East Palestine, Ohio, train derailment
On February 3, 2023, at 8:55 p.m. EST (UTC−5), a Norfolk Southern freight train derailed in East Palestine, Ohio, United States. The train was carrying hazardous materials when 38 cars derailed. Several railcars burned for more than two days and emergency crews also conducted controlled burns of several railcars, which released hydrogen chloride and phosgene into the air. Residents within a 1-mile (1.6-kilometer) radius were evacuated. Agencies from Ohio, Pennsylvania, West Virginia, and Virginia assisted in the emergency response.
Vinyl chloride
Vinyl chloride is an organochloride with the formula H2C=CHCl. It is also called vinyl chloride monomer (VCM) or chloroethene. It is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC). Vinyl chloride is a colourless flammable gas that has a sweet odor and is carcinogenic. Vinyl chloride monomer is among the top twenty largest petrochemicals in world production. The United States remains the largest vinyl chloride manufacturing region because of its low-production-cost position in chlorine and ethylene raw materials. China is also a large manufacturer and one of the largest consumers of vinyl chloride. It can be formed in the environment when soil organisms break down chlorinated solvents. Vinyl chloride that is released by industries or formed by the breakdown of other chlorinated chemicals can enter the air and drinking water supplies. Vinyl chloride is a common contaminant found near landfills. Before the 1970s, vinyl chloride was used as an aerosol propellant and refrigerant.
