THE INFLUENCE OF WATER MIST FIRE-EXTINGUISHING IN CASE OF FIRE IN HIGH-RISE BUILDING

Practice shows extinguishing fires in high-rise buildings is achieved by using a compact water on the outside of the building. Modeling fire to temperature in the rooms of the building is dangerous for concrete values. Therefore, the termination of a fire, the initial stage of the transition to a fire in an advanced stage. If there are people in buildings only way is to use a water mist systems. The application of this method allows, according to calculations, to stop the fire for 5–6th minutes after its occurrence, avoiding to the development of dangerous temperatures. Development of the extinguishing fire system in a tall building consists of several stages: the division of the building on fire compartments; evaluation freely developing fire in separate compartments with the greatness of the fire load on the floor isolated compartments; the impact on the parameters of water mist fire compartments skyscraper.
