INDUSTRIAL HAZARDS DURING THE MAINTENANCE AND REPAIR OF ELECTRICAL EQUIPMENT

Abstract

Purpose. Purpose. The purpose of this work is to substantiate a list of possible hazards for workers during the repair and maintenance of electrical installations and to justify measures to prevent them.

Research methods. The methodology for analyzing hazards during the repair and maintenance of electrical installations is based on well-known risk analysis methods that are widely used in global practice when assessing hazards. The analysis of hazard factors involves studying the adverse effects of hazards on objects of influence and justifying management decisions to reduce the level of risk.

Results. The study identified the main hazards associated with the repair and maintenance of electrical equipment, in particular those leading to high levels of electrical injuries (over 55% of all fatalities in the industry). It was established that the key sources of threats are the admission of untrained personnel, the unsatisfactory condition of outdated equipment, violations of technological discipline, and the lack of proper use of personal protective equipment. A hierarchical system of safety measures has been developed, covering the complete elimination of hazards through modernization (replacement of overhead networks with cable networks), the implementation of engineering and technical solutions (ventilation systems, locking, fencing), as well as organizational measures and the use of personal protective equipment. The need for a comprehensive approach to risk management that takes into account both regulatory requirements and specific working conditions at specific workplaces has been proven.

Scientific novelty. It consists in systematizing and detailing specific threats in the work of an electrician repairing and maintaining electrical equipment. For the first time, attention is focused on the need to adapt hazard identification to martial law conditions, in particular due to the emergence of new risks associated with massive attacks on energy infrastructure and the elimination of atypical accidents.

Practical significance. A list of input data and methods for obtaining it has been developed for the effective identification of hazard factors at electric power enterprises. Practical recommendations have been formulated for the selection and combination of technical and administrative protection measures that can be used by enterprise managers, occupational safety services, and specialists to reduce occupational injuries to an acceptable level. The results obtained can be integrated into hazard identification cards and staff training programs.
