Gas tanks can explode in DSNY compactor trucks and cause serious injury or damage. Follow specific guidelines below.
All gas tanks are accepted at DSNY SAFE disposal events.
If you are unsure about the type of fire extinguisher, check the label.
Dioxide or CO2 extinguishers are refillable and should be refilled after each use. Contact a local fire extinguisher retailer to refill or dispose.
Old (non-carbon dioxide or dry chemical) fire extinguishers may contain carbon tetrachloride, a known carcinogen. Contact a local fire extinguisher retailer to request that they dispose of your extinguisher.
Exchange empty propane tanks (or other pressurized cylinders) for a full tank at any local dealer. If not exchanging your tank, ask dealer to recycle, or bring to a scrap metal dealer.
Portable helium tanks can be recycled with other bulk metal items on your recycling collection day provided the valve has been removed.
