Dynamic Risk Assessment of Rail Vehicle Fire Based on Accidents Chain

In order to enhance the design standards of rail vehicles and proactively mitigate the occurrence of rail vehicle fires, this study employs accidents chain theory and risk assessment technology to investigate the dynamic fire risk associated with rail vehicles. The approach involves the comprehensive identification of potential fire hazard sources and a detailed analysis of the fire processes occurring within rail vehicles. Subsequently, a fire accidents chain model specific to rail vehicles is meticulously established. Qualitative and quantitative evaluations are conducted to assess the dynamic risk of fire accidents in rail vehicles. Through the dynamic risk assessment model, interdependencies and correlations between various events related to rail vehicles can be systematically delineated. This allows for the classification of accident risks inherent within the accidents chain. The research findings demonstrate the effectiveness of the dynamic risk assessment methodology in evaluating the dynamic risk levels associated with fire incidents during the operation of rail vehicles. These assessments provide a solid foundation for the design of fire prevention measures in rail vehicles, ultimately contributing to the enhancement of fire prevention strategies throughout the operation of rail vehicles. Consequently, this research significantly bolsters the capacity for fire risk prevention and control within the rail vehicle industry.
