2. GENERAL GUIDELINES
Review these guidelines to ensure that the current operating procedures do not result in
hazardous situations. Although all hazards may not be able to be eliminated, the
following guidelines can be used to identify hazards so that the proper training,
operating procedures, and safety equipment can be implemented.
System operators should fully review the documentation supplied to gain an
understanding of the system functions.
When reading the manual, also take note of the “caution” and “warning” statements.
3. OPERATING SAFETY CONSIDERATIONS
The following operating safety considerations are applicable to most testing systems.
The user is required to read each items below and determines if it is applicable to the
testing system. The user is also required to obtain and review all safety instructions on
specific testing equipment used in the system.
Emergency stops
Determine the location of system emergency stop buttons to allow for quick emergency
stops.
Stay clear of testing system
Never allow bystanders to touch specimens or equipment while the system is operating.
Protective enclosures
If testing with internally pressurized chambers or brittle materials, protective enclosures
are recommended.
Effects of control adjustments
Do not make mechanical or software adjustments to testing system unless you know
exactly how the adjustment will affect system operation. In many cases a slight
adjustment can throw the system out of calibration. Consult an experience user or
supplier when in doubt about any adjustment procedure.
15
Interlock devices
Interlock devices should always be used and properly adjusted. Test all interlock
devices immediately before each test. Because of the possibility of operator error,
system maladjustment, or component failure, interlock devices cannot be totally relied
on to protect user, test specimen or test equipment. Thus, standard precautions about
staying clear of the ram should always be followed.
Gain adjustments
If operating the system in force or stress control, adjust the active Gain control to a
value known by experience to be stable for the particular system in use. Otherwise, the
possibility of violent instability should be anticipated when the test specimen comes in
contact with the system ram.
Avoid servo valve silting
Due to servo valve silting, an actuator can develop random instability or erratic
operation at unusually low hydraulic pressures, especially if the system uses large servo
valves or the hydraulic fluid is dirty.
Stay clear of loading piston
When system power is on, stay clear of each end of the actuator piston rod. The area
on the base plate used for component installation should be worked around with caution.
Never place any part of your body between the actuator piston rod and base plate when
the hydraulic/pneumatic pressure is on. Due to test specimen failure or operator error,
the actuator could unexpectedly react and cause personal injury.
System operation by transducers
If the system is under the control of a transducer, be certain that the transducer is not
bumped accidentally. This could cause the ram or other system components to move
suddenly. For example, if the test is deformation-controlled and the LVDT is bumped,
sudden movement of the ram may occur.
16
Dangers due to sudden system movements
High forces and rapid motions are usually presents in testing systems. Unexpected
actuator responses can be very dangerous. Likely causes of dangerous actuator
reactions are operator error and equipment failure due to damaged or abused
equipment. An actuator piston rod that reacts suddenly can strike an operator installing
a test specimen or damage the load cell or expensive components. For the above
reasons, anyone who operates, maintains, or modifies the system should read all
provided manuals to acquire a thorough knowledge of the system‟s operating
characteristics.
Loss of control feedback signal
If the control feedback signal is interrupted during operation, the controller senses an
error. The actuator will attempt to correct the error by stroking at maximum velocity until
it reaches an internal or external mechanical limit. The external mechanical limit may be
any type of obstruction that is in the path of a stroking actuator (such as tools,
specimens, or hands). Be aware that the full force of the actuator will be applied to an
external mechanical limit or obstruction. The only effective way to minimize the static
force capability of a system is to reduce the system hydraulic/pneumatic pressure.
The error detectors in the controller minimize the potential for specimen or equipment
damage caused by loss of feedback or larger than normal feedback errors. The error
detectors and can fault due to operator or component failure.
Electrical power failures
The failure or shutoff of electrical power to the testing system when pressure is being
applied can cause considerate and unpredictable actuator reaction. Under these
conditions, loss of electrical power on servo controlled systems will generally cause the
actuator to stroke at maximum velocity in either direction or, if a specimen is attached,
to apply full tensile or compressive force.
Many systems contain hydraulic/pneumatic accumulators that store enough energy to
temporarily operate the actuator at full force capacity even when the
hydraulic/pneumatic pressure is shut off. For this reason, the usual interlock devices will
not prevent hazardous actuator stroking.
