Analysis of Exit Density Change Based on Revolving Door Usage During Fire Emergency

Abstract

Revolving doors can impede rapid evacuation during fire emergencies due to their structural characteristics,

which pose a potential hazard. This study utilized the Pathfinder simulation software to analyze and compare

the Required Safe Egress Time (RSET) and occupant density based on revolving door passage speed and

utilization rates under different evacuation scenarios. When both revolving doors and swing doors were

operational, or when revolving doors were closed and only swing doors were used, areas with an occupant

density exceeding 3 persons per square meter were observed in the entrance area. However, when revolving

doors were deactivated and the width of swing doors was expanded, a reduction in RSET was observed, and

no areas with an occupant density exceeding 3 persons per square meter were identified. Therefore, buildings

equipped with revolving doors should acknowledge the risks associated with their use. They must ensure

sufficiently wide emergency exits or implement systems that allow revolving doors to open during

emergencies to facilitate efficient evacuation. Furthermore, it is crucial to establish additional regulations

governing the operation and safety standards of revolving doors during emergency scenarios.
