新型双层客车防火结构的设想

An Idee of the Flre Retardant Structure of the New Double-Deck Passenger Cars

新型双层客车,尤其是中长途双客的防火结构,参照国外经验,其防火阻燃等级应高于普通客车;应根据不同部位,选择防火、阻燃、或经防火处理的材料,尽量减少可燃材料的绝对用量;此外从结构设计上要有消除火源,防止火焰蔓延的措施;改进现有门、窗结构,使在有火情时便于疏散旅客;客室需设置灭火等装置。

With reference to foreign experiences,the fire retardant level and flame retardant level of the new doubledeck passenger cars, especially the middle and long distance passenger cars, should be higher than that of ordinary passenger cars, The fire retardant, flame retardant or fire retardantly treated materials should be selected according to different parts of the cars; The absolute amount of combustible materials should be reduced to as less as possible. There should also be measures to extinguish fire origins and prevent the spreading of flames. The present structures of doors and windows should be improved for passengers to exit safely in case of fire. Fire extinguishing devices should be provided in passenger compartments.
