cabs fitted to equipment must give 360o visibility. Cabs must be kept clean and clear of such items as rubbish and loose tools. Windows must be kept clean at all times and should be replaced if the glass becomes pitted, cracked or broken.

3.3.10

Where the operator of a mobile machine cannot see the area all around his machine, an attendant must be in a position to direct and assist the operator.

3.3.11

All equipment must be located so that exhaust fumes will not affect workers in the area. Gasoline-driven equipment shall not be used inside a building or other confined space.

3.4 Compressors

Compressors are one of the most common pieces of equipment used in construction work. They can be used to supply air for portable power tools or to supply air to sustain men working with breathing apparatus in extremely hazardous atmospheres. There is a considerable difference in the quality of the air used for these two functions.

3.4.1

All employees on site must know the dangers of compressed air. Never use compressed air to dust off clothing or machinery. Horseplay with compressed air must be strictly forbidden. When compressed air is used in special cleaning/purging tasks, goggles and full face shield must be worn.


3.4.2

Compressors must be properly designed, inspected, tested and maintained. Relief valves shall be installed in accordance with GI 447.002/3, and the air receiver must be periodically inspected.

3.4.3

Before start up, a daily check should be made of the compressor's pressure relief valve, fuel, oil and water levels and the air reservoir should be drained of trapped water. The operating manual for the particular type of compressor used should be strictly followed.

3.4.4

When compressors supply air for breathing:

1.) The air intake must be located so that it does not draw in exhaust gas. 2.) There must be a filter to remove oil mist. 3.) They must be equipped with an automatic high temperature alarm. 4.) The air must be tested periodically to be certain it is safe to breathe (see

Administration, I.10., 1.3.)

3.5 Concrete Mixers and Batching Plants

A concrete mixer of some type will be used on almost every construction site. The principles of good maintenance and properly trained operators apply equally whether it is only a small mixer for masonry work or a full batching plant with a large capacity cement silo, sand and aggregate bins, and a power shovel.

3.5.1

All chains, gears, and revolving shafts must be guarded.

3.5.2

Safety chains and catches must be operative, and the lifting mechanism must be in good order.

3.5.3

Men must not be allowed to work under or near the loading skip unless it is held in position by a safety chain or catch or positively blocked.

3.5.4

The mixer drum and the area around the machine must be thoroughly cleaned at the end of each day's operation.


3.5.5

Cement bags must not be allowed to accumulate in the mixer area; they should be collected and disposed of at regular intervals during the day.

3.5.6

A hooped access ladder must be firmly attached to silos for access to the top manhole. Men must not be allowed to work inside the silo unless they are wearing a safety belt with a lifeline and an attendant is posted outside ready to assist in case of emergency.

3.5.7

The approach to the sand and aggregate bins should be barricaded, and the barricades should only be removed to allow access for vehicles delivering material.

3.5.8

Personal protective equipment such as respirators, ear muffs, and goggles shall be worn. Loose fitting clothes shall not be worn around moving machinery.

3.5.9

Lockout and tag system is required in batching plants to ensure the safety of repair and/or maintenance personnel. This is a means to disable process/mechanical electrical 'control' equipment during repairs and maintenance. Lockout and tag system rules must be posted in a conspicuous location throughout the plant and workers must be thoroughly trained in the lockout/tag procedures.

3.6 Dumpers and Dump Trucks

Dumpers and dump trucks, commonly used for construction work, often travel on the public highway. Therefore it is essential that they be properly maintained.

3.6.1

The latch on dumper skips must be in good working order, and the release mechanism should function smoothly.

3.6.2

Dumpers are not designed to carry passengers. It must be strictly forbidden for employees to ride in the skip or on the engine cover.

3.6.3

When repairs or maintenance are being carried out on a hydraulically operated dump truck, the dump body should be fully lowered. If it is necessary to have it


in the raised position, it must be blocked. Do not rely on the hydraulic ram to support the raised body for an extended period.

3.6.4

All vehicles with cabs shall be equipped with windshields and powered wipers. Cracked or broken windshields or windows shall be replaced. All cab glass shall be safety glass or equivalent.

3.7 Excavators

Excavations are carried out using very specialized equipment which roughly falls into two categories: 1) fixed position machines, and 2) moving machines.

The choice of equipment to be used is determined by the size of the project, topography, volume of earth to be hauled out and many other factors. Fixed position machines include, but are not limited to, face shovels, backhoes, draglines and grabs. The "fixed" excavator loosens the soil and loads from a stationary position. They are useful to perform specific excavation tasks at a single location. Their loss of mobility is compensated by the fact that greater force can be applied at the excavation face. "Moving" machines include, but are not limited to, bulldozers, loaders, scrapers, graders and trenching machines. They remove, transport and deposit excavated material all in one cycle of operation. They are used in applications where large volumes of earth need to be moved over uneven ground. In this process, they also help to level the ground over which they operate. (Also see General And Civil, II.2 of this manual.)

3.7.1

The excavation work permit may require that underground pipelines or cables be located by manual digging. The permit must be counter-signed by the Power Distribution Department (PDD) and the area Utilities Services Department.

3.7.2

Operators of excavators must possess a valid Saudi Arab Government license for the machine and a valid Saudi Aramco certificate issued by the Saudi Aramco Heavy Equipment Operator Testing Unit.

3.7.3

Outriggers must be fully extended when operating a mechanical excavator so fitted.

3.7.4

An attendant must be appointed and be available at all times during excavation to assist and guide the operator.

3.7.5

Excavators with a swinging motion must have a clearance of at least 0.6 meter (2 feet) from any fixed object.


3.7.6

Booms on excavators must be latched before travel.

3.7.7

Do not excavate closer than 10 feet to the nearest pipeline or other equipment in place.

3.8 Fork Lift Trucks

Fork lift trucks are designed to operate on firm, level ground. This type of equipment has a limited use in construction operations. They are, however, sometimes used in materials handling yards and for placing loads where there are firm ground conditions. Operators of fork lift trucks must have a valid Saudi Arab Government heavy equipment license and a valid Saudi Aramco certificate.

3.8.1

It is essential that drivers be fully trained and experienced. They must be able to manipulate loads smoothly and efficiently.

3.8.2

A specific course of instruction should be established for fork lift drivers. They should not be allowed to use the vehicles on site until they have taken the course.

3.8.3

Special equipment fitted to the truck, in addition to or in place of the forks, must be designed for the specific machine.

3.8.4

The truck shall be equipped with overhead protection.

3.8.5

When traveling with a load on the forks, the forks should be as low as possible to maintain stability.

3.8.6

If the load being carried obstructs the operator's forward view, he should travel in reverse.


3.8.7

Operators, loaders, helpers and other workers should never place any part of their bodies between the mast uprights, cross members, or other moving parts of the fork lift truck. Stay well within limits of the truck body or cab.

3.9 Generators

A competent electrician shall be available to ensure that electrical connections are properly made. The operator should be responsible only for the mechanical function of the machine.

3.9.1

All pulleys, belts, and fans must be totally enclosed or otherwise guarded.

3.9.2

The side panels to the engine cover are designed to give access to the machinery for maintenance or repair. They must be closed at all times when the engine is running.

3.9.3

The machine must be properly grounded before each use.

3.9.4 Fire Prevention Guide for Portable Generators

The following is a typical check list of the major items to look for. There may be other potential fire hazards not listed, therefore a thorough inspection must be made.

• Repair all fuel leaks. • Check hose and pipe connections for wear and cracks. • Clean up all combustible trash around the generator. • Clean up all fuel spills and place clean sand around area when required. • Sheds constructed of combustible materials placed around generators and

wooden base frames are prohibited. • Exhaust piping system shall be kept away from work areas and combustible

materials. • Generator sets shall be located at least 50 feet from buildings or materials

that may catch fire. • Inspect all wiring for damage or improper splices/repairs. • Electrically ground all generator sets (system and frame ground). • Fire extinguishers must be readily accessible. One CO2 extinguisher for the

generator and a dry chemical extinguisher for the engine drive is recommended.

• Conduct daily inspections of all generator sets using this guide.


3.10 Graders, Dozers, Scrapers, Loaders And Miniloaders

Heavy earth moving equipment only allows the operator a limited view of the immediate area. It is, therefore, essential that a banksman be appointed to warn the operator of hazards that cannot be seen from the operator's position.

This equipment shall be equipped with rollover protection. A valid Saudi Arab Government heavy equipment license and a valid Saudi Aramco certificate issued by the Saudi Aramco Heavy Equipment Operator Testing Unit are required for each operator of such equipment.

3.10.1

Before moving his machine, the driver must walk around it to see that the area is clear.

3.10.2

Men must not be allowed to sit or lie in the area around the machine.

3.10.3

The engine shall not be left running when the driver is not at the controls. Before leaving his machine, a driver must shut off the engine and remove the ignition key.

3.10.4

Blades, scraper bowls, etc. must be lowered to the ground before the driver leaves his unit. The wheels should be properly chocked.

3.10.5

If there is work to be done underneath such hydraulic equipment, the equipment must be blocked in position.

3.11 Woodworking Machinery

Only fully trained operators may be allowed to use woodworking machinery. This machinery is inherently dangerous since the hazardous parts, knives, blades, etc., cannot be fully enclosed. Only that part of the blade necessary to carry out the work shall be exposed at any one time.

3.11.1

The area around saws, planers, and routers must be barricaded and only authorized and trained personnel allowed within the barricaded area.


3.11.2

The ground around such machinery must be kept clear of off-cuts and other tripping hazards.

3.11.3

Machinery should be securely anchored to prevent movement during use. (See General And Civil, II of this manual.)

February 1993 - 4.0 Materials Handling Page 298

4.0 MATERIALS HANDLING

Materials handling forms a large part of construction work. How construction materials are handled can have a considerable effect on the efficiency of production and on the safety record of the site. Because of the temporary nature of site work and the frequent change of the work place, it is not possible to mechanize material handling to the same extent as it would be in a more stable operation. However, there are many areas in which labor intensive, inefficient, costly, and frequently dangerous, manual material handling work can be replaced by the use of machines.



GI 355.001 Identifying, Ordering, Receiving, Storing, Issuing And Disposing Of Hazardous Materials

GI 1130.013 Vehicle Loading

GI 1131.165 Use of Trailer Brakes

GI 1131.921 Use of Trailer Safety Chains

4.1 Planning

Successful mechanization of material handling requires that the correct machines be available and properly used. The storage and movement of the various materials must be carefully arranged to make optimum use of the machines so that efficient service can be provided and ensure that all vehicle, crane and heavy equipment operators hold current Saudi Arab Government License and Saudi Aramco Certification where required.

Planning for materials handling operations begins as the production schedule is being drawn. Ensure that the layout of storage areas provides for adequate access for necessary mechanical equipment.

4.1.1

Selection of the storage area should be made with due consideration for drainage and protection from rain and sandstorms (see Figure III.13 Typical Construction Materials Store Yard).

4.1.2

Open storage areas should be planned to minimize the reversing and maneuvering of trucks especially into and out of confined areas.

4.1.3

Access ways must be wide enough to allow for the passage of fire trucks. Fire fighting equipment should be located throughout the area. Contact the Fire Prevention Group of Loss Prevention for information (see Figure III.13 Typical Construction Materials Store Yard).


4.1.4

Cribbing timber, racks, or pallets should be used to ensure that all materials are stored off the ground.

4.1.5

Protection should be provided for materials such as cement, insulation, and other bulk material which could be damaged by moisture.

4.1.6

All machinery, equipment, and valves should be maintained fully assembled and securely closed. All machined surfaces must be covered and fully protected from exposure to the weather.

4.1.7

The quantity of material on site at any one time must be restricted to a minimum stock. Flammable stores shall be kept separated. Such a policy should greatly reduce losses due to pilferage or damage (see Figure III.13 Typical Construction Materials Store Yard).

Once these factors have been established, the staffing of the storage areas can then be considered.

4.1.8

On larger projects, the movement of materials could justify the employment of a loading and unloading gang, whereas small jobs would probably need only one man assigned to this responsibility.

4.1.9

Routinely, on most sites, there should be a man appointed as a materials controller responsible for materials from the planning stage through to the final unloading, storage, and distribution stage.

4.2 Machine Transport

A wide variety of mechanical equipment is available for transporting and distributing materials on and around a job site. They range from simple equipment such as a dumper or a tractor and trailer to more sophisticated equipment such as a concrete pump or a large crane.

4.2.1 Dumpers

Dumpers are one of the most commonly used pieces of construction equipment and have proved very useful in transporting concrete and other small loads around site. Unfortunately they are also a common source of injuries and damage.


Dumper drivers must be properly trained and experienced and must hold a current Saudi Arab Government license. The equipment is designed for the movement of material only. Passengers must not be allowed to travel in the skip or anywhere else on the machine. Dumpers must be regularly maintained with particular attention to brakes, steering, and skip release mechanism. If they are to be used for towing, a proper towing eye with a shackle or pin must be provided.

4.2.2 Tractors and Trailers

Tractors and trailers are useful for moving larger loads around the site. In addition to the normal precaution of good maintenance, it is essential that safety chains or wire ropes be fitted between the tractor and trailer so that if the towing connection should break or become separated for some reason, the trailer can still be brought to a controlled stop by the tractor. Trailer and its load shall not exceed the towing capacity of the tractor and shall be fitted with an independent braking system if it is designed to carry more than 9,072 kilograms (20,000 pounds). Trailers used for carrying pipes should be fitted with side stops, and loads must be securely tied down before being transported.

4.2.3 Conveyor Belts and Monorails

Conveyor belts and monorails are occasionally used for transporting concrete, sand, or aggregate on site. They require a complete maintenance program. Because of the many problems associated with them, thorough consideration must be given to their use. All pulleys, rollers, gears and pinch points shall be guarded. On/off switches shall be clearly marked and readily accessible.

4.2.4 Concrete Pumps

Concrete pumps are used for the placement of concrete in difficult situations. They have the advantage of being able to move large amounts of concrete very speedily to the area where it is required. The operation of this equipment demands specialized knowledge of concrete technology; however, placing concrete by this method can significantly reduce the number of dumpers employed or the crane usage time expended on a civil engineering contract.

4.3 Site Stores

For small or valuable materials which cannot be conveniently stored in outside areas, it is essential that an indoor stores shed, under the control of a responsible person, be established on site. Because of the nature of the materials stored in such an area, the main considerations must be security and fire prevention.

The issuing and receiving of stores must be under the control of a responsible person. Adequate fire fighting equipment must be readily available in the area. Materials should be stored on shelving or with small items such as nuts and bolts, etc. in bins suitably marked with the contents. The safe loads allowed on racks and the maximu m stack heights should be established. All hazardous material, such as paints, fuels, chemicals, etc., should be separated and stored in an isolated flammable storage area (see Appendix C). Notices warning of the dangers associated with these materials should be posted in the hazard area.


4.4 Manual Handling

There are many areas of construction work where mechanization cannot take the place of sheer muscle, and it is in such areas that the majority of injuries occur. The inevitable results of lifting incorrectly are strained backs, slipped discs, sprains and strains, and a complexity of internal injuries.

It is, therefore, essential that workers be trained in the correct methods of manual handling. Safe lifting can only be carried out by the proper use of the right muscles. Back and abdominal muscles are weak, while the leg and thigh muscles are strong. The spine has a natural and comfortable shape when a man is standing upright; however, if he bends, the spine arches and becomes weaker. If the spine can be kept in a straight position when lifting, the strain of the lift goes to the strong muscles of the leg and thigh and loads can be lifted safely, with much less physical effort. This is the basic principle of manual handling.

