A three-dimensional mathematical model for calculating 
the heat and mass transfer in a fire within a building has been proposed. 
The results of theoretical calculations were compared with the experimental 
data, the analytical solutions, and the integral mathematical model 
of the fire. Based on the numerical calculations performed by the 
model proposed the author determined certain features of the initial 
stage of a fire within a building, which made it possible to develop 
a system of early detection of a fire using pressure transducers.
