At concentrations of about 3.6 percent VCM in air, VCM can be an explosion hazard. organic chemicals (e.g., vinyl chloride monomer, ethylene dichloride, glycerine, chlorinated solvents, glycols). It is volatile, so the primary exposure is via inhalation as against food or water with occupational hazards being highest. Increased risk of hepatocellular carcinoma and liver cirrhosis in vinyl chloride workers: synergistic effect of occupational exposure with alcohol intake. VINYL CHLORIDE is peroxidizable. Annual production levels of vinyl chloride continue to increase, with 14.98 billion pounds produced in the United States in 1995.

On July 8 2010, over 900 pounds of vinyl chloride as well as other chemicals were released during another accident. Vinyl chloride is produced by chlorinating ethylene to produce 1,2-dichloroethane, which is then subjected to high pressures and temperatures. Vinyl chloride is also a product of anaerobic degradation of chlorination solvents such as would be expected to occur in groundwater and landfills. Epub 2018 Nov 25. 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. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Vinyl chloride finds its major application in the production of PVC. Help Me.
