Author: Marty Ahrens
Issued: July 2017


Report highlights

  • Sprinklers were present in only 10% of reported structure fires in 2010-2014.
  • Most structure fires and fire deaths occurred in homes, but sprinklers were found in only 7% of all home fires.  Sprinklers were most likely to be found in institutional occupancies such as nursing homes, hospitals, and prisons or jails. 
  • The civilian death rate per 1,000 reported home fires was 81% lower in homes with sprinklers than in homes with no AES.
  • In three of every five incidents in which sprinklers failed to operate, the system had been shut off.
