Under what condition should a fireguard attempt to fight a fire with a portable extinguisher rather than evacuate?
Answer: When the fire is small, contained, and the exit is behind the fireguard allowing safe escape if needed
A fireguard should only attempt extinguishment when the fire is small and contained, they have the proper extinguisher, and an unobstructed exit is behind them for safe escape if the attempt fails.
A CO2 fire extinguisher discharges very cold gas. During use, a fireguard should avoid touching which part of the extinguisher?
Answer: The discharge horn or nozzle
The discharge horn of a CO2 extinguisher becomes extremely cold during use due to rapid gas expansion and can cause frostbite if held directly.
Which type of fire extinguisher leaves a corrosive residue that can damage sensitive electronics and computer equipment?
Answer: Dry chemical (ABC) extinguisher
Dry chemical extinguishers leave a fine powder residue that is corrosive and difficult to clean, making them harmful to sensitive electronics; CO2 or clean agent extinguishers are preferred for equipment rooms.
What is the purpose of hydrostatic testing performed on portable fire extinguishers?
Answer: To test the strength and integrity of the extinguisher cylinder under pressure
Hydrostatic testing subjects the extinguisher cylinder to pressures exceeding normal operating levels to detect cracks, corrosion, or metal fatigue that could cause a rupture.
A fireguard finds a fire extinguisher with a broken tamper seal and missing inspection tag. What is the proper action?
Answer: Report it for inspection and place it out of service
A broken seal and missing tag mean the extinguisher's serviceability cannot be verified; it must be removed from service and sent for inspection before being returned to use.
When should a fireguard immediately stop attempting to fight a fire and initiate evacuation?
Answer: If the fire grows beyond the initial small size or smoke begins to fill the area
If a fire grows, spreads, or smoke accumulates, the situation has exceeded what a portable extinguisher can handle and life safety requires immediate evacuation and FDNY notification.
How should a fireguard record the use or inspection of a fire extinguisher in a place of assembly?
Answer: Document it in the fire safety log, noting date, time, location, condition, and action taken
FDNY regulations require fireguards to maintain a written log of all inspections, equipment conditions, and incidents including any use of fire extinguishers, with date, time, and details.
