飛機維修人員負責基地飛機系統之維護,由於各項系統設備之配置,未充分考量維修人員於修護時之進手性及空間,維修人員常被迫於有限空間從事修護作業,且其修護作業均有時間限制。過去針對機場作業人員較著重於如有機溶劑及噪音等危害之探討,對於作業人員安全衛生認知及肌肉骨骼傷害則鮮少觸及。 在作業人員安全衛生認知方面,本研究利用問卷調查,以軍用飛機維修作業人員為受訪對象,問卷內容包括四部份:基本資料、安全衛生認知、工作技能及身體酸痛症狀。計完成215份有效問卷。在姿勢分析方面,採用OWAS及RULA姿勢分析方法,拍攝作業人員工作姿勢,於實驗室中以每15 秒定格畫面,計獲得1430張姿勢,依OWAS及RULA方法進行編碼及動作評估。 研究結果顯示,從事飛機修護作業曾有身體酸痛症狀者有203人,酸痛部位以頸部比例最高(佔71.3%),其次為肩膀(佔64.4%)、背部(60%)。姿勢分析方面,(OWAS)AC4的比例為15.5%(222張),(RULA)AL4比例為15.8%(227張),必須立即進行調查及改善,本研究提供改善建議並予評估。
The purpose of this study was to explore the musculoskeletal disorders for the fighter plane maintenance workers. The fighter plane maintenance workers is often forced to engaged working in the limited space. A structural questionnaire and OWAS and RULA postural analysis were used in the study. There were 215 subjects who are fighter plane maintenance workers. The structure questionnaire included four parts: personal data, attitude of safety knowledge,working skill and musculoskeletal complaints. OWAS and RULA technology was applied to analyze working postures in the study. After recorded in workplaces, the videotapes were played back and saved into computer in the laboratory with a freeze frame every 15 seconds. A total of 1430 working postures was coded and analyzed. Among the body parts, the neck pains was the highest (71.3%), followed by the shoulder (64.4%) and back (60%). For results of the OWAS and RULA postural analysis, the worker’s neck extension, trunk flexion and either hand above shoulder obtained high postural risks. The percentages of 15.5% and 15.8% with the OWAS and RULA analyses, respectively, for AC4 and AL4 were obtained. It implies that the action must be taken immediately. The results showed the same musculoskeletal disorder conditions from questionnaire survey and postural analysis.
