| Summary: | 碩士 === 國立高雄第一科技大學 === 環境與安全衛生工程研究所 === 100 === Currently, automated production is widely adopted by the manufacturing industry, however, some jobs still rely on manual power; for most manufacturing factories, manual material handling tasks are still commonly seen and important on work-sites. Moreover, owing to limited working space, different material handling processes and time effectiveness, workers often need to perform manual handling operation by keeping poor working posture, instead of utilizing material handling tools or equipment to reduce the burden of hard work.
In Taiwan, work-related musculoskeletal disorders are not rare among workers; the causes are also complicated and quite controversial. By utilizing ergonomic technology to practically improve work equipment and environment on work-site and taking the “Key Indicator Method, KIM” developed in Germany to evaluate the following five work-site tasks: chemicals feeding, spool packaging, spool loading, spool lifting/ unloading and waste processing, this study aims at analyzing the causes, suggesting improvement strategies and further validating the performance of improvements.
After improving working posture through work-site enhancement, this study finds the risk level of chemicals feeding to be reduced from level 2 to level 1; the risk level of waste processing reduced from level 3 to level 1; and the risk level of spool packaging, spool loading, and spool lifting/unloading reduced from level 4 to level 1. In other words, after implementing improvement strategies, the risk levels have obviously decreased, which proves that the feasible ergonomic technology can facilitate workers working with correct and labor saving posture, reducing the risk of work-related musculoskeletal disorders and enhancing a safe, comfortable and sustainable work environment.
