Estudo ergonômico do posto de trabalho do operador de máquina de injeção de material plástico

Abstract

With the increase of the productive process observed in recent years, it is noticed that in many industrial sectors the operational load of the workers increased significantly causing them to make efforts that, many times, are repetitive causing several problems arising from the work activities developed. In this sense, in order to minimize these efforts, the main objective of this work is to analyze a workplace and suggest possible ergonomic improvements in order to avoid occupational health problems of the plastic injection moding machine operators. An Ergonomic Workplace Analysis (EWA) was performed, aiming to identify problems that could generate physical discomfort in the workers, and a microergonomic study using the method of the posture evaluation OWAS. The results showed that in some activities developed by the operator, there is a risk of injury due to back posture, related to the torsion movement of upper body. To minimize these efforts ecommendations were proposed with the purpose of reducing the ergonomic risks in the workplace analyzed.
