Occupational safety model in maintenance operations: a case study of a service company

This article aims to implement a security model in a maintenance company to reduce accidents. The main problem is the high number of accidents recorded in the maintenance area, specifically 28 accidents in a 6-month period. Root causes are determined through a problem tree, and subsequently, tools such as the risk matrix, continuous IPERC, and safety procedures are assigned. The model was implemented in medium and low voltage electrical work, where a higher level of risk was identified through the risk matrix, specifically in the maintenance activities of medium and low voltage electrical panels, as well as in illuminated signs. Regarding the continuous IPERC matrix, it was developed for the identification and description of hazards and their sources in activities classified as more hazardous found in the risk matrix evaluation. Next, safety procedures were developed, with one for each more hazardous electrical job, detailing objectives, scopes, normative references, definitions, responsibilities, preventive measures, main procedure, PPE, and tools. By creating procedures for each hazardous activity, they were unified to form the main safety model. When implementing the model in the study company, results over two weeks showed a reduction in the number of accidents, thus achieving the main objective. The number of weekly accidents in the most hazardous electrical maintenance area decreased from 2 to 0. The uniqueness of this model lies in its specific focus on occupational safety in electrical work, particularly in medium and low voltage.
