FEATURES OF THE APPLICATION OF THE METHODOLOGY FOR DETERMINING THE CALCULATED FIRE RISK VALUES DURING THE TRANSPORTATION OF FLAMMABLE GOODS BY RAIL AND ROAD

The work is devoted to the assessment of parameters affecting the magnitude of fire risk during the transportation of flammable goods by rail and road. The paper presents the results of estimating the frequency of fire-related accidents for truck vehicles and for freight railcars per kilometer. The conducted experiment on the evacuation of people from a passenger car is also described, the results of evacuation times for various conditions of evacuation of people are presented, the experimental results are compared with the calculated ones obtained by applying a computational model based on an individually flow model of human movement, as well as taking into account the provisions of existing fire safety techniques. The convergence of experimental and calculated values of evacuation times is shown. Based on the analysis of literary sources, recommendations are given for assessing fire risk on transport routes, including the calculation procedure, proposed conditional probabilities used to build event trees, formulas for estimating the area of fuel spread during leakage from a railway tank, and for assessing social fire risk.
