OK, I keep reading about how dangerous Oxygen is in pure form. So be it, pure Oxygen can be very dangerous if exposed to a source of ignition. As a welder, (certified in ’68, now just for fun) I can tell you the Scuba industry is by far way more cautious and concerned about handling O2 than anyone else. Go by any auto or muffler shop, metal fabricator or junk yard and see how clean the environment and tools used around the O2. A close friend of mine also fills the O2 systems on small general aviation aircraft from a portable bank of 8 AV200 (200CF). His shop and whips are clean and there is no smoking but other than that, no big deal.
I’m not going to officially recommend that a home user, not experienced handling O2 fill his tanks but with a little training and the appropriate equipment I would think partially filling a tank should be no problem. Frankly the danger of dealing with extremely high pressure poses significantly more risk.
