Abstract

Abstract:

In order to effectively reduce the occurrence of hazardous chemicals tank truck transportation accidents, identify key causes of the accidents and the transmission paths between factors. Based on the statistical analysis of 1041 hazardous chemicals tank truck transportation accidents from 2016 to 2020, 15 accident causation factors were extracted from four dimensions: human, machine, environment and management. Integrated DEMATEL method and ISM were used to analyze the correlation between each factor and the degree of influence on the accidents, and a multi-level hierarchical model was established. The results show that: wrong operation, tank and safety accessory faults are the direct key causes of accidents, while inadequate supervision and management, extreme weather, and inadequate education and training are the key causes of accidents. 23 and 16 accident transmission paths are developed, respectively, with inadequate supervision and management and extreme weather as the underlying factors. Among them, Inadequate supervision and management—inadequate education and training—wrong operation is the most dangerous transmission path, which should be controlled in accident prevention.

Key words: hazardous chemicals, tank truck transportation accidents, key causes, transmission paths, decision making trial and evaluation laboratory(DEMATEL), interpretative structural modeling (ISM)
