What is the minimum distance from the floor that a fire extinguisher must be mounted?

The minimum distance from the floor that a fire extinguisher must be mounted is 4 inches. This requirement is important because it ensures that the extinguisher is accessible and operable in an emergency situation. If a fire extinguisher is mounted too low, it could be obstructed by debris or water in the event of a fire, making it difficult to reach. Conversely, if it is mounted too high, it could be out of the reach of some individuals, particularly children or those with disabilities. Thus, maintaining a height of 4 inches from the floor strikes a balance between accessibility and safety, making it easy for most people to locate and use the extinguisher during a fire emergency.
