Do Not Put in Garbage
Because oxygen tanks can be pressurized, never dispose of them at the curb as garbage.
Although oxygen isn’t flammable, it can cause flammable substances to ignite. Store oxygen tanks in a cool, well-ventilated area away from people and anything flammable.
Empty the Tank
Before disposing, empty an unwanted oxygen tank by opening the valve and leaving it open, allowing all remaining oxygen to drain out.
Alternative Ways to Recycle
Recycle With Scrap Metal
Since oxygen tanks are made from steel or aluminum, some scrap metal recyclers accept them for recycling. Find out what to do with scrap metal.
Contact the Retailer or Manufacturer
If listed on your oxygen tank, contact the manufacturer or retailer and see if you can return the tank to them. Medical cylinders and scuba tanks are generally accepted by the manufacturer or retailer.
Ways to Reduce
Refill Your Oxygen Tank
Most oxygen tanks can be refilled and used again. For medical oxygen, contact a medical equipment supplier. For scuba oxygen, contact a dive shop.
