The assessment of the protected evacuation of the population from the fire zone at social facilities in the service sector on the basis of numerical modeling methods has been carried out. The time of safe evacuation of people from the object on the basis of a basic mathematical model for monitoring fire hazards for a specific social object has been regulated. Correlations between the degree of heat and the fire duration have been recorded. Partial concentration of O2, CO2, CO, HCl, measures of smoke aerosol opacity from the fire duration using “Fogard” software package configured for simplified analytical model of human flow have been captured. On the basis of the developed mathematical model of fire development design solutions that provide a secure evacuation of the population from the object have been proposed. The calculation of the blockade duration of routes and passageways for sending people out of the fire zone was made using deterministic fire indicators has been performed.
