What Are the Risks of Chlorine Exposure?

Vinyl chloride, also known as vinyl chloride, is an important monomer used in polymer chemical engineering. It can be made from ethylene or acetylene. It is a colorless, easily liquefied gas, with a boiling point of -13 ° C, a critical temperature of 151.5 ° C, and a critical pressure of 5.57MPa. The relative density is 2.2%. Vinyl chloride is a toxic substance. Prolonged inhalation and exposure to vinyl chloride may cause liver cancer. It forms an explosive mixture with air, with an explosion limit of 3.6% to 33% (volume). It is more likely to explode under pressure. When storing and transporting, the container must be sealed and nitrogen sealed. ^[1]

Used by Frenchman V. Lenio in 1835

1. Mainly used to make homopolymers and copolymers of polyvinyl chloride. It can also be copolymerized with vinyl acetate, butadiene, etc., and can also be used as an extractant for dyes and fragrances. Used as a comonomer for a variety of polymers, an important raw material for the plastics industry, and also as a refrigerant.

2. An important raw material for the plastics industry, mainly used for the production of polyvinyl chloride resin. Copolymerized with vinyl acetate, vinylidene chloride, butadiene, acrylonitrile, acrylates and other monomers to form copolymers, which can also be used as refrigerants. ^[3]

Skin contact: Remove contaminated clothing immediately and rinse skin thoroughly with soap and water. Seek medical attention.

Eye contact: Raise eyelids and rinse with running water or saline. Seek medical attention.

Inhalation: Quickly leave the scene to fresh air. Keep your airways open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.

Emergency response to leakage: Quickly evacuate personnel from the leaked contaminated area to the upper reaches, isolate them, and strictly restrict access. Cut off the fire. It is recommended that emergency handlers wear self-sufficiency

Closed operation, full ventilation. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear filter-type gas masks (half-masks), chemical safety protective glasses, antistatic work clothes, and chemical-resistant gloves. Away from fire and heat sources, smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent gas from leaking into the workplace air. Avoid contact with oxidants. During the transfer,