17
Laboratory Safety
The geotechnical laboratory provides many advanced apparatus for soil & rock
laboratory testing. However the operator's lack of knowledge can cause a serious
accident. Make sure to understand the purpose of the research fully before you start the
experimental work. You also need to have a good knowledge of materials and
apparatus.
A．Make your area tidy and organized
don‟t put unnecessarily things in the laboratory. The area must be kept tidy and
organized. Clean the area immediately after the experiment. Follow the instruction when
you abandon waste (combustibles, incombustibles, soils should be separated).
B Put on proper protection
Wear appropriate laboratory clothes and put on necessary protection. A helmet, hard
shoes and gloves are recommended when you use a crane or large apparatus.
C．Conduct experiments in proper attitude
Lack of seriousness during experiments may lead to failure or even accident. You must
perform experiments in serious manner.
D．Carry out tests in good condition
You should not perform experiments when you are unwell. Also you should not carry out
tests alone at night.
E．Emergency drill
Confirm the location of the exit, a fire extinguisher, and the way to handle it, in case of
the emergency. It is necessary to carry out emergency drill from time to time
18

10. Risk Management
Aim To identify all hazards associated with the acitivities or work in Geotechnics Laboratory
and applying adequate control measures to reduce risks, monitoring such risks for the
activity and communicating the risks to the users.
All faculty, staff and students need to adhere to adhere strictly to the risk management
in the form of Risk Assessment exercise. This is in compliance with the Workplace
Safety and Health Regulation and NTU‟s Health and Safety Policy.
Risk Management Methodology Activity Based Qualitative Evaluation Methodology was being adopted.
The hazard identification shall be carried out systematically by recording potential
hazards at to each interface for each sub activity.
Risk evaluation shall be carried out by assessing the severity of the potential hazards
and the likelihood of occurrence of the event causing safety, ill-health or unforeseen
event with on current controls in place.
Appropriate control measures shall be identified for all unacceptable risks. This risk
evaluation shall be used as a basis for prioritizing actions to control identified hazards
and thereby, minimizing safety and health risks.
The control of hazards and reduction of risks can be accomplished by following the
hierarchy of controls. Two or more controls can be implemented together to reduce the
risk impact.
Risk Management Process The risk management process involves:
Breakdown of the process involved in the operation.
Identification of the hazards associated with the materials and process. Hazards
associated with waste disposal, spill and other emergency procedures should also be
considered.
Assessment of the frequency of occurrence and the severity of each hazard in context
of the process and potential exposure.
35
Determine the risks according to the accepted risk matrix.
Controlling/reducing those risks to an acceptable level.
Communicating the risks to the users.
A feedback to monitor effectiveness over time and make corrections as required
furthering improving the process.
Safety Committee of Geotechnics Laboratory have been brainstorming Activity based Risk Assessment during our regular safety meetings. We identify the more critical activities in our laboratory and brainstormed together to identify the hazards, evaluate the risks and implement risk control. Principal Investigator, Project Supervisors or Faculty-in-charge will approve each activity. All Risk Assessment forms are filed in B2 Geotechnics Laboratory or B5 Geotechnics Workshop. They are indexed according to the Inventory of Work Activities, followed by the approved Activity-Based Risk Assessment Form followed by Risk Assessment User Record. All users of the identified activities will be briefed, risk highlighted and supervised when carrying out their activities. Contractors who are awarded to do maintenance or repair work will have to submit the risk assessment before commencement of duty. Risk assessment will be reviewed yearly. The next page shows the risk assessment form used in Geotechnics Laboratory

13. Workplace Incident Reporting &
Investigation
The Geotechnics Laboratory keeps a register of all accidents, whether major or minor,
including near misses. Reporting of incidents is done by filling out the Incident
Reporting Form and submitting it to the Laboratory Safety Co-coordinator. A copy of
the completed form will be kept in the laboratory
.
Submitted Incident Reporting Forms are reviewed by the Laboratory Safety coordinator
and action (if any) will be taken to prevent a similar reoccurrence. All Incident Reporting
Forms are to be presented to the School Safety Committee during Safety Committee
meetings. This allows for further discussion of the incident and for any preventative
measures to be taken.
