隨著半導體與高科技製造產業持續升級，潔淨室運轉廠房已成為高度精密製程之核心環境。在設備世代更新與製程調整過程中，須經常於運轉中潔淨室內實施消防管路設備施工與維護作業，而此類工程具有高處作業、動火作業、系統誤啟動、氣體釋放、生產中斷等多重高風險特性。因此，本研究以任務危害分析(THA)為核心方法，依據勞動部2015年「作業安全風險評估技術指引」建構風險矩陣模型，並研究透過文獻回顧、現地觀察、專家訪談及文件蒐集，針對實際運轉中潔淨室廠區之消防工程進行系統性拆解，涵蓋即早期偵煙探測器設置與驗收、CO₂滅火系統保養、撒水頭移位、偵煙探測器更換、乾粉系統維護、消防電力配線工程、等六大類施工情境，共辨識40項高風險作業步驟與潛在危害。研究結果顯示，高風險來源主要集中於高處作業墜落風險、動火作業引發火災、消防管路誤拆造成大規模水損、CO₂或乾粉系統誤啟動導致窒息及潔淨室污染、鍍鋅消防管內鋅氧化產生氫氣累積等。經風險控制措施實施後再評估結果顯示，多數原屬高度風險之作業步驟可有效降至中度或低度風險等級，亦證實THA方法於潔淨室施工情境具高度可操作性與預防效益。本研究之主要貢獻包括建立融合人員安全、環境影響與營運衝擊之潔淨室施工風險量化模型，同時提出適用於運轉中高科技廠房之消防施工風險管理架構，對提升高科技廠房施工安全與營運穩定性具實務價值。

This study examines job safety risk assessment for fire protection piping construction conducted within operational cleanrooms in semiconductor and high-technology manufacturing facilities. Equipment upgrades and process adjustments often require modifications to firefighting piping systems without interrupting production, creating compounded risks such as work at height, hot work operations, system malfunction, gas release, and operational disruption. The objective is to develop a structured and quantitative risk assessment model suitable for these complex environments. Task Hazard Analysis (THA) was employed to construct a risk matrix integrating personnel safety, environmental impact, and operational loss into the severity dimension. Six categories of firefighting construction activities were analyzed, identifying 40 high-risk operational steps. The results confirm that the THA-based framework effectively enhances construction safety and engineering management in operational cleanroom environments.
