Characteristics of traditional chemical industry

① The industry is complex, with many varieties and great technical differences. Complex production process means that a product may have multiple production process routes, which brings certain difficulties to safety production management.

② Production is dangerous. Most chemical production processes are characterized by high temperature, high pressure, flammability, explosion, poisoning and corrosion. For example, the synthesis of calcium carbide, sulfuric acid and chemical fertilizer is produced at high temperature; Liquid chlorine, hydrogen and carbon monoxide are flammable and explosive substances.

③ The stability of the equipment is difficult to master. Production equipment is prone to leakage, which not only pollutes the environment, but also causes fire and explosion accidents. Defects in design, material selection, manufacture and maintenance of any link such as equipment, instruments, pipelines and valves used in production will bring danger to production. ?
