Analysis of professional risks during reconstruction of engineering networks

Problem statement. Professional risks when performing work on the reconstruction of engineering networks, which are carried out, as a rule, in the cramped conditions of urban residential, administrative, cultural and industrial buildings, have not been fully studied. Therefore, in order to ensure safe working conditions during the reconstruction of engineering networks, it is necessary, as one of the stages, to perform a comprehensive analysis of occupational hazards and risks that accompany the technological processes of reconstruction. Purpose of the article − determination of the professional risk of personnel who are engaged in reconstruction of engineering networks. Conclusions. 1. Studies have shown that in recent years, the volume of construction work is constantly increasing, while the volume of construction work on engineering structures is approximately 51 % of the total volume of construction work. 2. The number of accidents at work has somewhat decreased and has been in constant condition since 2014. At the same time, the number of fatal accidents increased. 3. Occupational risk in the construction sector of Ukraine was within the range of 5,3∙10-4...2,9∙10-4 , which, in Ashby criteria for accepting risk, is an unacceptable risk. 4. The number of employees at risk of injury per hour of work has decreased, but the decrease in the number of employees in the industry should also be taken into account. Starting in 2016, this indicator began to slightly increase, while the number of construction works for repair and reconstruction, that is, those works that are mainly carried out in cramped conditions, has also increased since 2016. 5. In the first place in terms of the danger of professions whose representatives are involved in the reconstruction of engineering networks, there are truck drivers, installers and electrical fitters, and less dangerous are the foreman (head of department, group) and the reinforcer. 6. To ensure safe working conditions during the reconstruction of engineering networks, it is necessary to develop a methodology for managing preventive measures that will reduce occupational hazards and risks, taking into account the directions of violations of the technological process.