4.4.1

There are four significant points in a proper lift:

1. Grip: A good grip makes maximum use of the palm of the hand, the ball of the thumb, and base of the fingers.

2. Back: The back must be kept straight to maintain its most natural and strongest position. This means that the knees and ankles must be bent and the chin kept well into the chest. The body must be positioned as close to the load as possible so as to act as a counterweight.

3. Feet: The feet should be apart the width of the hips with one foot slightly in front of the other so that a natural lead off is obtained.

4. Arms: The arms must be kept as close as possible to the body.

4.4.2

The important factor in manual handling is that a man should know his capabilities and ask for assistance with loads beyond his capabilities. In dual lifting, partners should be approximately the same height and weight so that the load does not become unevenly distributed.

4.4.3

Loads, even when properly lifted, can slip. The man lifting must be prepared for such a possibility and wear the proper protective equipment. Safety footwear is mandatory to protect feet and gloves should be worn to protect hands from laceration or splinters and to give some protection if the fingers are trapped between the load and the other surfaces.


FIGURE III.13: TYPICAL CONSTRUCTION MATERIALS STORE YARD

1.0 ELECTRICITY

The human senses (smell, taste, hearing, etc.) do not provide a warning of an electrical hazard. The great majority of electrical accidents result in burns. Fire and explosion from sparks in flammable atmospheres can and does lead to loss of life and serious damage to property. All electrical installations, no matter what voltages are used, should always be treated with great caution.

February 1993 - 1.0 Electricity Page 307

1.1 Voltage

The severity of electric shock is not entirely dependent upon the voltage of the power source. The ratio of the voltage to resistance determines the current that will flow through the body and the resulting injury.

In terms of a formula this ratio is:

Current through the body = Voltage applied across the body Resistance of the body + contact resistance

The hazard is greater if working conditions are wet or if the worker perspires freely. This produces a combination of wet skin and body salt which provides low resistance to current flow.

1.2 Temporary Installations

Distribution of electricity on a construction site is different from a permanent installation. As construction work proceeds, the type of equipment in use changes. From excavation to completion, there is a constant need for convenient means of connecting equipment. This requires a variety of voltages, phases, and current in different places at different times. Load requirements will vary considerably. All temporary electrical systems shall conform to the National Electrical Code.

1.2.1

The contractor is responsible for the temporary electric supply system on a construction site and the safety measures associated with the National Electrical Code.

1.2.2

Cables on site are subject to rough treatment. Special care should be taken to ensure that the grounding conductor remains intact. If the conducting wire breaks, the supply will not be interrupted under a ground fault condition and the system will no longer be safe. Only UL, FM or other recognized testing lab approved extension cords bearing appropriate lab trademarks shall be used. Damaged or spliced cords are not acceptable to Saudi Aramco.

1.2.3

Special care shall be taken to ensure that the correct fuse or breaker ratings are strictly enforced and that the Ground-Fault Circuit Interrupters (GFCIs) are installed properly on all circuits.

1.2.4

All installation work must be carried out by qualified, experienced electricians. Before connecting temporary electrical installations to existing installations, prior approval must be obtained from the Saudi Aramco proponent department.


This is to ensure that no overloading of electrical devices will occur and system protection will not be compromised.

1.2.5

A competent person must be made directly responsible for the overall safety of the installation. Its general usage, its maintenance, and any alterations and extensions to the system should be under his control. He must be at the site whenever work is being done. Before any part of a newly installed electrical system or its equipment is energized, it must be thoroughly tested. Safety can be ensured by regular inspection and maintenance.

1.3 Hand Tools and Lighting

1.3.1

Many injuries, fires, and explosions have resulted when extension lights with defective cords or fittings have been used or when bulbs have been broken, exposing the live filament wire to an explosive atmosphere. All electrically operated tools shall be rated and used at a voltage not exceeding 125V. The use of 220V is prohibited.

1.3.2

Defective extension lights and electric hand tools shall be repaired or replaced. A defective electrical tool or cord can cause burns, falls as a result of sudden shocks, or even fatalities.

1.3.3

Portable electric tools, extension lights and cords should be inspected each time they are issued and returned. This should be part of a tool store procedure. Frequent random checks should be made where those tools, lights and plugs are being used on site.

Portable hand lamps shall comply with the following:

(1) Metal shell, paper-lined lamp holders shall not be used.

(2) Hand lamps shall be equipped with insulated handle.

(3) Substantial lamp guard shall be attached to the handle or holder. Metallic lamp guards shall be grounded. Three-wire power cords with grounding conductor shall be used.

1.3.4

Failure of electrical equipment, because of misuse, is a frequent cause of shock. Workers are prone to abuse extension cords by pulling them over sharp metal objects, hanging them across equipment, kicking them, or letting them be run over


by industrial equipment. They often strain the cords during use, causing the plug and fixture to part and expose live wires.

1.3.5

Many accidents occur when lower volt equipment is plugged into higher volt systems. Before any portable tool or extension light is plugged in, the voltage required for the tool or light must be the same as the power source, and the plugs must be checked for damage.

1.3.6

The importance of grounding all portable tools and lights cannot be emphasized too strongly. All non-current carrying metal parts of any electrical equipment must be properly grounded. This will reduce the electrical shock hazard.

1.3.7

In hazardous areas, more stringent rules apply as to the type of equipment which may be used. Explosion proof light fittings for extension lights is one example. As with all work carried out on Saudi Aramco installations, Work Permits must be obtained and the type of equipment to be used discussed and agreed upon before the permit is issued.

1.3.8 General Precautions:

Only qualified electricians should make repairs and carry out maintenance checks. All extension lights must be fitted with protective guards, so if accidentally dropped, the lamp remains intact. Up to a 120 volt maximum rated AC portable lighting system may be used for illuminating inside confined spaces and vessels, provided it is protected by an externally located ground fault circuit interrupter and also meets the provisions of GI 520.001 Section 5.5.5.1 and 520.001-4 (Supplement 4) - "Confined Space Entry Procedure" (Abqaiq Plants).

1.3.9

Ground fault circuit interrupters shall be used on all electrical circuits including portable power electrical supplies (see NFPA Handbook of the National Electric Safety Code, Section 305-b for GFCIs) on temporary wiring.

1.3.10

The National Electric Safety Code defines requirements for the construction and use of portable extension and electric cords in industrial service. This code shall be followed by construction groups.

1.4 Work on Live Equipment

1.4.1

Whenever workmen are required to work on energized equipment, the job must be planned thoroughly and the workmen should proceed with caution.


Before any work on live equipment starts, there must be a thorough knowledge of the work involved, personal protective equipment must be available, and all necessary work permits must be obtained.

1.4.2

Employees must never work alone on live equipment. In addition to the man doing the job, there must be another electrician standing by. A foreman or supervisor should also be in attendance while this work is being carried out, and he must know how to isolate the equipment.

1.4.3

Before starting a job, the exact voltages should be known. This is important as it determines the type of personal protection required for the work and the procedures established in the work permit. If there is any doubt about voltages, a check must be made before the work is started.

1.4.4

Work platforms and equipment used near energized equipment shall be properly grounded.

1.4.5

Work on live equipment can be as safe as work on isolated equipment if the following are observed:

1 There must be a thorough knowledge of the equipment and the job to be done.

2 If there is any doubt, the advice of the supervisor or responsible person should be sought.

3 The work must be correctly planned before starting. 4 Protective equipment must be used correctly.

1.5 Overhead and Underground Cables

On any construction site, power supplies may have already been installed below ground or overhead.

Contact should be made with the appropriate Saudi Aramco department at the planning stage of the job to determine the work permit requirements, route and depth of any underground cables and the recommended safe clearances. If re-routing existing cables is necessary, this should be done before the main contract starts.

1.5.1 Overhead Lines (Figure IV.1)

High voltage or overhead lines are usually uninsulated. Therefore, any kind of metallic object coming near or in contact with them can cause a hazardous situation. High voltage can easily arc across a considerable distance. (See OSHA 29 CFR 1926 Subpart N.)


1.5.2 The Contractor Should Arrange for Power Lines to be:

1 Re-routed clear of all construction work or placed underground if possible. 2 Made "dead", grounded, and certified as such by Saudi Aramco. 3 Protected by barriers and timber or wire "goal-posts", so that no part of any

mobile crane, earth moving equipment, etc. can approach the live cable. Clearance distances should be agreed upon with Saudi Aramco. Access below the powerlines shall be restricted by barriers to where the "goal-posts" are located (see Figure IV.1).

The need for caution in working with overhead lines cannot be over-emphasized. High voltage overhead lines have been mistaken for telephone cables.

It should never be assumed that there is enough clearance; it should always be proved. It should never be assumed that a cable or line is "dead"; it should always be checked.

1.5.2.1 Spacing Between Powerlines and Pipelines

Special precautions are required during installation, operation or maintenance of above grade or below grade onshore pipelines. (See SAES-B-064.)

1.5.3 Underground Cables

Normal depth of underground cables varies between 46 centimeters (18 inches) and 0.9 meter (3 feet). (Changes in ground level, due to the work, can mean that the "as built" depth is no longer correct). No mechanical excavations should be started before test trenches have been dug by hand and cable locations established. Unless cables have been laid very deep, heavy vehicles should not be allowed to pass over them.

Underground cables, exposed during excavation work should be assumed to be energized and not repositioned or moved until certified to be de-energized. Exposed buried cables in open trenches should be properly supported and the area barricaded.

Accidental damage to any cable exposed during excavation shall be immediately reported to Saudi Aramco. The area must be barricaded until the damaged cable has been made safe.

1.6 Overhead Power Transmission and Distribution

The standards given in this section provide minimum requirements for safety and health during construction.

1.6.1 Initial Inspections, Tests, or Determinations

Existing conditions shall be determined before starting work, by an inspection or a test. Such conditions shall include, but not be limited to, energized lines and


equipment, condition of poles, and the location of circuits and equipment, including power and communication lines.

Electrical equipment and lines shall be considered energized until determined to be de-energized by testing and grounding.

Operating voltage of equipment and lines shall be determined before working on or near energized parts.

1.6.2 De-energizing Lines and Equipment

The procedures outlined in GI 2.100 and GI 6.012 shall be followed, and all circuits will be identified, tagged, locked, and tested.

Equipment shall be checked for potential and protective grounds shall be applied.

Guards or barriers shall be erected as necessary near to adjacent energized lines.

When more than one independent crew needs to work on the same line or equipment at the same time, a separate "clearance" shall be given to each crew by the Saudi Aramco Power Dispatcher, and a prominent tag and lock for each such independent crew shall be placed on the line or equipment by the designated crew leader.

Upon completion of work on de-energized lines or equipment, the crew leader shall determine that all members in his crew are clear and that protective grounds installed by his crew have been removed. He shall release his clearance to Saudi Aramco.

1.6.3 Emergency Procedures and First Aid

The Contractor shall provide training or require that his employees are knowledgeable and proficient in the following:

1 Procedures involving emergency situations; 2 First-aid fundamentals including cardiopulmonary resuscitation; and 3 Remote field crews shall have an employee certified in First-Aid.

1.6.4 Night Work

When working at night, spotlights or portable lights for emergency lighting shall be provided as needed to perform the work safely.

1.6.5 Work Near/Over Water

When crews are engaged in work over or near water and when danger of drowning exists, suitable protection such as buoyant work vests shall be worn. Life rings, ropes and at least one skiff shall be provided.


1.6.6 Hydraulic Fluids

All hydraulic fluids used for the insulated sections of derrick trucks, aerial lifts, and hydraulic tools which are used on or around energized lines and equipment shall be of the insulating type.

1.6.7 Live-Line Tools (Hot Sticks)

Only live-line tool poles having a manufacturer's certification meeting the following requirements shall be used:

1 100,000 volts per foot of length for 5 minutes when the tool is made of fiberglass, or

2 75,000 volts per foot of length for 3 minutes when the tool is made of wood; or

All live-line tools shall be visually inspected and wiped clean before use each day. Tools with any hazardous defect shall be removed from service.

1.6.8 Material Handling

An employee shall be utilized to determine that required clearance is maintained in moving equipment under or near energized lines.


1.6.10.2 Stringing/Removing De-energized Conductors

When stringing or removing de-energized conductors, the provisions of the following paragraphs shall be complied with.

Prior to stringing operations, a briefing shall be held setting forth the plan of operation and specifying the type of equipment to be used, grounding devices and procedures to be followed, crossover methods to be employed, and the clearance authorization required.

Where there is a possibility of the conductor accidentally contacting an energized circuit or receiving a dangerous induced voltage buildup, to further protect the employee from the hazards of the conductor, the conductor being installed or removed shall be grounded.

When the existing line has been de-energized, proper clearance authorization shall be secured and the line grounded on both sides of the crossover, or the line being strung or removed shall be worked on as if energized.

When crossing over energized conductors in excess of 600 volts, rope nets or guard structures shall be installed unless provision is made to isolate or insulate the workman or the energized conductor. Where practical the automatic re-closing feature of the circuit interrupting device shall be made inoperative. In addition, the line being strung shall be grounded on either side of the crossover or and worked on as if energized.

Conductors being strung in or removed shall be kept under positive control by the use of adequate tension reels, guard structures, tielines, or other means to prevent accidental contact with energized circuits.

Guard structure members shall be sound and of adequate dimension and strength, and adequately supported.

Anchors, riggings, and hoists shall be of ample capacity to prevent loss of the lines.

The manufacturer's load rating shall not be exceeded for stringing lines, pulling lines, sock connections, and all load-bearing hardware and accessories.

Pulling lines and accessories shall be inspected regularly and replaced or repaired when damaged or when dependability is doubtful.


Conductor grips shall not be used on wire rope unless designed for this application.

While the conductor or pulling line is being pulled (in motion) employees shall not be permitted directly under overhead operations, nor shall any employee be permitted on the crossarm.

A transmission clipping crew shall have a minimum of two structures clipped in between the crew and the conductor being sagged. When working on bare conductors, clipping and tying crews shall work between grounds at all times. The grounds shall remain intact until the conductors are clipped in, except on dead end structures.

Except during emergency restoration procedures, work from structures shall be discontinued when adverse weather (such as high wind or ice on structures) makes the work hazardous.

Stringing and clipping operations shall be discontinued during electrical storms.

Reel handling equipment, including pulling and braking machines, shall have ample capacity, operate smo othly, and be leveled and aligned in accordance with the manufacturer's operating instructions.

Reliable communications between the reel tender and pulling rig operator shall be provided.

Each pull shall be snubbed or dead ended at both ends before subsequent pulls.

1.6.10.3 Stringing Adjacent to Energized Lines

Prior to stringing parallel to an existing energized transmission line, it shall be determined whether dangerous induced voltage buildups will occur in the system, particularly during switching and ground fault conditions.

When stringing adjacent to energized lines, the tension stringing method or other methods which preclude unintentional contact between the lines being pulled and any employee shall be used.

All pulling and tensioning equipment shall be isolated, insulated, or effectively grounded.

A ground shall be installed between the tensioning reel setup and the first structure in order to ground each bare conductor, sub-conductor, and overhead ground conductor during stringing operations.

During stringing operations, each bare conductor, sub-conductor, and overhead ground conductor shall be grounded at the first tower adjacent to both the tensioning and pulling setup and in increments


so that no point is more than 3.218 kilometers (two miles) from a ground.

