Just thinking about a poison dart recipe I remember.
Minor quibbles:
Oxygen is non flammable. I supports other thing burning. Molecular oxygen (O2) is not very corrosive, atomic oxygen is. That's what makes ozone (O3) so bad.
Air is mostly nitrogen. You wouldn't want to breath pure oxygen for long.
