: OK, I've noticed alot of people posting that they want to know something about bulk tanks. OK CO2 bulk tanks are usually orange in color, are rated to pressures of 2400 psi and are rated to hold cryogenic liquid. Nitro tanks are blue painted, rated for anywhere from 6000-10000 psi (most are commonly 6000 though). Compressed air tanks are two toned and are usually blue and green, though i've seen yellow and green. They must have the green striping to indicate that it is an oxidizer. They are rated to 6000 psi and are stamped with the Oxidizer hazmat sticker. This is not entirely correct. First, there is no set color for any storage cylinder holding any particular gas or liquid at any pressure. Even the standard green for oxygen cylinders used in medical applications is not required by any regulating body, including the Compressed Gas Association (CGA). Our company has 4500 psi compressed air cylinders manufactured by Norris Cylinder Company and when we were getting our initial order, we were given a book of colors that we could paint the cylinders. So although there are common colors (breathing air - yellow, oxygen - green, nitrogen - blue, etc.), there is no set standard on colors, only valves. And no, they are not required to have any 'oxydizer' stickers on them.
