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.
