If the question is can someone go to the local Ox-shop, tell the

yeah. Just like you can use medications for off-label uses, but you
take
on extra risks by doing that.

The chief extra risk is that someone will claim that the welding O2 will
kill you for some nebulous reason. I guess the medial O2 atoms are
different from the welding O2 atoms.

I would say the extra risk is not quantifiable, at least within the
confines of a Usenet group.
Anyone interested, here are the FDA regs for med oxygen. The only
thing that really stood out initially is the requirement to double
purge, and some bookkeeping stuff.

My guess is that there is actually a miniscule amount of difference, but one
would have to use sophisticated equipment to discern the difference. And I
believe that the miniscule amount of "contaminants", or things other than O2
molecules would not be dangerous to anyone's health unless they were cyanide
or plutonium or something equally harmful. Not enough difference to make a
difference, basically.

But I would be curious to hear from a test lab. BTW, that was an awesome
document. What did it say?
