The article considers the methodological approaches tо the definition of risk assessment of occupational risk,taking into account the analysis of occupational morbidity and class working conditions for individual professional groups.

Keywords: professional risk, analysis,evaluation,methodology,an integral indicator

The article considers the methodological issues of the economic assessment of damage from pollution, the difficulty of obtaining an objective assessment of the damage. Given shape ecosystem resilience to external influences as carrying capacity of the environment to the ejection of matter and energy into the environment as a result of economic activity. Carrying capacity of the environment is considered as a kind of natural resource potential of the rationale for the development of economic evaluation of the carrying capacity of a natural resource. The basic problems of economic evaluation of the implementation of the carrying capacity.

Keywords: Carrying capacity built-up areas, the economic carrying capacity assessment, the economic damage from pollution, ecosystem, the problem of realization of economic carrying capacity assessment

  In article it is disscused the basic of the methodological approach to improve the organization of the selection and implementation of measures to reduce occupational exposure of workers construction industry enterprises working under the influence of  high levels of noise.

  The results of experimental studies of a radial fan, built a complete characterization on the basis of the data listed in the table confirm the theoretical concepts and calculations. Goal is to determine the total pressure created by the fan, its supply and power consumption for each test mode. Designed and built the experimental setup, the department "Electrical Engineering and Automation" RGSU, which is designed for aerodynamic testing of the fan,

In article bases of a methodical approach to improvement of the organization of labor protection in the construction, based on a position of system risk management are considered. The methodical approach unites the block diagram and risk management model, provides efficiency of management of production safety, development of purposeful actions for decrease in risk factors, to elimination of the found violations of labor protection and their prevention further.

  The results of the analysis of existing approaches to the determination of the efficiency of trapping pollutants at their sources of isolation, as well as the prediction of residual contamination of the air of working areas. The classification of methods for determining the effectiveness of local suction ventilation systems. Given the technological distinction between the concepts (factor "technology capture") and sanitary (factor "technological breakthrough"), the efficiency of local suction. The tasks of improving the mathematical description of both types of efficiencies.

Keywords: pollutant, a local suction, efficiency, carbon capture, source separation, capture, simulation

  The article presents a method for the continuous monitoring of airflow in the ventilation system, that the department "Electrical Engineering and Automation" RGSU developed a method based on changes in the frequency and amplitude of the vibrations when the duct airflow. Designed and produced by the device based on piezo transducer prestressing. The principle of the device is based on the use of the frequency and amplitude of the vibrations of the air change rate of air flow. This method of continuous monitoring of air velocity in the duct registers change speed automatically and allows you to monitor the work of ventilation systems.

  The results of the analysis of existing approaches to solving the problem of propagation of impurities in the air and the prediction of residual contamination of the air of working areas. Presented by the rationale for selecting the method of "coarse particles" for the numerical experiment. We describe the nature and advantages of the method as applied to the calculation of the spread of contaminants. An algorithm for prediction of sanitary efficiency of the trapping of pollutants.
