This study was conducted to estimate (1) the proportion of U.S.homes with installed smoke alarms and fire escape plans, and (2) the frequencyof testing home smoke alarms and of practicing the fire escape plans.Methods. The authors analyzed data on smoke alarms and fire escape plansfrom a national cross-sectional random-digit dialed telephone survey of 9,684households.Results. Ninety-five percent of surveyed households reported at least oneinstalled smoke alarm and 52% had a fire escape plan. The prevalence ofalarms varied by educational level, income, and the presence of a child in thehome. Only 15% tested their alarms once a month and only 16% of homeswith an escape plan reported practicing it every six months.Conclusion. While smoke alarm prevalence in U.S. homes is high, only half ofhomes have a fire escape plan. Additional emphasis is needed on testing ofinstalled smoke alarms and on preparedness for fire escape plans.
