Abstract

In order to prevent safety accidents in railway dangerous goods transportation system, risk-accident evolution mechanism of it was analyzed and corresponding control methods were studied based on FRAM. A hierarchical risk-accident evolution network was established, and risk elements that influenced input and premise of FRAM were categorized into five aspects, personnel, equipment, goods, environment and management. Finally, odium cyanide leakage accident of a station in eastern China was analyzed for case study. The results show that three functional modules, including concealment of dangerous goods types, illegal packing and malpractice of inspectors, cause internal changes of respective modules as well as abnormal oscillations which are transmitted through non-linear and dynamic coupling effects and functional connections, further leading to non-linear coupled resonance among these functional modules. The connection between dangerous good transportation and unloading functional modules is broken and exceeds system risk-accident critical threshold, and macro-level structure sees a step mutation, resulting in an accident. © 2020 China Safety Science Journal.
