Abstract

This project presents the application of ergonomic intervention to reduce the risk of musculoskeletal disorders (MSDs) for manual materials handling tasks. Malaysia is one of the rapidly industrializing country in Asia region but it also faced challenges of the risk of MSDs. This is due to lack of attention on safety awareness in workplace. The major risk factors for MSDs are heavy manual material handling, repetitive tasks and awkward working postures. Since the manual materials handling tasks are contributed to the risk of MSDs, therefore this project was conducted to reduce the risk of musculoskeletal disorders for manual materials handling tasks by using RULA and Revised NIOSH Lifting Equation. The results found that MSDs experienced by the worker are caused by manual materials handling tasks. Then, ergonomics intervention approach was used to propose the materials handling devices and workstation design for safe working condition. Two materials handling devices and two new workstations have been designed by using CATIA software. Lastly, the effectiveness of the proposed design for working posture had been evaluated by using RULA analysis, however lifting limits are assessed by using Revised NIOSH Lifting Equation. From the evaluation, it can be concluded that the proposed design is capable to reduce the risk of MSDs for manual materials handling tasks in manufacturing industry.
