Dry chemical extinguisher residue after use on electrical equipment should be:
Answer: Cleaned up promptly because it is corrosive to equipment
Dry chemical residue is corrosive and can damage electrical components; it must be cleaned up promptly after the fire and extinguisher use.
If a fire guard must use an extinguisher in a confined space, the key additional hazard is:
Answer: CO2 or dry chemical can displace oxygen and create an asphyxiation risk
In confined spaces, CO2 and dry chemical agents can rapidly displace breathable air, creating a serious asphyxiation hazard for anyone inside.
Under the NYC Fire Code, who is responsible for ensuring a portable fire extinguisher is present and serviceable at a torch operation site?
Answer: The permit holder or contractor supervising the hot work
The permit holder or supervising contractor is responsible under the NYC Fire Code for ensuring appropriate fire protection equipment is in place before torch operations begin.
Which statement about water mist extinguishers is correct?
Answer: They are safe on Class C electrical fires because pure water is non-conductive
Water mist extinguishers use deionized water that is non-conductive, making them safe for use on Class C fires involving live electrical equipment.
A fire begins in combustible debris directly below the area where torch work is occurring. The FIRST step for the fire guard is to:
Answer: Shout 'fire,' stop work, and discharge an extinguisher at the base of the flames
The immediate response is to alert everyone, halt torch operations, and attack the fire at its base with the extinguisher before it can grow.
After successfully extinguishing a fire with a dry chemical extinguisher, what critical follow-up step must the fire guard perform?
Answer: Watch for re-ignition and ensure the area is monitored for at least one hour
After extinguishment, the area must be monitored for reignition — dry chemical does not cool the fuel, which can re-ignite if still hot.
Which extinguisher is appropriate for a fire in a propane cylinder valve area during torch operations?
Answer: Dry chemical extinguisher rated B:C — to suppress the gas fire
A B:C-rated dry chemical extinguisher is appropriate for a propane gas fire at a valve; however, if the cylinder itself is involved or venting, evacuation is the priority.
