CHANGE OF FIRE COURSE CONDITIONS AT ACTIVATION OF A DEVICE FOR SMOKE AND HEAT REMOVAL AND FIXED EXTINGUISHING DEVICE

Abstract

This report describes changed conditions of the course of fire at activation of selected
fire safety devices, which particularly include devices for smoke and heat removal and fixed
extinguishing devices. Particular attention is paid to the fire development stage. In principle,
changes are described in the form of simple equations and represented graphically. The study
elaborated with the use of the CFAST fire zone model demonstrates how the selected
characteristics describing the course of fire are influenced if the specified devices are activated.
