Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.
At low oxygen concentrations, unconsciousness and death may occur in seconds without warning.
Later judgment becomes faulty and all sensations are depressed.
Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen .
This chemically inert element is colorless and odorless in both its liquid and gaseous forms. This gas is isolated through liquid air fractionation since the atmosphere contains only 0.94% argon.
Other uses incude non-reactive blanket in the manufacture of titanium and other reactive elements and as a protective atmosphere for growing silicon and germanium crystals.
Argon-39 has been used for a number of applications, primarily ice coring. Argon is also used in technical SCUBA diving to inflate the drysuit, due to its nonreactive, heat isolating effect.
This in turn requires the presence of a simple asphyxiant in a concentration of 33% in the mixture of air and gas.
