Introduction. To date, fires in high-rise buildings are one of the significant problems faced by fire protection units. Unique objects require a special approach in terms of fire safety and fire extinguishing. The most important task is to ensure the supply of extinguishing agents to the height using modern fire-fighting equipment and installations.Materials and methods. In September 2021, to conduct experimental scientific and tactical exercises on the roof of the Neva Towers tower, a program and methodology for supplying fire extinguishing agents in various ways to the height were developed. The following methods of feeding to height were considered: deployment using the equipment of a container for high-altitude firefighting, feeding from an installation with compression foam technology, feeding using a waterjet cutting unit “Cobra”.Theoretical bases. A theoretical assessment of the possibility of supplying extinguishing agents to a height with the help of new fire-rescue equipment confirmed the need for experimental scientific and tactical exercises on the roof of the Neva Towers tower.Results and discussions. As a result of the scientific and tactical exercises, the effectiveness of the use of new fire extinguishing systems with compression foam supply, as well as installations with waterjet cutting technology “Cobra” was proved. It was possible to provide a feed to a height of 350 m.Conclusions. To date, with the help of new fire extinguishing technologies, it has been experimentally proven that their use is most effective compared to “traditional” methods of supplying extinguishing agents. In the future, it is necessary to conduct more detailed studies of the hydrodynamic parameters of pumping and bag systems in order to develop recommendations for preliminary planning of the actions of forces and means of fire and rescue units.
