Smoke Detectors


Certain smoke detectors contain a radioactive sensing device, but the radioactivity is so low that it is considered harmless. It is OK to dispose in the trash.


Detector companies accept returned radioactive detectors for disposal as hazardous waste. Detectors have a limited life span, usually specified at ten years. Testing your detector with actual smoke is the only way to be sure it will work when needed. For more information call 800-323-9005 or 800-387-4219.

The vast majority of smoke detectors are made by First Alert Corporation. Look on the back for an address. Any manufactured in Aurora IL may be sent back to First Alert.
