I've read in a few posts that O2 cleaning is BS. Can someone elaborate. From training I understood the reason was to remove hydrocarbons. From what I understand, these are oil based and can basically catch fire or at least prolong a flash. I'm not a certified gas mixer, nor do I garage mix so I don't have an in-depth knowledge of the subject. From what I was told O2 is different than other gasses in that it gets HOT when going from a high pressure to low. Someone once told me that in a standard SCUBA tank, O2 rushing from 3000psi to ambient through the small opening of a tank valve can flash to 1500 degrees F almost instantaneously if the valve were opened all the way immediately. Don't know if this is correct or possible so if someone knows this is BS please tell me. I was "told" this so again I'm not sure. I did see some valves which were supposedly "melted" in this way. With this in mind, the use of O2 safe o-rings and grease will not promote or prolong a burn. I think O2 safe is basically that it will disintegrate instead of burning. Unless I forgot, was grossly misinformed or really confused, this is what I was taught in my Adv. NITROX class. Am I wrong? Why are people saying O2 cleaning is BS?
