Each year, there are an estimated 405,000 fires in residential structures which cause nearly 3,600 fatalities, 18,600 injuries and $4.7 billion in property loss. Since 1970, when battery-powered smoke alarmswere first introduced, smoke alarms have become a familiar presence in American homes. By 2000, they were installed in nearly 94% of U.S. households. Studies show that the presence of an operable smoke alarm substantially reduces risk of death in resi­dential fires and property losses are significantly less. 6% of U.S. homes are not equipped with alarms, but 40% of the homes with fires had no installed alarm.
