一、烟雾能见度和感觉刺激1、能见度对建筑物火灾,各类研究学者对其烟雾浓度与能见度之间的关系进行了调查研究。Jin 在1981年得出的结论是:对不熟悉环境的人,适当的能见度极限是可看见13m 距离(相应的可见浓度为0.06/m);对于熟悉避灾路线的人则为4m 距离(相应的可见浓度为0.2/m)。Rasbash 在1975年得出的结论是:能见度的极限值至少应为10m 距离(相应的可见浓度为为0.08/m)。
First, the smoke visibility and sensory stimulation 1, Visibility Fire on the building, all kinds of research scholars on the relationship between the smoke concentration and visibility were investigated. Jin concluded in 1981 that for people who are unfamiliar with the environment, the proper visibility limit is a visible 13m distance (corresponding to a visible concentration of 0.06 / m) and 4m for people familiar with the hazard avoidance route Visible concentration of 0.2 / m). Rasbash concluded in 1975 that the limit of visibility should be at least 10m (the corresponding visible concentration is 0.08 / m).
