- Abstract
- This is a check of smoke leakage from an entrance with a class A fire door in a highrise apartment, using a full-scale model. A model fire source was used which was designed to smolder 1 hour and then to flame. Doors opening in and out, with and without air tight material were used. A total of 13 types of experimental conditions were tested, the major variables being whether the door is open or closed, and pressure difference between the fire room and the corridor. The concentrations of smoke, gas, and smoke particles, and also pressures, temperature, and the weight of the fire source were measured. No difference in smoke leakage performance between doors opening in and out was obtained. Smoke and combustion gas in the corridor were hardly detected when the entrance door was closed. This clearly indicates that the central corridor is safe enough as an evacuation route when the door is closed.
