Fire extinguishers are not accepted at our Household Hazardous Waste Depot. Some fire extinguishers can be refilled but many household fire extinguishers sold today are not refillable. If you cannot refill your common “ABC” compressed air, dry powder extinguisher, it should be de-pressurized and dismantled before disposal. Release the product into a trash receptacle then remove the valve by unscrewing from the canister. The metal canister, once de-pressurized and empty, may be recycled as scrap metal. The powder and valve can go in the regular trash.
PLEASE NOTE: Very old fire extinguishers (often brass, glass, or copper) may contain extremely hazardous substances. Please contact your local fire department for disposal options or bring them to a household hazardous waste collection.
