Extended information:
Vinyl chloride, also known as vinyl chloride, is an important monomer used in polymer chemistry and can be produced from ethylene or acetylene. It is a colorless, easily liquefied gas with a boiling point of -13.9℃, a critical temperature of 142℃, and a critical pressure of 5.22MPa.
Vinyl chloride is a toxic substance, and liver cancer is related to long-term inhalation and exposure to vinyl chloride. It forms explosive mixture with air, the explosion limit is 4%～22% (volume), it is more likely to explode under pressure, it is necessary to pay attention to the tightness of the container and nitrogen sealing when storing and transporting, and a small amount of polymerization inhibitor should be added.
Storage management: stored in a cool, ventilated warehouse. Keep away from fire and heat source. The storage temperature should not exceed 30℃. Should be stored separately from the oxidizer, do not mix storage. Use explosion-proof lighting and ventilation facilities. Prohibit the use of mechanical equipment and tools that are easy to generate sparks. The storage area should be equipped with leakage emergency treatment equipment.
Transportation management: Railway transportation should be strictly in accordance with the Ministry of Railways "Rules for Transportation of Dangerous Goods" in the dangerous goods fitting table. Cylinders must be used for transportation with safety caps on the cylinders. Cylinders are generally placed flat, and should be the mouth of the bottle in the same direction, not cross; the height shall not exceed the vehicle's protective railings, and use triangular wooden pads stuck firmly to prevent rolling.
Transportation vehicles should be equipped with the appropriate variety and number of firefighting equipment. Vehicle exhaust for the shipment of the item must be equipped with fire stopping devices, prohibit the use of spark-prone mechanical equipment and tools for loading and unloading. It is strictly prohibited to mix and transport with oxidizers and edible chemicals. In summer, it should be transported in the morning and evening to prevent sunlight exposure. When stopping in the middle of the road, it should be far away from fire and heat source. Highway transportation should be in accordance with the prescribed route, prohibited in residential areas and densely populated areas to stay. Railroad transportation should be prohibited from slipping.
