Effect of Burning PVC
一项研究的效果of polyvinyl chloride (PVC) on the toxic gases generated in a cellulosic fire, tests indicate that the immediate risk in room fires is the production of carbon monoxide— not hydrogen chloride from the PVC. This is the conclusion of researchers at the Joint Fire Research Organization at Borehamwood, England, who conducted tests in small compartments.
When ventilation was slight, it was found that hydrogen chloride was produced at a low rate some 30 minutes or more after the evolution of carbon monoxide. With more ventilation, such as might be provided by an open door to a room, hydrogen chloride was evolved almost as quickly as carbon monoxide and in comparable amounts. The researchers concluded that the amount of hydrogen chloride produced by, for example, burning PVC wallpaper would not add much to the toxic danger already developed by the carbon monoxide generated by the burning cellulosic material (wood, paper and cloth) in a room.
