Analysis and countermeasure research on management mechanism of hazardous chemicals based on active safety protection

It is of great significance to protect dangerous chemicals and to establish reasonable and effective management and rescue mechanism of dangerous chemicals for preventing and reducing accidents and disasters caused by dangerous chemicals. Taking Dalian City as an example, this paper studies the management mechanism and Countermeasures of dangerous chemicals based on active safety protection, uses Google earth to obtain the geographical position information of the units using and managing dangerous chemicals, introduces Dijkstra algorithm to design the calculation process of the best relief route, and constructs city's traffic network with fluid network theory. The traffic network diagram shows that the best rescue route v295-v75-v74-v37-v33-v15 can be calculated by simulating the rescue site and the place where the hazardous chemical accident happens, and the shortest rescue time is 360 seconds. The results of this study are of great significance and practical application value to improve the rescue efficiency of hazardous chemical accidents and reduce the damage of the accidents. ©. 2018, AIDIC Servizi S.r.l.
