In order to reduce the risk of fire,reduce the evacuation time and improve the efficiency of emergency evacuation,a numerical simulation model of high-rise building fire was established by writer's team using Pyrosim and Fire Dynamics Simulator(FDS)to analyze the changes of smoke layer height,temperature,visibility and CO concentration with time in a hospital high-rise building in Shanxi Province.Then the Path finder evacuation simulation module is used to establish the emergency evacuation model,calculate the required safe evacuation time,and analyze the influence of smoke layer height,temperature,visibility and CO concentration on evacuation.Finally,the evacuation route is optimized by region division to reduce the safe evacuation time.
