The purpose of this study is to analyze industrial injuries and assess the risk of injury to railway power supply workers based on mathematical statistics. It is shown that the level of injuries of this category of employees is at a significant level (the frequency coefficient of general injuries is higher by 2.6 times, and the frequency coefficient of fatal injuries is 5.7 times relative to the corresponding frequency coefficients in general for JSC “Russian Railways”). Based on the research results, the main causes of accidents with a fatal outcome were: poor organization and planning of work, violations of the technological process, violations in the use of personal protective equipment, lack of supervision on the part of the contractor, violation of work rules at the height, the extension of work place. The assessment of the risk of injury of contact network of electricians showed two possible types of accidents with them: electric shock and falling from a height. The probability of accidents is 0.031 and 0.051, respectively, with the number of injuries for each of the received scenarios on the five- year planning horizon being 7.85 and 12.75, respectively. The presented approach to assessing injury risks, supplemented by the method of expert assessments, will allow identifying and evaluating specific hazards at the workplace of linear level enterprises, respectively, to increase the effectiveness of developing of programs to improve working conditions and safety, and the effectiveness of implementing of tools for managing professional risks in order to reduce industrial injuries of employees of power supply divisions.
