Depth of extinguishing as a criterion for effectiveness of management of combat operations to extinguish a fire in residential buildings

Abstract

Introduction. The article substantiates the use of the depth of fire extinguishing by fire-fighting hoses for estimating the possibility of localization of fire in the management of combat operations in residential buildings. On the basis of the criterion in a generalized form a block-scheme of the generalized algorithm of the decision-making support of the fire extinguishing manager, which makes it possible to determine the possibility of localization of the fire by the available water fire-fighting hoses, is offered. A theoretical substantiation of the value of depth of fire extinguishing with direct fire-extinguishing jets in not-large squares of rooms and a functional dependence of the depth of extinguishing on the water pressure before the fire hose nozzle, which raises the calculation accuracy, is given. Goals and objectives. To evaluate the possibilities of localization of the fire by the available means and, as a whole, to increase the efficiency of fire-extinguishing management by the fire-division in the multi-story dwelling buildings. Increasing the calculation accuracy of the depth of fire extinguishing. Methods. Using the depth of fire extinguishing as an efficiency criterion in estimating the effectiveness of fire fighting with water fire-fighting units. The comparison of the actual value of the criterion with the required value determines the possibility of localization of the fire. Conclusions. The use of extinguishing depth as a criterion of effectiveness can serve as a basis for new methods and models to support the management decision-making of the fire extinguishing manager. The depth of fire extinguishing can be calculated as a function of the head before the nozzle of a fire-brigade can be used as a criterion of efficiency of the management of a fire-unit armed with water fire-brigade. Key words: fire, management, decision-making support, algorithm, efficiency criterion, depth of fire extinguishing.
