Study On Safety Evacuation And Countermeasures Of Fire Personnel In Public Entertainment Places

With the improvement of people's living standards,more and more public entertainment places appear in the city.As some business operators failed to properly handle the economic benefits and the control costs of fire safety,fire accidents frequently occurred.Therefore,it is very important to study the safe ty evacuation and safety countermeasures of fire personnel in public entertainm ent places to reduce the probability of public casino fire and prevent the occur rence of casualties.Taking a public entertainment place in Zhaoqing City as the research objec t,the paper analyzes the distribution characteristics and flow characteristics of the crowd composition on the basis of on-the-spot investigation of the constru ction structure and the configuration of fire fighting equipment,and establishes a fire model for public entertainment places with the help of numerical softw are,and uses standardized hazard judgment standards.To carry out relevant stu dies,the main tasks are as follows:(1)Pyrosim software is used to simulate the fire dynamics and predict the concentration diffusion,temperature field distribution characteristics and laws o f flue gas and CO gas at the site.Seven monitoring points of human eye char acteristic height(1.5 meters)in different locations were selected to calculate the temperature changes after the fire.The results showed that the flue gas tempe rature was at a low level in the first 100 S seconds,and the flue gas concentra tion would not have a significant effect on the evacuation population for the ti me being..(2)Using Pathfinder modeling,the maximum speed and time of the single safe evacuation are calculated by selecting different escape exits,and the opti mal evacuation time is determined.According to the statistical data,the distrib ution of the personnel is determined,and the total evacuation time is calculate d.The necessary evacuation time(RSET)is 139 seconds,which is less than theavailable evacuation time(ASET)of 180 seconds.It is concluded that the fac ilities are in good condition and the channels are open.Fire personnel can safe ly evacuate the conclusion.(3)Put forward 1)set up and protect various types of fire fighting facilitie s in strict accordance with the requirements of the fire fighting technical specif ications;2)reduce fire load,effectively avoid fire,reduce fire loss,3)improve the emergency response mechanism;4)The safety evacuation and safety count ermeasures of fire personnel in public entertainment places such as fire fighting and evacuation work should be done well.The research results of the paper provide reference for the fire prevention design of public entertainment places and the evacuation of personnel in case of fire,and ensure that the personnel of entertainment places can be safely eva cuated in the event of fire,thus reducing the probability of casualties.
