Gerenciamento de risco em manutenção: aplicação da análise preliminar de risco em serviços de instalações elétricas

Abstract

Work safety becomes an increasingly ruling factor in quality, productivity and value that companies apply in their organizational culture. Therefore, the present study aims to analyze the risks which workers performing electrical maintenance are exposed, raising the most critical activities through the application of a Preliminary Risk Analysis (PRA) by utilizing questionnaires and interviews to identify the risk perceptions of the employees involved in such activities. With PRA application, starting from monitoring the accomplishment of activities executed by the maintenance team of the building electric power substation, potential risks were identified, recommendations were generated to prioritize such risks, since the intention is to act efficiently to minimize the risks and to control them. Thus, the results obtained led to the conclusion that the application of PRA during maintenance of an electric substation identifies a series of risks, which, inevitably, if not managed effectively, will increase the potential of injuries, harming the workers and subsequently a company's reputation. The main risks identified were electric accidents, inadequate postures, working at heights, dust & fumes and other minor injuries. The main actions to prevent such incidents are: training to raise awareness of accident prevention, use of Personal Protective Equipment and the use of adequate tools that will minimize the cited risks.
