What is the standard mounting height for a fire extinguisher?

Answer 1

Portable fire extinguishers under 40 pounds should be mounted so that the top is no more than 5 feet from the floor; those over 40 pounds, within 3 1/2 feet. The bottom must be at least 4 inches from the floor, unless the extinguisher is on wheels. NFPA 1.

Answer 2

A portable fire extinguisher of 40 pounds or less should be mounted with the top no higher than 5 feet from the floor, and the bottom no less than 4 inches from the floor.

A larger extinguisher should be mounted with the top no more than 3 1/2 feet from the floor, unless it is on wheels.

NFPA 1: Fire Code

Answer 3

In the USA, NFPA 1 requires portable fire extinguishers to be mounted with their top no more than 5 feet from the floor, if under 40 pounds, no more than 3 1/2 feet (42 inches) if they are over 40 pounds. In both cases, the bottom of the fire extinguisher must be at least 4 inches from the floor, except for larger extinguishers mounted on wheels. NFPA 1: 13.6.8.1.3.8 (2009), with reference to NFPA 10: 6.1.3.8.
