B. Emergency Procedures 1. Fire

Fire is one of the greatest potential hazards in the building and every effort should be

made to avoid the possibility of starting a fire. Examples of fire hazard include: bunsen

burner left on, water baths running dry, self igniting chemical mixture, electrical

equipment in poor maintenance (short circuits), and lack of precautions when handling

flammable solvents.

a) Fire Reporting Procedures

Notify

If you discover a fire, immediately shout “fire” to alert the personnel in the immediate

area. Go to the nearest fire alarm box and activate the alarm.

Evacuate

Evacuate from the immediate area or building. Call the Fire Brigade from a safe

location outside the immediate area. Only revisit the fire if it is safe to do so and two

or more people are present.

Isolate

If you are present when a fire breaks out and IF SAFE TO DO SO, you may attempt to

put out the fire and at the same time shout "fire" to alert other people in the area.

Prompt action will often prevent a small fire from becoming a major disaster. If the

fire is beyond control, close lab door(s) and corridor door(s) to contain the fire within

the area.

b) Fire Extinguishers

The following types of fire extinguishers are installed throughout the lab.

Type and Location Colour To Use For Use Against

Dry Chemical; located

prominently near the

main and emergency

exits

Blue Remove pin and

squeeze handle

General purpose,

Electrical Equipment

FAMILIARISE YOURSELF WITH THE LOCATION OF FIRE

EXTINGUISHERS AND THE HOSE REELS IN YOUR AREA.

3  

Please refer to Figure 1 for nearest emergency exits, do familiarise yourself with the location

of the emergency exits.

Figure 1.Escape Routes

4  

C. Evacuation Procedures When you hear the fire alarm sound the 2nd time you must leave the building

immediately through the escape route in the laboratory. Assemble at the designated

assembly point. Do not gather too close to the building.

DO NOT USE LIFTS. They may fail in an emergency.

1. Fire Alarm

Turn off all electrical equipment.

Close the windows.

Leave the laboratory/room and close the door.

Make sure all corridors and laboratory smoke doors are closed to prevent draughts.

Leave the building under the direction of the Floor Warden, using the stairs.

Assemble at Carpark D at Basement 5 of the N2 Block(Figure 2)

Note: If for some reason a warden is missing, any member of staff should be prepared

to take over.

2. Emergency Wardens

During normal working hours a Floor (Fire) Warden has been appointed to each floor.

All staff are required to co-operate and comply with their instructions during an

emergency and, if warden are absent, take over their role.

Responsibilities of Wardens

• Instruct all personnel to leave the building and assemble at Car park D at Basement

Level 5 of the N2 Block.

• Close the corridor and laboratory smoke doors.

• Ensure that all personnel are evacuated in times of emergency.

• Report to the Campus Warden or Fire Brigade, the location of any person left on

your floor, e.g. disabled persons and escorts, persons trapped.

3. Laboratory

In the event of the fire, laboratory staff should get students to stop their work, turn off

all electrical equipment and leave the laboratory by the designated exit. Staff should

shut all windows and doors if possible.

5  

D. Hazard Identification and Personal Protection

1. Potentially Hazardous Situation

All personnel are encouraged to report to the laboratory staff and laboratory Safety

Officer, any perceived or suspected hazardous situation or practice. CEE TGS Lab

Accident/Incident Report Form (Annex A) should also be completed and returned to

the laboratory Safety Officer or laboratory staff.

2. Smoking Control and Enforcement

Smoking is prohibited in the laboratory and the whole campus; staff/ student who

need to smoke must do so in the designated location at Level 2, inside the Yellow

Box.

As TGS Lab stores flammable material, it is banned to smoke in the lab; anyone

caught will be deal with according to NEA regulation.

First time offenders will be fined $200, while repeat offenders could be fined as much

as S$1,000 by the Authority

3. Running in the Building

Except in an emergency, do not run within the building. A collision with another

person carrying something could be very serious, and slipping on floors and stairs is a

common cause of injury.

