You're stuck on old paranoia based on information that is decades out of

and all are better than 99.99% pure O2.

I know how a medical tank was handled. I don't know anything abut a welding
tank. The oxygen may be pure going in, but I don't know what was in the
tank beforehand.

The gas suppliers are not about to fill 2,000 PSI+ of pure O2 on top of
some amount of unknown gas in the welding tank, that would be dangerous
for them.


I'm not stuck on decades information, my son owns a medical supply company
that supplies oxygen. I worked part time for him filling tanks and
delivering LOX. We followed the regulations on medical oxygen. You are
free to breath whatever you like though.

You follow your insurance / liability regulations, which do not in any
way relate to the actual safety of using the "welding" O2 vs. "medical"
O2, and have not been updated in decades.

They aren't doing anything different, those are the *standards*,
not the actual product spec. The reality is that both grades are
filled from the same cryo tanks and both exceed the 99.99% welding
grade standard.

So how is it known that these gasses meet this 99.99% spec?

Are they tested?

The source cryo tanks certainly are.


Or are they compressed with equipment that is known to NOT inject
contaminents during pressurization?

The same equipment is used to fill all "grades" of cylinders.


Much of what is speculated here is not with the "purity" of the source
gas, or the compentency of the compression equipment to maintain that
purity as a tank is being pressurized, but with what *might* happen with
these tanks when in the hands of end-users as they reach their empty
state prior to being returned to be reused.

Seems that some people here are hung up on that point, and we are all
speculating as to just what the gas retailer does behind the scenes with
these returned tanks prior to refilling them.

The gas suppliers are not about to fill 2,000 PSI+ of pure O2 on top of
some amount of mystery gas in the "welding" cylinder, especially since
those "welding" cylinders are typically used in conjunction with a fuel
gas. Putting pure O2 on top of some inadvertently transfilled Acetylene,
propylene, propane, etc. would not be a healthy thing for the workers at
the gas plant.

While that sounds logical, just saying it is not going to satisfy others
unless more concrete proof is posted to show that the average compressed
gas retailer or supplier performs the same processes and proceedures on
all types of returned cylinders (evacuation, internal cleaning, etc)
prior to refilling.

But I still submit that many of their arguments as to just how these
tanks can become contaminated in the first place is implausible.

Ummm..... no, it's not. Read the other responses in this

Yes, it's the same. Anything to the contrary is "urban

same stuff. All the O2 grades, including the five nines
analytical grade are filled from the same cryo tanks, and
only the analytical grade gets any extra testing to ensure
the 99.999% spec. The reality is that the welding O2 purity
standard (99.99%) is higher than the medical O2 purity
standard (99.95%), and that the actual product from the gas

Amazing: All those posts, guesses and "sound good" types mostly, for a

pathetic. This is precsely why groups like this have such low crediblity and

If it does not have that piece of paper, it is not medical oxygen. By

but you won't get it from me. Nor will your insurance company pay for it if

I know what is in medical oxygen and can trace the source. Until you can do
the same with welding oxygen, it is now allowed for patient use, now matter
how much you say it is the same. FWIW, the actual cost of oxygen has
little bearing on the cost of supplying it to a patient at home. It has no
bearing on how much a supplier is paid by Medicare or insurance,as that is a
fixed amount. They give the supplier $XX per month to cover the oxygen and
all associated supplies and costs. Some patient se 2X or 3X of others, butt
he amount paid is the same. If we could supply welding O2, it would be more
profitable, not less.

Actually all that is needed is to know that the FDA and other
agencies require certain additional tests to be performed and paperwork
filled out before something can be called medical oxygen. Under these
laws you cannot knowingly sell non-medical Oxygen for medical purposes
and the insurance company sure as heck won't pay for it.
If the question is can someone go to the local Ox-shop, tell the

The chief extra risk is that someone will claim that the welding O2 will

I've never stated either why what I think is done to returned welding
tanks prior to getting refilled.

The worst case situation is to assume that no special treatment is done
to them. They are simply connected to a compressor and they are
re-charged with O2, and probably using the same equipment, the same
valves and lines and the same source of O2 that are used to fill all O2
tanks that are sold or rented at that site, which could be for welding,
medical, or aviation use.

I said I did not know but you are trying to twist that. .

I said several times that you are proceeding from a point of view that
the handling and processing of returned welding tanks IS different from
that of medical tanks.

Let me ask you this:

If, hypothetically speaking, a compressed-gas supplier handled and
processed ALL returned O2 cylinders the same way (both welding and
medical cylinders) - which is to say that they are always cleaned,
evaculated, etc, according to medical-grade specifications, then what
would be your argument that an end-user shouldn't purchase a tank of
"welding grade" O2 for their own medical or veterinary purposes from
that supplier?

If it does not have that piece of paper, it is not medical oxygen.

I agree that selling a tank of welding O2 to someone as a medical-grade
tank of O2 (and charging medical-grade prices) is wrong and probably
violates all sorts of laws and insurance policies.

But we are not talking specifically about that situation (product
fraud).

