青藏铁路机车司机室和客车车厢增氧后属富氧空气环境。大量的国外资料说明随着氧气分压力或氧气浓度的增加 ,材料的燃烧特性有很大的变化 ,容易点燃且火焰蔓延速度加快。因此必须特别注意青藏铁路机车车辆的防火问题。
Qinghai-Tibet Railway locomotive cab and passenger compartment after oxygen is oxygen-enriched air environment. A large number of foreign data shows that with the oxygen partial pressure or oxygen concentration increases, the combustion characteristics of the material has greatly changed, easy to ignite and flame spread faster. Therefore, special attention must be paid to the fire prevention and control of rolling stock on the Qinghai-Tibet Railway.
