Wow a lot of confusion back and forth here!

Pure oxygen is not flammable. To burn it you would necessarily be making it impure, for instance using a match and you add all types of carbon compounds, sulfur, often phosphorus (red) and/or sodium/potassium chlorate or chlorate, which all mixes with the heat from the fire and can cause a nasty fire. Just like with a lighter your combusting butane and probably some other compounds too. Any degree of impurities in the oxygen also make it much more vulnerable to combustion.

Now as far as the word "Flammable" goes, it should be used for such fire hazards. There are some companies and older tanks that still use the term "Inflammable" which sounds like it means the opposite of flammable. Unfortunately it was (and sometimes is) used to mean the same thing. (The reason is that the prefix is not "in-" which means 'not'; but rather "into-"...which is why inflammable is intended to mean "into the flames!" If you wish you make the distinction that a gas is not a fire hazard, the word "Nonflammable" is the recommendation.

So 100% O2 is nonflammable, while 'dirty' oxygen/air mixtures are very flammable. I hope this clears up matters a little bit.

Oxygen is not flammable.

Fire is heat and light produced by an exothermic (heat producing) chemical reaction. The most familiar reactions of this type involve elements or compounds present in flammable substances (e.g. wood, paper and hydrocarbons such as petrol and paraffin) combining with oxygen, releasing heat and light.

The oxygen is itself not flammable, but is an oxidising agent, that is, an element or compound which removes electrons from other elements or compounds. This is what happens when oxygen combines with other elements: it has 6 electrons in its outer electron shell, needs 2 more to provide itself with a complete, stable outermost electron shell and has a strong tendency to take electrons from other atoms to form compounds. However, oxygen is not the most powerful oxidising agent. Fluorine is a more powerful oxidiser, and will combine exothermically with many flammable materials at room temperature, causing combustion.

My recent fire extinguisher training at work had a diagram of a triangle representing the 3 components of fire..being fuel,Heat,and Oxygen.Removing any one of these would stop the fire process.Oxygen itself will Support fire,but is itself not flammable.

Yes,Oxygen is very flammable.I didn't know of course untill i start working at a assistant living facility.They had caution signs up on the residents doors that had Oxygen tanks in their room.

Oxygen combines with other compounds and elements to form new compounds. But it doesn't burn by itself, so it is not flammable. It accelerates chemical reactions.

Yes, oxygen is flammable. The old people smoking while connected to oxygen tanks cracks me up. Both in the irony and the fact that the oxygen is flammable.

Absolutely not. Oxygen is utilized in combustion reactions (Fire) to allow whatever is being burned to burn better, but alone it is not flammable at all.

No, it's inflammable. So smoke 'em if you gottem.

Oxygen is not flammable but a good supporter of combustion.

Oxygen supports burning but its not flamable
