Worker Exposure to Vinyl Chloride in Vinyl Chloride and Polyvinyl Chloride Production and Fabrication.
NIOSH 1977 Aug:196 pages
In assessment of worker exposure to vinyl-chloride (75014) (VC) and polyvinyl-chloride (9002862) (PVC) was reported. Toxicological data were presented, including acute and chronic animal and human studies, as well as reported worker exposures. Common methods of VC production, including the acetylene-hydrogen-chloride, oxyhydrochlorination, and ethylene-dichloride pyrolysis processes were described. A description of PVC polymerization processes, including suspension, emulsion, bulk and solution polymerization, were presented. A study to determine worker exposure to VC in monomer, polymerization and fabrication plants was described. Monomer and fabrication plant personnel had generally low levels of VC exposure, as compared to workers in polymerization plants. Workers in polymerization plants had the highest VC exposures. The author concludes that VC concentrations in polymerization plants are hazardous to the workers.
