Smoke detectors have a life span of ten years. Many smoke detectors contain trace amounts of radiation and therefore it is recommended that you return them to their manufacturer for proper disposal. Manufacturer's addresses are usually listed on the product warranty, in the user's manual or on the original box. Return policies may differ among manufacturers, so calling the company prior to mailing is suggested.
Before disposing of smoke detectors, remove any batteries. Alkaline batteries may be deposited in the trash. Lithium batteries must be saved for a hazardous waste collection. Smoke detectors will not be accepted at hazardous waste collections.
The majority of smoke detectors sold in the United States are made by First Alert, 1-800-323-9005 or a Canadian company called American Sensors, 1-800-387-4219.
