Extinguishers weighing 40 lbs or less must be installed at a height where the top of the canister is no more than what distance above the ground?

The requirement for extinguishers weighing 40 lbs or less to be installed with the top of the canister no more than 5 feet above the ground is based on accessibility and safety regulations. This specific height ensures that these extinguishers can be easily reached and operated by individuals in an emergency situation. The rationale behind this standard is to facilitate quick access during a fire incident, allowing users to effectively respond without needing special equipment or assistance.

This height also takes into consideration the average reach of adults and ensures that those who may be less mobile or may have other physical limitations can still access the extinguisher without undue strain. Proper placement at this height is crucial in maintaining safety protocols and ensuring compliance with fire safety standards.
