What is the minimum clearance required between the bottom of a fire extinguisher and the floor?

The minimum clearance required between the bottom of a fire extinguisher and the floor is 4 inches. This height is determined to ensure that the extinguisher is easily accessible for use in an emergency. It helps to prevent obstruction from debris or other objects on the floor which could hinder quick access. Additionally, positioning it above the floor prevents damage from moisture or cleaning activities, which might occur on the ground level. A clearance of this height also allows individuals to identify and access the extinguisher without bending down excessively, making it safer and more efficient during critical situations.
