Liquid Oxygen

Oxygen is an industrial gas produced from the process of air separation. It comprises approximately 21% of the air we breathe. Oxygen is an active element which, although not being burnt supports combustion and reacts, directly or indirectly with all elements except the rare gases. Gaseous Oxygen is colorless, odorless and tasteless. At 14%-16% Oxygen in air, signs of O2 deficiencies begin to occur with an increase in the rate and depth of breathing. At 4% Oxygen even a little bit of breathing can cause unconsciousness.
