An oxygen cylinder contains __ cubic feet of oxygen?

• A. 2,200
• B. 244
• C. Welding torch
• D. Striker

Answer: (B)

Gas cylinder capacity is expressed as standard cubic feet of gas, which measures how much gas is inside when the cylinder is full, at standard conditions. For welding work, an everyday full oxygen cylinder holds about 244 standard cubic feet of oxygen (at roughly 2,000 psi). That makes 244 cubic feet the correct amount. The value 2,200 cubic feet isn’t the standard capacity for a typical welding cylinder, and the other options are not quantities of gas.
