The Life Safety Code® mandates that all automatic sprinkler and standpipe systems required by this Code must be inspected, tested, and maintained in accordance with NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. Section 2-2.1.1 of the 1998 edition states “Sprinklers shall be free of corrosion, foreign materials, paint, and physical damage and shall be installed in the proper orientation (e.g., upright, pendant, or sidewall). Any sprinkler must be replaced that is painted, corroded, damaged, loaded, or in the improper orientation.” The Appendix says that the conditions described above 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.