If I buy welding O2 specifically for medical purposes, I agree that I am
taking some sort of risk that I have no recourse or remedy for should
the tank contain some harmful impurity. But I'm not convinced that a
medical tank has a lower probability of containing a harmful impurity
compared to a welding tank. The difference is that when I pay more for
a medical tank, I am in effect buying an insurance policy that allows me
to seek financial compensation. Perhaps I see no value in that
additional cost if the odds of any tank (welding or medical) containing
a harmful impurity are extremely low.

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?

I don't think anyone is saying the O2 is any different, just the possibility

not welding grade so I'm not going to speculate on the probability. I do

That piece of paper makes a big difference in the end use. It is not

I read the piece of paper that came from the O2 supplier. He does the
analysis and certifies it, then we fill patient tanks from the bulk tanks.
That complies with regulations. If we did that with welding grade and
distributed it for patient use, we'd be subject to all sorts of fines and
liability.

You are not working with facts. You are working with pieces of paper.


I bought two tanks last year or two, and one was manufactured by a company
now out of business for twenty years. The tank had 800# pressure in it. It
was out of hydro.

I took it to one place, and they told me to unload it on to their dock, that
they were confiscating it, thank you very much. I said, not as long as it
was in back of my truck they weren't. I asked the man what they would do.
He said they would take the tank and give me nothing. He said they would
not trade it for another tank, or make one dollar worth of adjustment in the
price.

I went it to place two. The guy said, yeah, they still see them every once
in a while, and they are considered a find that is worth $150 that can be
had for free if they can get it from you. They told me to take it home, and
grind all the rust and grunge and letters off around the collar, and bring
it back, and for $12 for hydro and the price of the fill, they would swap it
for another.

I told him that I had used it for cutting, and that I did believe that it
was oxygen. He gave me an OXYGEN sticker he said to slap on the bottle. He
said he was only doing it because it had 800# pressure in it. He said if it
came into the loading dock without a sticker, and with no pressure, it would
be treated as an unknown quantity, and would have to be tested, purged, and
possibly the tank would have to be rolled.

I asked him why he would do this, and the other company wouldn't. He said,
"I can't answer that, you will have to." Well, for me, it is a decent
enough solution. I was not grinding off the letters on a company that was
currently in business and that I knew owned the bottle. When the lease goes
out on one bottle I currently have with that company, I am going to return
it with a letter to corporate explaining why I will not be doing ANY
business with them. I had done nearly $5,000 worth of business with them
the year of this incident.

I think those little stickers (pieces of paper with glue on one side) are
also available in MEDICAL OXYGEN and would not be hard to locate and
reliable cylinders.

Look! It's official. It has a piece of paper on it. It HAS to be MEDICAL
OXYGEN.

Unless one has the really spendy test equipment, you don't know what you
have. Oxygen to me would tend to be more likely to be pure, as mixing
contaminants would produce an explosive situation, and I really don't think
that most people would take the chance.

I'm still interested in seeing the answer to Ed's question on what test
equipment that guy uses to make sure they have medical oxygen. Maybe they
just look at that paper sticker for quality control.

Your trick did not work, to shift to another non-existent group, Home

Let the American help you out, homey boi.

Mansfield, Ohio

Need the GPS coordinates?

I'll note you used another nym back then.

If there is a difference between welding oxygen and medical Oxygen, can anyone prove to me the difference, if it's just a tag, that is not proof, Talk is not proof, Just answer the question if you know for sure....

I used to work for a propane company and we delivered the K oxygen
welding tanks to medical cust., they used a medical regulator and a
medical humidifier. Of course that was in the early 60's.

You think someone got answer, since the question was four years ago?

Perhaps, but probably not the accurate one. The reality is that the
purity standard for welding O2 is tighter than that for medical O2.
Ultimately, except for the "analytical grade" all of them come from the
exact same cryo tank of O2 at the filling station.

Hi,
I am not an expert on this matter. There are 4 types Oxygen,
aviation, welding, medical, research. As far as I know welding
Oxygen is purer than medical one, and stored pressure is higher.

Chairman -

It's clear that homeguy is raising points and bring up facts and logic
that you either won't or can't refute in a clear and rational way, and
it seems to upset you.

I suggest you chill out and relax and just take it all in as our
country, our economy and way of life disintigrates in front of our eyes.

Homelessguy and facts, logic? Good grief, that does not compute.

He's a clueless troll with a serious penis envy directed at the USA.
As nestork correctly pointed out, there are all kinds of real
attrocities going on in the world today. North Korea, Central African
Republic, Syria, Putin gobbling up the Ukraine. Yet all this dope
drones on about in one OT post after another is the USA?

A friend uses "welding oxygen" to fill his breathing tanks for high
altitude flying in his Harmon Rocket.

Hope he doesn't catch fire and explode.
My guess, he'll be fine.

Medical oxygen must be at leas 99%pure, no odor. It is also tagged with
the lot so it can be traced. Often, it is from the same tanks as welding
oxygen as ts long as they both meet the minimum requirements, that is OK
to do.

In real life, I'd use welding oxygen if I was in need of it to breathe,
but as a supplier to patients, I'd not give it to you unless it had the
right tag. It keeps the lawyers away.
