    The answer is resoundingly NO. Oxygen is NOT a fuel. Flames, fire and all related chemical reactions are a result of a FUEL being OXIDIZED, or being combined with oxygen. The application of oxygen to a burning fuel will cause the fire to burn much more vigorously, as well as hotter.

    Oxygen, by itself, WILL NOT BURN. If it did, our atmosphere (which is 20.9% oxygen) would have burned up a long time ago.

    Oxygen is mixed with a number of different fuel sources to get a faster, hotter burn. Acetylene, used in metal cutting torches, is mixed with oxygen to get a super hot flame that will quickly cut through metal.

    NASA uses oxygen to burn hydrogen fuel, not only to get a fast burn required in a rocket engine, but also because surrounding oxygen in the atmosphere becomes much more scarce as you leave the atmosphere for space.

    You've got to understand what fire is. Fire is the energy and material released when a substance quickly reacts with oxygen. Oxygen is everywhere, so you might wonder why things don't catch fire randomly. In order for something to burn there are two conditions. One, it must be touching oxygen, and two, it must be at the proper temperature. A match burns because the striking motion gives the heat, and the chemicals on the match react with oxygen. Oxygen CANNOT react with itself. That is, O2 cannot react with itself. We breath O2, so I assume that is what you mean. Oxygen is almost never just by itself. In conclusion, OXYGEN CANNOT BURN LIKE THAT. If there were, say, another gas like methane, then methane could react with oxygen and create a fire, but oxygen does not react with itself. The match will burn until the chemicals on it run out. Hope that helped.

    Oxygen is a reactive gas, not a flammable gas. Oxygen WILL ignite with oil, but it needs some kind of fuel source to burn. It is not flammable on it own.

    YES,IT SUPPORTS COMBUSTION

      You are an idiot...They use Hydrogen and Oxygen as the Oxidizing source of the fuel!

    NO, Oxygen is NOT flammable.

    Oxygen is required for other things to burn, but by itself it will not.

    Oxygen is flammable...

    NO! By itself with a spark and nothing else...it does NOT burn! It is an oxidizer and therefore adds to the combustion rate of whatever fuel is being utilized (for example:acetylene). Hope this helps!

    Oxygen is highly flamable. It will not ignite withought a spark or ignition source.

    Yes, it is the fuel source. NASA uses liquid O2 as a fuel source in rockets.
