The article deals with the assessment of risks associated with safety. A study on the materials of a special assessment of working conditions (SOUT) in the processing industry. The risk factors affecting the health of workers are described. The calculation of the risk assessment of the impact of classes of working conditions and harmful production factors in the workplace and workers according to a special assessment of working conditions. According to the results of the study and assessment of risks of labor protection revealed that the largest number of jobs and workers are affected by noise and the severity of labor, for which the risk values are among the largest and correspond to high (intolerable) risk. Recommendations on risk management strategy are given.

The paper deals with the organization of the dispatching of elevators, as one of the important conditions for ensuring security, and monitoring the technical condition of elevator facilities through the use of digital technologies. This method allows to increase the safety of the operation of elevators, to ensure the operational control of the state of the elevator structures both by the operating organization and by the regulatory authorities, and to reduce the negative impact on the safety of the human factor.

The article is devoted to the analysis of physical essence of the process of air pollution reduction for the woodworking shop of the enterprise serving the objects of urban development, within the framework of physical and energy approach. According to this approach, wood dust is considered from the position of disperse systems theory, which changes its properties under the influence of external disperse systems. The whole process is gradually illustrated by a physical model of air pollution reduction process, as well as a scheme of transformation of the disperse system (dust aerosol) in the process of air pollution reduction.

The article analyzes the factors and causes of the occurrence and development of accidents at oil products supply facilities. It is shown that the main causes and factors of accidents are the presence of large amounts of oil and oil products at the facility, which are explosive and flammable substances, transportation of oil products under high pressure, operation of equipment under pressure at high temperatures, the presence of periodic processes and transient conditions of equipment as well as the corrosive activity of oil and oil products (especially with sulfur compounds).

The authors have developed an integrated method for occupational risk assessment at the enterprise, taking into account statistical data from 2008 to 2017. The analysis of occupational accidents has shown that occupational risk assessment should consider competence of workers, working conditions, accidents at production, not connected with the human factor. Matrix of harm and the severity of that harm is calculated for each accident factor. The essence of the method is that for each situation the specialist determines the rank of probability of its occurrence and the potential damage corresponding to this situation. According to this practice, risk can have three meanings: "unacceptable", "high" and "acceptable". The value of risk is determined as the intersection of the categories of employee competence, working conditions, accidents at work, not related to the human factor. Thus, an occupational risks assessment and management system is developed aimed at preserving life and health of employees, taking into account statistical data on accidents from 2008 to 2017. The results of the study allow us to conclude that the high level of competence of the employee in the field of labor protection can significantly reduce occupational injuries, despite the harmful working conditions and the high risk of an accident at work, which is not associated with the human factor.

The article describes the main indicators of the situation with fires in the Republic of Crimea and Sevastopol.

Their comparative analysis with values of indicators of a situation with fires across Russia and the southern Federal district is carried out.

It is shown that the average number of fires (per 1,000 people) in the Republic of Crimea and Sevastopol is less than in the southern Federal district and the Russian Federation as a whole in 2017. On the basis of the conducted research the directions of increase of combat readiness to performance of tasks on purpose of divisions of fire protection of the Crimean Peninsula are defined.

The purpose of the analysis is to determine the complete picture of accidents and injuries of personnel with fatal consequences at explosive storage and processing of plant raw materials. The analysis is aimed at comparing data on the types and causes of accidents, as well as comparing data on fatal accidents, taking into account the risk and prevalence of traumatic factors. Along the way, the analysis of the impact of Supervisory activities on the safety of hazardous production facilities engaged in the storage and processing of plant raw materials was carried out. A comparison of the number of hazardous production facilities in different periods of time and the number of accidents and accidents occurred.

The analysis of the combined populations of «predator–victim». Based on the discrete data of the growth of the population by years determined a rough plan of the regulation of population size. The cases of the location of the two predators in the area.
