Empty propane or gas canisters under 2-pounds can go in your garbage.
Larger, barbeque-sized propane tanks (up to 5-gallons) must go to a household hazardous waste facility. This includes tanks that are empty or that contain any amount of propane.
For tanks larger than 5-gallons, call the Household Hazards line: (206) 296-4692.
