The Study Of Risk Assessment Way For Hazardous Materials Tanker Transportation In Railway

With the standardization of rail transport of dangerous goods, railroad tank cars play an increasingly important role in the transport of dangerous goods, how to improve tanker safety of railway transport has become increasingly important part of the problem. Railway transport tanker involved many links, difficult, for industry railway line carry handle tanker demanding. So industry railway lines for tank cars were evaluated, with the objective to achieve significance.Firstly, use the identification method to identify dangerous source of railroad tank cars in the first and second category hazards. Combined with accident cases and fault tree analysis method, identify hazard of the tank during transport and handling processes;Secondly, according to the basic principle of the Analytic Hierarchy Process, first create a special line railway tank car safety analysis evaluation level model suitable for our situation. Then invite a number of experts in the factors affecting the mutual model to make judgments, to establish analytic network model;Thirdly, during the process of determining the weights, considering the differences of different experts, using expert group decision-making to determine the different weight proportions in decision-making authority;Fourth, the actual situation of a special line of Sinopec, use the multi-level extension evaluation method for analysis. Get the final results of the evaluation..Studies have shown that the index system and model established in this paper applicable to analysis of rail transport of dangerous goods tanker in industry railway line. The results have some theoretical guidance and practical value of the production and transportation of dangerous goods railway safety management.
