How should a fire extinguisher be mounted for accessibility?

A fire extinguisher should be mounted not more than 5 feet off the floor to ensure accessibility for all individuals, including those who may not be able to reach higher placements. This height allows for easy identification and retrieval during an emergency situation. Keeping the extinguisher within this range also complies with safety regulations, ensuring that it is easily accessible without significant risk of injury from reaching too high or from obstructing access.

The other options do not meet the standard for accessible mounting heights. Mounting at shoulder height may not be universally accessible and could vary by individual height. A height restriction of 3 feet may limit visibility or accessibility in certain situations, while mounting at ceiling level would make it nearly impossible to reach in an emergency. Proper placement is crucial for effective fire safety and response.
