FE Installation & Placement Flashcards

Which occupancy classification typically requires the greatest number of fire extinguishers per square foot?

Answer: Extra hazard

Extra-hazard occupancies require the highest density of extinguishers because of the greater amount and type of combustibles present.

When extinguishers are located in a cabinet, what visibility requirement must be met?

Answer: Location must be marked with a sign visible from 50 feet

NFPA 10 requires that the location of extinguishers in cabinets be identified with a sign visible from at least 50 feet.

How should a fire extinguisher be positioned in relation to potential hazards?

Answer: Along normal paths of travel and egress, near the hazard but not in it

Extinguishers should be placed along normal paths of egress so occupants can grab them while evacuating without entering the hazard area.

What is the maximum floor area per extinguisher for a light-hazard Class A occupancy under NFPA 10?

Answer: 11,250 sq ft

For light-hazard occupancies, NFPA 10 allows a maximum coverage area of 11,250 square feet per extinguisher for Class A hazards.

When should fire extinguisher location signs be used?

Answer: Whenever the extinguisher is not readily visible from normal approaches

Location signs are required whenever the extinguisher is not immediately visible from normal approaches to the area.

Which factor is NOT typically used to determine the required number and placement of fire extinguishers?

Answer: Color of the building interior

Interior color has no bearing on extinguisher placement; hazard class, area size, and travel distance are the determining factors.
