Análise ergonômica do manuseio manual de cargas em uma indústria de laticínios: um estudo de caso utilizando a equação do NIOSH e o método REBA

Abstract

This study aimed to conduct an Ergonomic Work Analysis (EWA) in the mixing subsector of a dairy industry, focusing on the input feeding task. The methodology involved the application of the EWA for qualitative assessment, supported by the NIOSH Equation and the REBA Method. The EWA results indicated critical environmental risks, such as slippery floors and the constant need for washing, as well as the risk of accidents caused by the loading platform falling onto the feet. The NIOSH evaluation revealed a Lifting Index (LI) of 5.02 for long-duration shifts, indicating extreme risk. Complementarily, the REBA method yielded a final score of 10, classified as high risk. The integrated discussion demonstrates that the biomechanical overload and environmental conditions are inadequate, requiring immediate interventions to preserve the worker's physical integrity.
