Smoke Alarms in U.S. Home Fires
Marty Ahrens September 2009
Cost: $25.00 (free to the fire service). 95 pages. Order # USS04.
Report includes statistics on home smoke alarm usage, effectiveness, operationality, and home fire fatalities in fires with and without working smoke alarms.  Also includes home fire death rate with different combinations of fire protection equipment.  Brief discussion of literature on audibility and waking effectiveness.
Abstract: Almost all households in the U.S. have at least one smoke alarm, yet in 2003-2006, smoke alarms were present in only two-thirds (69%) of all reported home fires  and operated in just under half (47%) of the reported home fires. (“Homes” includes one- and two-family homes, apartments, and manufactured housing.)  Forty percent of all home fire deaths resulted from fires in homes with no smoke alarms, while 23% resulted from homes in which smoke alarms were present but did not operate. The death rate per 100 reported fires was twice as high in homes without a working smoke alarm as it was in home fires with this protection. Hardwired smoke alarms are more reliable than those powered solely by batteries.
These estimates are based on data from the U.S. Fire Administration’s (USFA’s) National Fire Incident Reporting System (NFIRS) and the National Fire Protection Association’s (NFPA’s) annual fire department experience survey.
