Avaliação de riscos ambientais e ergonômicos no trabalho de manutenção de máquinas florestais

Abstract

The activities developed in mechanical workshops aimed at maintenance of machines are inserted in a context that exposes workers to different risks in their work environment. For example, noise, vibration, and incorrect posture are common environmental and ergonomic hazards in this type of activity. In this context, it is important to carry out studies in work environments, in order to identify, evaluate and monitor possible risks and damages that may be influencing workers' health. In view of the above, this study aimed to evaluate the exposure of workers in the operational sector of forest machine maintenance to environmental and posture risks. The activities of general helper, electrician, lubricator, mechanic, welder and turner were evaluated. In the evaluation of workers' exposure to environmental risks, noise and vibration agents were considered. For the postural evaluation, the Fast Whole Body Evaluation (REBA) method was applied. The environmental noise agent presented itself as a high risk for the activities of mechanic and welder. The vibration levels are in accordance with the established by the legislation, being necessary only the maintenance of the existing condition. And in the postural evaluation, it was verified that there is a need for ergonomic intervention in most activities evaluated.
