本研究將以某LED光電廠為例，由製程的原料_氨（Ammonia）及其廢棄物_氨氮問題進行切入，並針對該廠設置之「氨氮回收系統」加以探討工安管理問題及其對環保的效益；另外，運用「危害與可操作性分析（HAZOP）」之方法，研討與辨識出所有可能的作業危害，其中分析結果鑑別出19個不可接受與16個可接受但具潛在危害之工安風險；因應前述之分析結果，以「本質較安全設計（Inherently Safer Design, ISD）」的觀點，導入11項設計策略，進而將35個潛在危害因子消除或降低至可接受風險範圍，使該系統不僅能降低環保汙染議題外，更兼具安全操作等工安效益，達到工安及環保雙贏的局面。|
Light-Emitting Diode (LED) optoelectronics industry is one of the fast-growing technology industry in recent years , but the process raw materials or related waste (including waste gas , waste water , waste materials, etc.) emission or consequences of misuse of the accident , has apparently caused industrial safety problems and ecological environment of the real impact. At domestic and abroad, a considerable improvement regulations and stringent regulation of chemicals and waste emissions standards has been implemented, and the industrial safety requirements are becoming more stringent ; therefore , how taking into account the safety for workplace requirements and reducing the impact of waste on the environment , are all in front of an important issue. This study will take a LED light plant as an example, investigate its process of raw materials _ammonia, waste_ammonia, nitrogen problems and issues to be explored industrial safety management for the plant set of " ammonia recovery system " for its environmental benefits ; wherein the use of " hazard and operability study (HAZOP) " method , the research and identify all possible hazards of the job , also the result show us 19 unacceptible hazards and 16 acceptible but nearly dangerous hazards. Because of the result, we elaboration preferred coping responses; and finally, to "Inherently Safer Design (ISD)" point of view , ammonia and nitrogen recycling system safety factor which should be considered with the 11 stratages in the design , so that the system can reduce the environmental pollution issues , but also benefit both for the industrial safety design , safe operation , industrial safety and environmental protection to achieve a win-win situation.
