Utilization of evacuation model for airports using risk based fire safety scenario

This report focuses the use of egress models to study the airport evacuation with special focus on security doors in case of total evacuation in airport terminal buildings. Case studies are made in arrival hall and departure hall of the airport terminal based on the scenarios identified in a preliminary risk analysis carried out in the terminal. Evacuation strategies are employed in the two different cases to study the evacuation based on the one way flow and counter-flow through security doors. This report presents the generalized method of designing an airport terminal based on the design peak hour passengers and the risk based fire safety method to identify the high fire risk locations with respect to the occupant evacuation safety. The evacuation strategies have been modeled in two simulation software tools (Pathfinder and LegionEvac) to compare the total evacuation time. The comparison between the models is discussed based on the total evacuation time. Based on the evacuation time, further evacuation strategies are simulated to study the flow pattern and evacuation problems with respect to airport environment. In the result section, critical factors which affect the airport evacuation and suggestion for optimization is discussed
