Extinguishers weighing under 40 lbs must be mounted at a maximum height of how many feet above the floor?

For fire extinguisher mounting, the guidelines specify that extinguishers weighing under 40 pounds should be mounted no higher than 5 feet above the floor. This height is established to ensure that the extinguishers are easily accessible to individuals, particularly in an emergency situation.

Mounting extinguishers at this height ensures that they can be reached without excessive effort, which is critical during emergencies when time is of the essence and individuals may be under stress. In addition, placing them too high could make it difficult for people, especially those who are shorter or those with physical disabilities, to retrieve the extinguishers promptly.

The other options suggest heights that exceed the acceptable limit for safety and accessibility. Thus, the correct standard height of 5 feet strikes a balance between safety regulations and practicality, ensuring effective use during an emergency.
