Store Carefully Although oxygen itself 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.

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.
