Abstract
The toxic gases released from a fire can be classified as asphyxiants such as carbon monoxide, and irritants such as hydrochloric acid, etc. It is recognized that the combustion characteristic of interior upholstery is one of the important factors to determine the severity of indoor fires. In this study, several of the mostly used interior upholsteries including wallpaper, veneer board, curtain and floor cover, were selected to be evaluated by using the method of NES 713. The toxicity indices of the experimental samples, which indicate their toxic potentials in a fire were lowered in the order of Wallpaper (Flame Retardant) 8.5>Floor Cover(Hard) 4.8>polyurethane 4.3>Floor Cover(Soft) 3.5>PVC 2.8> Veneer Board 2.3> Floor Cover(flame retardant) 2.1>Wallpaper(Promulgation) 1.4>Curtain 0.9. It is concluded that, among all the tested upholsteries, wallpaper (flame retardant) would release the largest quantity of Toxic gases in a fire.
