Analysis of Safety Warning for the Transportation of Flammable Solids by Railway

To further enhance the safety of railway transportation of hazardous goods, this paper takes the transportation of flammable solids by railway as an example to study the safety risk factors in the transportation process, providing insights for safety warning. Firstly, the entire transportation process is analyzed using the Hazard and Operability Analysis (HAZOP) method to identify safety risk factors in the transportation process, which serve as the basis for actual production operations. Secondly, combined with rough set theory, the obtained safety risk factors are screened to eliminate redundant factors that do not contribute significantly to safe transportation and extract core factors. Finally, based on the core factors, a safety warning index system for the transportation process of flammable solid substances is constructed, and the principles of safety warning operations are elaborated to provide reference for safety warning in the actual transportation production process.
