Then why doesn't everyone smoke in the operating room? What's up with the no smoking around oxygen tanks? hmmm?
The only thing it does is make the flame burn hotter, also once the steel is to temp, you push the oxygen handle on the torch, and the oxygen stream blows the molten steel away. That is why on the bottles it doesn't say FLAMMABLE. It says OXIDIZER. Gee I actually use it in a flammable device. Ever work in a weld and fab shop. Didn't think so.
I'm quite sure the smoking room that the Nazis had closed did not have oxygen tanks in it.