Incident Reporting Forms can also be used to report any unsafe practices or situations
that may result in an accident.
Reporting of all accidents, including near misses, serves two main purposes:
It seeks to protect the injured person should complications subsequently arise. For
example, if at a later stage, a cut finger becomes infected, the report will provide
evidence of the injury and also additional protection when claiming insurance
compensation.
It enables problem areas and operations to be identified, so that corrective
measures can be taken before a serious accident occurs.
Steps to follow when reporting an accident
If an accident occurs in the Laboratory,
48
Step 1: Contact Laboratory Safety coordinator or any laboratory staff immediately.
Step 2: Laboratory Safety coordinator will inform Laboratory First Aiders. Laboratory
First Aiders will render first aid immediately and if further medical treatment is required,
will accompany the injured to see a doctor or call for an ambulance.
Step 3: Once the person is granted medical leave (> 3 days) or hospitalized (> 24hrs),
the School Safety Committee is required to inform Ministry of Manpower. The incident
reporting form can be found at www.mom.gov.sg.
Step 4: If the person meets with an accident and results in immediate death, the School
Safety Committee will report the case to MOM immediately after informing the Chair or
Acting Chair.
If the accident occurs after office hours or during weekends, the injured should exercise
common sense and discretion on the seriousness of the injury. Proceed to seek
professional medical treatment if necessary and inform the laboratory staff as soon as
possible.

14. Use of Personal Protective Equipment
(PPE)
All activities that required Personal Protective Equipment ( e.g. laboratory work ,
fieldwork or manual handling ) must have a risk assessment completed prior to the
commencement of the work. The risk assessment should stipulate what personal
protective equipment should be employed.
Staff running laboratory classes are required to bring attention of students ( on class
handout whenever possible ) any hazards involved with their work and any specific
safety procedures such as the use of Personal Protective Equipment, etc.
Appropriate PPE must be worn relative to the risks associated with the experiments
being conducted in Geotechnics main Laboratory, Geotechnics Research Laboratory
and Geotechnics Workshop.
1. Foot Protection: Covered shoes must be worn at all times when working in the Geotechnics main Laboratory, Research Laboratory and Workshop. No open-toed shoes should be worn.
2. Hand Protection: Appropriate gloves must be worn when working with:
Hot objects, sharp or abrasive materials. E.g. transferring or handling of tray of soil sample from or to the conventional oven, as most of the conventional oven is set to 110 Degree Celsius.
3. Head Protection: Long hair should be tied back when starting work in the laboratories and workshop.
4. Respiratory Protection: Appropriate face mask must be worn when working with harmful material, sand that produce fine dust. E.g. the silica sand which when inhaling the fine dust over time could lead to health problem.
5. Hearing Protection: Earplug or earmuff must be worn when working with equipment that produced loud noise. E.g. the vibrating table for Relative Density Test, as exposing to the loud vibrating sound over a long period could lead to hearing problem.
6. Eye Protection: Appropriate safety goggles must be worn when necessary when working with:
High pressure, e.g. the 15 Bar pressure plate apparatus,
Machine that produce flying objects, e.g. the rock grinder and
Certain chemical which according to the Safety Data Sheet.

15. Fire Safety
Laboratory fires can by caused by bunsen burners, hotplate, electrical heating units, failure of unattended or defective equipment, or overloaded electrical circuits. Familiarize yourself with the operation of the fire extinguishers, emergency exits and evacuation routes where you work. In the event that the general alarm is sounded use the evacuation routes established for your area and follow the instructions of the Evacuation route. Once outside of the building, move away from the doors to enable others to exit.
The fire triangle
Fire cannot occur without an ignition source, fuel and an oxidizing atmosphere (usually air), the three elements that comprise what is called the "fire triangle":
Fire will not be initiated if any one of these elements is absent, and will not be sustained if one of these elements is removed. This concept is useful in understanding prevention and control of fires. For example, the coexistence of flammable vapours and ignition sources should be avoided, but when flammable vapours cannot be controlled
elimination of ignition sources is essential.
55
Classes of fire
Special powder is required.
Heavy duty type.
56
What are the fire hazards in the laboratory and how to
prevent them?
HAZARDS DON'TS DOS
Do NOT overload electrical outlet with too many plugs.
