Q: Do fire extinguishers that are placed in patient care areas of a hospital have to be placed in a wall cabinet, or can they hang from the wall?
A: NFPA 10-2010 does not require extinguishers to be mounted in a wall-cabinet. They are permitted to be mounted on a wall without the use of a cabinet. But be aware that CMS limits all wall projections into the corridor to be no more than 4 inches, which the average 10-lb. extinguisher would exceed.
Consider the Oval brand of fire extinguishers, as they project less than 4 inches.
