Carbon Monoxide / Smoke Detectors


The Illinois Environmental Protgection Agency recommends that an out-dated or non-functioning modern Ionization-type Smoke Detector or Carbon Monoxide Detector be disposed of in household trash. It can be secured in a plastic zip-type bag and placed in refuse bins with household garbage, after removing batteries for proper disposal.

  • These detectors are not on the list of electronics to be recycled.
  • They are not accepted at Illinois Household Hazardous Waste sites.

FEMA’s U.S. Fire Administration recommends replacing smoke detectors every 10 years. Dates are imprinted on side or cover.

If your detector has a radioactive material symbol on it, or if such a label has apparently been removed, contact the manufacturer for a mail-back program. They should send a secure box before you mail it.

Further discussion of other, or older smoke detectors can be found in this “Tech Talk” authored by the Federal Emergency Management Agency.
