CHARACTERISTICS OF HAZARDOUS CHEMICAL ACCIDENTS

    1. Multiple: there can be hazardous chemicals accidents in any links of six process from production to waste.

    2. Susceptibility: their own characteristics of hazardous chemicals decide that there are hazardous chemicals accidents when they are heated, encounter wet, with water, friction, impact and other situation.

    3. Sudden: hazardous chemicals accidents occur suddenly, and the accident is not easy to detect precursor. Sometimes they occur in surprising.

    4. Complexity: cause of the accident are often complicated.

    5. Continuity: As the reason of the large and series equipments which are used for production and storage, the hazardous chemicals accidents often cause a chain reaction to the continuous accident.

    6. Diffusivity: once the hazardous chemicals occur the accident, it will quickly spread and spread widely.

    7. Harm with the special form.the harm including burns, poisoning, for people and pollution for environment.
