Page 3: Day 1

Introduction• Throughout the day, many tasks will be

repeated with little conscious thought. – This can make work dull and increases the chance

of an accident.• Safety consciousness is a vital part of your

work.• Safety training is conducted to make you aware

that dangers exist all around you every day.• Jobsites are always changing and new hazards

are continuously emerging.

Page 4: Day 1

Video:Construction Accidents

Page 5: Day 1

Importance of Safety

• Safety is a learned behavior and attitude, as well as a way of working.

• A safety culture is created when the whole company sees the value of a safe work environment.

Page 6: Day 1

Importance of Safety

• Companies with a strong safety culture have lower accident rates and a lower turnover of personnel.

• Other benefits…– fewer at-risk behaviors– lower absenteeism– higher productivity– can lower a company’s Experience Modification

Rate (EMR)

Page 7: Day 1

Importance of Safety

• Factors...– perceiving safety as a core value.– strong leadership.– the involvement of all employees.– using the workplace as learning environment.– continually monitoring performance.– effective communication of safety goals.

Page 8: Day 1

Accidents

• An accident is defined as an unplanned event that may or may not result in personal injury or property damage.

• Accidents can happen to anyone at any time, in any place.

Page 9: Day 1

Accidents

• 5 Types of Accidents:– Near-miss: no one injured and no property damage– Property damage: results in damage to tools, material or

equipment.– Minor injuries: minor cuts, bruises, or strains but worker

returned to full duty the next day.– Serious injury: results in temporary or permanent

disability.– Fatalities: death

Page 10: Day 1

Accident Costs• When an accident occurs, there are direct costs such as

the medical costs of the injured worker, and indirect costs such as lost productivity and the cost of training a replacement worker.– Direct Cost: Can be foreseen

• Medical Bills• Worker’s Compensation• Liability Insurance Premiums

– Indirect, Hidden cost: Are not foreseen• Property damage• Equipment damage• Production delays• Supervisory time• Retraining• Image/Morale

Page 11: Day 1

Indirect Cost• Indirect or hidden costs can exceed direct costs by

two to seven times.

Page 12: Day 1

Activity:5 Types of Accidents

Objective: List the 5 types of accidents and give examples of each.

Group Task: Prepare a Tree Map to classify each type of accident and give examples of each. Be prepared to present work to the class (p 1.2).

Agenda:1. QOD & Measurements2. Basic Safety PP3. Video – Failure to Communicate4. Activity – 9 Causes of Accidents5. Review

Standards:AC-IFOS-2. Understand and practice construction safety.

Page 16: Day 1

What Causes Accidents?

• 9 Causes of Accidents– failure to communicate– rationalizing risk– unsafe conditions– poor work habits– alcohol and drug abuse– lack of skill– intentional acts– unsafe acts– management system failure

Page 17: Day 1

What Causes Accidents?

• Poor Work Habits such as goofing off, carelessness, and horseplay can result in serious accidents.

Page 18: Day 1

What Causes Accidents?

• Rationalizing Risk is the act of ignoring safety warnings and practices because you make an excuse for doing so.

• Examples…– Crossing boundaries because no activity is in sight.– Not wearing safety goggles because it will only take a

minute to make a cut.– Removing your hard hat because you are hot and you can

not see anyone working overhead.– Not tying off your fall protection because you only have

to lean over about a foot.

Page 19: Day 1

What Causes Accidents?

• Unsafe Condition is the physical state that is different from the acceptable, normal, or correct condition found on the job site.

• Examples…– Congested workplace– Poor lighting– Excessive noise

Page 20: Day 1

What Causes Accidents?

• Alcohol and Drug Use are a major contributor to accidents on and off the job.–Many states prevent workers from collecting

insurance benefits if they are injured while under the influence of alcohol or illegal drugs.

– You should also be aware that some prescription drugs can affect performance as well. If you are taking prescription drugs, be sure you know how they can affect you.

Page 21: Day 1

What Causes Accidents?

• An Intentional Act is an attempt by someone such as a disgruntled or angry worker to deliberately cause an accident.

