Analysis of Evacuation Safety in nursing hospital according to Korean Standards

Abstract

This study examines the impact of incrementally increasing evacuation routes on evacuation safety in multistory nursing hospital under Korean standards. Using the Pathfinder evacuation simulation software, a precise model was developed for a nursing hospital. Four distinct scenarios were simulated: a baseline scenario relying solely on internal stairs (Scenario 1), followed by scenarios incorporating external ramps at both ends of the corridor on the fifth floor (Scenario 2), on both the fifth and fourth floors (Scenario 3), and finally on the fifth, fourth, and third floors (Scenario 4).Simulation results demonstrated that each additional set of ramps significantly reduced the total evacuation time. Compared to the baseline evacuation time of 293.8 seconds (Scenario 1), the times for Scenarios 2, 3, and 4 were reduced to 262 seconds, 224.8 seconds, and 181.3 seconds, respectively. The results confirm that the initial addition of ramps eliminates the top-floor bottleneck, while subsequent additions create a networked evacuation system that allows for earlier egress, thereby more effectively relieving congestion in the internal stairs.
