Nitrox mixing at home...

Now you've got me curiuous. I was told (and shown for that matter) that all the oxygen came off the same cooling column. I was given to understand that the only difference was the way in which the cylinders were handled (they all had to be clean inside but, as I recall, medical grade had a vacuum drawn on the cylinder prior to filling while industrial did not). Has this changed or is it different elsewhere?

 

[jrockosaurus]

Agreed....

to be fair, all materials by themselves are no more or less flammable than oxygen. the fuel and the O2 are both a necessary part of the reaction so saying O2's not flammable is like saying wood isn't flammable.

I often wonder how many people think 02 is flammable? I bet a poll with this question would be interesting...

Do a search.

Thread link: O₂ burns?.

Wood is a fuel, 02 is not. 02 is part of the fire triangle for sure, but if you throw a match in a room full of 02 guess what happens?

I think it depends on the place that fills the cylinders. Here, all O2 cylinders are filled by the same supply, so what you are saying is correct. The medical cylinders get vacuumed and analized, whereas the industrial just gets filled.

The match burns up really fast!

After it lands on the sofa?

Ha ha ha! Oh man talk about stirring the pot Rick!

You would be amazed at how many people would say the room full of 02 would explode....the 'match would burn fast' is exactly correct of course.

So what else can we learn on the internet today? hmmmm

So other than dude messing up his mix how DANGEROUS is his home brew idea?

Provided he plays by the "keeping things clean and oil free" and keeps his fill (booster) station clean ie dryers and filters, where is this HUGE danger??? Granted he is working with the high pressure etc, but in reality, provided he plays safe, he should be good to go.

I worked many years operating a Praxair (formally Linde Air Products) air seperation unit. All the oxygen (LOX) coming from the seperation column is the same 99.99% pure. The .01% remaining is mainly nitrogen. We didn't fill cylinders, that was done at another facility by pumping the liquid oxygen through a vaporizer to the cylinders.
