Given the fact of where you are from, I doubt that you would have heard this. About 8 or 9 yrs ago, we had a really devistating flood in Baytown, home to the company Exxon. We are located right on the water. There is a plant right off the freeway that sells and transfers pure oxygen via large diameter piping run throughout the country. As the flood waters rose, so did a section of pipe that was carrying the oxygen. Once the pipe finally gave way, and the oxygen escaped, there was a massive explosion that rocked our world. That having been said, I have to disagree with you when you say that oxygen is not flammable.