Page 22: Day 1

What Causes Accidents?

• An Unsafe Act is conduct that can lead to an accident. Unsafe methods are often easier or more convenient than doing something right. – This makes it easier to rationalize doing

something that is unsafe.

Page 23: Day 1

What Causes Accidents?

• Management System is when your employer and the construction site management must have a system in place to:– prevent accidents– identify conditions that can cause accidents– train employees in accident prevention.

• The absence of such a program is a management system failure

Page 24: Day 1

Housekeeping• Housekeeping is the process of keeping the job site

and your immediate work area neat and clean, will help a lot in preventing accidents.– The work area should be well lighted and have good

ventilation.– Tools, equipment, and materials should not be left lying

around for people to trip over.

• The major goal of housekeeping is to prevent accidents.

Page 25: Day 1

Video:Failure to Communicate

Page 26: Day 1

What Causes Accidents?

• Failure to Communicate means that workers and supervisors should never assume that others know what to do.– Safety information is most often communicated with

signs. – All work sites have specific markings and signs to

identify hazards and provide emergency information• 4 types of signs:– Informational– Safety– Caution– Danger

Page 27: Day 1

Sign Examples

Page 28: Day 1

Informational Signs

• color – blue• provide general information.• Examples:– No Admittance– No Trespassing– For Employees Only

Page 29: Day 1

Safety Signs

• color – green panel with white letters• give general instructions and suggestions

about safety measures.• Examples:– First-aid station– Emergency eye wash station– Evacuation routes–Material Data Safety Sheets (MSDS)– Exits

Page 30: Day 1

Caution Signs

• color – black panel with yellow letters• tell you about potential hazards or warn

against unsafe acts.• Examples:– Hearing and eye protection required– Respirators are required– Smoking is not allowed

Page 31: Day 1

Danger Signs

• color – red, black, and white• tell you that an immediate danger exist and

that you must take precautions to avoid an accident.

• Examples:– Defective equipment– Flammable liquids– Safety barrier– High voltage– Emergency stop button

Page 32: Day 1

Activity9 Causes of Accidents

Objective: To choose a cause of accidents and illustrate examples of the chosen cause.

Group Task: Prepare a Multi-Flow Map with 3 causes and 3 effects from one of the 9 causes of accidents (pp 1.3-1.9).

failure to communicate, rationalizing risk, unsafe conditions

Agenda:1. QOD and Measurements2. Basic Safety PP3. Video – OSHA Introduction4. Activity – OSHA Inspections5. Review

Standards:AC-IFOS-2. Understand and practice construction safety.

Page 36: Day 1

OSHA Regulations• Occupational Safety and Health Act of 1970.• Mission:– to save lives– prevent injuries– protect the health of American Workers

• Code of Federal Regulation (CFR)– 29 CFR Part 1910 – covers OSHA’s standards

for the general industry.– 29 CFR Part 1926 - covers OSHA’s standards for

the construction industry.

Page 37: Day 1

Video:OSHA Introduction

http://www.dol.gov/dol/media/webcast/20110420-osha-40/

Page 38: Day 1

OSHA Regulations• The General Duty Clause - invoked when a

standard does not address a hazard.• If the following elements are present , a general

duty clause citation may be issued:– The employer failed to keep the work place free of

hazard.– The hazard was recognized, but not corrected.– The hazard was causing, or likely to cause, death or

serious physical harm.– There was a feasible and useful method to correct the

hazard.

Page 39: Day 1

OSHA Regulations

• Employee Rights and Responsibilities– If a worker has been discriminated against for

asserting his or her OSHA rights, that person has 30 days from the time of the incident to file a complaint with OSHA.

– Your employer is required by OSHA to maintain your job-related medical records for 30 years after you leave employment.

Page 40: Day 1

OSHA Regulations• Inspections are conducted to insure employers are

compliant with standards. There are 6 types.– Immanent danger: conducted when workers face an

immediate risk of death or physical harm.– Catastrophic: performed after an accident that requires

hospitalization of 3+ people. Employers are required to report fatalities and catastrophes to OSHA within 8 hours.

