The majority of fatal home fires happen at night, when people are asleep. Contrary to popular belief, the smell of smoke may not wake a sleeping person. The poisonous gases and smoke produced by a fire can numb the senses and put you into a deeper sleep.
Inexpensive household smoke detectors sound an alarm, alerting you to a fire. By giving you time to escape, smoke detectors cut your risk of dying in a home fire nearly in half. The National Fire Protection Association (NFPA) estimates more than 94 percent of North American homes have at least one smoke alarm. But consider this fact: There are more homes with smoke alarms that don’t work, than homes without any alarms. These poorly maintained units create a false sense of security for residents.
