What is the maximum allowable clearance between the bottom of a fire extinguisher and the floor?

The maximum allowable clearance between the bottom of a fire extinguisher and the floor is 4 inches. This guideline is established to ensure that fire extinguishers are easily accessible in case of an emergency. When placed too high, especially in a stressful situation, it may be difficult for individuals to quickly reach or operate them. The 4-inch standard allows for adequate visibility and accessibility while also preventing the extinguishers from being too low where they could be obstructed or vulnerable to damage. Staying within these parameters enhances safety and ensures compliance with fire safety regulations.
