benefits of updating INTER-INDUSTRY STUDY OF VINYL CHLORIDE WORKERS Product Stewardship - Demonstrates to workers, community residents, customers, and other audiences our collective commitment to characterize cancer risks associated with employment in VCM/FVC processes. Scientific Knowledge - Refines the estimate of the number of cases of human angiosarcoma of the liver (ASL) associated with operating VCM/FVC plants in the pre-1972 era in North America. - Provides basis for refining human cancer risk assessments which are used by government agencies for permitting facilities, etc. - Contributes ASL cases to the international registry. - Helps to resolve unanswered questions about alleged links to cancers of the brain, lung, and hematopoeitic system as well as address noncancer causes of death such as emphysema. Litigation Defense - VCM/PVC manufacturers continue to face toxic tort litigation alleging that numerous other types (non-ASL) of cancer are related to VCM/PVC employment. This type of research is useful in defending such litigation. GGB 3/15/M BOR 011936 i BENEFITS OF UPDATING INTER-INDUSTRY STUDY OF VINYL CHLORIDE WORKERS (cont.) Chlorine Issue - VCM/FVC continue to be a part of the general debate on health and environmental impacts of chlorinated organics. This type of research serves a valuable role in helping to debate the issues on the basis of good science. # V GGB 3/15/94 BOR 011937