– Worker complaint: conducted due to complaint by worker.

– Programmed: aimed at high-risk areas.– Follow-up: completed after citation to assure employer

has corrected citation.– Monitoring: used for long-term abatement follow-up and

to assure compliance with variances.

Page 41: Day 1

OSHA Regulations

• A competent person is someone who is capable of identifying existing and predictable hazards and has authorization to take prompt corrective measures to eliminate such hazards.– To help employers provide a safe workplace, OSHA

requires companies to provide a competent person to ensure safety of their employees.

Page 42: Day 1

OSHA Regulations

• There are three categories of on-the-job events: injuries, accidents, and incidents.– An incident is anything that could have caused and

injury or damage but, because it was caught in time, did not.

– An accident is anything that causes an injury or property damage.

– An injury is anything that requires treatment, even minor first-aid.

Page 43: Day 1

Job Safety Analysis

• Job Safety Analysis (JSA) is one approach to hazard evaluation

• In a JSA, the task at hand is broken down into its individual parts or steps and then each step is analyzed for its potential hazards.

• For example in a Fall Protection Work Plan– Recognize Hazards– Provide Solutions– Identify Procedures– Define Training

Page 44: Day 1

Video:Job Safety Analysis – Fall Protection

Page 45: Day 1

Hazard Evaluation

• Risk assessment is a measure of the probability, consequence and exposure related to an event.

• Components:– Probability is the chance that a given event will

occur.– Consequences are the results of an action,

condition or event.– Exposure is the amount of time to which

someone or something is exposed.

Page 46: Day 1

Activity:OSHA Inspections

Objective: List important facts about 5 of the 6 types of OSHA inspection.

Group Task: Prepare a Tree Map to list important facts about 5 of the 6 types of OSHA inspection. Be prepared to present work to the class. (pp. 1.11)

OSHA Regulations• The 4 high-hazard area

Page 52: Day 1

OSHA Regulations• The 4 high-hazard area– Falls from elevation are accidents involving

failure to properly use appropriate fall protection.– Struck-by accidents involve unsafe operation

equipment, machinery, vehicles i.e. unsafe rigging operations.

– Caught-in accidents involve unsafe operation equipment, machinery, vehicles i.e. improper procedures at a trench site.

– Electrical shock accidents involve contact with overhead wires, use of defective tools, or improper ground fault protection.

Page 53: Day 1

Video:4 High Hazards

Page 54: Day 1

Personal Fall Arrest Systems (PFAS)

• A PFAS consists of a body harness, lanyards, lifeline, connecting devices, and anchor points.

• Always have your personal fall arrest system, PFAS, inspected monthly by a competent person.

Page 55: Day 1

Personal Fall Arrest Systems (PFAS)

• The lanyard attaches to the D-ring. The D-ring or support point on a safety harness should be placed to the rear, between your shoulder blades.

• A dual lanyard is an excellent method to enhance safe work operation.

Page 59: Day 1

Fall Protection• Any opening in a wall or floor is a safety hazard. These

openings can be guarded or they can be covered.• Railings are used across wall openings or as a barrier

around floor openings to prevent falls.• Warning barricades alert workers to hazards but

provide no real protection.– Warning barricade tape colored red means danger and no

one can enter.– Yellow signifies caution and allows entry. A yellow and

purple sign is used to indicate a radiation hazard.• Protective barricades give both a visual warning and

protection from injury. No one should be able to get past a protective barricade.

Standards:AC-IFOS-2. Understand and practice construction safety.

Page 66: Day 1

Video:Fall – Ladder 1

Page 67: Day 1

Ladders

• Ladders are used to perform work in elevated locations.

• Metal ladders conduct electricity and must not be used around electrical equipment or wiring.

• Types:– Straight ladders– Extension ladder– Stepladder

Page 68: Day 1

Ladders

• Ladders should be secured at the bottom and top to prevent accidental movement.

Page 69: Day 1

Ladders

• Ladders are used to perform work in elevated locations.

