Abstract

During a fire, flames can quickly spread throughout the room because the wallpaper covers the entire surface. Smoke generated from fire is a significant obstacle to evacuation. Therefore, it is essential to study the smoke characteristics of the wallpaper to ensure evacuation safety. This study used the ISO 5659-2 combustion chamber method to measure the smoke density over time with and without flame conditions using a 25 kW/m<sup>2</sup> radiation heat flux. The extinction coefficient represents the visibility in the smoke, and VOF4 shows the initial combustion smoke density characteristics. These two factors were derived from experiment results. Paper, cork, and cotton wallpapers were used as representative wallpapers. The results show that the maximum smoke density of all wallpapers was higher in the non-flame condition than in the flame condition. Under the flame condition, the maximum smoke density was measured in the order of cork, cotton, and paper. In the non-flame condition, the order was cotton, cork, and paper with the maximum smoke density. The extinction coefficient of wallpapers, except paper, exceeded 1.0 m<sup>-1</sup> in the flame condition, indicating that the smoke density provides visibility of 1-2 m under fire.
