Better than rolling around, ya. Much if any value in the event of even a minor issue, no. A decapitated high pressure tank will easily bust through a properly constructed cinderblock wall & several pieces of plywood (Mythbusters). I know it would easily decapitate a person after going through windows either from momentum or gas propelled. Really my welding cylinders are the most frightening thing I haul even with inert gas. There is no way I'd haul them without making sure they can't roll or slide. Ratchet straps can hold round stuff if you get em tight & properly rigged.
