Leave the canister intact
A household extinguisher still holds pressure until it is serviced or fully released by someone set up to do that work. Do not puncture the canister, do not cut the head off, and do not put it in a compactor. The gauge and the plastic handle do not tell a loader that the unit is safe. If you used it on a small fire and the gauge now reads empty, it can still be under some pressure or contain a dry-chemical residue that sites do not want loose in a truck. Keep the pin and hose on. Store it upright while you find an outlet.
Ask HHW or a service shop
Household hazardous waste collections often accept fire extinguishers from residents. Fire-equipment companies sometimes take old units when they service buildings. Call the HHW program or a local shop and ask what they want you to do with a home extinguisher. A transfer station may refuse it in the regular trash bay even when the rest of your load is welcome. If the label names a special agent, read that label to the person on the phone. Do not invent a discharge routine from a video. The program or the shop will tell you whether they want it fully charged, partially used, or already emptied by their staff.
Pack it so the handle cannot snag
Stand the extinguisher in a box or milk crate so it cannot roll under the seat. Do not bury it under bags. At the collection event, leave it in the vehicle until staff ask for it. Many HHW events unload chemicals for you. If a dump attendant turns it away, do not set it beside the oil tank and leave. Take it home and use the HHW appointment or the shop. Write down the date of the collection so you are not storing it longer than you need to.
Before you go
- Do not puncture the extinguisher or place it in trash or a compactor.
- Call the household hazardous waste program or a fire-equipment shop.
- Transport it upright, intact, and separate from loose debris.
- Hand it over the way that program tells you, or bring it back home if refused.

Questions people ask
What if the extinguisher is decades old?
Age is a reason to stop using it on a fire, not a reason to trash it. Tell the HHW program or the shop that the unit is old and let them direct you.
Can I recycle the empty metal can myself?
Only after a program or shop has handled the pressure and the chemical. Do not cut the canister open to get at the steel.
