Abstract

The limitations of traditional hazard identification methods were clarified, and the STPA method of STMAP was applied to analyze the hazard event in which the CRES couldn't break the EMU, the safety problem was regarded as a control problem, the on-board earthquake emergency treatment device was taken as an example to analyze its unsafe control actions, the causes of the unsafe control actions, and it's hazardous factors were analyzed. A comparison was made between the traditional FTA method and the STPA method based on the STAMP model. The effectiveness of the STPA method in identifying hazardous factors was assessed. The results show that the effectiveness of the STPA method is greater than that of the FTA method, and that using the former can identify more than what using the latter can, and the difference includes but is not limited to design faults and poor communication. © 2019 China Safety Science Journal.
