How to perform an ergonomic analysis of a workstation

Abstract

In the face of numerous complaints about upper limb pain of employees involved with a printed circuit board (PCB) assembly line, there was a need to assess the level of Work-Related Musculoskeletal Disorders (WRMD). To solve this problem, the research aimed to perform an ergonomic analysis in a workstation of an assembly line of a company X of the Manaus Industrial Pole (PIM). Therefore, the risks of WRMD were evaluated and the problems faced were diagnosed, to propose improvement actions to adapt the work environment to the workers. With the aid of the Ergonomic Work Analysis (EWA) method and the Rapid Entire Body Assessment (REBA) method for the assessment of the risks of WRMD, it was found that the operator was subjected to an average risk of WRMD and that the intervention for resolution or risk minimization was required. The operator's complaints were a pain in the shoulders, arms, and neck. In the end, five recommendations were suggested to company managers to solve or mitigate the problem.
