아파트 내장재 중 마감재로 사용되는 벽지, 목재합판 및 장판 등을 사용하여 LOI(Limit Oxygen Index)와 NES 713의 측정방법으로 연소가스 방출특성을 고찰한 결과 난연 벽지, 장판 등의 난연성은 우수하였으나, 난연 벽지의 경우 점화원이 지속적으로 제공이 되어지면 유독가스를 많이 배출하였다. 장판, 벽지 및 합판을 질량별로 연소특성을 고찰한 결과 단일 CO의 양은 벽지가 가장 많이 측정되었으나 CO/Mass loss는 장판이 가장 높게 나타났다. 따라서 장판의 경우 연소시 적은 양의 연소로도 많은 유독성 가스를 방출할 수 있음을 알 수 있었다. Several types of widely used interior upholsteries including wallpaper, veneer board and floor cover, were selected to be evaluated by using the method of NES 713 text. Test results indicates that a fire with retardant wallpaper release a large amount of toxic gases when constantly exposed to a fire source. When evaluated in terms of the masses of released gases, the release of Carbon monoxide appears the highest in case of wallpaper fire, while the ratio of CO/Mass loss appears the highest in case of floor cover fire. Therefore, it can be concluded that, a large amount of toxic gas will release from a floor cover fore with even a small quantity of fuel.

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.
