At present, there are hundreds of chemicals used in capacitor factories in electronic industry, which have different hazards to human body. The main invasion routes are skin infiltration and respiratory inhalation. Capacitor factories often use some toxic and harmful solvents as cleaning agents, such as washing water, whose main component is trichloroethylene. Trichloroethylene can damage liver function, and its symptoms are similar to hepatitis. Tianna water is also commonly used, generally containing benzene and toluene. Benzene is a highly toxic chemical with strong carcinogenicity. Patients with chronic benzene poisoning often suffer from aplastic anemia, including leukemia and toluene, and can also cause acute or chronic poisoning. In addition to solvents, all kinds of heavy metals are also very harmful to human body, and they are not easy to be discharged because of their accumulation in human body. In capacitor factories, this heavy metal mostly exists in the form of dust or smoke. If workers inhale for a long time, it will cause poisoning or excessive chemicals in the body.
Electronic industry is an industry with high incidence of occupational diseases. According to the statistics of relevant state departments, many factories fail to provide effective occupational safety protection and training according to law, and workers lack channels to understand occupational hazards in their working environment, which makes many people suffer unconsciously.
