人因改善方案對減輕晶圓製造廠現場作業女性員工肌肉骨骼危險因子與不適症狀之影響

The Effects of Ergonomic Intervention Program on Reducing Musculoskeletal Risk Factors and Symptoms among Female Semiconductor Fabrication Room Workers

指導教授 : 詹長權

摘要


本篇論文之目的為評估人因改善方案應用在職場的成效,內容包含兩大部分,第一部分針對晶圓製造廠推動的人因教育訓練課程進行成效評估,藉由現場訪視問卷,追蹤調查對減輕現場作業女性員工肌肉骨骼危險因子(包括上肢、背部及下肢、及人工物料搬運)之影響。研究結果顯示訓練內容沒有明確量化說明及沒有實際工程設備改善,實施教育訓練顯然無效;但對降低背部及下肢,以及部份人工物料搬運危險因子有效。第二部分針對電腦工作站改善進行成效評估,收集現場四十位員工自填問卷及做實際觀察,評估符合人因設計之電腦工作站對減輕晶圓製造廠現場作業女性員工肩部肌肉骨骼危險因子及不適症狀之影響。研究結果發現改善組員工在介入後一個月顯著降低肩部危險因子及不適症狀。三個月之後,改善組員工仍無肩部不當作業姿勢;但對於重覆性作業及員工肩部不適症狀成效則只維持一個月。後來經過探討分析發現,肇因於改善一個月後員工平均使用電腦的時間增加;由此可見使用符合人因設計之電腦工作站的確能有效降低肌肉骨骼危險因子及不適症狀,但仍需搭配作業時間長短的管理。未來工業衛生師能參考本研究結果及建議,更有系統性地評估作業環境的人因危害及推動職場人因工程介入方案。

The objectives of this thesis are to evaluate the effectiveness of ergonomic intervention program on reducing female semiconductor fabrication room (fab) workers’ musculoskeletal risk factors (MRF) and musculoskeletal symptoms (MSS). There are two parts in this thesis with Part 1 aiming at ergonomic education and Part 2 targeting at ergonomically redesigned workstations. By following up 34 fab workers for 9 months in Part 1, this study showed that ergonomic education was effective in reducing all back and lower extremity risk factors and most manual handling risk factors. By contrast, this study showed no educational effect on reducing MRFs for all upper extremity and some lower extremity. By prospectively studying 40 fab workers, including 20 workers using ergonomically redesigned workstations in the intervention group and another 20 workers using original workstations in the control group, for 5 months in Part 2, this study showed that the intervention group’s MRFs of awkward shoulder postures and repetitive motions as well as MSSs in shoulders were significant lower than the control group’s one month after intervention. The lowering effects persisted for three months on awkward shoulder postures but lasted for only one month on repetitive motions and shoulder symptoms after intervention. This thesis’s findings are useful for industrial hygienists in designing or evaluating their ergonomic intervention programs in the workplace in the future.
