How to Dispose of a Fire Extinguisher

To dispose of an old fire extinguisher that cannot be refilled or that you do not wish to refill:

• Release any pressure contained in the canister by shooting a small amount into an open area. 
• Let the canister sit for a few days, making sure the pressure has been released. 
• Once there is no longer any pressure, dispose in a trash bag in your regular garbage.

Fire Extinguishers with Content

• Determine how much content is inside the fire extinguisher by looking at the pressure gauge. The gauge will show you if the unit is overcharged, at the correct pressure or in need of a recharge. Unless the fire extinguisher gauge shows the unit is at the correct pressure, it will need to be refilled or recycled.
• Contact your community’s Department of Public Works to find out when the next Household Hazardous Waste Event is being held so you can dispose of any fire extinguishers that have contents remaining in the cylinder.
