以某大型聚丙烯仓库为例,针对该仓库面积超过规范规定的问题,设计了防火分隔并对这种消防设计进行判断论证;同时采用FDS和STEPS对仓库现阶段情况进行火灾烟气和人员疏散的模拟.研究表明,在自然排烟条件下,火灾烟气对人员没有构成威胁,427.5 s内即完成了仓库全部人员的疏散,且安全余量较多.在现有消防设施正常工作的条件下,能满足人员安全疏散.该企业仓库能够达到预期的防火设计火灾安全性能目标.
Taking a large polypropylene warehouse as an example, aiming at the problem that the area of the warehouse exceeds the standard, fire separation is designed and the fire design is verified. At the same time, the fire smoke and evacuation of the warehouse are evacuated by FDS and STEPS The research shows that in the natural smoke exhaust conditions, the fire smoke does not pose a threat to the personnel, and all personnel in the warehouse have been evacuated in 427.5 s, and the safety margin is more .In the existing conditions for the normal operation of the firefighting facilities , To meet the safety evacuation of personnel.The enterprise warehouse to achieve the desired fire safety design fire safety objectives.
