does your list mean that suppliers use other colors for the military than for civil users?
If so, how do they avoid mistakes since I can imagine that military users are also used to civil bottles? Are military and civil bottles used mixed?
It's part of the contract with suppliers to have new pressure cylinders delivered either with the correct color coding, or unmarked and empty to be painted before use. When 'civilian' pressure cylinders are used, since there is no one standard for civilian gas cylinder markings, they're required to be prominently labeled if they have to be used before they can be repainted, and must be repainted before they can be refilled.
