Fire Precautions
Design Stage
-
Enclosure of 2hr
fire resistance for stair cases and lift wells.
-
Wide staircases
and lobbies to permit orderly evacuation in emergency.
Pressurisation of these areas will keep them free of smoke.
-
Critical areas
such as refuge areas to be protected by fire proof doors.
-
Fire-lift for
exclusive use of fire fighters.
-
Electrical wiring
in metal conduits.
-
Emergency
switches at ground floor for disconnecting power, floor-wise.
-
In central air
conditioning (A/C) system, provide automatic fire dampers (in the
common duct) for each floor or occupancy.
-
Individual A/C
system for each occupancy or for each floor is preferred to
central A/C system.
-
Openings in the
cable passageways (from duct to floors) to be closed.
-
Alternate power
supply for staircase & corridor lighting circuits, fire lifts and
stand-by fire pump.
-
Fire detection
& alarm system, hose reels, wet risers, yard hydrant, automatic
sprinklers and water reservoir as per National Building Code.
Occupation
Stage
-
Minimise
combustible materials for furnishing. Use fire retardant
material for false ceiling, partititons and upholstry.
-
Develop a
simple, written fire safegy plan which should include precautions
for fire prevention at occupant's level, fire control by the
building maintenance/security team and the emergency plan covering
evacuation procedure.
-
All occupants
should know clearly how to identify/raise fire alarm, call fire
brigade, tackle fire and evacuate safely.
Maintenance Stage
-
Ensure good
maintenance of fire appliances.
-
Check
periodically availability of dedicated water for fire fighting.
-
Undertake fire
drills and mock exercise for evacuation.
-
Have stringent
controls against over loading of electrical circuits, accumulation
of chemicals and flammables, and storage of materials in the
staircases, lobbies and fire escape stairways.
During
Fire Emergency
-
Keep the doors
and windows shut to prevent ingress of heat and smoke.
-
Evacuate
without panic, but quickly. Do not waste time in collecting
things.
-
Do not use
lifts as they may malfunction.
-
If fire is in
an upper floor, proceed to lower floors and eventually to outside
the building. If fire is in a lower floor, use judgment and
decide the evacuation direction. Try to reach refuge area, if
provided in the building.
-
Remember that
floor level will be free from smoke for longer time.
