OK, so Welder's O2 might have traces of acetylene in it. Is acetylene poisonous? Are there any purity tests or would breathing a tin of it on dry land be the only way of testing it?
What else could there be (unexpectedly) in O2?
He - seems to be supplied as either pure or mixed with air. What nasties could we expect to find and would the air be "clean"?
I know a lot of guys have been down this route so what is the concensus? PM if you prefer...
