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

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.

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.

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.
