How to pump medical oxygen	by krisguy	2002-12-27 07:44:16
People have always wondered what it takes to pump medical O2, so here is a list of what I do: 1. Inspect tanks for physical damage. 2. Look for a retest date on each tank that's 5 years older than today. 3. Check the drug label and re-label if necessary. (USA - O2 is a drug) 4. Steel tanks need to be hit with a hammer to check for internal corrosion. 5. Each tank has to have remaining contents smelled and vented. If a tank is completely dry, nitrogen must be pumped in and then smelled. 6. Tanks must be vacuumed to a pressure of 25 inches Hg at sea level. 7. Pump the tanks. (Procedures vary -- my machine is like a giant milker in reverse -- liquid oxygen vaporized then pumped into cylinders) Test for leaks. 8. Take one tank as a sample and doccument how it analyzes out (% of pure oxygen -- 99.00% minimum) 9. Cap, leak test again, and put a lot sticker on all tanks. 10. Release. This is a generic view, FDA requires a lot more and doccument everything.

N2 is odourless. Odours indicate contamination. (n/t)	by toxin	2002-12-27 10:49:20
