Problems of culture of work, as a necessary element of forming a culture of safety, one of intensively developing directions of modern educational theory and practice. The work culture is seen as a complex subsystem of General culture of a person. The aim of the research is the analysis of the structure of forming a culture of safety. As the method is used theoretical analysis. There were two main blocks - obserwowac culture and professional culture of the engineer. Obserwowa culture develops ideas about the kinds of work and working methods, positive work attitudes, personal readiness to mastering the skills of General and professional. In the professional culture of the engineer were divided into three components: information, organizational and innovation. The availability of information culture of a specialist implies the possession of theoretical knowledge, practical skills and abilities. As part of the organizational component of professional culture tanned such components as the workplace organization, creation of safe and harmless working conditions. Innovative component provides support and development of creative potential of personality. Thanks to the work culture, people are not only able to meet their physical needs, but also to solve problems of self-development, self-improvement and self-esteem.

Keywords: culture of safety, the culture of work, obserwowa culture, professional culture, information culture, a culture of innovation.

analysis of the conditions of movement of vehicles on the roads has shown that special difficulties arise in the winter. This is due to the quality of the work of snowplows. One problem is the snow removal for road barriers. In line with this, and considered the possibility of the need to improve, creating a Russian-made snow plows. Based on the analysis of schemes snow removal from roads, structures working bodies with piles of snow plows, proposed a new design that allows for snow removal for road barriers, as well as the proposed use of a working body under a snowplow clearing patrol roads. At the expense of achieving the universality of cars increased their rate of use and, therefore, the payback period. The effectiveness of implementation of the new structure of the working body of the snowplow is achieved by reducing the amount of used equipment and passes undertaken during snow removal

Graf-lattice has vertices at points with non-negative integer coordinates. From each vertex has two arcs: horizontal and vertical neighboring vertices (right and top). The transition probability for each of the arcs is equal to ½. Consider the problem of random walks on the vertices of the graph, without limitation on the achievable and with two types of limitations on achievable - mixed and magnetic. There is some combinatorial identities containing binomial coefficients from different layers of Pascal's triangle.

The problem of infrastructural limitations of approaches to the sea ports of the Southern region is considered in the article. The analysis of handling and carrying capacity of railway and port infrastructures is given. The calculation of available and needful carrying capacity of railway sections is carried out. The construction of double-track spans on the final stage of design of the approaches to the transportation junctions is suggested.

In the framework of the given article shall be considered a negative impact on microorganisms of ions of zinc, copper and Nickel concentrations in the incoming wastewater to the wastewater treatment facilities of the cities of the Lower Volga region is unacceptably high, which inevitably reduces the quality of the purified water at the indicated metals exceeding the output after biological treatment is more than 30 times). Further, in the proposed article, we describe the results of studies aimed at disposal and treatment of waste activated sludge. The first attempt to use the resulting after biological purification of waste as a secondary raw material for the adsorption material, which retrieves the designated heavy metal ions from wastewaters prior to biological treatment, which allows further the activated sludge fully interact with other ions without losing their functions. As a result, after the biological cycle treated water at the indicated metals, meets the relevant standards.

The calculation of technological and economic losses caused by emission of electrolysis hydrogen in the atmosphere is made. The flow of oxygen and air during the combustion gases and the amount of simple combustion is calculated. The ways of economically viable utilization of associated hydrogen would increase the level of environmental safety of the process are revealed. We consider the use of hydrogen produced during electrolysis of sodium hypochlorite solution to produce hot water for the needs of the enterprise. Proposes the use of snow in the territory of the water supply enterprise as a backup element for the implementation of resource-saving technologies for potable water.
