How to Turn Off an Oxygen Tank With the Regulator

To turn off an oxygen tank, you need to stop the flow of oxygen. This is accomplished by using the cylinder valve, located on the regulator. To ensure the tank has been turned off, you also need to use the regulator's contents gauge, which tells you how much oxygen is currently flowing from the tank. A reading of "zero" can be attained by turning off the oxygen tank using the components of the tank's regulator.
