| Hazardous chemical substance is one of the most reasons, which causes typical accidents. With the rapid development of national economy, petro-chemical industry has become mainstay industry than any more. Chemical substance has more relation with the living of people, but the safety problem caused by hazardous chemical substance has become more outstanding. At present, developing the safety management and consequence of accidents analysis system of hazard chemical substance is one of the main projects.In this paper, the author analyzed the character of hazard chemical substance and the disasters, expounded the technology and method of safety management and register management system, and explained the character of accidents and the main causes. This paper focuses on the model of disaster accidents in typical chemical process, such as explosion, fire and poisoned disaster. Kind, cause model and disaster mode of accidents caused by hazardous chemical substance have been put forward by analysis, sum-up and abstract of typical disaster accident cases in chemical and petro-chemical process. It also built the Math models of disaster accidents, and provided theory for realizing computer auxiliary management.Under the directed of system engineering and software engineering, this paper adopts DELPHI, SQL, database desktop based on DELPHI and MapObject based on Geography information ActiveX. In the part of management about hazardous chemical substance, we built character database, fire prevention and put out a fire database, major chemical disaster accidents cases database and law/regulations database. Using DELPHI, we designed the disaster accident consequence analysis system. It can simulate the process of explosion, fire and poisonous gas spread by using some relative math models.Finally, we can attain a good result by applying a real case. The result indicates that this system is available to aid chemical safety management and guard against disasters. |
