Hi Maki,

Thanks for this review: very handy for engineering dios.

For the right color codes one may look at https://en.wikipedia.org/wiki/Bottled_gas

For US military usage, look at MIL-STD-101B; the specifications for gas cylinders is section 5.2 starting on page 14, with Table III giving the specific colors by gas beginning on page 18.

Hi Sean,

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?

Thanks in advance for answering,

P.

You tend to get two types of Oxygen, the oxygen as marked for the likes of an oxy acetylene and for aircraft breathing oxygen which is purer.

Example

Military tend to be black with white heads for Oxy and grey with black for nitrogen, they also carry the bottle pressure markings etc

Example

Ohh and they dont like tyres filled with Oxygen as opposed to Nitrogen, they didn't last long on the landing run, saw it happen

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.
