Abstract: In recent years, there have been frequent incidents of hazardous chemical transportation leaks, and the safety risks throughout the entire process of hazardous chemical transportation have become increasingly concerned. In order to effectively reduce the occurrence of hazardous chemical transportation accidents, a statistical analysis was conducted on the hazardous chemical transportation accidents that have occurred in China in recent years. The common liquefied petroleum gas (LPG) transportation accident was selected as the research object, and the Bow tie (BT) analysis method was used to analyze the hazard factors and accident consequences of LPG loading, unloading, and transportation. A Bow tie analysis model for the entire LPG transportation process was constructed, and preventive measures and accident consequence mitigation measures were proposed for key risk factors. The results indicate that the Bow tie analysis method, based on intuitive safety structure charts, can clearly express the causes, consequences, and corresponding prevention and control measures of accidents throughout the entire LPG transportation process, which is conducive to improving the level of LPG transportation safety management.
