Vinyl Chloride Monomer (VCM) Emergency Shutdown SystemAbout Vinyl Chloride MonomerVinyl Chloride Monomer is a colorless gas with a slightly sweet aroma at standard temperature and pressure. It is an inhalation hazard and has been linked with the formation of angiosarcoma. In the presence of air, Vinyl Chloride Monomer is an explosion hazard as well. Upon standing, it can produce peroxides, which may then explode. It is reported that "large fires of this material are practically inextinguishable". Vinyl Chloride Monomer is used almost exclusively in the production of polyvinyl chloride (PVC). It is shipped in pressurized tank cars having angle plug or angle ball valves. Synonyms: monochloroethylene, ethylene monochloride, monochloroethene, VC, VCM, chloroethene, chloroethylene Accidental Release of Vinyl Chloride MonomerIn the event of an accidental spill or release of vinyl chloride monomer, it is recommended to shut off the gas supply if this can be done safely.
