The High-rise Building Fire Safety Evacuation Problems And Countermeasures

Many major malignant fire accident occurred in recent years, more than80%fireaccidents and fire safety evacuation has a direct relationship, due to the high building floorshigh, large size, many personnel, complex function, when a fire happens, many risk factorsaffecting the safety evacuation, safety evacuation and escape the preferred method ofhigh-rise building fire. High rise building fire in a burst and come, how to choose the best, thescientific evacuation route, choose the escape routes have scientific significance, whetherthrough calculation and practice, learning, exercise is able to adapt to the evacuation processunder different scenarios, is the main content of this article. Therefore, safety evacuation ofhigh-rise building fire, to further prevent and contain many malignant fire accident, to ensurethe safety of people’s lives and property, has a very important role.In this paper, by looking for high-rise fire a large number of cases, analysis of the causesof casualties, domestic and foreign research status of safety evacuation contrast, combinedwith the characteristics and safety evacuation in high-rise building fire risk factors, lack ofsafety evacuation design, from the safety evacuation management, safety evacuation,evacuation supporting the legal aspects of the current high-rise building in China safetyevacuation efforts.In order to solve the problem, using Pathfinder evacuation simulation software, in theimplementation of the required safety egress time should be less than the available safe egresstime evacuation standards under the premise, the high-rise building evacuation in differentscenes under the conditions of the simulation analysis, proposed in the design of evacuationsafety conditions, in different evacuation way conditions, building on the familiar degree isnot the same conditions, the simulation results were obtained, which were compared andanalyzed the results, so as to better guide the people to choose the right evacuation routes andstrategies. Finally, the evacuation simulation analysis in the safety of high-rise buildings,proposes four countermeasures to improve the safe evacuation in high-rise building efficiency,including strengthening the fire safety evacuation design, popularization of high-rise buildingfire escape skills, the preparation of fire emergency evacuation plan and strengtheningexercises, to promote the safety evacuation legislative work safety evacuation etc.
