NFPA’s John R. Hall, Jr., March 2012
Includes statistics on how often sprinklers are reported in fires, by property use, and their estimated impact in reducing the average loss of life and property per fire. Includes statistics on performance, usage and reliability of sprinklers, as well as leading reasons when system fail to operate or operate but are ineffective. Also includes special study statistics on non-fire sprinkler activations.
The report cites an American Housing Survey that states that in 2009, 4.6% of occupied homes (including multi-unit) had sprinklers, up from 3.9% in 2007, and 18.5% of occupied home built in the previous four years had sprinklers. Of reported 2006-2010 structure fires, an estimated 9% showed sprinklers present. Sprinklers were reported as present in 55% of reported fires in health care properties. Manufacturing facilities (48%), hotels and motels (51%), prisons and jails (53%), and dormitories and barracks (53%), all had sprinklers reported in at least half of reported structure fires. In most other property uses, at least two-thirds of all reported fires were reported as sprinklers not present.
