我國近年來重大工廠災害事故，多數皆由於儲存產品原料與各式化學物質，在設備故障或人為操作錯誤，引發火災災害往往釀成重大災害事件，並常伴隨爆炸事故一併發生。有鑑於此，本研究利用火災模擬軟體FDS（Fire Dynamics Simulator）模擬桃園縣某半導體封裝測試廠在2005年發生之火災案例，探討半導體廠房火災發生的危險性及煙流危害評估分析。歷年來重大工廠火災事故，都造成公司停工無法營運外，還會影響到社會經濟及周遭環境的破壞。希望經由案例的研究，協助廠房進行工程改善、影響人員逃生的條件、納入未來新設廠房時之防火工程規劃設計中，以有效降低發生災害之風險及財物損失。並提供具體的規劃設計參數與量化數據，據以研擬適合國內需求之工業廠房重大火災防救對策，以及未來國家政策及法令規定制（修）訂之參考。

After 40 years of continuous development, semiconductor manufacture becomes one of the majorand perhaps most important industries in Taiwan. The manufacture factories usually store a largeamount of dangerous chemical substance/various product materials and are relatively easy to inducesevere fire incidents. Many plant fires occurred in the past 20 years and caused significant propertylosses. The FDS (Fire Dynamics Simulator) software is used to develop a computer simulationmodel for a typical semiconductor manufacture plant located in Taoyuan. The model is employedto investigate the energy and smoke transport during the plant fire accident occurred in 2005. Thefire characteristics are calculated to obtain the important variables within the various rooms of theplant. The results can be useful for the future improvement of the fire protection capability for themanufacture plant.
