if you look back at the posting it makes no difference. If I am wrong, so be it. It had nothing to do with my point... I was talking about welding near tanks that may contain dangerous gases. Oxygen does not have to be one of them.

This reference explains what I am talking about clearly:

A couple of key quotes:

"Oxygen's most important chemical property is that it supports combustion. That is, it helps other objects to burn. "

"Metal production accounts for the greatest percentage of oxygen use. For example, oxygen is used to burn off carbon and other impurities that are in iron to make steel. A small amount of these impurities may be desirable in steel, but too much makes it brittle and unusable. The carbon and other impurities are burned off in steel-making by blasting oxygen through molten iron.

As i posted, I participated in a project to build an oxygen storage system for a steel-making facility by taking advantage of shut-down windows to perform the necessary tie-ins. Other than those few weeks, the steel plant kept on operating.
