The Research of Classification Method for Significant Risk of Hazardous Chemical Tanker which in Transit

Accounting to the present situation of China's road transport for dangerous chemicals, governments at all levels has no specific classification methods of major hazard source for hazardous chemicals tanker in transit. In this paper, we use fuzzy comprehensive evaluation method as the theoretical basis, combined with cases of accident and research materials using the fuzzy statistical method to construct the membership, and to get a reasonable classification according to the principle of maximum degree of membership. In selecting evaluation factors we take into account the cause of the accident during transport, process control and consequences of the accident, divide hazard chemical tankers in transit into four grades through applying the method to the practice, and the classification results accord with the actual situation.
