Oxygen (O2)
DESCRIPTION (Oxygen):


Oxygen is a colorless, odorless, tasteless gas. Typical uses include oxy-acetylene welding, the manufacture of steel and various chemicals, as a fuel component in the aerospace industry, for treatment of respiratory disorders. It is also used during high altitude flying and during diving operations.
