Gas (CO2) Cylinders

CO2 gas cylinders are used for recreational activities such as Paintball games.  Because they are pressurized, they must be handled carefully whether they are being refilled or discarded.  Even when being refilled, they must periodically undergo special testing to make sure they do not pose an explosion hazard. First Strike Paintball Games will accept empty cylinders.

Helium-tankHelium Tanks

Once a helium tank has been properly emptied it may be taken to a scrap metal dealer.

How to properly empty a helium tank:

  • Take the tank to a well ventilated area, preferably outside. Open the valve handle. Press and hold down the nozzle until the releasing helium sound stops.
  • Remove the nozzle from the valve stem using a wrench.
  • Locate the rupture disk, which is a small plastic circle usually located on the shoulder of the tank. Using a flat head screwdriver and hammer, carefully pierce and remove the rupture disk. The edges around the rupture disk can be sharp so be careful.
  • Draw a circle around the open rupture disk with a permanent marker, then write “empty” on the tank, near the opening.
