fire protection; smoke movement


Smoke and fire gases, inherent in all unwanted fires, are dangerous products of combustion that have critical influences on life safety, property protection, and fire suppression practices in buildings. In some fires, the volume of smoke is so great that it may fill an entire building and obscure visibility at the street level to such an extent that it is difficult to identify the fire involved building. In other incidents, the volume of smoke generated may be considerably less, although the danger to life is not necessarily diminished because of the presence of other airborne products of combustion. This chapter gives information on the techniques used to evaluate the physical characteristics of smoke movement through both short and tall buildings as a basis for designing smoke control systems. It also covers the approaches that can be used to test the effictiveness of designed smoke control systems in the absence of actual performance tests involving test fires.
