The tasks that need to be worked out during exercises to improve the safety and efficiency of the organization of air traffic are considered. The main problem in solving the problems of fire safety is the time to make a single correct decision when carrying out rescue operations. Recently, exercises involving all responding units have become widespread because they can help to work out the practical tasks of rescuing people and the most rational management decisions in conditions of limited initial information and the presence of many criteria that can not be foreseen. This article considers the issues of management and interaction of fire-fighting, rescue, canine and other services during fire-extinguishing and tactical exercises to organize fire-fighting and rescue of people in situations of aircraft accidents. On the basis of the accumulated world experience in aircraft accidents and the analysis of the consequences of various aircraft accidents, the methodological recommendations for training of rescue units in simulating emergency situations of aircraft in various variants of abnormal situations were worked out.

When the body of dams of various types is destroyed, the problems of interaction of water flows with soil from local materials and with the concrete base of the dam, as well as the development of filtration processes in the body of the dam, become relevant. This model allows us to describe both the mechanism of failure of mixed-type dams and the erosion of soil in the coastal zone, for example, formed as a result of a breakthrough wave, which leads to catastrophic consequences. To obtain practical results, there is a need to simplify the processes being studied. The main problem in problems of soil erosion by turbulent water flow is an adequate description of sediment transport. Typically, for these purposes, semi-empirical formulas are used, obtained for various conditions (extremely rarely specified) and giving very different results. In this work, to describe the processes of soil erosion, the theory of the bottom layer is used, which makes it possible to derive a formula for sediment consumption theoretically. The proposed model combines approaches developed in well-known models of continuum theory and hydraulics.

The paper describes the results of the experimental study of emission rates of passenger gasoline and diesel passenger cars and light commercial vehicles as a function of average speed from 5 to 50 km/h and accumulated mileage. It has been shown that the emissions of most modern vehicles with the mileage exceeding 100 000 km, regardless the initial environmental class, are quite of the same range as the emissions of vehicles without catalyst. It has been also confirmed that the highest emission rates are observed at speeds from 5 to 20 km/h, typical for traffic congestion, and the minimum emission rates are observed at speeds from 25 to 50 km/h.

The actual problem of improving the regulatory documentation on fire safety of rack-mounted inland water transport vessels used as hotels, restaurants and nightclubs, in which there is a significant number of visitors (mass stay of people), is considered. There is an increase in the number of such vessels, and, consequently, an increased risk of fires with severe consequences. The purpose of the work is to improve the regulatory framework for fire safety of moored ships. The study used the method of analyzing statistics and problematic issues of their suppression. The results of the work showed the need to assess the features of ensuring the safety of rack-mounted non-self-propelled vessels. Based on the processing, analysis and systematization of the data obtained, it will be possible to develop proposals for further implementation in legal documents and assess the feasibility of their application.

Fire protection of structures, as well as increasing the fire resistance of metal structures is an important task in reducing losses from fires. One common way to improve the fire resistance of a structure is to apply an intumescent flame retardant coating to the structure. Currently, expert practice has more often raised questions about establishing the presence or absence of fire protection on structures. The article considers the possibility of using the method of ion chromatography in order to determine the presence of fire-retardant components in the coating and determine the composition of the fire-retardant coating. The study was conducted on three flame retardant intumescent coatings with different binders. Two sample preparation methods were selected for the study: the study of directly aqueous solutions of intumescent coatings and the study of aqueous solutions of gases released during thermal destruction of coatings. Chromatograms of aqueous solutions of the tested coatings are given, indicating the presence of ions of fire-retardant components formed during hydrolysis. The results of the study showed that both methods have both advantages and disadvantages and can be used in preparation for analysis by ion chromatography to study flame retardant intumescent coatings.

. Using methods of regression analysis and neural network research, it was possible to preserve the physical properties of water-gene compositions and ensure a minimum time for extinguishing a fire in a model fire with components of industrial explosives. Neural network modeling was performed in the STATISTICA Application 10 program. The maximum discrepancy between the results of the neural network model and experimental data is 0,18 %. Regression analysis was performed in the REGRAN program. The maximum error in target results was 4,4 %. Analysis of experimental data and mathematical modeling results showed that the most significant properties of fire extinguishing agents based on hydrogels, providing minimal extinguishing time, are density and surface tension. The concentrations of the gelling agent were determined at which the water-gel composition acquires optimal physical properties for extinguishing a model outbreak of a component of an industrial explosive. Recommendations have been developed for creating hydrogel formulations with desired properties.
