- [ABSTRACT IN ENGLIGH] Different curtains were burned under air-supplied and air-tight conditions in a semi-full-scale room to evaluate the toxicity of their combustion gases. In the experiments under the air-supplied conditions, curtains mounted on the inside walls of a plywood 'box shape' were burned. Acrylic, modacrylic, nylon-6 or wool was used as material for curtains in each experiment. There was little difference in HCN evolution regardless of the material. When the weight of the curtains was 1-4% of the total combustibles, the toxicity due to HCN was, at the most, 20% of the total index. In the experiments under air-tight conditions, a non-flame retardant curtain of rayon, acrylic or polyester was burned on its one. When the content of curtains was equal to the average content in the room, CO and/or HCN concentration surpassed the lethal concentration for 5-10 minutes' exposure in the case of curtains of rayon and acrylic.
