Abstract

The smoke concentration at a distant location down a hallway as a function of different openings of the room of fire origin is considered. A series of tests is reported and the smoke sustaining (residence) time, the concentration peak and the concentration buildup rate are investigated as functions of the size of the opening. The smoke sustaining (residence) time, the most important factor concerning smoke toxicity, is described by a novel concept, wavelength, in this study. Furthermore, it is worth emphasizing that the smoke concentration at the sampling point exhibits a phenomenon of vibration in the case of the smallest opening during the test.
