F-02 Fire Extinguisher Use and Classification 2

Question 1

How frequently must portable fire extinguishers in a place of assembly receive a visual inspection?

Accepted Answer

Monthly

Answer

FDNY and NFPA 10 require monthly visual inspections of portable fire extinguishers to confirm they are charged, accessible, and undamaged.

Question 2

When using a fire extinguisher, at what part of the fire should you aim the discharge nozzle?

Accepted Answer

The base of the fire

Answer

Aiming at the base of the fire attacks the fuel source and is the most effective way to extinguish the fire rather than spraying the flames themselves.

Question 3

A fire extinguisher's pressure gauge needle is in the red zone below the green area. What action should the fireguard take?

Accepted Answer

Tag it out of service and report it for recharging

Answer

A gauge reading in the red undercharge zone means the extinguisher lacks sufficient pressure to operate effectively and must be removed from service and recharged immediately.

Question 4

According to NFPA 10, who is authorized to perform the annual maintenance inspection of portable fire extinguishers?

Accepted Answer

A licensed or trained fire extinguisher service technician

Answer

Annual maintenance must be performed by a trained and licensed fire extinguisher service technician who can verify internal components, pressure, and agent condition.

Question 5

A fire extinguisher has been partially discharged during a drill. What must happen next?

Accepted Answer

It must be recharged or replaced before being returned to service

Answer

Any extinguisher that has been used or partially discharged must be recharged or replaced immediately, as a partial charge may be insufficient to fight an actual fire.