Use authority approved type of plugs and extension cords. Total appliances current consumption should not exceed the approved rating of one socket outlet.
Do NOT obstruct fire exit and escape passageways.
All fire exits and escape passageways shall be free from obstruction.
Smoking is prohibited in the campus.
Comply with NO SMOKING rules.
Do NOT wedge the fire door open.
All fire door shall be kept closed at all times.
57
Do NOT use the Electrical or M&E Riser compartments as storage areas.
All goods are to be kept in their appropriate storage area.
Do NOT use frayed electrical cable.
Ensure all electrical cable is well insulated and maintained.
Do NOT let unwanted items accumulate in your work area.
Unwanted items shall be removed and disposed in the authorised dumping site
58
16. Fire extinguishers
Fire extinguishers are rated as A, B, C or D (or combinations of A, B, C and D) for use against the different classes of fires. Familiarize yourself with the fire class ratings of the extinguishers in your work area so that you will know what types of fire you can attempt to extinguish with them.
Learn how to use the extinguisher in your lab, as there will be no time to read instructions during an emergency. Attempt to fight small fires only, and only if there is an escape route behind you. Remember to have the extinguisher recharged after every use:. If you do fight a fire, remember the acronym "PASS" when using the extinguisher:
59
How to use fire extinguisher?
Hold the extinguisher in an upright position.
Pull out the safety device which is fitted to prevent accidental discharge.
Aim the extinguisher nozzle at the base of the fire.
Keep a safe distance of about 1 to 1.5 metres away from the fire.
Press the top lever of the extinguisher.
Use a sweeping motion to allow the discharge to be directed over entire area of the fire.
60
Care and Maintenance of Fire Extinguisher
At least once a month (more often in severe environments) you should inspect your extinguisher. Ensure that:
a. The extinguisher is not blocked by equipment, coats or other objects that could interfere with access in an emergency.
b. The pressure is at the recommended level. On extinguishers equipped with a gauge (such as that shown on the right) that means the needle should be in the green zone - not too high and not too low.
c. The nozzle or other parts are not obstructed. d. The pin and tamper seal (if it has one) are intact. e. There are no dents, leaks, rust, chemical deposits and other signs of
abuse/wear. Wipe off any corrosive chemicals, oil, gunk etc. that may have landed on the extinguisher.
f. Fire extinguishers should be pressure tested (a process called hydrostatic testing) after 5 years to ensure that the cylinder is safe to use.
If the extinguisher is damaged or needs recharging, get it replaced immediately!
One more time: Recharge all extinguishers immediately after use regardless of how
much they were used.
61
Evacuations
In the event that the general alarm is sounded, follow the evacuation routes established for your area; do not use the elevators. Follow the instructions of the Evacuation Route. Once outside the building, move away from the doors to allow others to exit.

17. Fire Blanket
There are a few fire blankets in Geotechnics laboratory and
workshop located near the entrance of the door.
What are they?
They are made out of fire resistant fabric and are used to smother flames caused
through cooking or clothing fires. They should be located at the appropriate area where
everyone can reach. Fire blankets can only be used once. When a fire blanket is used,
please ensure that you discard the used blanket and replace it with a new blanket.
Do not remove or touch a fire blanket that has smothered any type of fire until
completely cool.
Ensure that the source of heat is turned off once the blanket has been placed on
the flames.
Always place the blanket carefully over cooking fat fires (do not throw)
In circumstances of a clothing fire, wrap the victim in the blanket and roll them on
the ground.
Do not use a fire blanket on electrical fires.
64
Instructions for Use of a Fire Blanket To use a fire blanket:
Pull the tabs to release the blanket; Shake it open and, holding the tabs, cover hands with the blanket ends; Place the blanket carefully over the vessel (eg frypan) to contain the fire; The source of heat (eg gas ring) should then be turned off and the fire blanket left
in place until cool and the fire brigade called; Under no circumstances should the blanket be lifted until completely cool.
Advantages
Quick to apply Light Easy to maintain Cheaper than extinguishers
Disadvantages
To use on a fire, you have to move close to the fire, and your hands are particularly vulnerable
You can only use on a very small and contained fire You probably only get one go at extinguishing the fire - if you fail to put it out, you
can't retrieve the blanket
65
How to use Fire Hose Reel
Turn on the hose reel valve before releasing the hose reel.
