NIH Global Vinyl Chloride Monomer (VCM) capacity is expected to experience considerable growth over the next five years from 49.38 mtpa in 2019 to 54.81 mtpa by 2024. A counter-intuitive finding from cohort studies of exposed workers is the lower mortality from liver cirrhosis with respect to the general population; this can be attributed to the healthy worker effect and to the selection of liver cancer as the cause of death in the presence of concomitant chronic liver disease. Mortality from liver angiosarcoma, hepatocellular carcinoma, and cirrhosis among vinyl chloride workers. Vinyl chloride OSHA Specifically Regulated Substances: OSHA 29 CFR 1910.1017 (vinyl chloride); The U.S. Department of Labor, Occupational Safety and Health Administration specifi-cally regulates manufacturing, handling and processing of vinyl resin. Epub 2018 Nov 25. It is volatile, so the primary exposure is via inhalation as against food or water with occupational hazards being highest. Portal hypertension, liver fibrosis, and angiosarcoma of the liver (ASL) have been reported among workers exposed to vinyl chloride monomer (VCM) since the 1970s.
