Pure oxygen is flammable at all. When you look at the fire triangle you see that fire needs 3 things to happen, it needs oxygen, fuel and heat. If you lit a match in a room of pure o2 the match would turn into a raging fire, not because the oxygen is flammable, but because the fire has so much oxygen to grow with.
