Well we both have sources. One says yes, another says no. I am indeed a PSI inspector. And I am speaking of my ability to certify a tank as safe. I am not claiming to perform nor will I perform oxygen cleaning service. While the cleaning procedure is relatively easy with the required solvents, the drying procedure calls for hot filtered air or nitrogen, which I do not heave easy access to. All I am doing is determining if the tank needs to be cleaned. We will have to settle that we disagree on how CGA G-4.1 does not apply to scuba equipment. As far as I am concerned "equipment and systems handling any gas in excess of 23.5% oxygen by volume shall be designed as if that equipment and system is handling oxygen" sounds a lot like a scuba tank that may come into contact with 100% O2 to me.
As any open minded scuba diver should, I am interested in seeing what other agencies have to say. I have looked into what I believe are IANTD requirements. The also mention the CGA standards by the way. As far as I could tell, they do not require but strongly suggest and annual oxygen cleaning. I believe though that IANTD requires a less rigorous 40% as their level of O2 contact. I found info on the use of simple Green as a cleaning agent, which is OK, but not on the drying method. I am not an IANTD Gas Blender but I am interested in what they have to say. Are you able to share any electronic info?
