NFPA is aware of research indicating that sleeping children don't always awake when a smoke alarm activates. While this research is worrisome, we shouldn´t allow them to obscure the fact that smoke alarms are highly effective at reducing fire deaths and injuries.
NFPA would like to reaffirm the value of the smoke alarms already available to protect people from home fire deaths and voice its concern about the number of U.S. households without these early warning devices. While 96% of American homes have at least one smoke alarm, no smoke alarms were present or none operated in two out of five (41%) of the reported home fires between 2003-2006. Almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.
NFPA emphasizes the need to continue planning and practicing home fire escape plans and to make sure everyone in a home can be awakened by the sound of the smoke alarm. NFPA suggests practicing the escape plan during which the smoke alarm is activated so all family members know its sound.
Every home fire escape plan is different, and every family should know who will – and who won't – awaken at the sound of the smoke alarm. If someone doesn't wake up when the alarm sounds during a drill, the family should design an escape plan that assigns a grown-up who is easily awakened by the alarm to wake the sleepers, perhaps by yelling "FIRE," pounding on the wall or door, or blowing a whistle.
