Five Minutes or Less for Health Weekly Tip: Check Alarm Batteries
Everyone should have smoke alarms and carbon monoxide detectors in their homes. Take a few minutes to ensure your alarms will sound in an emergency.
- Install a battery-operated carbon monoxide detector near bedrooms.
- Check or change the batteries in your carbon monoxide detectors at least twice a year.
- Install smoke alarms on every floor of your home.
- Test smoke alarms monthly to ensure they work properly. For smoke alarms that use regular alkaline batteries, replace the batteries at least once a year. For smoke alarms that use lithium (long-life) batteries, replace the entire alarm unit every 10 years or sooner if it chirps or stops working.
- Make a disaster plan. Know where to meet other family members in case of an emergency, such as a fire.