• The grounds shall be left in place until conductor installation is completed.

• Such grounds shall be removed at the last phase of aerial cleanup.

• Except for moving type grounds, the grounds shall be placed and removed with a hot stick.

• Conductors, sub-conductors, and overhead ground conductors shall be grounded at all dead-end or catch-off points.

A ground shall be located at each side and within 3.2 meters (10 feet) of working areas where conductors, or overhead ground conductors are being spliced at ground level. The two ends to be spliced shall be bonded to each other. It is recommended that splicing be carried out on either an insulated platform or on a conductive metallic grounding mat bonded to both grounds. When a grounding mat is used, it is recommended that the grounding mat be roped off and an insulated walkway provided for access to the mat. (See Power Distribution Instruction No. 50.)

All conductors, sub-conductors, and overhead ground conductors shall be bonded to the tower at any isolated tower where it may be necessary to complete work on the transmission line.

• Work on dead-end towers shall require grounding on all de-energized lines.

• Grounds may be removed as soon as the work is completed, provided that the line is not left open circuited at the isolated tower at which work is being completed.

When performing work from the structures, clipping crews and all others working on conductors, sub-conductors, or overhead ground conductors shall be protected by individual grounds installed at every work location.

1.6.11 Underground Lines

Warning signs shall be promptly placed when covers of manholes, hand holes, or vaults are removed.

Before an employee enters a street opening, such as a manhole or an unvented vault, it shall be promptly protected with a barrier, temporary cover, or other suitable guard.

When work is to be performed in a manhole or unvented vault, GI 2.100, Work Permit System, shall be enforced.


• No entry shall be permitted unless forced ventilation is provided or the atmosphere is found to be safe by testing for oxygen deficiency and the presence of explosive gases or fumes.

• Where unsafe conditions are detected, by testing or other means, the work shall be ventilated and otherwise made safe before entry.

• Provisions shall be made for an adequate continuous supply of air.

1.6.11.1 Work in Manholes

While work is being performed in manholes, an employee shall be available in the immediate vicinity to render emergency assistance as required. This shall not preclude the employee in the immediate vicinity from occasionally entering a manhole to provide assistance, other than for emergencies. This requirement does not preclude a qualified employee, working alone, from entering for brief periods of time, a manhole where energized cables or equipment are in service, for the purpose of inspection, housekeeping, taking readings, or similar work if such work can be performed safely. However, someone on the surface must be aware of this type of entry and know the expected duration of the task.

Before entering or using open flames in a manhole excavation in an area where combustible gases or liquids may be present, such as near a gasoline service station, GOSP, refinery, etc., the atmosphere of the manhole or excavation shall be tested and found safe or cleared of the combustible gases or liquids (See GI 2.100).

1.6.11.2 Trenching and Excavating

During excavation or trenching, in order to prevent the exposure of employees to the hazards created by damage to dangerous underground facilities, efforts shall be made to determine the location of such facilities and work in accordance with GI 2.100, Work Permit System.

When underground facilities are exposed (electric, gas, water, telephone, etc.) they shall be protected as necessary to avoid damage.

When multiple cables exist in an excavation, the cable to be worked on shall be identified by electrical means unless its identity is obvious by reason of distinctive appearance.

Before cutting into a cable or opening a splice, the cable shall be identified and verified by the proponent department.

When working on buried cable or on cable in manholes, metallic sheath continuity shall be maintained by bonding across the opening or by equivalent means.


1.6.12 Construction in Energized Substations

When construction work is performed in an energized substation, authorization shall be obtained from the local power service dispatcher and a work permit shall be issued. (See GI 2.100)

When work is to be done in an energized substation, safety precautions shall be detailed in the work permit (See GI 2.100).

Extreme caution shall be exercised in the handling of busbars, tower steel, materials, and equipment in the vicinity of energized facilities.

1.6.12.1 Barricades and Barriers

Barricades or barriers shall be installed to prevent accidental contact with energized lines or equipment.

Signs indicating the hazard shall be posted near the barricade or barrier.

1.6.12.2 Control Panels

Work on or adjacent to energized control panels shall be performed by designated employees.

Precaution shall be taken to prevent accidental operation of relays or other protective devices due to jarring, vibration, or improper wiring.

1.6.12.3 Mechanized Equipment

Use of vehicles, gin poles, cranes, and other equipment in restricted or hazardous areas shall at all times be controlled by designated employees.

All mobile cranes and derricks shall be effectively grounded when being moved or operated in close proximity to energized lines or equipment, or the equipment shall be considered energized. (See OSHA 29 CFR 1926 Subpart N.)

Fenders shall not be required for low-boys used for transporting large electrical equipment, transformers or breakers.

1.6.12.4 Substation Fences

When a substation fence must be expanded or removed for construction purposes, a temporary fence affording similar protection, when the site is unattended, shall be provided. Adequate bonding and grounding interconnections shall be maintained between temporary fence and permanent fence.


All gates to all unattended substations shall be locked, except when work is in progress.

1.7 Electric Shock

Speed is essential in dealing with any electrical accident. A copy of "The Treatment for Electric Shock" placard in Arabic and English should be prominently displayed so that everyone knows what to do in an emergency. Employees will be trained in First Aid and cardiopulmonary resuscitation (CPR).

In brief, the sequence for dealing with an electrical accident is:

1 If at all possible, switch off the power supply. If this is not instantly possible, release the victim from contact with the conductor by using dry gloves, dry blanket, dry wood, dry clothing, rubber sheets, or properly insulated equipment.

2 If breathing has stopped, begin CPR and continue as necessary. 3 Call for first aid assistance, a doctor, and an ambulance. The Saudi Aramco emergency

number is 110.


FIGURE IV.1: TEMPORARY CROSSING FOR CONSTRUCTION EQUIPMENT

Overhead power lines are usually uninsulated and any kind of metallic object coming near or in contact with them can cause a hazardous situation. High voltage can easily arc across considerable distance. Overhead lines should therefore be re-routed, "made dead" or protected by timber "goal posts" and barriers. Clearance distances should be agreed upon with Saudi Aramco before work starts.

2.0 IONIZING RADIATION

Ionizing industrial radiation, such as x-rays generated by equipment or gamma rays emitted spontaneously by radioactive materials, are widely used in industry for non-destructive testing, e.g., testing of welds in pipes and pressure vessels, without damaging the material. The material tested does not retain any radioactivity when testing is completed.

For all practical purposes, the radiation produced by x-ray equipment or emitted by radioactive sources are the same. X-rays and gamma rays both have properties which should be understood. Even though they penetrate the body, they cannot be perceived by any of our five senses; they can be absorbed and scattered by matter; they travel in straight lines at the speed of light; they ionize gases; they affect photographic emulsions; and by far the most important, they can be harmful to the living cells of the body.

AB-36895 Radiation Warning Sign

2.1 Methods of Protection Against Radiation

Distance, time, and shielding are the usual methods of reducing radiation exposure.

2.1.1 Distance

Distance is an effective method of protection because gamma and x-rays obey the inverse square law, that is, the radiation intensity decreases with the inverse square of the distance. Conversely, dose rates at close distances can be extremely high, even for low activity sources. It is essential, therefore, that unshielded sources are kept at a sufficient distance from personnel so as not to pose a health hazard to them.

2.1.2 Time

Time is a useful method of protection because high dose rates can be accepted over very short periods of time. However, the cumulative dose must remain at acceptable limits given in GI 150.003-2.

February 1993 - 2.0 Ionizing Radiation Page 326

2.1.3 Shielding

To lessen harmful radiation, materials of high density, such as lead, depleted uranium, or tungsten, are used to absorb emitted radiation.

In the use of x-ray equipment, precautions against emitted radiation are necessary until the electric power is turned off and locked out. On the other hand, radioactive materials constantly emit radiation and cannot be switched off. Consequently, to absorb unwanted radiation and facilitate handling, sealed sources are housed in shielded containers or bunkers.

2.2 Classification of Personnel and Exposure Limits

In order to control human exposure to industrial radiation, all employees and contractors are classified as either radiation workers or non-radiation workers according to their training and need to use radiation sources. Classification does not guarantee safety; safety procedures and adequate equipment must be used at all times.

2.2.1 Radiation Workers

A radiation worker is an occupationally exposed person or employee whose job involves routine use of ionizing radiation and who has reasonable chance of being exposed to radiation from a radioactive source.

Radiation workers are further categorized as Competent Persons or Radiographers. Competent Persons do not normally use radiation sources, but by training and experience are capable of supervising both routine operations and emergency situations involving radiation. Radiographers are expected to safely use radiation sources in the course of their work and must be in possession of a valid "Saudi Aramco Permit to Use Material/Equipment Producing Ionizing Radiation" before they can work with a radioactive source.

Radiographers must wear two personal dosimeters when working with radiation, a direct-reading pocket dosimeter and an integrating permanent dosimeter (film badge or thermoluminiscent dosimeter [TLD]).

2.2.2 Non-Radiation Workers

Non-radiation workers should not receive more than those dose limits given in GI 150.003-2.

2.2.3 Exposure Limits

Radiation doses to workers should always be kept as low as reasonably achievable (ALARA). Under no circumstances shall the doses exceed those limits given in GI 150.003-2 for occupational or non-occupational people.

Special controls (see GI 150.003-2) are imposed on persons who are, or are capable of being, pregnant. No occupational exposure is allowed for persons less than 18 years of age.


Over exposure shall be reported to the Saudi Aramco proponent, the Occupational Medicine Services Unit, and the Loss Prevention Department.

2.3 Responsibilities for Safe Handling

The Radiation Protection Committee (see GI 150.003) has full responsibility in all matters concerning the safe use, storage, and transportation of industrial sealed sources and x-ray machines used on Saudi Aramco property.

2.3.1 Contractor

The contractor appoints competent persons to be responsible for the immediate supervision and the enforcement of instructions and standards. Personnel involved in performing non-destructive testing must be certified and hold a valid "Permit to Use Material/Equipment Producing Ionizing Radiation".

2.3.2 Competent Person

Each radiographer will check at the beginning of each shift on the zeroing and recharging of dosimeters and on the condition of the equipment. A competent person familiar with all of Saudi Aramco radiation use requirements will make field audits to ensure compliance with Company instructions and standards. He must report the results of these audits to the applicable department responsible for the operation. Also he must be familiar with all equipment and procedures so that the proper corrective action can be taken in any emergency situation involving radioactive equipment.

2.3.3. Radiographer

At the start of each shift, radiographers must ensure that all equipment is in safe working order. All malfunctions must be reported to the supervisor or Competent Person immediately. The radiographer must also make sure that he is wearing a valid TLD or film badge and a direct-reading pocket dosimeter which has been charged and zeroed. One radiation monitoring instrument must be available for each source in use. Equipment must be transported to the work site with safety locks in place. Under no circumstance is equipment to be transported in an unassembled or open condition.

Upon arrival at the job site and prior to operating with any sealed source, the radiographer must ensure that non-radiation workers are not subject to radiation levels that would exceed that which is permitted. Radiation areas must contain radiation warning signs (see Figure IV.3) and be clearly displayed around the circumference of the radiation area. In addition, in populated work areas, a rope or tape barrier shall be erected around the radiation area. The area will be monitored with approved survey meter to ensure safe area for non-radiation workers is maintained. Further guidance on industrial radiography is provided in GI 150.003-4 and 00.AIP-08.

A weekly report on the condition of all equipment should be passed to the supervisor.


2.4 Shipping and Transportation

Government Permits are required for shipping radioactive materials into and out of Saudi Arabia. Additional information is available from Purchasing Services Division.

Transporting radiation sources to work locations requires a locked container located out of the passenger compartment. The vehicle shall have radiation signs on the front and rear.

2.5 Storage Areas

Upon completion of work or at the end of each work period, every sealed source must be returned to a storage area approved by the Saudi Aramco Radiation Protection Committee. Storage is usually within fenced area. All permanent or temporary storage areas (bunkers) must be approved of by the Saudi Aramco Radiation Protection Committee. Sources may not be stored in the back of a truck whether or not they are under lock and key. Radiation readings must be taken at the perimeter of the storage area and the radiation level must be within the acceptable limits given in GI 150.003. Radiation signs must be fixed to the barriers of all storage areas. (See Figure IV.3.)

• A log shall be maintained of radiation sources in storage, logged in or out, by source and responsible competent person in charge of source.

1.0 LIQUEFIED PETROLEUM GASES

Liquefied Petroleum Gases (LPG) are now being widely used in the construction industry. The precautions covered in this section are directed to those industrial operators who handle these gases, i.e., stores personnel and the actual operators using the gases. LPG is a term applied to combinations of hydrocarbons known under various trade names and also widely known as propane and butane.

ANSI A10.10-81

Safety Requirements for Temporary and Portable Space Heating Devices & Equipment Used in the Construction Industry

NFPA 58-89 Liquefied Petroleum Gases, Storage and Handling

1.1 General

These gases are colorless, heavier than air, and normally odorless, but for commercial usage, an odorizing agent is added for the obvious reason of facilitating detection in the event of accidental escape of the gas.

At normal temperatures, they are gaseous and can be changed into a liquid by the application of moderate pressure. In the liquid form, relatively large quantities of LPG can be safely transported and stored in suitably designed containers. The approximate ratios of gas volume to liquid volume are 275:1 for propane and 240:1 for butane.

Both gases are heavier than air at normal temperatures. Any leakage will form a gas cloud which will settle at the lowest possible level. It may ignite if a flame or sparks are present. This could happen at some considerable distance from the source of leakage. The gases form an explosive mixture with air, and they react vigorously with oxidizing materials. These gases can be highly dangerous; if the container is exposed to heat or flame, there is a high risk of

February 1993 - 1.0 Liquefied Petroleum Gases Page 332

explosion. To reduce the risk of explosion, the cylinders must be equipped with relief valves or fusible plugs.

1.2 Storage

1.2.1

Cylinders, whether empty or full, should be stored under cover for protection against the elements. The storage place should be detached from any other buildings and constructed of non-combustible material. It should preferably be a well-ventilated one-story building with all doors leading directly to the outside.

LPG cylinders must be stored at least 6.1 meters (20 feet) away from oxygen or oxidizers or must be separated from them by a fire wall rated at 30 minutes.

1.2.2

The building should be fenced-off and signs should be displayed both in Arabic and English: "No Smoking".

Water and dry chemical fire extinguishers shall be available.

1.2.3

Natural ventilation points should be positioned at both high and low levels.

1.2.4

All electrical fixtures should be of an explosion-proof type.

1.2.5

All gas valves, fittings, connections, and piping shall be made of stainless steel, brass or copper; rubber/plastic hoses are prohibited.

1.3 Handling of Cylinders

1.3.1

Cylinders must not be dropped or allowed to come into violent contact with each other.

1.3.2

They must be stored and used in an upright position, thus preventing the liquid from passing through the relief valve regulator and into the equipment.


1.3.3

They must not be placed in or near excavations or any low level area.

1.3.4

They must be placed on level ground and secured to prevent accidental tipping over.

1.3.5

Care should be taken that the valve assemblies are not damaged. The main valve should be closed and the valve cap in position when the cylinder is not in use.

1.3.6

Smoking is not permitted when handling cylinders.

1.4 Leakage

1.4.1

Cylinders, valves, connections, hoses, and pipings should be regularly inspected for damage or leakage. Detection can be carried out by the following methods, if flammable gas meter is unavailable:

1 Smelling 2 Touching: Leaking cylinder may be colder than those around it. 3 Listening: Sound of escaping gas. 4 Looking: Localized condensation or frosting.