• Metal ladders conduct electricity and must not be used around electrical equipment or wiring.

• Do not carry tools while climbing a ladder; use a hand line or tag line.

• Types:– Straight ladders– Extension ladder– Stepladder

Page 70: Day 1

Ladders - Straight

Page 71: Day 1

Ladders - Straight

• Straight ladders consist of two rails, rungs between the rails, and safety feet on the bottom of the rails.

• Using straight ladders– If you are going step off a ladder onto a platform

or roof, the top of the ladder should extend at least 3’ feet above the point where the ladder touches the platform, roof, side rails, etc.

Page 72: Day 1

Ladders - Extension• Extension ladders are actually two straight ladders.

They are adjusted so you can adjust the overlap between them and change the length of the ladder as needed.

• Using an extension ladder– 4 :1 Ratio – The base needs to be set-back 1’ for each 4’

of length to the upper support point.– 3 Point Contact - Either have both hands and one foot or

two feet and one hand touching the ladder at all times.– The highest safe standing level on an extension ladder is

the 4th rung from the top. Never climb over the 4th rung from top.

– Check to make sure the section locking mechanism, rung lock, is fully hooked over the desired rung.

Page 77: Day 1

Ladders - Step

• Step ladders are self-supporting ladders made of two sections hinged at the top.

• Using an step ladder–When positioning a step ladder, be sure that all

four feet are on a hard, even surface.

Page 78: Day 1

Video:Fall – Ladder 1

Page 79: Day 1

Stairways

• Stairways are also routinely used on construction sites where there is a break in elevation of 19” or more, and no ramp, runway, sloped embankment, or personal hoist is provided.

• OSHA requires that at least five foot-candles of light be available in stairways.– An example of an unsafe condition on a jobsite is

inadequate lighting in a stairway.

Page 80: Day 1

Review

• How far should a ladder extend past a platform?• What is the highest safe standing level on an

extension ladder?• What should be used to transport tools from one

floor to another?• What is the 4:1 ratio referring to in ladder safety?• What is 3 point contact referring to in ladder safety?• What is an example of an unsafe condition?

Standards:AC-IFOS-2. Understand and practice construction safety.

Page 82: Day 1

Video:Scaffolding

Page 83: Day 1

Scaffolds• Scaffolds provide a safe elevated work platform for

people and materials• Two basic types of scaffolds are commonly used in

construction:– Manufactured scaffolds– Rolling scaffolds

• Scaffolds are made of– painted steel– stainless steel– aluminum.

Page 84: Day 1

Scaffolds• OSHA regulations provide for a system of tags to show

the status of scaffolding.– A green tag means the scaffold is okay for use.– A yellow tag means the scaffold can only be used with a safety

harness and lanyard because it lacks some safety feature.– A red-tagged scaffold may not be used because it is being

assembled or taken down.• If a scaffold is more than 10’ high, it must have top rails,

mid-rails, and toe-boards, and all connections must be pinned.

• Cross-bracing is also required, and the work area must be completely planked.

• A competent person must inspect a scaffold before it can be used.

Struck-by Hazards

• Account for 18% of construction fatalities.• Primary Causes:– Vehicle and Equipment Strikes– Falling Objects– Flying Objects

Page 89: Day 1

Vehicle and Equipment Strikes• Most common cause of accidents involving

highway workers.• When working on the ground near moving vehicles:– Never get into the operator's blind spot.– Keep off equipment unless authorized.– Wear reflective or high visibility vest

• When operating equipment on the job site:– Always wear a seatbelt– Look to the rear and sound the horn before backing up. If

your rear vision is blocked get a signaler to direct you.– Turn off the engine and set the breaks before you leave

the vehicle.

Page 90: Day 1

High Visibility Vest

• Wearing a reflective or high visibility vest is the best way to protect yourself when working near moving vehicles and equipment.

Page 91: Day 1

Falling Objects

• Workers on construction sites are at risk from falling objects. Avoid standing beneath any load on a crane or lift, and wear a hard hat at all times.

