Professional risks of contractor`s workers replacing the hydroelectric unit at Irkutsk hydroelectric power station

Abstract

The degree of occupational risk is an indicator that should be taken into account when managing the labor protection system. Timely identification of threat and their levels allows you to take measures aimed to reduce and (or) eliminate harmful and dangerous factors, thereby preventing injuries and occupational diseases. When assessing professional risks, jobs and technological operations of own personnel are often taken into consideration. However, the contractor’s personnel involved in the repair, adjustment and reconstruction of equipment is also exposed to dangers. According to the statistics on injuries at the energy enterprises of Irkutsk region for 2021, engineering companies account for the largest number of accidents. Based on a scoring with a 5x5 risk matrix, the study determined the level of occupational risks of contractor’ employees replacing the hydroelectric unit at Irkutsk HPP. The results can be used to identify measures required to reduce the level of risks to average (permissible) values.
