There are quite a few who provide industrial and medical gases: Matheson, SPecialty Gas Products and Liquid Air Products are three that come to mind. Cylinders from Matheson and SGP differ in the color coding as described in the referenced article (not included because of it's size) quoting Airco's technical manual. As for Liquid Air, aside from the giant dewars used for liquified gases, I haven't seen their cylinders in some time and don't recall what colors they use. There would seem to be no way to be really sure about the contents of a cylinder without knowing who produced it and knowing the color scheme used. That's from a distance - up close, one can look for the DOT mandated labeling on the cylinder. JJD onymouse@netcom.UUCP
