Hazardous Waste Special Instructions

Completely empty metal cartridges can go in the recycling. If there is any gas left in the cartridge (or you are not sure), it must be taken to the Hazardous Waste Facility for disposal, or returned to a supplier for exchange.

Never Dispose of Curbside

CO2 cartridges are hazardous because they are pressurized. Never dispose of them at the curb. Dispose of them as hazardous waste instead.

Keep Away From Heat

A CO2 cartridge is pressurized and may explode if heated, so keep it away from heat and out of direct sunlight in a well-ventilated area.
