Smoke alarms

Smoke alarms that are properly installed and maintained play a vital role in reducing fire deaths and injuries.

Smoke alarms save lives. If there is a fire in your home, smoke spreads fast and you need smoke alarms to give you time to get out. Having a working smoke alarm cuts the chances of dying in a reported fire in half. Almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.

Here's what you need to know!
  • A closed door may slow the spread of smoke, heat and fire. Install smoke alarms in every sleeping room and outside each separate sleeping area. Install alarms on every level of the home. Smoke alarms should be interconnected. When one sounds, they all sound.
  • Test your smoke alarms at least once a month.
  • When a smoke alarm sounds, get outside and stay outside.
  • Replace all smoke alarms in your home every 10 years
    More about staying safe with smoke alarms.

In this Dan Doofus video, NFPA is reminding you to make sure you have enough smoke alarms in your home, test them monthly and replace them every 10 years.

  • Three of every five home fire deaths resulted from fires in homes with no smoke alarms (38%) or no working smoke alarms (21%).
  • No smoke alarms were present in almost two out of every five (38%) home fire deaths.
