The problem of operation of ineffective technical solutions for fire protection of gas stations against the background of an increment in the number of ones in connection with the intensive increase cars in cities. Technical solutions are proposed to improve the efficiency of the emergency fuel drain system from aboveground gas station tanks in a fire. The purpose of the work is to improve the system of the emergency drain of fuel from gas station tanks. Tasks: a) development of technical solutions that ensure the efficiency of the emergency drain system in case of fire in long-term operation and increase environmental safety; b) determination of the technical parameters of the system for providing the required time for emptying the tanks.

Investigations were made of the thermal stability of polyamide yarns modified with epoxy compositions. Single-walled carbon nanotubes «TUBALL Nanotubes» were deposited in epoxy compositions, astral and carbon. The analysis of the thermogravimetric characteristics of the samples is carried out (the temperature of the onset of thermal destruction and ignition of the substance, the thermal effect of the combustion reaction). Using atomic force microscopy, the structure of modifiers was studied. The results of the experiments confirm the possibility of using modified polyamide fibers due to their improved heat resistance indicators of firefighters protective clothing under conditions of hydrocarbon combustion.

We researched factors affecting the combustion products motion mode along vertically oriented channels of the smoke exhaust system. We proposed to neglect inertial forces, which involves studying the effects of three forces: gravity, aerodynamic drag, and overpressure. It is determined that the dependence of the gas flow pressure on the gas column height in a non-isothermal flow is nonlinear. It is shown that the flow of combustion products along a vertically oriented channel of the smoke exhaust system changes from laminar to the turbulent mode when a return flow appears. It occurs when the longitudinal velocity gradient is positive.

The article presents statistical data on the analysis of dangerous man-made phenomena at oil products supply facilities of the Russian Federation. The most frequently realized dangerous man-made phenomena and the most fire-hazardous objects in the structure of the oil product supply of the Russian Federation are determined. The definition, classification, functional structure, groups of objects related to the warehouses of oil and petroleum products are given. Results shown are theoretical some of the analysis of functional structures and systems of fire safety (hereinafter APB) warehouses of oil and petroleum products. The interrelation between features of the functioning of warehouses of oil and oil products and the reasons as a result of which there are fires and explosions is established. A number of actual problems in the SOPB of oil and oil products warehouses are revealed.
