Abstract

This study analyzes the effects of personal lockers, drinking fountains, and all-in-one shutters (hereinafter referred to as "corridor walking obstacles") on evacuation safety to suggest the necessity of operating a more effective educational facility safety certification system. To achieve this purpose, the five-story high school building with the obstacles installed in the corridor has been chosen, and evacuation tests through the Pathfinder Simulation Program have been carried out. When the evacuation exit is designated in the current state, where the students are placed on the 2nd, 3rd, and 4th floors and the corridor walking obstacles are applied as a variable, the required safe egress time (RSET) is 322 seconds. This can lead to dangerous results in the event of a disaster by exceeding the available safe egress time (ASET) standard of 240 seconds by 82 seconds. When students are placed on the 1st, 2nd, and 3rd floors under the same conditions, the RSET is 214.5 seconds, 25.5 seconds lower than the ASET standard, indicating that it is effective in reducing the impact of walking obstacles on evacuation time. The safety management plan for walking obstacles in the corridors is discussed, considering the special characteristics of the school corridors. The results of this study can be used as the necessary data for optimizing evacuation routes in corridors and creating a safe, educational environment.
