Fire extinguishers greater than 40 pounds are installed not more than _____.

The correct installation height for fire extinguishers that weigh more than 40 pounds is a maximum of 3 ½ feet above the floor. This height requirement ensures that the extinguishers remain easily accessible to individuals in the event of a fire emergency. Since heavier extinguishers can be more challenging to handle, placing them at this height provides a balance between accessibility and safety. It also complies with safety standards that aim to prevent injuries while ensuring quick access to firefighting equipment. By maintaining this height, it allows individuals of varying physical capabilities to reach and operate the extinguishers effectively when needed.
