In 2007, the International Agency for Research on Cancer established the association of VCM with hepatocellular carcinoma (HCC), though o … The following disease states have been observed in industrial workers exposed to vinyl chloride vapors: acroosteolysis, scleroderma, and Raynaud's phenomenon. Vinyl Chloride Monomer (Formula : C 2 H 3 Cl ) is produced by cracking EDC in PFR furnace. 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. 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.  |  Mortality from liver angiosarcoma, hepatocellular carcinoma, and cirrhosis among vinyl chloride workers. organic chemicals (e.g., vinyl chloride monomer, ethylene dichloride, glycerine, chlorinated solvents, glycols). Studies designed to overcome these intricacies confirmed an association between cumulative VCM exposure and the risk of liver cirrhosis. People subjected to dangerous chemicals are often entitled to take legal action. Epidemiology. Washington, D.C.: U.S. Chemical Safety Board. Chemical name :vinyl chloride Supplier's details : Vinyl Chloride Product use :Synthetic/Analytical chemistry. Huge storage tanks of Vinyl chloride monomer (VCM) are often regarded as major hazard installation because VCM is such a kind of flammable, explosive and toxic gas that leakage of liquid VCM would induce fire, explosion and toxic accidents. Vinyl chloride is produced by chlorinating ethylene to produce 1,2-dichloroethane, which is then subjected to high pressures and temperatures. Thereafter, recent reports from the United States cohort and a European sub-cohort of vinyl chloride workers provided compelling evidence of a strong association between cumulative VCM exposure and HCC risk. HHS Global vinyl chloride monomer market is expected to rise to an estimated value of USD 18.4 billion by 2026, registering a substantial CAGR in the … The incidents happened either in batch or semi-batch polymerization processes in connection with wrong catalyst introduction.
