近年來，我國因重體力作業所引起的肌肉骨骼傷害有愈來愈明顯的現象，歸納而言，主要的成因有五大項目。為了防制或降低肌肉骨骼傷害就必須要想辦法消除或預防這五大成因。本研究主要目的就是以化學原料廠例來說明應用人因工程手法改善於肌肉骨骼傷害防制的方法。本研究應用已發的人因工程姿勢圖例為輔來協助工作場所改善，同時利用KIM手法（KeyIndicators Method）來量化評估改善前後的差異性，並以NMQ問卷（Nordic Musculoskeletal
Questionnaire）來獲得現場工作人員對於改善的主觀感受。研究結果顯示，三個工作站改善
後，其KIM風險評估點數都有降低，而現場工作人員的主觀感受也同時都表示非常滿意。

In Taiwan, work-related musculoskeletal disorders (WMSDs) in strenuous works are becoming a serious occupational safety and hygiene problem in industrial countries. Five major factors are recognized as causes of WMSDs, and should be decreased or eliminated to prevent WMSDs. The
purpose of this study is to demonstrate the improvement of three workplaces by ergonomic principles for WMSDs prevention in a chemical company. A developed atlas was used to help the improvement, Key Indicators Meth-od (KIM) was used to evaluate the goodness of the improvement quantitatively, and Nordic Musculoskeletal Questionnaire (NMQ) was used to evaluate the improvement by the works’ subjective rating. In this article, a case of chemical company was studied, and three stations in it were improved with ergonomics intervention. The results showed that the ratings by KIM of three stations were reduced, the subjective ratings were better.
