A CASE STUDY OF FIRE RISK ANALYSIS FOR GUIDE WAY TRANSIT PASSENGER COACH

초록

This is a case study of fire risk analysis for guide way transit passenger coach. 160 cases of fire accident scenarios were considered with event tree methodology. 4 liters of gasoline and cable fire at the electric cabinet and the modified ignition model of EN 45545 were selected for the fire sources. ASET(available safe egress time) and RSET(required safe egress time) methodology was used for calculating the dead. The fire was considered to be occurred at 3 different locations in the car. The train had 3 cases of driving scenarios. Fire simulations with FDS and Egress simulations with Simulux were adopted for calculating the fatalities. The risk result was plotted in F-N curve chart for the risk acceptance decision.
