Damaged sprinkler heads can have a detrimental effect on the performance of sprinklers by affecting water distribution patterns, insulating thermal elements, delaying operation, or otherwise rendering the sprinkler inoperable or ineffectual. According to The Joint Commission’s 2010 Hospital Accreditation Standards for Life Safety, hospitals must provide and maintain systems for extinguishing fires. LS.02.01.35 Element of Performance 5 states, “Sprinkler heads are not damaged and are free from corrosion, foreign material, and paint.” The standard offers the following: (For full text and any exceptions refer to NFPA® 25-1998: 2-2.1.1.) Section 2-2.1.1 of NFPA® 25, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems states, “Any sprinkler shall be replaced that is painted, corroded, damaged, loaded, or in the improper orientation.” Note that sprinklers installed in concealed spaces such as abovesuspended ceilings do not require inspection.