• Use toe-boards, debris nets, catch platforms, or canopies to catch or deflect falling objects.

• To prevent stacked material from falling over, never stack material higher than a 4:1 height-to-base ratio.

Page 92: Day 1

Video:Struck-by: Cranes

Page 93: Day 1

Flying Objects• Power tools and activities such as pushing,

pulling or prying can cause objects to become airborne.

• Chipping, grinding, brushing or hammering can cause objects to become airborne.

• To protect against flying objects…– Use eye protection i.e. safety goggles, face

shields.– Inspect tools to make sure protective guards are

in good condition.

Page 101: Day 1

Caught-In-Between Hazards

• Congested work sites, heavy equipment, and multiple trades can contribute to caught-in-between hazards.

• Construction workers often have to work in trenches or excavations, where cave-ins and falling objects are common hazards.

• Primary Causes:– Trench/Excavation Collapse– Rotating Equipment– Unguarded Parts

Page 102: Day 1

Caught-In-Between Hazards

• Excavation vs. Trench– An excavation is any man-made cut, cavity,

trench, or depression formed by the removal of earth or soil.

– A trench is an excavation that is deeper than it is wide, and usually not wider than 15'.

• Hazards include…– Cave-Ins–Water Accumulation– Falling Objects– Collapse of Nearby Structure

Page 103: Day 1

Video:Trench

Page 104: Day 1

Caught-In-Between Hazards• Soil Type is a key factor in determining the type of

Protective System necessary to ensure that the trench will be safe.

• To be safe, treat soil as if it is type C soil unless proven otherwise.

• Trenches and excavations must be inspected at least daily by a competent person.

Page 105: Day 1

Caught-In-Between Hazards• 4 Types of Soil Types– Solid Rock

• Excavation walls stay vertical as long as the excavation is open.– Type A Soil

• Fine grained and cohesive. Particles to small to see with the eye. Clay and Caliche

– Type B Soil• Angular rock, silt, and similar soil.

– Type C Soil• Course grained, granular. Particles are visible to the naked eye.

Sand, Gravel

Page 106: Day 1

Caught-In-Between Hazards

• Protective systems protect workers from cave-ins, materials that can fall or roll into an excavation, and collapse of adjacent structures.

• Sloping and benching are similar forms of trench protection that cut away and slant the excavation face.

• Benching systems cannot be used in type C soils, because they will not hold the bench properly and will collapse.

Page 107: Day 1

Caught-In-Between Hazards

• Sloping - a method in which the sides of an excavation are cut back to a safe angle using relatively smooth inclines

Page 108: Day 1

Caught-In-Between Hazards

• Benching – similar to sloping, but instead of smooth inclines, the sides of the trench wall are cut back using a series of steps.

Page 109: Day 1

Caught-In-Between Hazards

• Both systems call for a safe angle called the maximum allowable slope (MAS).

• Type A soil allows the steepest slope, while type C soil allows the shallowest slope. – Type A Soil: 3/4 – 1, or 53 degrees– Type B Soil: 1 to 1, or 45 degrees– Type C Soil: 11/2 to 1, or 34 degrees

Type A Type B Type C

Standards:AC-IFOS-2. Understand and practice construction safety.

Page 115: Day 1

Caught-In-Between Hazards• Many trenches are in narrow places, so sloping and

benching are not options. • In these situations, support systems like shoring or

shielding must be utilized.• Shoring vs. Shielding• Shoring consist of plating held firmly in place

with expandable braces.• Shielding structures, or trench boxes, are placed

inside trenches or excavations, and are strong enough to protect workers in the event of a cave-in.

Page 116: Day 1

Caught-In-Between Hazards

• Shoring structure vs. Shielding Structure

• Soil, materials and equipment should be placed at least 2’ from the edge of the excavation.

Page 117: Day 1

Caught-In-Between Hazards

• Keep all materials and heavy equipment at least 2' from the edge of the excavation.– Barricades may be required to contain falling

material. • Workers must be able to safely enter and exit

a trench using a stairway, ladder, or ramp. There must be an exit every 25' for every trench over 4' deep.

