Description

Vinyl chloride appears as a colorless gas with a sweet odor. Easily ignited. Shipped as a liquefied gas under own vapor pressure. Contact with the unconfined liquid may cause frostbite by evaporative cooling. Leaks may be liquid or vapor. Vapors are heavier than air. May asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. Suspected carcinogen. Used to make plastics, adhesives, and other chemicals.;GasVapor, Liquid; Liquid; OtherSolid;COLOURLESS COMPRESSED LIQUEFIED GAS WITH CHARACTERISTIC ODOUR.;WHITE POWDER OR PELLETS.;Colorless gas or liquid (below 7°F) with a pleasant odor at high concentrations.;Colorless gas or liquid (below 7°F) with a pleasant odor at high concentrations.

Stability

An unstable polyperoxide is apparently formed in vinyl chloride through oxidation by atmospheric oxygen in the presence of any of a variety of contaminants. Storage under these conditions for a long period increases the concentration of unstable polyperoxide to hazardous levels.;Long-term exposure to air may result in formation of peroxides that can initiate explosive polymerization of the chloride.;STABILIZERS ARE NECESSARY TO PREVENT DISCOLORATION FROM EXPOSURE TO LIGHT OR HEAT;AT ORDINARY TEMPERATURES IT MAY UNDERGO SLOW DEHALOGENATION WITH EVOLUTION OF HYDROGEN CHLORIDE
