Cover sleeping areas and floors

The US Fire Administration advises smoke alarms inside each bedroom, outside separate sleeping areas and on each level of a dwelling, including basements. Building codes vary by country, so also check local fire-safety requirements. Interconnected alarms help warn people elsewhere in the home.

02 / 04

Test regularly and check dates

Test smoke alarms according to the manufacturer's directions, commonly about once a month. Replace batteries as specified and replace entire devices at the end of their rated service life; the USFA generally recommends a ten-year replacement interval from manufacture.

03 / 04

Smoke alarms do not detect every hazard

Carbon-monoxide detectors have a different role and may be needed where combustion equipment operates. Never disconnect a smoke alarm because cooking sets it off repeatedly; instead, check correct placement and suitable alarm type with qualified guidance.

04 / 04

Plan an escape route together

Agree on safe exits and an outdoor meeting point before an emergency. When an alarm sounds and a fire is suspected, leave promptly and call the local emergency service from a safe place. Avoid going back inside for valuables or pets if it would put people at risk.