1.4.2

Small leaks may be confirmed by using soapy water.

1.4.3

A leaking cylinder must be immediately removed to an open space, clear of all buildings and people or any potential source of ignition.

1.4.4

The cylinder must be placed with the leak uppermost.


1.4.5

The supplier must be notified immediately.

1.5 Transportation

1.5.1

Full or empty cylinders which are loaded on vehicles must be placed in an upright position, be adequately secured to prevent movement, and have valve caps in place.

1.5.2

The vehicle should have fire fighting and first aid equipment.

1.5.3

The vehicle must also display all the necessary warning notices.

1.6 Operation

1.6.1

In permanent or semi-permanent installations, the cylinder must be placed outside the building out of direct sunlight and the gas piped to appliances inside.

1.6.2

The cylinder must be secured in an upright position, away from excavation, pits, and other low lying areas.

1.6.3

The regulator and other equipment is to be connected and a test made to ensure that all joints are gas tight.

1.6.4

The regulator capacity must be suitable for the equipment being used.

1.6.5

Before lighting, a check is to be made to ensure that there is sufficient ventilation for the burner and that all combustible materials are removed from the work area.

1.6.6

Once the burner has been lit, it should burn with a steady blue flame with blue-green base cones.


1.6.7

A dry chemical fire extinguisher must be readily available at the work area.

1.6.8

Shut off valves shall be installed at the main tank supply and at the operating source. (See Loss Prevention Booklet, "Hazards of Gas Cylinders")

1.7 Action in Case of Fire

1.7.1

When cylinders are exposed to severe fire conditions and are engulfed in flames, no attempt should be made to extinguish the fire. In such condition, cylinders are likely to explode immediately.

1.7.2

The action to be taken in such an instance is to evacuate the area immediately and call the Fire Protection Department.

1.7.3

Cylinders which have been exposed to fire conditions must be adequately cooled with water before any attempt is made to remove them.

1.7.4

If cylinders are equipped with automatic relief valves and the fire exposure is severe, ignited jets of gas from these valves can extend as far as 6 meters (20 feet).

1.7.5

In the case of a small fire arising from gas leakage, it is possible to extinguish the fire by immediately turning off the cylinder valve. The cylinder should be approached from the opposite direction to the source of fire.

1.7.6

If a fire does not directly involve other cylinders in the vicinity, water hoses played on those cylinders will prevent increased internal pressure and minimize the risk of explosion.

1.7.7

All cylinders which have been involved in a fire must be returned immediately to the supplier, alerting the supplier that the cylinder was involved in a fire.


1.8 Bulk Installations

Before any bulk storage installation is undertaken, the LPG supplier should be consulted on the size of the tank required and the most suitable fittings for that particular installation, including relief capacity.

1.8.1

Temporary tanks are to be installed above ground on a dry, hard foundation away from drains, culverts, or hollows where it would be possible for any leaking gas to collect.

1.8.2

Tanks should not be exposed to heat or direct rays of the sun and they must be adequately protected against accidental or unauthorized interference.

1.8.3

Only trained personnel are to install bulk tanks and equipment. All items used must be of approved design and comply with the appropriate standards.

1.8.4

All pipeline systems must be tested to a safe working pressure after completion of the assembly.

1.8.5

Fire water protection shall be provided.

1.9 First Aid

If LPG has been inhaled, the affected person must be removed from the area, kept warm and rested, and not allowed to move about. If the affected person is not breathing, mouth-to-mouth resuscitation should be applied. No attempt should be made to give an unconscious person anything to drink. If the person is breathing, oxygen must be administered by a competent person. If liquid has gone to the eyes, they must be thoroughly washed out with water.

Medical aid must be obtained as soon as possible.

February 1993 - Construction Safety Manual: Plant Operations Page 337

2.0 PLANT OPERATIONS

The safe processing and movement of oil from underground to ship or transmission pipeline is the primary Saudi Aramco objective. Any construction operation which could affect the safety of oil processing and movement must be planned and performed in accordance with the operating procedures of the area in which the job is located.

Every plant area in Saudi Aramco operations has a specific set of operating instructions and the operating supervisor for that area has full responsibility for safety precautions. With this responsibility, he also has authority to issue work permits and stop any work if it is not in accordance with proper procedures.

It is therefore necessary for anyone expecting to work in an area where oil or gas is handled to know the rules and regulations and obey them.

Failure to follow the operating rules can result in not only destruction of Saudi Aramco property but also death of construction and operating personnel. This type of disaster must be prevented.

Saudi Aramco Safety, Health and Environmental Requirements - Plant Operations

2.1 Additional Information On Saudi Aramco Instructions and Standards

There are a number of additional instructions and standards which apply to construction operations, either inside or outside Restricted Areas. The contractor must determine which of these apply to him and ensure that his supervisory staff is familiar with them. This can be accomplished through discussions with operations management for the area and with the construction engineer. A meeting of all concerned prior to starting a job shall be conducted and a Hazard Identification Plan shall be prepared for review by Saudi Aramco Loss Prevention Department.

Because of the large number of instructions which might be applicable to a specific job, it is not practical to list all of them. The following, however, will be helpful in locating applicable instructions and standards.

February 1993 - 2.0 Plant Operations Page 338

2.1.1 General Instruction Manual

This manual is one which provides general instructions applicable to all Saudi Aramco areas and operations. The contractor will find most of the instructions applying to him in this manual.

2.1.2 Producing Instruction Manual

This manual is designed to provide producing operating personnel with instructions on operating practices and procedures for specific operations. The contractor would find it useful to know in advance what these procedures are and how they affect him.

2.1.3 Refinery Instruction Manual

This manual is designed for use in refinery operations. Its design and use is similar to the Producing Instruction Manual except that it applies to refinery operations.

2.1.4 Saudi Aramco Engineering Standards

These provide detailed instructions on how to do specific jobs and establish minimum standards to follow. The contractor must use all applicable engineering standards in the performance of his job. Failure to do so will result in immediate shutdown, a delay for which the contractor will be responsible. The Saudi Aramco construction engineer is familiar with the Engineering Standards and will assist the contractor. Saudi Aramco Loss Prevention personnel will advise and provide guidance on fire and safety problems.

2.2 Work Permit System

Any contractor planning to do work in a restricted area must obtain a work permit from the operations supervisor for the area.

To obtain this permit, the contractor must have personnel with a valid certificate to receive work permits. GI. 2.100, Work Permit System, provides the information needed to obtain such certificates and explains how to use them.

The work permit is a written permission to proceed with the work in accordance with the plans and the restrictions written on the form. Without a proper permit, work will not be allowed in the area. (See Work Permit System, Section II.1 of this Manual.)

2.3 Operation of Plant Equipment

It is expressly forbidden for any construction personnel to operate any valves, switches, push buttons, or other devices in an operating area. If the work dictates such action, the contractor personnel must call the operations supervisor to perform the service.

If the job involves work on equipment which is in service, a specific set of written procedures will have to be prepared and approved in advance by Operating and Safety personnel. The contractor must strictly follow these procedures. No deviations will be


permitted without the prior approval of the operation supervisor. Close contractor supervision will be required in these types of jobs.

2.4 Shutdown and Maintenance in Plant Operations

Shutting down a plant is the sole responsibility of operating personnel. Construction personnel should not, under any circumstances, be involved in any operational activity.

In certain emergency situations, it may be necessary for the contractor to shut down the job and even move his equipment to permit access for operating and maintenance personnel. This emergency activity must be done as requested.

2.5 Commissioning

GI 2.710, Mechanical Completion and Performance Acceptance of Plant/Unit, outlines the procedures and requirements for accepting new plants or additions to plants after they have been completed by the contractor. This is to assure that the plant is safe to operate in every respect. The contractor should familiarize himself with this instruction before he starts work.

If there is any question on the fire and safety aspects of this instruction, the contractor should contact the Saudi Aramco Loss Prevention Department for clarification and assistance.

2.6 Emergency Procedures: Saudi Aramco Disaster Plan

It is necessary for all contractors to familiarize themselves with the Disaster Control Plan for the plant and area in which the job is located. Each person working for the contractor must know exactly what to do when the emergency evacuation or stop work alarms are sounded and do it without delay.

The Disaster Control Plan does not normally require the assistance of any construction personnel. Saudi Aramco personnel are trained to handle the emergency.

If the emergency is the result of a construction operation, construction personnel will notify operating personnel immediately. The operating personnel will initiate alarm procedures and direct activities in controlling the emergency.

When the emergency alarm is sounded for any reason, all contractor personnel will immediately shut down their job, make it safe, and proceed in an orderly manner to the designated assembly point. They will be checked out by Security and should assemble at a point outside the area and await further instructions from the Saudi Aramco Disaster Commander.

Periodically, Saudi Aramco holds Disaster Drills to ensure the smooth functioning of its Disaster Plan. The contractor is required to participate in these drills just as if it were an actual emergency.


2.6.1 Gas Release Emergency Procedures

If there is a reason to suspect a gas release in the area through which you are driving:

1. Immediately shut off the vehicle engine and do not try to restart it. 2. Check the wind direction by looking at the windsock. 3. Get out of the vehicle and walk to a safe location generally in a crosswind

direction away from the point of release. 4. Inform plant operation employees of the situation. 5. Do not go and investigate, leave this to operations.

3.1 Preparation

3.1.1 SAES-A-004 (Pressure Testing)

The person in charge of hydrostatic testing should have read SAES-A-004 and GI 2.102, and fully understand the safety requirements and procedures involved with pressure testing. All persons who will work on the pressure test must be informed of the potential hazards and the necessary safety precautions. A work permit shall be issued prior to commencement of hydrostatic test operations.

3.1.2 Supports

Piping, vessels, supports and foundations designed for gas service shall not be overloaded by the extra weight of the test liquid. Temporary supports and braces may be required.


3.1.3 Vents and Drains

Vents of adequate capacity shall be installed at high points, to vent air / gas from the item while it is being filled with the test liquid. Hazardous gases or vapors must be vented clear of any area where personnel are working or where there is any possible source of ignition. Drains must be installed at a suitable location to allow removal of the test liquid.

3.1.4 Valves

Where isolation valves are used to contain test pressures, they must be of adequate rating for the pressure to be encountered. If isolation valves are used in lieu of blinds, provisions shall be made to ensure that no over-pressurizing can occur in equipment that is not being tested, due to possible valve leak.

3.1.5 Pipings And Joints

Prior to testing, investigations shall be carried out to verify whether or not temporary restraints are required to restrict the movement of pipings and joints during testing; when necessary, adequate restraints shall be provided.

3.1.6 Vacuums

On vessels or tanks which could collapse if subjected to a vacuum, there must be sufficient vent relief capacity to assure that the vessel cannot be subjected to a vacuum by draining the test fluid or by sudden cooling.

3.2 General Requirements

3.2.1

Do not approach system never previously tested, corroded piping or vessels, or vessels with welds never previously tested during the stepwise increase in pressure to the strength test pressure. After the strength test pressure has been reached and held for a specified interval, in accordance with SAES-A-004, the equipment may be approached. The actual pressure at which the system under test will be approached for close inspection shall be specified in the test procedure.

3.2.2

Pressure relief valve(s) shall be used to prevent over pressuring of the equipment.

3.2.3

Any ancillary equipment not under test must be isolated by valves (subject to part 3.1.4) or blind flanged and vented or disconnected.


3.2.4

Only calibrated test gauges shall be used and they should be mounted in the upright position. Pump discharge gauges must be visible to the pump operator for the duration of the test.

3.2.5

The equipment / vessel shall have adequate vacuum relief capacity to avoid damage or collapse, when draining the test liquid.

3.2.6

Lines should be drained and dried mechanically when the test liquid is corrosive or otherwise hazardous.

3.2.7

The pressure rise during a pressure test should be gradual and under control to allow time for material to strain, and time for personnel to check for leaks, see SAES-A-004 and GI 2.102.

3.2.8

A system under test shall be depressurized (with the exception of pressure due to a liquid head) before any work is done to stop leaks or repair weakness, including the tightening of bolts. In tightness tests, bolts may be tightened without depressurizing, if specifically approved in the written test procedure.

3.2.9

A block valve is required on the line from the test pump to the equipment under test.

3.2.11

Air shall not be used to displace test fluid from underwater equipment unless it has been determined that the equipment will not float.

3.3 Test Liquid

3.3.1

Water is a normally the preferred test liquid. Alternatives must be approved by a deviation from standard or they may be used if they are specifically permitted by SAES-4-004.

3.3.2

Salt water must not be used for testing any material subject to stress corrosion cracking in the presence of chloride ions (such as stainless steel type 304 or 18.8 - CrNi).


3.3.3

Pneumatic (gas) testing may be required as per SAES-A-004. Pneumatic testing other than as specified in SAES-A-004 may be done only with the explicit permission of the Consulting Services Department. Testing with air or other gases under pressure can be hazardous due to the explosion potential.

3.3.4

Possible changes in pressure due to thermal expansion, contraction or hydrostatic heads must be taken into account.

3.3.5

Written procedures approved prior to testing shall be followed for the disposal of test mediums containing chemical additives for control of corrosion or bacteria, as per the requirements of GI 432.000.

February 1993 - Construction Safety Manual: Chemicals Page 346

4.0 CHEMICALS

There are thousands of chemicals in existence and hundreds of new ones are being developed for commercial use every year. While almost all of these chemicals are beneficial in some way, they can be dangerous too. In fact, of the thousands of chemicals in existence, it is difficult to find any that are absolutely harmless.

When dealing with an unfamiliar chemical, it is always wise to assume that it is hazardous. The exposure to hazards associated with a material depends largely on its proper identification, handling, usage, transport, storage and disposal. In addition, materials which may be completely harmless in one application may be deadly in another.

There are too many chemicals and too many possible combinations to deal with them individually here. In the references listed, there are many sources of information on the identification, storage, transportation, use, and disposal of hundreds of chemicals. In the literature there are tables of hazardous chemical reactions. If the name of the chemical is known, the names of others with which it is likely to react dangerously can be found. The proper identification and labeling of chemicals is a very important safety precaution.

When dealing with a potentially harmful chemical, precautions should be taken to ensure that employees do not swallow it, inhale it, or allow it to contact their skin. The chemical must not be allowed to accidentally mix with other substances in transportation, storage, or use. It must not be subjected to undue shock, pressure, or heat. When the chemical is no longer needed, it must be safely disposed of or recycled.

4.1 Hazard Identification System

The hazardous nature of a material is related to the manner in which it is transported, stored or used; the materials with which it may come in contact; and how it is disposed of or recycled. There is no single identification system which can briefly indicate the hazards for all these conditions. Saudi Aramco uses NFPA 704 Identification of Fire Hazard Materials,


which indicates the fire hazards associated with any chemical and also describes the hazards which might be encountered in storage, transportation, use or disposal of the chemical.

Many of the materials in the Chemical Section, Class 26, of the Saudi Aramco Material System Catalog are marked by the use of hazard identification labels. The container may not be so marked, but it is indicated in the catalog description of the chemical. The system is based on four different symbols or numbers arranged in a diamond pattern (see Figure V.1).

The degree of possible injurious health effects, susceptibility of the materials to burning and to release of energy are rated by numbers (see Figures V.2 and V.2.A.). A zero (0) rating indicates little or no hazard and a four (4) indicates a high degree of hazard. It should be remembered that although a zero health hazard rating indicates that the material offers no hazards to fire fighters beyond that of ordinary combustible material subjected to fire, it does not mean that the material is harmless if inhaled or swallowed.

