Can one breathe industrial oxygen

And if the fill plant doesn't vacuum out that potential contamination, particularly the most probably acetylene, before putting high pressure pure O2 on top of it, their fill plant will go BOOM! Any traces small enough to not be a safety problem at the fill plant are also too small to be a safety problem breathing the O2. If acetylene was toxic enough to harm you at a tiny fraction of a percent, welders would be dropping dead all over the place just from turning on the acetylene to light their torches.

The purity standard for welding O2 is higher than the purity standard for medical O2. Only the analytical grade has a higher purity standard and sees any additional testing.

Details, details...

No.

A very sick person.

Life is definitely not fair.

!! Great idea. Anybody tried this with live shrimp? I see a trial coming. FWIW, shrimp are extremely difficult to keep strong and kicking without a very large live well and lots of fresh salt water flow. Everything in the ocean loves to dine on shrimp.

Iggy,

If the patient is Medicare aged, his or he doctor can arrange O2 at home for as long as the patient needs it. It is covered by medicare and transparent to the patient.

If you want a medical O2 tank for experimental purposes, I have one or two home sized units for you here in Jersey.

I own a lot of crowbars, but I'm certain that I couldn't get enough of them into use to pry my wallet open for one of those pumps.

What'll that cost, I wonder?

Is that a military compressor?

I suspect probably $1k or so for the necessary parts.

No, it's a commercial one as used at fire departments and dive shops. Actually I believe it's rated to 6,000 PSI, though I don't really need it that high to fill 3,000 PSI cylinders.

Except on some days, crazy speckled trout seem to prefer some form of plastic. But if you're taking kids, or it's hot and you'd rather sit and relax while watching a cork, I much prefer shrimp to lures. The monday before Christmas, SWMBO caught a 23" speck on a sand eel jig. That's her facebook pic now.

You misunderstand. The FAA spec is {say} 94.5% dry. But I suspect that is "AT LEAST 95.5%" ergo welding gas at 97% passes.

That's not the only fun you can have with compressed gas. I recall that not once but twice, Koch Refining burned down the CO2 plant attached to their refinery. We never figured out how...

Well, almost.

A minor concern might be tank contamination.

Welding O2 bottles get reused in an uncontrolled environment. You might possibly end up with a welding bottle of oxygen that was used in a lab and had something terrible backflowed into it before the last filling....

And then happily blow up the engine of the fire truck that responds..

They vacuum out the cylinders before refilling. Putting high pressure pure O2 on top of an unknown gas is dangerous.

Yes, but you have to admit that a lot of people have gotten big bucks for small injuries. Or perceived injuries and transgressions and "emotional distress."

And a lot of walking wounded left the courtroom with empty pockets.

Knew I should have been more specific.

My mother explained that to me the first time I ever whined "it isn't fair". She said life wasn't fair and to get over it. I was maybe 5. She had a pretty good grasp on raising all of us.
