How high do the ‘Fire Extinguisher’ signs need to be installed above the extinguishers?
Chambers: OSHA only requires extinguishers be “identified.” While an extinguisher mounted on a wall may be clearly visible from up close, they may be blocked from view if a person is standing a distance away. Materials stacked on pallets or shelving could prevent the extinguisher from being seen, as could open doorways or parked equipment like forklifts. Therefore, it is usually best to install a sign (or other means of identification) above a portable fire extinguisher so its location can be identified from a distance in case it is obstructed from view. How high? Depending on job site conditions, there are many cases where the fire extinguisher sign (or other means of identification) needs to be placed very high (near the ceiling) above fire extinguishers (as opposed to right on top of it) to enable them to be located when the previously mentioned obstacles are present.
