Building placement (NFPA 10)

In commercial buildings, portable fire extinguisher placement follows NFPA 10, not the DOT vehicle rules below. Every point on the floor must be within 75 ft of a Class A extinguisher. Mount the unit with its top no more than 5 ft above the floor and at least 4 in of floor clearance (NFPA 10 §6.1.3.8). A 2-A or larger extinguisher within 75 ft covers most light-hazard areas, but the required size and count are set by your authority having jurisdiction (AHJ).

Cabinet fit

At 4-1/4 in diameter and 16-3/8 in tall, it fits virtually any standard semi-recessed extinguisher cabinet, including both 5 lb and 10 lb cabinet tubs, with room to spare.

DOT Vehicle Size Recommendations

DOT 49 CFR §393.95 requires commercial motor vehicles to carry a UL-listed fire extinguisher. Minimum size depends on vehicle class and whether the load is placarded hazmat.
