Medical oxygen

Dunno, but if I were on medical oxygen for, say, COPD, I would not wear that jacket while on the gas. I don't like the odds.

 

You survival monkey up the medical oxygen tree are out on a limb with this use of industrial oxygen.

Might consider with your monkey jabber the uses of an oxygen concentrator, one of which is as a source for your sleep apnea machine, the CPAC. Also recommended for heart and lungs, maybe just to poot into a living room.

 

It all comes from the same liquid oxygen tanker.

 

When liquid oxygen is contaminated it gives off a sulphur smell.

 

I know this is an old thread but it got drug up.
Sea, I would love to have been on some of your jobs. I've welded all over this blue marble, but have never been under the water doing it. Salvage has gotta be a rush at times. I have read your posts on this board and have envied you those experiences. I truly hope that some day Sass and I can hook up with you on the coast somewheres and trade stories over supper or drinks.

 

At what level does this occur?

 

When you can smell it the slightest bit.
Depending on what that smell is it could be in the parts per billion range.

 

Guess I've been lucky all these years then.

 

As a general rule, medical oxygen is compressed in oilless compressors. In the bad old days those were of the diaphragm type. Industrial oxy gets the filter treatment, for sure you do NOT want oil and oxy in the same pipes or hoses. To my knowledge, there isn't a standard for oil contamination in industrial gas, but I've been wrong before.

 

We always use a sniffer, the ones we got are pretty good and I've never gotten a bad batch of liquid O2 from my supplier in 40 years.

 

In the air force the sniffer is an enlisted person...

 

Oddly, the same applies to check for nerve gas....

 

We used Ensigns. Most of the dixie cups were trained in valuable skills.
