The paper proposes and substantiates the approach to the location of fire hydrant kits in the plan of the building, which is one of the main areas of implementation of the required level of its fire protection system. It is determined that the location of fire hydrant kits is a must to ensure irrigation of each point of the room with the required number of jets, which affects the success of the use of internal fire water for firefighting. The parameters influencing the location and number of fire hydrant sets in the building are investigated. It is shown that when using fire hoses of maximum length, the radius of the fire hydrant set increases and their required number decreases accordingly. The diameter of the fire hose affects the water consumption obtained from the crane set and must be at least standard. It is shown that when choosing the number of fire hydrant sets, in addition to the characteristics of their equipment, it is necessary to take into account the design features of the room and the standard number of jets, which significantly affects the economic component. The principles of placement of the main and additional fire hydrant sets for different number of jets at each point of the room are investigated. Based on the analysis of parameters that affect the number of fire hydrant kits in the plan of the building, an approach to the placement of PAC on the principle of their reasonable sufficiency. The efficiency of the proposed approach to the placement of fire hydrant kits is established. Evaluation of the effectiveness of the proposed approach to the placement of fire hydrant kits showed that the rationale for the decision on the number of main and additional fire hydrant kits in the building allows to meet regulatory requirements for irrigation of each point of the room with the required number of jets. protection.
