Análise dos procedimentos, equipamentos e medidas de segurança na prestação de serviços em redes de distribuição de energia elétrica desenergizadas.

Abstract

This study was motivated by the interest in evaluating the safety conditions of workers involved in the maintenance and operation of de-energized power distribution lines and networks, due to the frequent work accidents in this sector. The main objective of this work is to analyze the procedures, equipment, and safety measures adopted by professionals who work in the maintenance of de-energized electrical power distribution networks. This will be accomplished by monitoring the activities of maintenance teams from an outsourced company of the local electric power utility in the city of Itumbiara, which will serve as a case study for the research. In order to provide support for the analyses, the NR-10 guidelines were presented, along with the company's internal safety standards, aiming to base the evaluations and ensure that the practices adopted are aligned with the established safety standards. The case study prioritized the observation of five essential factors for safety in electricity: work procedures, the collective protection measures adopted, the instruments and tools used, and the Personal Protection Equipment and Collective Protection Equipment. The analysis aimed to list the conformities and inconsistencies observed in the maintenance services of electrical networks, and to propose improvements related to safety during these activities. The intention is to improve safety practices and promote a safer working environment for the maintenance teams. After evaluating the procedures of the distribution network maintenance teams, it was concluded that all professionals are aware of the risks involved and the importance of following safety standards, using Personal Protective Equipment (PPEs) and Collective Protective Equipment (CPEs). It is recommended that the company reviews the contents of training and procedures, especially in relation to behavioral aspects of the professionals, in addition to intensifying the inspection and supervision routines in the services provided by its employees, in order to ensure compliance of standard procedures by norms, as well as the health and safety of workers.
