Ergonomics Intervention Study of the RULA/REBA Method in Chemical Industries for MSDs'Risk Assessment

Workers in chemical industries, especially those who operate suspending agent workstations, face a risk of potentially developing musculoskeletal disorders (MSDs). This is because their work is often performed at high altitude or in dusty areas, and it frequently requires an awkward body posture because physical space may be limited. In order to reduce the risk of MSDs, researchers performed an ergonomic assessment using the RULA/REBA method directly at a workstation in a suspending agent area. Simulations were run using CATIA software to evaluate the designs of a conveyor, a jack-adjustable table, and the overall work method. This statistical study proved that work systems can be improved through the addition of specific tools, and that a worker's posture can be improved through the application of ergonomic principles. Software simulation provided a comprehensive solution for work-system development.
