Development of methods for operational forecasts heat load on rescuers in fire fighting of burning resevoirs with oil products

Abstract

Purpose. The purpose of research is to develop the foundations of methods of operational forecasting the influence of external factors that determine the thermal load on the rescuers, for selecting anti thermal means to extinguish the burning tanks with oil.

Methods. Theoretical substantiation of dependence for operative estimation the radiant heat flow, and the expression for calculation of safe zones of conducting emergency works near the burning of oil products reservoirs.

Findings. It is received further development of the mechanism of heat load on the rescuer, including outside heat path from the source of burning and from the Sun, and inside (the heat dissipation of the body, regenerative work of respiratory system). It is established, that for external heat load are prevalent ray energy flows, and the other, as a rule, derivative of them. Geometrical dimensions of reservoirs for the storage of oil products predetermine the amount of energy radiated by fire. The dependence for operative estimation of the radiant heat flow, and the formula for calculation of safe zones of conducting emergency works near the burning of oil products reservoirs is substantiated.

Application field of research. Safe zone of conducting emergency works can be applied previously on the oil storage tanks plans, indicated in the operational documents. It is advisable to pre-label it in the terrain that essentially will protect personnel of the working parts of emergency services, especially arriving in accordance with the disposition.
