At what maximum mounting height should extinguishers over 40 lbs be installed?

Fire extinguishers that weigh over 40 pounds must be installed at a maximum height of 3.5 feet from the floor to the top of the extinguisher. This guideline is established to ensure that individuals can easily access and operate the extinguisher in case of an emergency. The weight and size of larger extinguishers require that they are not mounted too high, as this could impede swift action during a fire incident. Proper installation height is crucial for effective emergency response, enabling users to retrieve extinguishers quickly and without additional assistance. The standards for mounting fire extinguishers are part of the broader safety regulations that promote rapid accessibility and safe operation, especially in high-stress situations like a fire.