Electrical Safety Guidelines• The three-wire system is one of the most common

safety grounding systems used to protect you from accidental electric shock. – The third wire is connected to a ground.

• With every power tool, use an assured ground program or GFCI.– Double insulated cords are also effective in preventing

shocks when using power tools.

• Use some sort of a Ground Fault Circuit with every tool. They are designed to shut off electrical power within 1/40 of a second.

• The following is found on an MSDS:– Emergency first-aid procedures–Manufacturer contact information– Identity of the substance– Special control measures

Page 138: Day 1

Exposure• Definition: refers to contact with a chemical,

biological, or physical hazard.• Types of exposure hazards:– Lead – toxic metal– Asbestos – prolonged exposure can cause lung

cancer, asbestosis, and a cancer called mesothelioma.

– Silica – causes silicosis and lung cancer– Bloodborne Pathogens – transmitted by contact

with an infectious person’s blood– Chemical Splashes – in the event that this

happens use shower or eyewash station

Proximity Work

• Proximity work refers to work done near, but not in direct contact with a hazard such as hot piping, energized electrical equipment, operating machinery, pressurized or high temperature systems

• Barricades may be needed to avoid contact with these hazards, and special precautions may be needed during rigging operations to prevent objects from falling on the hazard.

Page 145: Day 1

Proximity Work

Page 146: Day 1

Welding and Cutting Hazards

• Welding can create an intense arc capable of damaging the eyes of anyone looking directly at it.– Proper eye protection, including flash goggles, must

be worn by everyone in the vicinity of arc welding. – When gas welding, welders are required to wear

tinted goggles with a filter lens of not less than No. 4• UV radiation from a welding arc can cause flash

burns to the eyes and skin. • Welding shields may be needed to protect

workers near the welding activity.

Page 147: Day 1

Welding and Cutting Hazards

• Different hoses are used for different gases.– The fuel gas hose is usually red, but may be

black. Its coupling nut has a left-hand thread, which is the opposite of the usual thread pattern.

– The oxygen hose is green and has a right-hand thread nut for connecting the torch.

• Look for charred on hoses. Charred sections of a welding hose may have been caused by flashback, result of welding flame flaring up.

Heat Stress• Heat stress occurs when abnormally hot air or high

humidity prevent your body from cooling itself fast enough.

• Results of heat stress:– Heat cramps – muscular pains and spasms caused by

heavy exertion.– Heat exhaustion – occurs when people exercise heavily

or work in a warm, humid place where body fluids are lost through heavy sweating.

– Heat stroke – is life threatening and occurs when the body-temperature control system, which produces sweat to cool the body, stops working.

Page 151: Day 1

Cold Stress

• Cold Stress occurs when your body temperature drops just a few degrees below normal, which is about 98.6°F.

• Results of Cold Stress– Frostbite – a dangerous condition that can have

lifelong effects on your body by loosing fingers, hands, limbs, etc.

– Hypothermia – a serious, potentially fatal condition and you do not have to be below freezing to be at risk.

Confined Space

• A confined space is one that is large enough to work in, but has limited means of entry and exit, as well as limited ventilation.

Page 159: Day 1

Permit-required confined space

• A permit-required confined space is one that has been evaluated by a qualified person and found to have actual or potential hazards, therefore, a written permit is required to enter such spaces.

• Confined spaces may contain hazardous fumes. Or, the work being done, such as welding or metal cutting, may introduce hazardous fumes.

Construction Ergonomics

• Ergonomics is the study of the physical impact that work-related movements, motions, and postures have on workers.

• Repetitive motion and constant vibration can cause injuries.

• Lifting is a six-step process that uses the muscles of the legs to avoid back injury.

Fire Hazards

• Fire is a potential hazard on any construction site.

• A fire needs fuel, heat, and oxygen to start. Fuel is any material that will burn, and oxygen is always available in the surrounding air.

• Heat is any action that will raise the fuel's temperature to the flash point, which starts the fire.
