摘要
选取某生产车间进行应急疏散研究,使用PyroSim软件进行火灾模拟,得出各出口距离地面2m处温度、能见度及CO体积分数各参数随时间变化规律,计算可用安全疏散时间。利用Pathfinder软件建立人员疏散模型,对车间人员疏散进行研究,得出必需安全疏散时间。判断认为该车间人员不能及时疏散。发现部分出口人员疏散利用率较低,建议在不改变车间结构的情况下,指导车间人员进行分区疏散,使该车间人员能够安全疏散,同时加强人员疏散培训,改善应急预案。
A production workshop was selected for emergency evacuation research,and PyroSim software was used for fire simulation.The variation law of temperature,visibility and CO concentration at 2 m from the ground at each exit with time was obtained,and the available safe evacuation time was obtained.Using Pathfinder software to establish an occupant evacuation model,the workshop occupant evacuation was studied,and the required safe evacuation time was obtained.It was judged that the workshop occupant could not be evacuated in time.The evacuation utilization rate of some exit was found to be low.Suggestions were put forward,such as guiding the workshop occupants to evacuate without changing the structure of the workshop,so that the workshop occupant could be evacuated safely.Occupant evacuation training should be strengthened,and emergency plans should be improved.