4. Unsafe Condition Report

When anyone in the laboratory considers that there is a deficiency in the current

safety procedures, or further improvements could be made in certain areas, do raise it

up to the Safety Officer or laboratory staff.

- User should check that the revolving dome light is working before bring it

out to field.

- Care must be taken when working on overhead bridges or flyover, taking

care not to drop anything on vehicles passing below.

I. Electrical Safety

Electrical Hazards cause Electrical Shock, Fire, Explosion, Burn and Injury

a. Common Electrical Hazards & Prevention Causes of electrical accidents are due to ignorance, lack of maintenance and unsafe

equipment used. It is important that the labs prevent fire and shock hazards by

observing the following precautions:

1. Proper maintenance of the equipment.

2. Proper Notices / Signs (eg.: High Voltage sign)

3. Do not use extension cords for permanent wiring (extension cords should not

supply power to permanent equipment like refrigerators) and do not run

extension cords through walls.

4. Electrical cord used on equipment must be in good condition, not frayed or

cracked. Damaged cords must be removed or repaired, not taped over.

5. Multi-outlet power strips must have overload protection (circuit beaker) and

must not be connected to another power strip or extension cord.

6. Electrical cords and extension cords must plug directly into the wall without

adaptors. An electrician should do all repairs and modifications.

7. Note that just 40 mA DC or 6 mA AC 50 Hz can cause muscle contraction that

prevents release. In the process, 3 to 10% of the current goes through your heart

13  

and can cause fatal damage.

8. Above 300 mA DC or 70 mA AC 50 Hz will cause immediate cardiac arrest.

(Body resistance is approximately 500 ohms).

9. Cables used must be appropriate to their loading.

10. Either a fuse or a circuit breaker should provide protection against insulation

failure.

11. Prevent exposure of live terminals and use isolators.

12. Cables and conduits must be earthed as a legal requirement.

13. Do not handle any electrical connections with wet hands or when standing in or

near water.

14. Safety devices on electrical equipment must not be bypassed.

15. Disconnect electrical equipment from electrical outlets or circuits when being

adjusted, lubricated, moved, or cleaned.

16. Ensure cords are placed in areas where they are not exposed to physical

damage. They are not to run through doorways or ceilings, or placed under

carpets.

17. Under no circumstances should extension cords or electrical cords be spliced.

b. Electrical Equipment 1. All personnel must understand the relevant safety procedures before operating

any laboratory equipment and machinery. If in doubt, please ask the laboratory

staff.

2. When equipment is not being used, electrical leads should be disconnected and

neatly coiled beside the equipment or machine.

3. Should any electrical equipment suffer any damage (water, chemical spill),

arrange for it to be electrically checked by a qualified technician.

4. Repair or modification to all equipment capable of being connected to the

laboratory electrical supply shall be carried out only by authorised electrical or

mechanical workshop staff.

5. Electrical cables should be kept off floors to minimise hazards and to assist the

cleaners. If this is unavoidable then a ramped cover must be installed over or

the cables tied up to facilitate the movement of equipment and to minimise

accidents.

a. All works involving the electrical supply for the building, i.e. fittings,

fixed wiring, switchboards, etc., must be isolated from the mains.

14  

Labelling of the switches shall be carried out by Works and Services staff

from ODFM.

b. Circuit Breakers. When a circuit breaker has “tripped” to overload, the

circuit and its load must be checked by an authorised person before power

is restored.

c. Heating Equipment Safety. The main hazard of heating equipment is fire.

Ensure that no flammable solvents are used near an electrical switch or a

hot surface.

d. Laser Emission Safety. Do not look directly at unshielded laser sources;

appropriate eye protection must be worn.

6. Electrical and other general items of laboratory equipment must be cleaned,

examined for faults, and arranged to be repaired if necessary.