Run out the hose.
Turn on water at nozzle and direct the stream at the base of the fire.
66
18. Electrical Safety
Electrical Hazards
The major hazards associated with electricity are electrical shock and fire. Electrical shock occurs when the body becomes part of the electric circuit, either when an individual comes in contact with both wires of an electrical circuit, one wire of an energized circuit and the ground, or a metallic part that has become energized by contact with an electrical conductor.
The severity and effects of an electrical shock depend on a number of factors, such as the pathway through the body, the amount of current, the length of time of the exposure, and whether the skin is wet or dry. Water is a great conductor of electricity, allowing current to flow more easily in wet conditions and through wet skin. The effect of the shock may range from a slight tingle to severe burns to cardiac arrest. In addition to the electrical shock hazards, sparks from electrical equipment can serve as an ignition source for flammable or explosive vapors or combustible materials.
Preventing Electrical Hazards
There are various ways of protecting people from the hazards caused by electricity, including insulation, guarding, grounding, and electrical protective devices. Laboratory workers can significantly reduce electrical hazards by following some basic precautions:
Inspect wiring of equipment before each use. Replace damaged or frayed electrical cords immediately.
Know the location and how to operate shut-off switches and/or circuit breaker panels. Use these devices to shut off equipment in the event of a fire or electrocution.
Limit the use of extension cords. Use only for temporary operations and then only for short periods of time. In all other cases, request installation of a new electrical outlet.
Multi-plug adapters must have circuit breakers or fuses. Place exposed electrical conductors (such as those sometimes used with
electrophoresis devices) behind shields. Minimize the potential for water or chemical spills on or near electrical
equipment.
67
Things we must not do to prevent electrical fires
DO NOT use extension socket as a permanent wiring, especially in the
laboratories & workshop. Extension sockets are not to be used outdoors.
Use extension sockets for low current appliances; the total rated current for such
extension should NOT exceed 13A.
DO NOT use extension sockets if the rated current of the appliances is more
than 13A.
Check the equipment and appliance regularly by service agent. If the equipment
had not been used for some time, have them checked before using.
Conduct regular safety inspection of work area and office to include sockets,
connecting wires and extension sockets.
Check equipment, if there are frequent electrical trips; do not turn on the
equipment until it has been checked.
Maintain good housekeeping. Keep all combustible and flammable materials well
away from all electrical outlets and connections.
Do not attempt to repair any sockets and equipment unless you are trained.
Electrical work must be done by a licensed electrician.
SWITCH off any equipment when not in use; preferably at the socket. They
should be done at the end of the working day. Avoid putting equipment on „stand
by‟ or „on‟ mode.
Never pull out a plug when the current is flowing. Switch it off first.
Insulation
All electrical cords should have sufficient insulation to prevent direct contact with wires. In a laboratory, it is particularly important to check all cords before each use, since corrosive chemicals or solvents may erode the insulation.
Damaged cords should be repaired or taken out of service immediately, especially in wet environments such as cold rooms and near water baths.
Guarding
68
Live parts of electric equipment operating at 50 volts or more (i.e., electrophoresis devices) must be guarded against accidental contact. Plexiglas shields may be used to protect against exposed live parts.
Grounding
Only equipment with three-prong plugs should be used in the laboratory. The third prong provides a path to
ground for internal electrical short circuits, thereby protecting the user from a potential electrical shock.
Circuit Protection Devices
Circuit protection devices are designed to automatically limit or shut off the flow of
electricity in the event of a ground-fault, overload or short circuit in the wiring system.
Earth leakage circuit breakers and fuses are well-known examples of such devices.
Fuses and circuit breakers prevent over-heating
of wires and components that might otherwise
create fire hazards. They disconnect the circuit when it becomes overloaded. This overload
protection is very useful for equipment that is left on for extended periods of time, such as stirrers,
drying ovens, vacuum pump and other electrical equipment.

71
20. Safety Guidelines for FYP Students
Working in Geotechnics Laboratory
Students are advised to adhere to the following safety rules when working in the Geotechnics Laboratory and Workshop at all times:
Always observe all safety measures when operating any equipment, e.g. wearing of goggles, gloves, safety boots, ear plugs, etc.
