From the summary:'Experimental study on the visibility through fire smoke was carried out. The relation among the brightness of sign, visual distance, and the extinction coefficient of smoke at the instant of obscuration threshold was obtained by using the smoke chamber. The…

This paper describes the results of examining the influence of radiative heat transfer on turbulent natural convection above fires in an atmosphere of constant potential temperature, under both the 'opaque' and 'transparent' approximations. It turns out that on the basis of the…

An aerial ignition system using and incendiary device and a helicopter can be used to backburn a large area safely and completely. The system was used to backburn 4,800 acres and helped bring under control a large fire in February 1986. The system and the conditions under which…

[Excerpted from text] Most experienced firefighters have encountered fire whirlwinds. These whirls, or "fire devils" as they are sometimes called, range in size from small twisters a foot or two in diameter up to violent whirls equal to small tornadoes in size and intensity.…
