摘要：

Statement of the problem. The existing methods used for the calculation of the concentration of fire gases on escape routes in the event of a fire do not allow one to account for the effect of antismoke ventilation with a great degree of precision. Mathematical modelling allows one to count with a sufficient degree of precision the concentration fields of smoke gases on escape routes. Results and conclusions. For the description of aerodynamic and heat mass transfer processes the equations of continuity, momentum, heat and substance transfer were used. The mathematical model of the propagation of smoke gases in evacuation routes developed using MatLab system was implemented which allow one to account for the effect of anti-smoke ventilation with a great degree of precision.
