Smoke Detectors

  • Lifespan: Detectors have a limited lifespan; it is suggested you replace them every 8-10 years.
  • Dispose: Certain smoke detectors contain a radioactive sensing device, but the radioactivity is so low that it is considered harmless. It is okay to dispose in the trash so long as the batteries are removed before disposal.
  • Return to Manufacturer: Many manufacturers accept returned radioactive detectors for disposal as hazardous waste. Click here for a list of manufacturers.
  • Other Disposal Resources: Curie Environmental Services, see link here for more information.
