NFPA Report Finds Higher Estimated Reliability of Fire Sprinklers

10/05/2005


The National Fire Protection Association (NFPA) has released an updated report with new evidence on the value of automatic fire sprinkler systems. The report finds sprinklers to be even more reliable than previously estimated in reducing U.S. fire deaths.

The report, “U.S. Experience with Sprinklers and Other Fire Extinguishing Equipment,” also confirms that the century-old technology remains underused, especially in the place where the risk of fire death is greatest, the American home.

The report states that when sprinklers are installed, the chances of dying in a fire are reduced by one-half to three-fourths, compared to fires where sprinklers are not present. Sprinklers are now estimated to operate in 93% of fires large enough to activate them. And for the first time, it is possible to document that nearly all sprinkler failures involve errors of human judgment, including 65% that occurred because the systems had been shut off prior to the fire.

Sprinklers appear to be present in most health care facilities, high-rise hotels and high-rise offices buildings and, to a lesser extent, in department stores and manufacturing facilities.

But most fires still occur in properties without sprinklers, says the report, and the systems remain especially rare in homes. NFPA estimates sprinklers are present in less than 1% of the reported fires that occur in one- and two-family dwellings and in less than 8% of reported fires in apartments. Where sprinklers are present in homes, their impact on life safety is as large as it has been in other properties where sprinklers have been long-established.