4.2 Health Hazards

Hazards to health arise from inhaling, swallowing, or skin contact. The severity of the hazard ranges from nuisance chemicals that produce no injury, to chemicals that on short exposure can cause severe injury or death. For industrial workers, the most prominent means of entry of a hazardous chemical into the human body is through the respiratory tract by inhalation. The next most important means of entry is through skin absorption. The least hazardous pathway is through swallowing the chemical, as this seldom occurs in industry. (Reference: Chemical Hazard Bulletins.)

4.2.1 Inhalation Pathway Hazard

Chemicals may be in the form of gases, vapors, dusts, or a mixture of these. The senses of sight or smell cannot be depended upon to warn of chemical hazards. Some gases are harmful in concentrations which cannot be detected by their odor. Furthermore, some gases paralyze the sense of smell. Hydrogen sulfide, at low concentrations, can very quickly paralyze the olfactory nerves so that harmful concentrations cannot be detected through smell. Ordinary automotive gasoline, to some extent, does the same thing.

When handling a volatile liquid, the maximum allowable concentration (MAC) of the vapor should be known and not exceeded. Where exhaust ventilation is not available, good mechanical ventilation must be provided or the work must be done outdoors.

In the case of a chemical spill, it may not be possible to control the maximum allowable concentration. Therefore it is necessary to keep the worker from breathing the vapor by limiting the amount of vapor through careful handling or through the use of local exhaust ventilation. If the concentration of the chemical in the air exceeds the threshold limit value (TLV) or MAC, then respiratory protective devices are needed. It is important that the right kind of device for the particular hazard be obtained. (See Breathing Apparatus, Section I.10 of this Manual.)

Dust is a common hazard. Whenever dusty material is handled, a respiratory hazard may exist. Exhaust ventilation, fans, blowers, and proper handling procedures must be used to keep the dust from entering the worker's breathing zone. If these methods fail, dust masks must be provided and their use enforced.


Fine droplets of liquid form whenever liquids are sprayed or splashed so suitable precautions must be taken to prevent the fine droplets of liquid from entering the worker's breathing zone. Ventilation is also recommended. If such methods are not adequate, suitable respiratory protection must be provided.

4.2.2 Skin Hazards

Skin contact/exposure hazard may not be as dangerous to life as respiratory hazards, but they are far more common. Dermatitis resulting from contact with harmful chemicals is a common work injury. Proper handling methods are the first step in protection. The second step, in the case of materials which act rapidly on the human body, such as corrosive chemicals (i.e. acids and caustics) is to provide a physical barrier in the form of goggles, face shields, hoods, gloves, aprons, suits, etc. The third step is to provide eyewash fountains and safety showers, which flush the material from the eyes or skin.

The type of personal protective equipment required depends on the hazardous characteristics of the chemical and the way it is used. Personal cleanliness is important. Thorough washing of the hands and face before meals, daily bathing, and a regular change of clothing will reduce harmful contact with chemicals.

4.2.3 Hazards of Swallowing Chemicals

In industry, swallowing chemicals does not occur frequently. The main precaution is to ensure that employees know that the material is hazardous if swallowed, and that they must wash their hands free of harmful chemicals before smoking, drinking or eating. Never store harmful chemicals in food containers or handle chemicals near food.

4.3 Emergency Treatment

4.3.1 Artificial Respiration

Persons overcome by harmful gases and vapors must be taken out into the fresh air and, if they have stopped breathing, given artificial respiration; if there is no heartbeat, commence cardiopulmonary resuscitation (CPR). Call emergency assistance immediately by telephoning 110.

4.3.2 First Aid

In case of accidental swallowing of chemicals, it is not wise to induce the patient to vomit. The hospital must be informed of the chemical injury or chemical swallowed and the person should be moved to the hospital immediately for medical treatment. In the case of caustics or corrosives, drinking a large amount of water, followed by medical treatment, is recommended. Telephone 877-8056, Saudi Aramco Emergency Medical Services, for poison information.

4.3.3 Showers and Eyewash Fountains

For skin hazards, the best treatment is thorough water washing under the emergency shower or eyewash fountain. Field treatment should only consist of


flushing away the chemical. The patient should then be taken to the hospital for treatment.

These water flushing devices are required, because working procedures and personal protective equipment may fail. In the case of materials that are immediately harmful to the eyes or skin, safety showers or eyewash fountains should be provided. They should be within 6 meters (20 feet) of the exposure site and accessible in an unobstructed straight line from the work location. Emergency showers shall be properly identified with signs and color background in accordance with SAES-B-55. A person who is blinded by a chemical must immediately be taken to the shower or eyewash fountain. Some emergency showers or eyewash fountains are designed so that standing under or near them activates the water supply. Others have hinged gates which are pushed to activate the shower, but all should be easily activated.

If the water piping to the shower or fountain is exposed to the sun, the water will become so hot during summer that it could scald the user. The piping must be buried, insulated or shaded from the sun or the line must be only a very short branch from a main water line that is used frequently enough to keep the water from overheating in the sun. Emergency showers and eyewash fountains should be checked daily.

CAUTION:

There are two important points that workers must be taught about the correct use of emergency fountains and shower:

1 Before removing goggles, face shields, or other personal protective equipment, the user must get under the shower or use the eyewash fountain to wash off as much of the chemical as possible.

2 It is a mistake to start for the hospital without first doing everything possible to flush out the harmful chemical. The eyes or skin must be washed for quite a long time to remove the chemical. It is necessary to wash the eyes holding the eyelids open with the fingers for at least fifteen minutes to free the eyes of bases or caustics. This will be painful, but it is absolutely necessary. In the case of acids, water will remove the acid quickly, but it is necessary to hold the eyelids open with the fingers, painful as this may be, and roll the eyes around under the shower or in the eye fountain to make sure that all acid is removed. At least fifteen minutes of thorough washing are required in the case of acid contact to skin or eyes.

Caustic alkalis such as sodium hydroxide and potassium hydroxide are much more difficult to wash from the skin or eyes. Strong alkalis of this type mixed with water feel slippery to the touch. The skin should be washed until the slippery feeling has gone and washing should be continued for at least 15 minutes.


4.4 Fire Hazards

4.4.1

Only the necessary amount of hazardous materials should be brought into the work place, usually not more than one day's supply. Hazardous materials must not be allowed to accumulate, and any extra amounts should be cleared from the work area. Slop liquids or trash should be cleared away immediately. All flammable materials should be stored according to the specifications of their Chemical Hazard Bulletins, (CHBs) or Material Safety Data Sheets (MSDS).

4.4.2

Smoking and the use of sparking devices near flammable liquids or finely divided combustible solids must be prohibited.

4.4.3

Blocking off air to a burning object is often possible in acid dip tanks or rubbish containers where a cover can be provided and dropped down on the container to smother the flames.

4.4.4

The use of fire fighting equipment, such as fire extinguishers or water streams, must be available in case all effective fire prevention measures fail to prevent a fire. (See Fire Prevention, Section I.11 of this Manual). Ordinary sand is a good extinguishing agent for smothering small fires. The fire hazards of most common materials can be found in the references given in this section. The proper fire extinguisher should be at the job site and readily available at all locations where a fire hazard is possible.

4.5 Reactivity Hazards

The manual of Hazardous Chemical Reactions, NFPA 491M, lists many of the chemicals which are likely to have dangerous reactions with other chemicals. As a general precaution, rough handling and shock should be avoided. Chemicals should not be allowed to mix with other chemicals unless it is known that no harmful reaction will occur.

4.6 Transportation, Storage and Disposal

4.6.1 Transportation

During transportation, hazardous materials must be protected against shock, accidental mixing with other materials, damage to containers, undue heat from the sun or other sources, and theft, which could allow the hazardous materials to come into contact with people who are unaware of the dangers. Specific recommendations for the particular material may be obtained from the Area Loss Prevention Office. The Saudi Aramco Chemical Engineering Response Team or Fire Protection Department also handles spills which occur during


transportation. A vehicle transporting hazardous chemicals must be suitably labeled.

4.6.2 Storage

The NFPA fire codes contain recommendations for safe storage of flammable liquids, compressed gases, and typical highly combustible or explosive solids. Precautions must be taken to avoid shock, undue heat, or unplanned mixing. There are some cases where separating walls or specified distances are required.

Specific storage recommendations for hazardous materials contained in the Saudi Aramco Chemical Hazard Bulletins (CHBs) and manufacturer-provided Material Safety Data Sheets (MSDS) should be followed. Incompatible chemicals should not be stored together.

A list of hazardous materials shall be kept by the contractor indicating type and quantity of materials used in each case, its hazardous classification rating and the quantity disposed of.

4.6.3 Containers

Hazardous materials must be stored in containers that are safe for the transportation and use of the material. Containers must be labeled with the appropriate hazardous materials label to indicate the actual contents. All safety factors must be observed when transferring material from one container to another and the receiving container must be labeled to correctly describe the contents. Empty containers previously used to hold hazardous material must be washed free of the material or destroyed.

4.6.4 Disposal (See GI 355.003 and 355.004)

Hazardous/toxic waste is liquid, solid and semi-solid material, which, because of the quantity involved, the concentration, and/or the biological, physical, chemical or infectious characteristics, pose a hazard to human health and/or the environment if it is improperly managed.

The following are some examples of waste materials which are considered hazardous/toxic, and are to be disposed of in accordance with established Saudi Aramco procedure.

• Waste paints and related products • Asbestos • Resins • Wood preservative products • Insecticides and pesticides • Flushing fluids / chemicals • Compressed gases (acetylene, oxygen, chlorine) • Flammable / combustible liquids (gasoline, diesel oil) • Corrosive liquids (acid) • Cleaning fluids • Explosives


• Flammable solids • Poisons and infectious chemicals • Radioactive materials • Magnetized materials • Polychlorinated Biphenyl (PCB (electrical transformer oil)

The disposal of hazardous material must be conducted by the contractor/user (c/u). The latter is obligated to perform the following:

Step 1:

The hazardous material must be identified by composition or content. If this is not possible, prior to arranging for disposal of the material the contractor/user should notify the AM&RD (Al Midra and Reclamation Division). The material will be provided to AM & RD in containers clearly marked "Hazardous Material" only, with no other conflicting or confusing words.

Step 2:

The c/u must follow manufacturers or literature safety guidelines (Material Safety Data Sheets, MSDS, Chemical Hazard Bulletins, CHBs, etc.) in addition to the Saudi Aramco procedures contained here. In cases where procedures overlap, the c/u should use the more conservative methods of disposal. Hazard rating codes assigned to SAMS material indicate the degree of hazard. (See Figure V.2A.) Obtain advice as needed from the Hazardous Materials Advisor, MHED (Materials Handling Engineering Division) at telephone number 872-7419 or from individual specialist units listed below:

Specialist Unit Telephone Number Central Area Storehouse Dept. (CASD) 872-7419

Laboratories Dept. (LP) 876-6725 Loss Prevention Dept. (LPD) 873-8779

Process And Control Systems Dept. (P&CSD) 875-3131 District Medical And Support Services (DM&SS) 877-8425

Industrial And Environmental Affairs Dept. (I&EAD)

874-1402

Fire Protection Dept. (FPD) 874-3345

Step 3:

The hazardous waste material must be adequately sealed up in containers to prevent leakage and labeled to denote composition or content.

Step 4:

Request a safety inspection of the material by the Hazardous Material Advisor.


Step 5:

When a large quantity of hazardous material needs to be disposed of, inform the:

a). Chemical Storage Segment, Material Disposal Unit, Reclamation Operations Section, AM&RD.

b). Hazardous Materials Advisor, MHED.

Step 6:

Follow the directives of the Hazardous Materials Advisor. (See GI 355.003.)

Step 7:

Transport the hazardous material to Dhahran Reclamation Yard using own truck or request suitable vehicle from the Transportation Department by following their established procedure.

Step 8:

Contact Assistant Superintendent, Reclamation Operations Section (ROS), AM & RD before a large volume of hazardous waste material is to be delivered. This person may request that the material be delivered directly to Delivery Point Code (DPC), 280 Reclamation Chemicals Storage And Handling Facility located near Abqaiq GOSP 3.

Note:

See GI 355.004 for any deviation from this established procedure for the handling, storage and disposal of Polychlorinated Biyphenyls (PCBs).

4.7 Work on Equipment Which Has Contained Tetraethyl Lead (Organic Lead Compounds)

4.7.1 Introduction

Tetraethyl lead (TEL) is an organic compound of metallic lead which is used to improve the octane rating of gasoline. This compound is highly poisonous. The hazard with tetraethyl lead is that, being a liquid it gives off vapors which can come into contact with the body by breathing or skin contact. Tetraethyl lead is very hazardous as its vapors can be inhaled, absorbed through the skin, or ingested through contaminated food or cigarettes. The best protection is to avoid any contact.

To make it easier to detect spills of tetraethyl lead, it has been dyed a bright orange color.


Tetraethyl lead, or sludges containing organic lead compounds, are likely to be found in the following places:

1. Wherever drums of the compound are transported, stored, or used. Leaking drums can contaminate ships' holds, trucks, and storage areas.

2. Wherever leaded gasoline is blended, handled, or stored.

3. In controlled disposal sites designated to receive organic-lead-containing materials. The sludge removed from leaded gasoline tanks is decontaminated by spreading and weathering prior to mixing with inert solids to reduce the total lead concentration to no more than 0.5% and transfer to a final burial site. Since tetraethyl lead is delivered dissolved in organic solvents, it also presents a fire hazard.

4.7.2 Precautions

Tanks that have once contained leaded gasoline (TEL) are considered dangerous thereafter even though they may have been used in other service for years. Such tanks should be permanently marked on the manholes with a sign warning that the tank has contained leaded gasoline and must not be entered without special precautions. Sludge pits where lead-bearing sludge from the leaded gasoline tanks has been buried must be marked with permanent warning signs.

Before entering any tank, an inquiry should be made as to the tank's previous service and a work permit obtained. Likewise, before marking excavations in or around refineries or gasoline storage depots, it is wise to determine whether leaded gasoline (TEL) sludge may be encountered. Work in cleaning, repairing, or dismantling tanks which have contained leaded gasoline requires special training and special precautions.

The workers must be medically certified and periodically examined before and during the course of the work. Using regular monitoring of TEL workers, any over-exposure to TEL should be reported to the Saudi Aramco proponent department, the Saudi Aramco Loss Prevention Department and the Industrial Hygiene Services.

The Saudi Aramco Industrial Hygiene Services and the Loss Prevention Department should be notified when work is to be done in TEL tanks or in areas with TEL contaminated equipment.

A cofferdam is an enclosure constructed to exclude water from a work area during construction. Cofferdam construction ranges from simple dikes to complicated timber or steel structures. Cofferdams must satisfy two basic requirements:

1. They must be strong enough to withstand the forces caused by water, soil conditions, and floating debris.

2. They should be as watertight as practicable, although some leakage, requiring pumping, must always be expected.

The most common type of cofferdam encountered in Saudi Aramco is constructed from steel sheet piling. The piles must be driven to design and penetration specifications and must encounter the pre-specified driving resistance. The steel piling is generally braced by a system of horizontal wales and struts which are designed to resist external forces.


Saudi Aramco Instructions and Standards:

Schedule 'D': Saudi Aramco Safety, Health and Environmental Requirements

Part 19 Excavations

Part 20 Work Over Water

1.1 Design

All cofferdams in excess of 1.2 meters (4 feet) in depth must be designed by a qualified engineer. Any deviations from the design encountered in the actual construction of the cofferdam must have the approval of a qualified engineer.


