Fire extinguishers greater than 40 lbs should be mounted no greater than how far from the floor?

For fire extinguishers that weigh more than 40 pounds, the standard mounting height is set to ensure safety and accessibility. The maximum mounting height is 3.5 feet from the floor to the top of the extinguisher. This specification is crucial because heavier extinguishers can be cumbersome to handle, and positioning them too high could make it difficult for individuals, especially those who may not be as tall or strong, to reach them in an emergency.

Mounting extinguishers at or below this height also allows for easy visibility and identification in cases of an emergency, which is vital in a fire situation where every second counts. The requirement reflects safety regulations designed to accommodate a wide range of users who might need to access these vital firefighting tools quickly and effectively.
