The working conditions of the combine operator are investigated. It is revealed that the leading occupational hazards of the worker are microclimate adverse parameters. Based on the analysis of the harvester cabin thermal state during summer and winter operation, a system of microclimate normalization is proposed, for which the main functional characteristics — cold and heat capacity — are determined. According to the calculation results, the relationship between these characteristics and the operating speed of the combine is established. Computer modelling of heat and mass transfer in the conditions of active ventilation of the cabin allows us to get a more detailed picture of the formation of streams of air movement and temperature in the working area of the operator and to recommend measures of thermal protection.

The paper considers hazards of production factors and engineering solutions to labor protection based on physical laws taking into account new solutions of scientific and technical progress. This study will allow implementing labor protection measures in design and development, as well as in industries. The development and implementation of safe equipment, safe methods and types of work includes a wide range of solutions that can ensure the safety of certain types of work, improve working conditions. The paper considers these issues on the example of the design and operation of a mixer truck.

The reasons of overuse of production capacities at storage and processing of vegetable raw materials are determined. The growth rates of gross output of grain and leguminous crops are considered. Elevators, objects of flour, cereals and feed production are considered as important structural elements of micro and macroeconomics. The paper predicts the application of digital technologies in production control and online monitoring of dangerous and harmful production factors. Ways of implementation of this approach on real production processes, which are, controlled both by the operating organization and by the Supervisory authorities are considered. Accidents and fatal injuries at hazardous production facilities of storage and processing of plant raw materials are considered.

The electromagnetic field (EMF) poses a serious threat to human life and health. The biological effect of EMF exposure in a long-term exposure accumulates. The result of this may be degenerative diseases of the central nervous system, blood cancer (leukemia), brain tumors, hormonal diseases, and malfunctions of certain organs and the human body as a whole. The purpose of the work is a theoretical assessment of the danger of electromagnetic situation in the area of Rostov-onDon television center. The task is to determine the dangerous and harmful zone for the population due to the electromagnetic impact of the television center. The authors plan to: find the electric field strength taking into account the television center power transmitters, antenna amplification and the distance to residential facilities; determine radiant exposure at different distances from the television center; compare the results with the MPL of EMF radiant exposure taking into account sanitary and epidemiological requirements; find ways to protect residents from EMF effects. The result of the research is the theoretical assessment of the electromagnetic situation near the station. The dangerous and harmful zone for the population and the compliance with the sanitary norms and rules of placement of radio-television and radar stations №1823-78 are determined. The objects of the Zheleznodorozhny district of Rostov-on-Don the inhabitants of which are exposed to electromagnetic waves are specified. Ways of protection of inhabitants from EMF are found.

The issues of ensuring the reliability of equipment in order to improve the safety of its work are considered. The article proposes a method for modeling a general population of a finite volume using small samples of input data. The optimization of truck maintenance intervals is provided.

The paper considers the main systems for monitoring elevator equipment condition, their tasks and functionality. The dependence of the degree of elevator load on the number of storeys of the building is considered. The paper provides options for expanding the possibilities of dispatching systems for better safety of elevator structures.

The paper provides the analysis of the results of a multi-year monitoring of pollutant emissions from motor vehicles and stationary sources recorded in Rostov-оn-Don. Conclusions on the composition, structure and scope of these emissions are drawn. The authors prepared a database covering 2009-2016 years to build mathematical models of atmospheric air pollution.

The article considers an actual problem of accounting of fires and their consequences. Based on the analysis of international experience and normative documents, it shows that the existing norms do not meet the modern requirements of legislative acts and require significant updating. The article provides the main ways and directions of normative documents updating for their efficiency and compliance with the legislation.

This article analyzes traffic accidents in the Rostov region in 2018, their main causes, dependence on time of day, driving experience, age of drivers. Methods for reducing accident rates are proposed. There is a decrease in the number of road accidents compared with 2017 on the example of statistical data provided by the State Road Transport Inspectorate and posted on the Internet. Options for conducting additional internships, contests of knowledge of the road traffic regulations, driving skills competitions, road rally, methods of speed limit remote control, comfortable driving, introduction of driver physical monitoring systems, introduction of vehicle technical condition monitoring systems, fault indication systems are considered. Special attention is given to the use of risk-based approach in road transport enterprises and risk class reduction.

A model has been built for estimating the degree of uncertainty in making technical decisions. It is based on a comparison of the results of decisions made (training sample) with their assessment based on indicators adopted for the intended decision making.
