What are the hazards of benzene leakage?

1, causing poisoning. Because benzene is volatile, it spreads easily when it comes into contact with air. Inhalation or skin contact of large amounts of benzene by humans and animals can cause acute and chronic benzene poisoning. Long-term inhalation will invade people's nervous system, and acute poisoning will produce neurological spasm and even coma and death. A large number of leukemia patients have a history of exposure to benzene and its organic products.

2. Combustion and explosion. Benzene is a liquid with low flash point, lighter than water, insoluble in water, volatile and easy to flow. Benzene vapor is heavier than air, about 2.7 times that of air. Floating on the ground, water, sewers, ditches and other low-lying places after leakage. Without restrictions, just go with the flow. Its steam and air will form an explosive mixed gas, which will burn or explode when it meets a fire source, and it will also cause a large-scale flowing fire, which will directly threaten rescuers and vehicles.

3. pollute the environment. Benzene has fluidity. After the liquid leaks, it flows around, especially to low-lying areas, which will pollute the land and surrounding environment on a large scale and is not easy to be washed away. In particular, benzene flows into rivers, lakes, reservoirs and other waters, which will cause water pollution and seriously affect urban water supply.

The most important use of benzene in industry is as a chemical raw material. Benzene can be synthesized into a series of benzene derivatives. A series of compounds produced by substitution reaction, addition reaction and oxidation reaction of benzene can be used as raw materials for manufacturing plastics, rubber, fibers, dyes, detergents and pesticides. About 10% benzene is used as the basic raw material for manufacturing benzene intermediates.
