## Abstract

Purpose. Forecasting the effectiveness of extinguishing fires by the underlayer method in tanks with oil products by calculating the time of foam lifting for tanks of various volumes.

Methods. The study used a theoretical method of mathematical modeling of the process of lifting fire-extinguishing foam in a combustible liquid, as well as an experimental method which consists in observing and measuring process parameters under specially created controlled conditions.

Findings. The developed mathematical model makes it possible to predict the foam lifting time by mathematical calculations using the foam lifting coefficient depending on the density of the foam, the density of the liquid in the tank, and the height of the tank.

Application field of research. The calculation of the time for extinguishing a fire in tanks with oil products will reduce the likelihood of fire spreading to neighboring tanks and reduce the unjustified consumption of fire extinguishing agents.
