Within the framework of the integral mathematical model for the building fire’s initial stage, the increments of the gas medium temperature in the initial stage of a fire development in buildings have been determined, and estimates for these increments have been presented. The dependence between the gas medium temperature’s relative increment and the burn-up rate’s average value has been established, and an estimated formula for the relative temperature difference over a given time period has been obtained.
