At electric power enterprises, electrocution accounts for the largest share of fatal accidents, representing 55% of all deaths caused by electric shock. Most electrical injuries occur during the operation of external electrical installations, which make up 53% of incidents. This includes transformer substations, overhead power lines, and capacitor and converter devices. The most hazardous professions in these enterprises are electrical fitters responsible for repairing electrical equipment. Consequently, identifying risks and dangerous factors during the operation of electrical equipment is a critical task for preventing industrial injuries. The risk of hazardous situations can be assessed by combining the severity of potential consequences with the likelihood of occurrence during production activities. An analysis of professional risks and the main types of threats in the repair and maintenance processes of electrical equipment has been conducted. It was found that the basic risk level of electrocution due to deficiencies in an electrician’s work permit or violations of safety requirements is 48 points, which indicates an average risk level. This level suggests that the risk is unacceptable without implementing protective measures. Additionally, the risk level due to inadequacies in providing tools, protective clothing, and other personal protection equipment, as well as any malfunctions of such equipment, is rated at 54 points, indicating a high risk. Based on the results of the risk assessment during the operation of electrical equipment, the adequacy of planned safety measures can be evaluated. This assessment helps determine whether improvements are needed or if other safety measures should be introduced. To reduce the likelihood of traumatic situations and associated losses, appropriate safety measures are planned. These range from the complete elimination of hazards at the workplace to the requirement of using personal protective equipment.
