FE FE Emergency Response & Extinguisher Selection 2

Question 1

When is it appropriate for a trained occupant to attempt to fight a fire with a portable extinguisher?

Accepted Answer

Only when the fire is small, confined, the alarm is activated, an exit is behind them, and they are trained

Answer

Occupant use is appropriate only for small, incipient-stage fires when conditions are safe: alarm active, exit available, and the person is trained.

Question 2

A fire in a propane storage area is best addressed with which type of extinguisher?

Accepted Answer

Class B dry chemical (BC or ABC) extinguisher

Answer

Propane is a flammable gas (Class B fuel), so a BC or ABC dry chemical extinguisher is the correct choice.

Question 3

Why should ABC dry chemical extinguishers generally NOT be used in a restaurant kitchen to suppress a grease fire?

Accepted Answer

ABC dry chemical does not cool the oil and the fire can re-ignite; wet chemical is required

Answer

ABC dry chemical can momentarily knock down the flames but does not cool the oil below its ignition temperature, allowing the fire to re-ignite.

Question 4

What is the most important safety rule when using a CO2 extinguisher in a confined space?

Accepted Answer

Evacuate the area immediately after use — CO2 displaces oxygen and creates an asphyxiation hazard

Answer

CO2 displaces oxygen and in an enclosed space can cause unconsciousness or death; all personnel must evacuate immediately.

Question 5

Which type of extinguisher is most appropriate for a printing facility with large quantities of paper (Class A) and ink solvents (Class B)?

Accepted Answer

ABC multipurpose dry chemical extinguisher

Answer

ABC multipurpose dry chemical addresses both Class A (paper) and Class B (solvent) hazards, making it the correct choice for mixed-hazard facilities.
