You may not see fire, smell smoke or wake up in time to get out safely. Smoke alarms can help.
Smoke alarms are tools that can tell if there is smoke in the air.
They work even if you can't smell smoke. A smoke alarm makes a very loud beeping noise to warn you that a fire has started. When you hear the loud noise, follow your home escape plan and get out fast. Replace old batteries with brand new ones at least once a year. Keep smoke alarms clean from dust.
