Research of fire development in multi-story buildings in cities of ukraine

The division of urban settlements into appropriate groups by population and area using the methods of cluster analysis. Statistical data characterizing the process of extinguishing fires by emergency rescue formations of cities have been processed. One settlement was selected from each group of cities and data on fires for the period of 2020 were further processed on them. The relationship of the following parameters is established: combustion area; floor of the building; time of fire localization. The obtained static data show that the area of the fire and the localization time increase on average from 3.5 to 6 times. The result of the data analysis makes it possible to calculate the amount of required extinguishing agents when using the method of discrete delivery.
