Fire Hazard Analysis and Application in Trains
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 5
Abstract
Objective Fire accidents are major safety hazards in metro operation. To reduce fire hazards to an acceptable level and ensure the safe operation of trains, the research is specifically carried out. Method The safety analysis method outlined in EN 50126-2:2017 (Railway Applications – The Specification and Demonstration of Reliability, Availability, Maintainability, and Safety (RAMS) –Part 2: Systems Approach to Safety) is applied to analyze fire hazards in urban rail transit vehicle. Fire hazard lists for each system are established by identifying ignition sources and combustible materials. Using the HAZOP (hazard and operability analysis) method, components contributing to fire incidents are analyzed in detail to identify the causes of fires. Fire hazard identification is carried out in different scenarios during vehicle design, proposing mitigation measures, and tracking risk management measures until the risks are reduced to an acceptable level. Result & Conclusion The identified fire areas from the analysis of fire hazards in metro vehicles are applied to the scenario schemes of fire simulation analysis. The simulation results are used to further refine the fire hazard areas in metro vehicles, and the research results are applied to the design of fire alarm systems, enabling a more reasonable arrangement of fire alarm detection.
