摘要

1. A method of fire fighting localized in volume and / or area of fire fighting in fire-hazardous areas of buildings and installations, in which the fire-extinguishing agent is supplied from a piping system horizontally located in the structure with branches and shut-off valves to the vertical hollow structure supports from the section of the fire-extinguishing valve means, and in case of fire, finely spray or spray under pressure in a certain amount and with a certain duration using spray nozzles, while locking the cl Panes, after detecting a fire source, are opened using detection means to unlock the extinguishing agent, generate an initiation signal, and at the same time, with the help of a central control center, give an alarm, give at least one fire warning to the relief site, turn on the extinguishing agent, and turn off the electrical and fire-hazardous installations, characterized in that around the source of fire and / or in fire-hazardous areas create at least one wall of extinguishing agent from sprayed to prevent the spread of the thermal load to other zones along at least one vertical and / or horizontal spray plane passing between the supports that are associated with the fire source, respectively, the fire hazard zone and controlled by means of detection, and / or at least one additional a wall of extinguishing agent made of spray fog to protect and cool the escape routes, access roads, openings in fire walls and technical equipment inside buildings
