Method involves determining for one linear input of a subsurface fire-fighting system the total length and inner diameters of foamer solution lines, extending from the room with electric drive valves to high-pressure foam generator assembly (HFG), foam lines passing from HFG to rupture membrane and inside the tank. Then the consumption of foamer solution and the foam expansion ratio are determined, after which the time interval needed to fill the foamer solution lines with foamer solution and foam lines – with foam is determined, foam line passing from HFG to the rupture membrane. Value of pressure at which the membrane breaks is determined. It is followed by calculating the time interval needed for pressure in the foam line to reach the value at which the membrane breaks, and calculating the time interval between the membrane rupture and foam filling the foam line inside the tank. Speed of foam floating to the surface of the liquid is calculated and time interval needed for foam to float to the surface of the liquid is calculated.