Any cofferdam which is to be constructed in a navigable waterway or which would constitute an obstruction or hazard to the operation of small boats or pleasure crafts must be approved in advance by the Manager, Saudi Aramco Marine Department. The latter will be responsible for coordinating its approval with the approval of required Government agencies.

1.3 Construction

All cofferdam construction work must be performed in strict compliance with the design drawings and specifications. All work must be accomplished by qualified craftsmen in accordance with accepted trade practices. Any unexpected soil or hydrographic conditions encountered during the construction must be reported immediately to the design engineer for evaluation and a possible mo dification of the structure.

February 1993 - 1.0 Cofferdams Page 361

1.3.1

If overtopping of the cofferdam by high waters is possible, means shall be provided for controlled flooding of the work area.

1.3.2

Emergency evacuation warning signals shall be provided and procedures developed. Notices shall be posted at the entrance to the job site, and throughout the area.

1.3.3

Walkways, ramps or bridges on cofferdams shall have at least two exit points. These shall be provided with standard guardrails.

1.4 Potential Hazards

The construction and the use of cofferdams have three primary hazards which merit special consideration.

1.4.1 Structural Collapse

Cofferdam structures may collapse as a result of the imposition of unexpected structural loads or the failure of the soil inside the cofferdam structures as evidenced by an upward heave or "blow-out" of the bottom. Such failures often occur with little or no warning, therefore a means of rapid exit from the enclosed cofferdam structures must be provided for all workmen engaged in work inside the structures.

1.4.2 Overhead Loads

Sump pumps, equipment, and machinery shall be mounted on a cantilevered platform outside of a cofferdam. This will eliminate overhead obstructions, which could present a hazard to the workmen engaged in construction within the confines of the cofferdam.

1.4.3 Dislodgment of Struts and Wales

All internal supporting structures must be secured against accidental dislodgment. The use of locking devices on wedges will prevent their accidental removal and the resulting collapse of the structure.

1.5 Inspection

1.5.1

General inspection should be carried out daily or after any weather condition or incident which might affect the safety of the cofferdam.

February 1993 - 1.0 Cofferdams Page 362

1.5.2

The security of all wedges should be carefully checked at the start of each shift.

1.5.3

Leaks can indicate a movement of the piles. Serious leaks should be reported at once to the engineer in charge of operations.

1.5.4

Pump intake fastenings and the pumping sump should be carefully checked at the start of each shift.

1.6 Leaks

1.6.1

Small leaks can be sealed by lead caulking in the clutches from the inside of the cofferdam. Minor leaks over a large area can be sealed by dropping light granular material into the water surrounding the cofferdam. The material will be sucked into the gap between the piles where it will form a seal.

1.6.2

Where large leaks are encountered which cannot be sealed as described above or there is an indication that the piling has moved, the cofferdam area shall be immediately evacuated of all personnel and the problem brought to the attention of the design engineer for correction.

February 1993 - 2.0 Marine Operations Page 364

2.2 General

All safety precautions that are applicable onshore apply and must be enforced while offshore, including the wearing of personal safety equipment. In addition, life vests must be worn while working on, over or near the water. Work over water may be either offshore or on a site connected to the shore. The hazards and the precautions for both situations are similar.

2.3 Behavior on Floating Craft

Personnel embarked on floating craft must obey the instructions of the person in charge of the vessel. In particular they must not obstruct his view or movements. They must travel in the passenger designated areas. They should not enter or climb on top of the pilot house and machinery space are similarly out of bounds. Personnel are expected to act in a responsible manner at all times.

2.3.1

Unexpected movements of the vessel even in good weather must be anticipated and guarded against. Personnel should keep away from the ship's side and make use of handrails at all times.

2.3.2

Life vests must be available for all personnel. Each person shall wear and know how to inflate a life vest (see Figure VI.1).

2.4 Preparation for Transportation by Sea

2.4.1

Loose and movable parts of material and equipment must be properly secured against movement. Such material and equipment must always be prepared as if for very rough weather. Sea conditions can change rapidly. Even with no wind, a swell can produce violent movement. Lashing must be adequate. Tank compartments being transported should be either empty or completely full. Tarpaulins or plastic coverings must be of adequate strength and well secured.

2.4.2

The Marine Department must be informed in advance so that they may prepare for the transportation of any hazardous cargo (acids, explosives gases, etc.) or cargoes with special characteristics (e.g., sensitive to water, delicate, or pilferage). Information on weights and measurements must be included for any shipment that requires a manifest (Saudi Aramco Form 9063).

2.4.3

Although the actual loading may be performed by another department, the Marine Department carries the ultimate responsibility for the safe loading and distribution of cargo on the floating craft under its jurisdiction.


2.5 Tide and Sea Effects

During pile driving and general offshore work, allowance must be made for wave action and the rise and fall of the tide, especially when erecting stages and platforms. Tidal predictions and weather forecasts are not completely accurate so a generous safety margin must be allowed.

2.6 Care of Tools and Equipment

2.6.1

Protective coatings reduce the corrosive effects of salt water and salt-laden air on tools and equipment. Nuts, bolts, and threads should be covered with grease or a similar protective coating.

2.6.2

Electrical and radio equipment must not be left exposed. When not in use, they should be protected by being returned to their boxes or being covered.

2.6.3

Objects that are dropped from any height can cause injury or damage, and they may be impossible to recover. For this reason, small hand tools should be secured by lanyards when working over or near water.

2.7 Housekeeping

Because of the confined space frequently encountered in Marine Operations, housekeeping is even more important offshore than onshore.

2.7.1

Tools must not be scattered around. Any spilled grease or oil must be cleaned up. Fire hose and rope must be coiled or flaked down clear of passageways. Doors and drawers should be kept closed.

2.7.2

Rags, papers, cigarette butts, and scrap must be properly disposed of. Proper disposal does not mean throwing the unwanted items overboard, thus polluting the environment. Trash cans and ashtrays should be used.

February 1993 - Construction Safety Manual: Diving Operations Page 367

3.0 DIVING OPERATIONS

Accidents involving divers and their equipment are generally serious, because diving operations are undertaken in an element unnatural to man. What would be considered to be a minor incident on land could cause crippling injury or even death in a diving operation.

Due to the extreme hazards of this occupation, divers must rely on their training, experience, and initiative to avoid accidents. For this reason, the strictest compliance with regulations, standards, and instructions must be observed at all times in order that everything possible is done to minimize the possibility of an accident.



GI 1197.001 Procedures and Safety Rules for Diving Operations (See Appendix G)

3.2.4.8

Gas cylinders taken under water shall be hydrostatically tested, inspected and stamped every two years.

3.3 Safeguards

When divers are preparing to enter or leave the water, or are in the water, or diving operations are underway, the International Code Flag "A" ("I have a diver down, keep well clear of area and maintain a low speed.") must be flown. (See Figures VI.2 and VI.3.)

Communications - A two-way voice communication system shall be used between:

1. Each surface-supplied air or mixed-gas diver and a dive team member at the dive location.

2. Two-way communication system shall be available at the dive location to obtain emergency assistance.

In addition, special lights and day marks for "vessels engaged in surveying or underwater operations" should be shown in accordance with Maritime Regulations (Figure VI.3).


3.3.1

Any person involved in an activity which could be a hazard to divers in the vicinity, such as those in charge of submarine blasting or masters of vessels about to move, start propulsion engines, or operate pumps, must be forewarned.

3.3.2

Adequate arrangements must be made to provide a safe means of access to and egress from the water. It must be kept in mind that a diver may be unconscious as a result of an accident.

3.3.3

Proper surface support and other facilities for the safe conduct of diving operations must be provided.

3.3.4

In all cases of emergency, the diving supervisor, the foreman diver, or the person in charge of a diver or divers must be the sole arbiter as to action to be taken. All personnel, whether connected with the diving operation or not, should take instructions from him.

3.3.5 Safe Operation of Divers

3.3.5.1

Bottom time and decompression time will be controlled by the diving supervisor or person in charge of diving.

3.3.5.2

On all work requiring four divers or more, a diving supervisor shall be present to facilitate coordination between divers and the surface.

3.3.5.3

All diving operations requiring more than two divers (using air for breathing) in water of a depth greater than 30 meters (100 feet), require the presence of a diving supervisor.

3.3.6

At all times when a diver is in the water, a stand-by diver must be on deck with a stand-by rig, fully dressed and ready to dive.

3.3.7

No diver working in water 9 meters (30 feet) or less shall be required to work longer than a twelve (12) hour shift without having a proper rest except for emergencies.


3.3.8

Repetitive diving should not be done as a routine. If the task necessitates the use of "repeats", efforts should be made to obtain additional divers. When this is impracticable, the tables must be strictly adhered to in order to avoid decompression sickness, which could require therapeutic treatment and could endanger the health of divers and delay operations.

3.3.9

Therapeutic decomp ression must take precedence over all other operational requirements.

3.3.9.1

Divers must remain in the vicinity of a recompression chamber for a period of twelve (12) hours after the last dive.

3.3.9.2

In the case of therapeutic decompression the period in 3.3.9.1 shall be extended to twenty-four (24) hours.

3.3.9.3

In mild cases of decompression sickness which have been treated under Tables 1, 1A, 2, 2A and 5 (US. Navy Diving Manual), a diver can be returned to work at the discretion of the diving supervisor.

After treatment for a case of "bends" under Tables 3, 4, 6 and 6A, a diver will not be permitted to dive again until he has been examined and passed as fit by a physician.

3.3.9.4

Each diver will maintain a personal logbook. Entries shall include but are not limited to the following:

• Diver's name. • Name and address of the employer of divers. • Date. • Name of the Diving Supervisor. • Name of the vessel, barge, or installation from which the diving

operation is carried out. • Maximum depth reached on each occasion. • Time he spent under water on each occasion. • Type of equipment used by the diver. • Work carried out by him on each occasion. • Details of decompression sickness or other illness/injury suffered

by the diver. • Any other factor relevant to health.


• Each daily entry will be signed by the diver and also by the diving supervisor.

• Divers must retain their logbooks for a period of not less than two years from the date of the last entry in the logbook.

3.3.10 Recompression Chamber

A recompression chamber must be on site during all diving operations in excess of 18.5 meters (60 feet). Whenever a recompression chamber is not available, only "no decompression" dives are permitted.

3.3.10.1

The maximum rate of ascent is 18.5 meters (60 feet) per minute in the case of air decompression and 7.6 meters (25 feet) per minute in the case of oxygen decompression.

3.3.10.2

Only necessary articles are allowed in the recompression chamber. No tobacco or any ignition source, including electrical shall be allowed in the chamber. Smoking shall never be permitted in the chamber whether under pressure or not.

3.3.10.3

The chamber shall be kept clean and dry.

3.3.10.4

Personnel in a chamber under pressure shall ensure that both they and all loose materials are kept clear of all atmosphere inlet and exhaust openings. The exhaust, which is under pressure, is especially dangerous because it subjects anything near it to a high suction pull capable of causing extreme bodily harm .

3.3.11 SCUBA Special Care

The use of SCUBA equipment in water over 18 meters (60 feet) in depth should be restricted.

3.3.11.1

SCUBA equipment shall not be used to depths greater than 45 meters (150 feet).

3.3.11.2

SCUBA equipment should never be used for dives requiring decompression.


3.3.11.3

In open water, SCUBA divers shall always be attached to a clearly visible float by a life line. In no case shall SCUBA divers be allowed to swim free.

3.3.11.4

In enclosed or restricted water such as beneath structures, either a lifeline or the "buddy" system must be used. There will be no untethered solo diving.

3.3.11.5

When using SCUBA equipment, divers will always wear an inflatable life jacket of the approved type.

3.3.11.6

No SCUBA diving should be carried out during darkness.

3.4 Physical Fitness

All divers must be physically fit for diving and have a certificate to this effect issued by a qualified medical practitioner: one who has experience and knowledge of the medical requirements for diving.

3.4.1

The medical certificate should state "Fit for Diving" and be not more than twelve months old.

3.4.2

Doctors carrying out medicals for divers should be aware of the importance of the condition of heart, lungs, chest, ears, nose, throat, and teeth. An EKG and chest X-ray are mandatory on an annual basis, while a long bone X-ray should be performed every three years.

3.4.3

For British divers, a current British Diving Fitness Register is acceptable and, likewise, any recognized fitness register for other nationalities.

3.4.4

All divers should be trained in First Aid/CPR, and on all diving operations, there should be an approved First Aid Kit suitable for use under hyperbaric conditions on site as recommended in the US. Navy Diving Manual.


3.5 Medical Diving Emergencies: Procedures and Responsibilities

Every incident/accident involving diving personnel shall be reported on Saudi Aramco Form 3208 with the responsible supervisor submitting a follow-up report on Saudi Aramco Form 681. Offshore emergency response procedures are given in Appendix B. Specific responsibilities are as follows:

3.5.1 Sports Divers

All divers must have an experienced person in charge with good knowledge of decompression sickness. He has to know the following two diving emergencies numbers to call if requiring help: 678-1248 from 6 a.m. until 6 p.m. 7 days per week; and 378-3691 from 6 p.m. until 6 a.m. 7 days per week. He should state his exact location and follow the instructions given to him by the coordinator answering the number.

3.5.2 Commercial Divers

The diving supervisor will immediately arrange recompression according to the appropriate table and report the incident to the coordinator manning the diving emergencies numbers.

3.5.3 Coordinator, Diving Emergencies

The coordinator, on call at either of the above numbers, will receive the information on diving medical emergencies. In the case of sports divers, he will direct them to the nearest available recompression chamber and alert its operator. He shall also inform the duty diving medical consultant who can be at the Saudi Aramco Preventive Medicine Services Division on 877-8916 (after work hours on 878-1697 or 878-0890).

In commercial diving incidents, the coordinator may elect to proceed with treatment using the appropriate table without notifying the diving medical team in cases of minor decompression sickness. In all type II bends and possible gas embolism cases, the duty diving medical consultant shall be notified immediately.

He shall send a monthly report of all incidents involving therapeutic decompression to the senior Occupational Medicine specialist.

3.5.4 Diving Medical Team

This will come under the jurisdiction of the director of Preventive Medicine Services and will be a multi-disciplinary group headed by the senior Occupational Medicine specialist. It will be comprised of a group of physicians with an interest and training in hyperbaric medicine who shall rotate as duty diving medical consultants. Nurses with special training will also be integrated in this group which shall constantly keep abreast with current practices. The diving medical team will provide this service to the Marine Department.


3.5.5 Marine Department

The Marine Department is responsible for the provision, maintenance, and manning of the recompression chambers.

3.6 Personnel Transfer at Sea

The following is to be used as guidelines for the transfer of persons at sea from vessel to vessel or from vessel to platform (or structure).

A. Personal Flotation Devices. These references are pertinent items from Loss Prevention Department GI 6.020 - Personal Flotation Devices for Work Over, On or Near Water.

3. Requirements.

3.1. Wearing of personal flotation devices are required as follows:

3.1.7

When working or riding on the deck of a marine vessel or craft during rough seas at the discretion of the person in charge of the vessel or craft.

3.1.11

When transferring to or from any water craft or to or from one water craft to another.

3.1.17

At any time when deemed necessary by the boat skipper, ship captain, supervisor, or the person in charge of the marine vessel, installation or craft.

