Argon is an odorless, tasteless, and colorless gas. It makes up 0.94% of the Earth’s atmosphere and it is the third most abundant atmospheric gas. In welding, it is used to protect the molten pool, which is the place where the metals melt together, shielding the weld from unwanted contaminants and oxidation. It is also used in electric lamps and metals refining.

Argon is non-combustible and extremely inert, making it a silent killer in confined spaces. Large amounts of Argon will decrease the amount of available oxygen causing suffocation. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. Because it is shipped as a liquefied gas under its own vapor pressure, contact with the liquid can cause frostbite.
