Smoke and Carbon Monoxide Detectors
October 26, 2023
There are several different types of smoke and carbon monoxide detectors on the market. Ionization smoke detectors use a small amount of radioactive material (Americium-241) for detecting smoke particles. These devices need to be disposed in a safe manner.
Do not dismantle smoke detectors.
Do not remove the radioactive material.
Management options:
- Contact the manufacturer or distributor to ask about returning the smoke and/or carbon monoxide detector.
- Ask your local transfer station or household hazardous waste provider if they accept smoke and carbon monoxide detectors.
