O2 Cylinder cleaning Hi all, I am wondering about cylinder cleaning, I am sure this subject must have come up dozens of times before but I am quite new to the forum and I couldn't find anything on a quick search, so please forgive me!! We have our small group of us CCR divers here in Nottingham in the UK and as we are now progressing to trimix we have found that we now need to keep 4/5 cylinders in O2 service every 12 months and this is mounting up to about 30 cylinders worth within our group. We therefore want to investigate to possibility of legitimately undertaking the O2 clean ourselves (not the cylinder test) but I cannot really find much info about how to undertake it or get appropriate training and certification for it. Can anyone shed any light on this process, training, where to obtain supplies, etc, etc. Many Thanks Luke |