4.1.3

Marine craft skippers, ship captains and aircraft pilots shall enforce the wearing of personal flotation devices in their vessels or aircraft. Failure of an employee to heed the instructions given by the person in charge of the marine craft or aircraft shall require the passenger to be removed from the craft with disciplinary action to follow by the employee's department.

4.1.4

Supervisors or persons in charge of personnel in facilities, installations, or work activities shall be responsible for having their personnel follow the requirements regarding the wearing of personal flotation devices.


4.2.

Contractors shall provide (fully functional, no defect) personal flotation devices for each of their personnel. They shall also provide their personnel with the necessary instructions or training on the proper way of wearing personal flotation devices. The proponent Saudi Aramco organization shall be responsible for ensuring that contractors comply with the applicable requirements of this GI 6.020.

B. Saudi Arab and contractor vessel crews shall also be issued with proper working uniforms and personal protective equipment such as shoes, gloves, glasses and hard hats.

A.2 CONTRACTOR SAFETY COMPETITION, RULES OF

COMPETITION

CONTRACTOR SAFETY COMPETITION JOB SAFETY EVALUATION

RULES OF COMPETITION

1. The competition shall be run over a six-month period (January to June and July to December) and shall be assessed according to the requirements of Schedule 'D' of the contract documents.

2. A contractor on a Budget Item (BI) who meets the following criteria shall be registered in the competition by the responsible Proponent (PMT).

a. Contractor and related sub-contractor exceed 50 for the entire six month period.

b. Estimated completion time exceeds the competition time period.

3. An unscheduled site inspection will be carried out by the Loss Prevention Department once before the 25th day of every even month. A contractor shall have a minimum of three ratings within the six month period. The Saudi Aramco Loss Prevention representative will report to the site office before he starts his inspection. Representatives of Project Management and the contractor shall be invited to accompany the Loss Prevention representative during the inspection. If it is inconvenient for a member of the Project Management Team or contractor's personnel to accompany the Loss Prevention representative during the inspection, the Loss Prevention representative will conduct the inspection alone - awarding appropriate scores. These scores shall be final. If during the inspection there is a difference of opinion over the points awarded, then the Loss Prevention representative will make the final decision.

4. The Saudi Aramco Project Management Team shall receive a copy of the inspection sheet, and they should distribute it to the appropriate contractor. Remedial steps shall be taken to rectify faults and improve the score rating. At the end of the competition, a copy of the six-month summary sheet will be provided to any contractor.

5. a. A contractor working on one BI at one location shall be evaluated, scored

and ranked separately. b. A contractor working on more than one BI shall have an entry in the

competition for each BI. c. A contractor working on the same BI at separate sites shall be evaluated by

site but the final score will be averaged. d. Multiple contractors working on the same BI shall be entered, evaluated,

scored and ranked separately. (This also applies to consortium partners - provided they meet requirements in 2 above.)

February 1993 - A.2 Contractor Safety Competition Rules Page 383

e. For those rare cases where there are multiple sites and multiple contractors on a BI, each site under the BI will be scored separately but averaged with all sites for that BI by contractor.

Exceptions to the above guidelines shall be reviewed by Project Management Team and Loss Prevention during initial registrations.

6. Following each inspection by the Loss Prevention representative, the original copy of the form SA-6710 shall be submitted to the superintendent, Central Area Loss Prevention Division, Building 3121, Room 113, Dhahran, not later than the 25th day of each even month. In cases of holidays or rescheduled days off, the first work day after the 25th is acceptable.

7. Any contractor who experiences a job related fatality, or serious incident that results in the hospitalization of five or more employees, and fire resulting in SR 10,000 worth of damage on any one of their sites within the competition period, will cease to be eligible for an award.

8. Should a registered contractor not retain an average of 50 or more employees for the entire competition period, they will be dropped from the competition.

9. Any item of concern not specifically covered on the Evaluation Form A-6710, shall be reflected in column #18 under Special Items.

10. Should any contractor find he has completed the project before the end of the competition period due to meritorious performance or reasons beyond his control, then he will still be eligible to compete in the final assessment.

11. Should it be found that the contractor has not entered into the required logs details which at a later date are determined to have occurred, e.g. restricted duty, lost work day cases, accidents, fires, etc., then he would be deemed to have broken the rules and forfeit the right to be included in the awards for the duration of that competition for which he was eligible.

12. Every hazard report Saudi Aramco Form 3744 issued and not corrected within 24 hours, a penalty of 500 points shall be deducted from the total score.

13. Should a contractor incur a second hazard report, disqualification for the rest of the competition period shall result.

14. Violations noted during an initial inspection which have not been corrected by the next general and/or follow-up inspection shall be deemed a repeat violation and a "0" score will be given for the entire section under consideration.

SCORING:

Where a section is inapplicable to a particular site, e.g. no scaffolding, cranes, etc., then that section will OK from the possible percentage score.


POINT ASSESSMENT:

Points will be assessed based on the gravity/severity of violations encountered and will range from 0 to 100. Points can be given from 0 to 100, depending on the judgment of the Loss Prevention Department representative.

OVERALL PERFORMANCE RATING:

Unsatisfactory= 0 - 65 Fair= 66 - 80 Good= 81 - 95

February 1993 - Construction Safety Manual: Hazard Identification Plan Page 394

A.4 HAZARD IDENTIFICATION PLAN (HIP)

INTRODUCTION

In reviewing the safety requirements for our design and construction activities (i.e. new, modified or rebuilt plants or facilities), it is difficult for even the most experienced engineer and/or contractor to identify all the potential safety hazards that may be encountered unless a systematic potential-hazard review is conducted as a part of a Hazard Identification Plan (HIP).

The attached Hazard Identification Plan (HIP) provides the method for conducting such a review. The hazards identified are classified as A, B or C according to their degree of potential human impact considering severity and probability (i.e. from most severe and probable to least severe and probable) during the initial design phase. This allows for a change in the methodology or operating procedure in the direction of reducing the risk associated with the hazard to an acceptable level, or eliminating it altogether.

February 1993 - A.4 Hazard Identification Plan Page 395

HAZARD IDENTIFICATION PLAN:

February 1993 - B.3 Emergency/Disaster Planning And Response Page 401

The potential for emergencies and disasters exists at all construction sites and facilities and their associated costs can be devastating in terms of employee casualties, business interruption, loss of capital investment, etc. These events cannot be avoided but the contractor can reduce their frequency of occurrence and severity of damage with effective preparation/planning. This can be accomplished by developing emergency response plans that address immediate concerns within the contractor's operations and which also interface, as required, with emergency response procedures developed by Saudi Aramco organizations.

The following guidelines (B 3.1 and B 3.3 and Figures) are extracted from the publication "Guidelines For Preparing Emergency Response Plans". These are generally used by Saudi Aramco operations as a framework for plan development. Contractors should refer to these guidelines for developing their own plans as appropriate, paying particular attention to the need for interfacing with local Saudi Aramco emergency planning procedures. Contractor's plans will need to be tailored to their specific operations and resources and the nature of their work with Saudi Aramco.

B.2.1 General Provisions

1. The purpose of the emergency plan is to provide guidance on the following:

• A facility/site emergency response organization's structure and responsibilities • Development of credible emergency/disaster scenarios and their consequences • Establishment of emergency control resources (human, equipment, etc.) and

procedures • Emergency response training and drills

2. Ensure that the emergency plan with the latest issue date is being used and it incorporates all amendments to date. It must have provision for any future amendments as addendum or reissues.

3. The emergency reporting instructions must be provided in the front of the plan. 4. The emergency telephone numbers must be provided in the front of the plan. 5. The disaster preparedness policy must be provided in the front of the plan.

B.2.2 Definitions

1. Emergency:

An emergency is an abnormal incident posing a threat to the safety of workers, residents, the environment or property at a facility or site and which can be brought under control using the resources and procedures for emergency response in place for the facility or site.

2. Disaster:

A disaster is an emergency which poses a more serious threat to the safety of workers, residents, the environment or property at a facility or site and which cannot be brought under control using the resources and procedures for emergency response in place for the facility or site. Whether an emergency becomes a disaster depends on the following:

• the type of facility; • the hazards of the facility operations;


• the proximity of neighboring communities or other facilities; • the capabilities of emergency personnel; and • mutual aid capabilities of outside agencies.

3. Emergency Planning:

This involves the development of a specific plan which details actions to be taken by trained personnel during an emergency in an effort to efficiently control it and minimize its net negative impact on workers, residents, the environment or property at a facility or site. This type of planning also extends to developing emergency control strategies and instituting training and drills for all facility personnel.

4. Disaster Command Center (DCC):

The location where the Emergency Manager and support staff assemble to respond to an emergency. It is a centralized location for monitoring the facility response and also serves as a command center for coordinating all communications, including the allocation and distribution of information. (This will also remain an onshore centralized location for an offshore emergency response episode.) During an offshore search and rescue (SAR) operation, this will become the SAR control center. A designated helicopter pilot will report to SAR control center to act as a search coordinator. Staffing from pertinent technical and support groups assures accessibility to all required resources for an overall effective emergency response.

5. Disaster Command Post (DCP):

A designated safe location near the emergency site from which the Incident Commander directs emergency control efforts. He directs operations and coordinates fire fighting, rescue and medical treatment activities during the emergency episode.

At some onshore facilities, the DCP is a specially equipped vehicle outfitted with facility maps, communication equipment and support information similar to a DCC. This equipment provides the means for contact with the DCC and for field coordination. At offshore facilities, the DCP would be a safe location designated by the Incident Commander which should be equipped with a telephone, radio communication and personal protective/identification equipment, at a minimum.

6. Table Top Exercise:

This is a disaster management simulation where key personnel face a hypothetical disaster situation developed by a skilled moderator. Weaknesses are identified by evaluating the results of the exercise and corrected by revising the plan.


7. Planning Committee:

A planning committee is a body comprising of members from key functional groups within the organization. This is set up to develop an emergency plan using the broad expertise of its members.

8. Planning Coordinator:

An individual who is qualified to develop an emergency plan to direct its development through a planning committee. This individual is required to process great depth of knowledge of emergency response and disaster control practices and procedures, and manpower organizational capabilities for his facility or site. He can review and use Saudi Aramco approved emergency plans from other similar facilities or sites in the development or modification of his facility/site plan.

9. Emergency/Disaster Response Organization:

The Emergency/Disaster Response Organization is a structured working group whose function is to control an emergency or disaster. The structure of this group is typified in Figure B.1. The organization is basically compris ed of the following positions with their delegated responsibilities.

A. Key Positions

This function is usually performed by an operations employee who reports to the DCC to manage radio transmissions, telephone lines, operate special equipment such as DVD, EARS, etc., and record all message traffic.

(l) Environmental

This function is usually performed by an assigned environmental specialist whose responsibilities include providing environmental monitoring services and spill containment/recovery advice to the Emergency Manager and Incident Commander.

B.2.3 Plan Development Action Items

Task 1: Assign (or Establish) Planning Coordinator (or Team)

1. A planning coordinator must be assigned; or

2. A planning committee/coordinator team must be established.

Task 2: Establish Scope and Objectives

3. A scope and written objectives must be developed for the site.


Task 3: Identify Emergency/Disaster Scenarios

4. Develop emergency/disaster scenarios specific to the facility or site as follows. (Use Figure B.2 for scenario development):

• Planning Coordinator/team to identify emergency/disaster situations. • Group these situations into generic scenarios (e.g. tank fires, pump

fires, liquid releases, vapor releases, explosions, natural disasters, etc.)

• For each generic scenario, select the credible worst case emergency/disaster situation to represent that scenario (e.g. the largest tank fire) and fill out Part A (Description) and Part B (Possible Causes) of the Scenario Analysis Sheet (Figure B.2). Similarly, describe all scenarios on separate sheets and assign a rank order to each in Part E (Evaluation) based on likelihood of occurrence. (The "consequences" of Part E will be developed as part of Task 4, "Assess the Consequences of Scenarios".)

The following information is useful in identifying emergency/disaster situations (initiated on-site or off-site) within each generic scenario:

• Fire

Fires are generally caused as a result of ignition of a gas (or liquid) hydrocarbon leak under pressure. Unburned liquid hydrocarbon pools in the ground and fuel the fire to increase its intensity and spread. All situations within this scenario can lead to disasters if fire spreads beyond the capabilities of the fire fighting systems/personnel in place. Generally, this occurs if the response is not quick to contain the fire to a manageable limit before it approaches a disaster level. Some examples of potential emergency/disaster situations for the fire scenario are:

• congested multiple process unit area fire • flammable liquid tank storage area fire • wharf loading and unloading area fire

• Explosion

Flammable vapor releases are one of the most significant sources of explosions and the potential for casualties and property damage is high. Some examples of potential emergency/disaster situations for the explosion scenario are:

• boiling liquid expanding vapor explosion (BLEVE) of storage, sphere, bullet or process vessel

• runaway (exothermic) process chemical reaction • gas explosion from a large volume release of refrigerated LPG • unconfined vapor cloud explosion (UVCE) from a flammable vapor

release


• Flammable Vapor Release (FVR)

In the petroleum industry, the possibility of release of flammable vapor poses a great risk. Some examples of potential emergency/disaster situations for the FVR scenario are:

• failure of piping connection to pressurized storage sphere (or bullet), or refrigerated tank

• tank overfill • LPG tanker accident resulting in containment failure • high pressure gas pipeline rupture

• Toxic Vapor Release (TVR)

Toxic materials may or may not be flammable but could be in a high enough concentration to pose a health risk when released as a vapor. Some examples of potential emergency/disaster situations for the TVR scenario are:

• rupture of pipeline or well blowout releasing H2S vapor • rupture of storage container releasing chlorine/ammonia vapor • rupture or leak of amine regenerator overhead accumulator

piping/flange to release H2S vapor • failure of H2S compressor seal releasing the vapor

• Hazardous Materials Spill

Hazardous materials are used as solvents, reagents, and catalysts in various processes. A likely situation for a hazardous material spill is from the tanker vehicle transporting it to the facility or during its transfer from the tanker vehicle to its process usage or storage point. Other examples of potential emergency/disaster situations for the Hazardous Materials Release/spill scenario are:

• TEL/TML gasoline antiknock compound liquid release • rupture of storage container or associated piping releasing

chlorine/ammonia liquid • rupture of storage container or associated piping releasing sulfuric

acid liquid

• Natural Disaster

Each facility or site is susceptible to natural disasters (e.g. high winds, flooding, etc.). The impact of natural disasters to cause other related process disasters should be recognized in the planning stage. Historical data on disasters at similar facilities or sites coupled with weather data can help in predicting the frequency of natural disasters for the area. Another source of such information is the Saudi Aramco Risk Analysis Manual.

Task 4: Assess the Consequences

5. Complete each scenario analysis sheet started in Task 3 by describing the incident size, duration and effect on operations.


6. Enter an estimate of the magnitude of potential consequences in Part E (Evacuation) of the Scenario Analysis Sheet (Figure B.2) after considering the following factors for each scenario:

• Size (including explosive potential, maximum fire areas, maximum spill volume and area, maximum vapor cloud volume).

• Growth spread of impact area resulting from the spread of a fire, toxic vapor cloud, or other undesirable product of the emergency/disaster episode.

• Amount of advance warning. • Impact (including severity of potential damage, potential casualties,

effect on surrounding population, domino effect of sequential explosions, and total duration).

• Controllability of incident based on level of emergency/disaster training of personnel and adequacy of equipment available within a facility or site.

