Old smoke alarms

Smoke alarms should be replaced after 10 years to make sure they’re in good working order, says Owen Davis, spokesman for the National Fire Protection Association. There are two types of smoke alarms, ionization and photoelectric, which use different technology. Ionization smoke alarms contain a small amount of radioactive material, so safe disposal is important. Check to see if your state’s radiation control program offers collection of expired smoke alarms or mail the alarm back to the manufacturer, the EPA recommends.
