摘要
针对独立建筑楼梯间出上人屋面的门是否装出口标志灯存在的争议情况,从疏散与逃生概念、标志灯在有组织的疏散中的作用、建筑内外各区域火灾风险等级划分及对应的“区域火险降级疏散”和在火险同级区域内“最短路径选择方向”的消防疏散原则等方面展开探讨分析。指出:独立建筑楼梯间出上人屋面的门不应安装出口标志灯,并应与通向可降级疏散上人屋面的门区别开来。
Inresponse e to the controversy over whether the door from the staircase of an independent building to the accessible roof should have an exit indicating luminaire,this paper conducts an exploratory analysis from the perspectives of evacuation and escape concepts,the role of indicating luminaire in organized evacuations,the classification of fire risk levels in various areas inside and outside buildings and the fire safety evacuation principles of"regional fire risk downgrading and evacuation"and"shortest path selection"within areas of the same fire risk level.It concludes that the door from the staircase of an independent building to the accessible roof should not have an exit indicating luminaire and should be distinguished from the door leadingtotheaccessible eroofwheredowngrading evacuation is possible.
