Engineering control technology in polyvinyl chloride polymerization plants.
J Environ Pathol Toxicol 1979 May/Jun; 2(5):285-318
Technology for controlling worker exposure to vinyl chloride monomer (75014) (VCM) from polyvinyl chloride (PVC) (9002862) polymerization processes is reviewed. Suspension, dispersion, and bulk polymerization processes are described, and potential hazard and exposure sources are considered. Basic principles of control, such as process and equipment modification, isolation, local and general ventilation, work practices, personal protective equipment, workplace monitoring systems, and employee and employer education are discussed. Application of these principles to reduce VCM exposure to an 8 hour time weighted average exposure of 1 part per million is described. The author concludes that VCM exposure can be successfully controlled when these control principles function together as an integrated coordinated system, and that voluntary industrial implementation and sharing of effective preventive measures will promote the industry, labor, and government objective of preventing occupational illness; permit engineers and hygienists to benefit from the collective experiences of industry; and enable OSHA to operate less often in a crisis mode of regulation.
