Xenon appears as a colorless odorless gas. Noncombustible. Heavier than air. May asphyxiate by the displacement of air. Under prolonged exposure to fire or heat containers may rupture violently and rocket.

Xenon, refrigerated liquid (cryogenic liquid) appears as a colorless odorless nonflammable cold liquid. Boils at -150 °F. Contact with the liquid may cause frost bite. Can asphyxiate by displacing air in enclosed spaces. Exposure of the container to prolonged heat or fire may cause it to rupture violently and rocket. Used to make flash bulbs for photography.

Not Chemically Reactive

Not Chemically Reactive

These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions. These materials may be nontoxic. They can asphyxiate.

These substances undergo no chemical reactions under any known circumstances. They are nonflammable, noncombustible and nontoxic. They can asphyxiate. Contact of very cold liquefied gas with water may result in vigorous or violent boiling of the product and extremely rapid vaporization due to the large temperature differences involved. If the water is hot, there is the possibility that a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquid gas contacts water in a closed container [Handling Chemicals Safely 1980].

Radiopharmaceutical Activity [MoA]; Inhalation Diagnostic Agent [EPC]

Gases or volatile liquids that vary in the rate at which they induce anesthesia; potency; the degree of circulation, respiratory, or neuromuscular depression they produce; and analgesic effects. Inhalation anesthetics have advantages over intravenous agents in that the depth of anesthesia can be changed rapidly by altering the inhaled concentration. Because of their rapid elimination, any postoperative respiratory depression is of relatively short duration. (From AMA Drug Evaluations Annual, 1994, p173)
