Evidence of having been burned or exposed to fire, arc or torch burns.(f)
Damage to cylinder neck threads or inability to obtain a gas-tight seal by reasonable methods.(2)
If a compressed gas cylinder or tank shows any of the above conditions, or any other condition that could affect its safety, do not use it.
