在火灾中物质燃烧或热解产生的烟气,实际上是悬浮固体、液体粒子和气体的混合物。烟气具有相当的毒害窒息、遮蔽光线及高温对流作用。本文中,笔者从分析火灾烟气理化特性及其对受困人员与救援人员的危害性、火灾烟气对火灾蔓延发展的影响入手,结合建筑防火、灭火救援与疏散逃生等消防理论知识,归纳性地提出应在建筑布局形式与构造上设置防烟排烟设施、建筑装修装饰材料选材采用不燃难燃材料、逃生自救时掌握正确防范烟气侵害、消防队伍提高烟气应对能力等对策。
The fumes produced by the combustion or pyrolysis of a substance in a fire are actually mixtures of suspended solids, liquid particles and gases. Smoke has considerable poisoning suffocation, shade and high temperature convection. In this paper, the author analyzes the physical and chemical characteristics of fire flue gas and its hazards to rescue workers and rescue workers, the impact of fire flue gas on the development of fire start with fire prevention, fire fighting and rescue and escape evacuation fire and other theoretical knowledge, induction It is proposed that the smoke exhaust facilities should be set up in the layout and structure of buildings, the non-combustible material should be used in the decoration materials of building decoration, the correct protection against smoke gas should be mastered when escape and self-rescue, and the countermeasures should be taken to improve fire-fighting ability of fire-fighting teams.