• Reaction (or response) time and effectiveness of facility resources to control incident.

After the Scenario Analysis sheets have been completed for each scenario, assign a rank order in Part E based on consequences. The plan coordinator selects the scenario which represents the most likely event with the severest consequence(s) as the basis for developing the emergency response plan. This choice should be approved by Contractor management.

Task 5: Review Emergency Control Needs

7. Use the Disaster Control Tasks Checklist to determine all tasks required (see Figure B.3).

8. Assign a team member to develop the facility's response.

9. Develop and document the assigned response.

Task 6: Available/Needed Resources

10. The methods to identify, estimate, and establish available needed resources are as follows:

(a) Develop an inventory list of critical supplies and equipment needed to control the emergency disaster scenarios in Tasks 3 and 4.

(b) Ensure that these critical items are stored together at one easily accessible location (or the critical items store itself if accessible).

(c) Display the list of critical items on the entrance to the critical items store.

11. Identify and list the entities responsible for supplying food, water, shelter, transportation, emergency equipment, additional manpower, external mutual aid, medical support and cost accounting.


12. Determine that the resource needs in item number 10. (above) have been met List contingencies to cover failure of any of those entities indicated in item 11. to supply the needed items.

13. Survey alternate outside sources to determine their ability to supply resources which may be in short supply.

14. If a mutual aid agreement has been established, develop an inventory of equipment and supplies that any mutual aid entity is expected to bring with them when they respond.

15. Establish a telephone and personnel list of 24-hour contacts at all mutual aid entities.

16. Determine and document that the equipment and supplies provided through mutual aid are compatible with emergency/fire protection equipment at the site.

17. Measure the response/travel time needed by all mutual aid entities to respond to an emergency/disaster at the site. Establish the needed time range for all outside resources to reach the site.

18. List and detail all high cost items and their corresponding authorization levels.

19. List emergency response skills required to control all scenarios selected in Tasks 3 and 4.

20. Compare required skills with available skills of construction/site personnel.

21. Establish a Disaster Command Center (DCC).

22. Consider the need to provide an alternate location for the DCC in case the original location is rendered unusable.

23. Supply the DCC (and alternate) with:

• telephone, fax, and other radio communication/alarm equipment • emergency power and lighting • reference materials (e.g. emergency response manuals, call out lists,

Material Safety Data Sheets (MSDSs), drawings, photographs, maps, etc.) and emergency equipment (e.g. flashlights, spare batteries, camera, battery powered megaphones, etc.

• office equipment (e.g. dictating machines, tapes, flip charts, stationery items, etc.)

24. Establish a Disaster Command Post (DCP) vehicle/safe location near the emergency site.


25. Ensure that the DCP is set up with supplies similar to the DCC (except on offshore facilities where the DCP may only have a telephone, radio communication and personal protective/identification equipment).

26. Additionally, ensure that the DCP also has the following:

• self-contained breathing air • megaphone • binoculars • safety/environmental monitoring equipment • means of identification (vest, hat)

Task 7: Emergency Response Organization

27. Establish an emergency/disaster response organization.

28. Ensure there are sufficient personnel to fill all assigned positions and alternates/substitutes identified and on standby to fill critical positions should it become necessary.

29. Ensure that each assigned position has a documented detailed description of its responsibilities. Such a description must include:

• duties of the position • reporting relationship • reporting location

30. Verify and document that all assigned individuals are aware of their responsibilities.

31. Develop a physical method to identify each individual in the organization chart by position (ID. badges, vests).

Task 8: Develop Emergency Response Procedures

32. Ensure that the planned facility/site emergency response procedures are structured according to the logical progression of action items given in Figure B.4.

(a) Reporting Emergencies:

(1.) Report to senior operations person in control room using radios, telephones, manual pull box alarms, or public address systems. (Emergency telephone numbers or local 110 instructions should be posted near or on all telephones.)

(2.) Determine how significant does an incident have to be to be reportable.

(3.) Suggested wording for reporting emergencies (or drills) is shown in Figure B.5 (Emergency Reporting Instructions).


Also see section VII.A (Reporting Emergencies) of the plan (see Task 9: Write the Plan).

(4.) Details of the telephone and radio systems (i.e. different dialing and radio frequencies) should be in the appendix of the plan.

(b.) Initiate The Alarm:

All emergency related signals (i.e. "stop-work", "evacuation", and "all clear") and expected actions relating to each signal alarm must be established and followed.

Authority and criteria for sounding the different alarms must be clearly stated in the plan.

(c.) Assess The Situation:

The Incident Commander must follow-up on every emergency declared by reporting to the incident site to assess:

• the emergency response actions taken or being taken • additional actions and resources required to control the situation • extent of damage to property and harm or negative impact to life. • existing hazardous conditions and their likelihood to escalate.

(d.) Mobilization Of Resources:

1. Actions are taken by facility/site personnel to mobilize the facility's internal resources (human, equipment, etc.) and, if needed, contact external groups to mobilize their resources to the scene as developed in Task 6 (Available/Needed Resources).

2. Plant personnel assigned to the emergency response organization are to proceed to their preassigned locations and await instructions from the Emergency Manager or Incident Commander, as applicable.

3. Non-essential plant personnel are to be evacuated to preassigned assembly areas at a safe distance from the incident scene. Supervisory or assigned personnel are to take head count and DCC is to organize search and rescue for any missing personnel.

4. Support groups such as Security, Medical and Fire Protection are to report to their preassigned locations and must commence any preauthorized emergency response related actions.


5. At least two methods of in-plant communication should be available (e.g. radio and telephone). One in-plant radio channel is reserved as the main communication link between the Emergency Manager and Incident Commander. At least two methods of communication are necessary for external contacts (e.g. telephone, radio, Direct Voice Dispatch - DVD, Emergency Alert and Response System - EARS, etc.).

A telephone number with a pre-recorded message providing essential up-to-date information on the incident (e.g. 113 in Dhahran) will be established.

(e) Suppression/Control Of Incident:

A separate control procedure must be written for each generic incident scenario developed in Task 3 (Identify Emergency Scenarios). This procedure is based on facility operating instructions detailing the rapid and safe sequential shut down of process units/equipment involved or affected by the particular incident scenarios.

(f) Post Incident Actions:

There are follow-up actions needed once an emergency is declared under control by the Emergency Manager. These actions are:

1. Stand Down And Fire Watch

The Emergency Manager gives the "stand down" order to emergency response personnel. At this time, some personnel are released from duty, some are assigned to gather evidence, on the emergency episode and others are to maintain a fire watch if there is danger of reignition. The fire watch is set up by Fire Protection following consultation with the Emergency Manager.

2. Investigate And Report

Incident investigation of causes and reporting can be made according to prescribed procedures. GI. 6.001 (Notification Requirements For Incidents) and GI 6.003 (Guide For Committees Investigating Major Incidents) are two sources which provide guidance for developing such procedures.

3. Restore Operations

This covers all post-emergency control actions which must be followed to restore normal operations at the facility. This includes, but is not limited to:

• demands of caring for injured and homeless


• repairing damaged equipment to bring process equipment

on-line • collecting evidence for the reporting requirement • determining secondary hazards that may have developed

4. Revise The Plan

All new information gained as a result of the incident should be analyzed to determine what improvements could be made to the facility's Emergency Response Plan. These improvements should be integrated into the Plan and all emergency response personnel should be retrained and drilled to ensure that they are familiar with and proficient in following upgraded procedures.

33. Develop procedures for the following emergencies/disasters (onshore/offshore as applicable):

• emergency unit shutdown • individual equipment isolation • process unit fire • tank farm fire • marine dock fire • off-site pipeline leak • personnel rescue • medical emergencies • toxic/flammable/corrosive gas leak • evacuation from units and buildings • process upsets • breaches of security (including terrorism or sabotage) • For more information refer to the Saudi Aramco Loss Prevention

Department "Guidelines for Preparing Emergency Response Plans" manual.

34. Complete the emergency reporting form given in Figure B.5 and follow the instructions contained therein to report such event(s).

Task 9 - Write the Plan

35. Ensure that the plan has a Corporate Policy Statement on emergency/disaster preparedness, and is prepared in conformance with the format and instructions presented in the Saudi Aramco Loss Prevention Department "Guidelines for Preparing Emergency Response Plans" manual.

A typical Emergency Response Plan will follow the outline given in Figure B.6.

36. The plan manual must be reviewed and signed off by all outside mutual aid entities expected to respond to an emergency at this site.


Task 10 - Emergency Response Training and Drills

37. Develop, document and follow the emergency response training/drill items given below to ensure that all personnel expected to participate in emergency response are proficient in its theory and practice.

• table top exercise • classroom training of personnel • simulation of DCC operations during an emergency • field simulations/drills of credible scenarios

38. Ensure that alternates (or standby) personnel are also trained and drilled on emergency response

39. Train and familiarize all personnel with the provisions of your emergency response manual.

40. (a) develop a document and drill schedule in your manual

(b) ensure that these include full scale disaster simulations

41. Hold and document critique sessions following all drills, simulations and/or actual incidents.

42. Establish a procedure to ensure that all suggestions from the critique sessions are incorporated into your manual.

Task 11 - Review and Revise the Plan

43. Provide for regular reviews (e.g. documented tickler date) and update the plan at least once a year through the plan coordinator.

44. Keep a record of all amendments and maintain it in the front of the plan document manual.

45. Keep a current list of all document manual holders and periodically forward them copies of any amendments.

C.1 FIRE SAFETY CHECKLIST FOR EVALUATING

CONSTRUCTION MATERIALS STORE YARD

(Based on NFPA 231-APPENDIX C) PROTECTION OF OUTDOOR STORAGE

I. SELECTION OF A SITE

A. Adequate fire department protection.

1. Travel time to site, primary factor.

B. All-weather roads adequate to carry fire department apparatus.

1. Kept clear at all times.

C. Available water supply of sufficient pressure and quantity.

D. Sufficient clear space from combustible structures or other storage which could be an exposure hazard.

E. No danger of flooding.

1. Run-off from fire fighting water should be considered.

2. Drainage from fuel spills should travel away from all storage.

F. Enough clearance from storage site to highways or major roads.

II. FENCING SITE

A. Entire site should be fenced to control access.

B. Two 15' gates, directly opposite each other (180o) are required to permit ready access of fire apparatus to any part of the storage area regardless of wind direction and location of fire.

III. PILING OF MATERIALS

A. LOW HEIGHT and SMALL AREA are the ideal conditions.

1. Reasons for this are -

(a) stability of the pile under normal and fire conditions (containers maximum: 2 high).

(b) access to the seat of the fire with hose streams from the ground.

B. AISLES must be maintained between individual piles; between piles and buildings, and between piles and the boundary line fence for the storage site, to allow access to all sides of the piles.

February 1993 - C1 Fire Safety Checklist Page 429

1. Aisles minimum of 10 feet wide.

C. DRIVEWAYS of minimum 15 feet width are required to permit travel of fire apparatus to all parts of the storage area.

1. Driveway and aisle widths should be increased to at least equal the height of piles of goods, since they also act as firebreaks to limit the spread of fire.

D. ARRANGEMENT OF MATERIALS is important to reduce the speed of the spread of fire.

1. Generally less hazardous materials should be stored upwind and more hazardous materials downwind.

2. Piles or "blocks" of small piles are arranged with combustibles and non-combustibles in alternate locations -

(a) This technique tends to isolate a fire, allowing greater chance to contain it within the pile or "block" of origin.

(b) This checker board pattern of materials also helps reduce reliance on wind direction to control the spread of a fire.

IV. BUILDINGS

A. Buildings within storage yards should be at least 50 feet from the nearest storage pile.

1. This space should remain clear and free of combustible materials, at all times.

B. ARRANGEMENT OF BUILDINGS should also consider the effects of wind on the spread of fire.

1. One approach is to have less hazardous shops and sheltered activities upwind, more hazardous ones downwind.

2. In addition to the above, leave plenty of clear fire- break space between buildings (50 feet minimum), and alternate hazardous shops or stored goods with those structures housing less hazardous goods or activities. Again, this will help counteract unfavorable winds.

V. FIRE PROTECTION

A. Communications -- a reliable means of communication with the Saudi Aramco Fire Protection Department shall be provided. Normally this will be a Saudi Aramco system telephone.

WARNING: Prompt NOTIFICATION of the Fire Protection Department is mandatory and absolutely necessary to prevent out-of-control fires.


B. Portable fire extinguishers shall be provided throughout the storage area and the buildings located as to be quickly available for use at any point.

C. Standard Live Hose Reels shall be provided throughout the storage areas to allow fast application of firewater onto any location within the store yard. These hoses are easily handled by one man and can deliver significant quantities of water. Full coverage of the interiors of all buildings must also be provided.

WARNING:

1. The need to notify the Fire Protection Department and man these live hose reels as fast as possible cannot be over-emphasized.

(a) Fire areas increase as an increasing multiple of time, not at a constant rate. The longer you wait to apply water on a small fire, the more you will be surprised at the size the fire has attained.

(b) These 1-1/4" diameter hoses allow one person to apply about 100 gallons/minute without difficulty.

2. Two inch steel (galvanized) lines shall be used to feed these hoses. Each hose reel will have a valve at the tie-in to the 6" loop.

D. Standard Fire Hydrants - Saudi Aramco Engineering Standard B-7C requires type 509-G hydrants for protection of outdoor storage. Depending on system pressure, the 2-1/2" hoses used by the Fire Protection Department can require 4 to 5 trained men to handle. It is for this reason that fire hydrants are not normally provided with hose or used by construction yard personnel.

1. In areas where there is no Fire Protection Department within reasonable distance, sufficient 2-1/2" hose, and other equipment such as nozzles, hydrant wrenches, etc. shall be kept on the site, suitably located, housed, and maintained ready for use.

2. Hydrants and all fire fighting equipment shall be accessible for use at all times. No temporary storage will be allowed to obstruct access for fire fighting.

E. Details of Water Supply

Connect to main with gate valve.

Provide a looped system valved to feed hydrants from either direction.

(Block valve(s) to isolate either 50% of the piping and hydrants.)

Materials - carbon steel pipe, okay for temporary yards.

(Good mechanical strength, repairable.)

Size of loop piping, 6" diameter minimum.


VI. GUARD SERVICE

A. Guards trained in the use of live fire hose reels, fire extinguishers and the fire warning system shall be on site at all times when the yard is otherwise unoccupied.

1. Supervised rounds are suggested to verify the entire property is periodically observed.

2. Means of communication necessary to summon assistance during emergency situations shall be provided.

VII. YARD MAINTENANCE AND OPERATIONS

A. The site shall be kept free from accumulation of unnecessary combustible materials such as empty cartons or other packing or packaging materials.

B. All electrical equipment and installations to comply with National Electrical Code.

C. Employees' smoking areas shall be clearly designated and no smoking strictly enforced outside these "safe" areas.

D. Motor vehicles shall be garaged and repaired outside the yard area, in a non-combustible structure or unsheltered. Fuel handling shall comply with NFPA 30, Flammable and Combustible Liquids Code, at a safe distance from the storage yard.

A site layout plan of the materials storage yards shall be submitted to the Loss Prevention Department Area Fire Prevention Engineer for review. All essential features of this "Checklist" shall be clearly illustrated on a site drawing of the proposed yard. Two copies of this drawing (done accurately to scale) will be submitted and once approved, one signed copy shall be kept at the site for periodic review. Changes to the original storage yard layout must be reviewed and concurred by Loss Prevention Department.