Slippers, sandals and open-ended shoes are prohibited in the laboratory and workshop.
When operating moving or turning machines, students with long hair must tie them up.
It is very important to inform the laboratory staff when using any high-risk equipment.
Keep the working space tidy and avoid having any loose or unwanted items lying around.
Students should never work alone or when no one is around. Always make sure that someone knows where or what you are doing in the laboratory/workshop.
If there are strong reasons for the students to carry out their projects after office hours, approval must be obtained from the project supervisor and staff-in-charge (SIC). For such cases, booking form will need to be filled in and be submitted 7 (seven) days in advance to the laboratory staff. During their overtime, there must always be two students present, at all times, during such occasions. The guidelines for working after office hours will be briefed by the laboratory staff for first overtime and, subsequently, no briefing will be conducted. A key, to be shared among the overtime group, will be issued to students to gain access into the laboratory or workshop.
Due to security reason; students, who do not have overtime booking, are required to leave the laboratory/workshop by 5:45 pm (Monday – Thursday) and 5:15 pm (Friday).
72
21. Precaution when working with some
common laboratory equipment
Use of Pressure Vessels High pressure operations should be performed only in pressure equipment appropriately
selected for the operation, properly labeled and installed, and protected by pressure
relief and necessary control valves.
Equipment must be strong enough to withstand the stresses encountered at the
intended operating pressures and must not corrode.
Safety operation procedures should be developed by the laboratory to manage the use
and operation of the pressure equipment. All persons involved in the use or operation of
pressure equipment must be trained prior to its use. Training should include awareness
of hazards associated with high pressure, safe operating procedures, emergency
procedures and the appropriate control measures required to ensure protection of
personnel, equipment and the environment.
Safety requirement for the use of high pressure equipment are as follow:
Only materials and equipment design to withstand high pressure shall be use in it
manufacture.
Safety valves and other methods of pressure release so that their operation
cannot injure people and damaged equipment.
Regular inspection must be certified.
Operators must be provided with and use of appropriate personal protective
equipment.
Ensure that individuals working with pressure equipment are adequately trained
to understand the hazards associated with high air pressure with good laboratory
practices.
73
Vacuum Apparatus
Vacuum work can result in an implosion and the possible hazards of flying glass, splattering chemicals and fire. All vacuum operations must be set up and operated with Careful consideration of the potential risks. Equipment at reduced pressure is especially prone to rapid pressure. Such conditions can force liquids through an apparatus, sometimes with undesirable consequences.
Personal protective equipment, such as safety gasses, goggles or face shields should be used to protect against the hazards of vacuum procedures.
Do not allow water, solvents and corrosive gases to be drawn into vacuum systems. Avoid putting pressure on a vacuum line to prevent stopcocks from popping out or glass apparatus from exploding.
When using a vacuum source, it is important to place a trap between the experimental apparatus and the vacuum source. The vacuum trap protect the pump and the piping from the potentially damaging effects of material, protect people who work on the vacuum lines or system and also prevents vapors and related odors from being emitted back into the laboratory or system exhaust. To prevent contamination, all lines leading from experimental apparatus to the vacuum source should be equipped with filtration or other trapping as appropriate.
High Pressure Vessels High pressure vessels can present a variety of hazards due to their pressure and /or contents. Statutory pressure vessels such as steam boiler, steam receiver, air receiver, refrigerant plant pressure receiver and cast-iron under fired vulcanize need to apply for approval before they are brought into use. For details as well as information on how to apply for approval, please visit the website athttp://www.mom.gov.sg/FAQs/OSHD/HazardousEquipment.htm
As for other high pressure equipments not classified under the statutory equipment above, you are advised to carry out a suitable risk assessment to identify the hazards in operating such equipment and to develop appropriate measures and control systems to address the risks in consultation with the Safety Officer. For guidelines on risks assessment and management, please visit the website at http://www.mom.gov.sg/OSHD/Resources/Guides/Guidelines/index.htm.
In the event that a high pressure line ruptures, quickly determine which of the high pressure lines has ruptured, close the appropriate valves.
All pressure vessels should be inspected and tested at intervals determined by the severity of the equipment usage. Visual inspections and running test should be done by authorized examiner every two years
