Research on Fire Spread Characteristics of Escape Room Entertainment Venues with Spatial Complexity

: Aiming at the characteristics of large fire load, cramped space, and complex interior decoration of escape rooms, and their safety hazards of rapid fire spread and difficult evacuation after fire, the study was based on the Pyrosim software to investigate the fire spread, smoke flow, visibility changes and temperature changes after fire in the escape room, and to analyze the problems and deficiencies of the existing decoration methods in the case of fire, and to propose improvement measures for the existing decoration methods. The simulation results showed that the design of long and narrow corridors should be avoided in the escape room, and the partition walls of the escape room should be designed with through-roofs in the process of renovation, and the escape room should be equipped with two evacuation paths in order to shorten the escape time to the greatest extent possible. The study of the fire spread characteristics is of great significance to safeguarding the lives of entertainers, and it can also provide a reference for the evacuation of escape room entertainment venues.
