Fire Safety Procedures Flashcards

Which condition makes it unsafe to fight a fire with a portable extinguisher?

Answer: The fire has grown beyond the initial ignition stage

Portable extinguishers are only appropriate for small, contained fires; a fire that has grown beyond the initial stage requires evacuation and fire department response.

What information must be posted on or near a pull station in most commercial buildings?

Answer: Instructions for use and building address

Pull stations must display clear operating instructions, and buildings must have their address posted to aid emergency dispatch.

What is the purpose of a fire assembly point (muster station)?

Answer: To account for all occupants after evacuation

Assembly points allow supervisors or wardens to take headcounts and confirm all occupants have safely exited the building.

Dry chemical extinguishers leave a residue. Which environment makes this residue particularly damaging?

Answer: Server rooms and data centers

Dry chemical powder can destroy sensitive electronics; CO2 or clean-agent extinguishers are preferred in server rooms.

Under NFPA 72, how far apart must smoke detectors be placed in a standard corridor?

Answer: No more than 30 feet apart

NFPA 72 requires smoke detectors to be spaced no more than 30 feet apart in corridors to ensure adequate coverage.

Which sign of fire behavior should cause a firefighter or occupant to immediately exit a structure?

Answer: Darkening, rolling smoke near the ceiling that suddenly reverses direction

Darkening, turbulent smoke that rolls back toward the floor is a warning sign of backdraft or flashover, requiring immediate evacuation.

What is the recommended position to take when crawling through a smoke-filled corridor?

Answer: Crawl low with face 12–24 inches from the floor

Smoke and toxic gases rise, so air near the floor is cleaner; crawling 12–24 inches off the floor balances breathable air and visibility.
