Abstract:	本研究主要針對工業區進行量化風險評估，利用SAFETI量化風險分析軟體來進行，其中我們有些需要考慮的因素有：地區人口資料、工廠及運作毒性化學物質資料、地區之大氣條件。在本研究中地區人口資料主要是由該地之區公所提供之資訊；工廠及運作毒性化學物質資料，主要是由北區環境事故專業技術小組所調查統計之資訊；地區之大氣條件則參考交通部中央氣象局的氣候統計資料所取得之該地觀測站的資料，接者再將上述資料加以整理為所需之參數。整理完畢後，在氣象條件氣溫29.34°C、壓力1001.62hPa、濕度75.16％、風速1.85m/s以及大氣穩定度D下進行量化風險評估，並參考毒性化學物質之容許濃度、各國個人風險及社會風險指標。結果發現該工業區內有些工廠運作之毒性化學物質的危害風險非常高，分別為B2(聯胺)、F3-7(聯胺)、F5(甲醛)、H2(丙烯腈)、K1(丙烯腈)、M3-1(甲醛)及M3-2(甲醛)，這些工廠一旦不小心發生洩漏災害，危害範圍將會波及至工業區外，將會對周遭的人們和環境造成非常嚴重的後果，若要降低危害風險，就必須要針對這些工廠運作之毒性化學物質加以規範，並使其降低危害風險，使得個人風險及社會風險值降低至可接受風險範圍。 This study focuses on quantitative risk assessment in the Industrial Park, using SAFETI quantitative risk analysis software, some of which we need to consider: Regional population data, plant and operational toxic chemical sins data, regional atmospheric conditions. In this study, the regional population data are mainly provided by the District Public Offices; Factories and operational toxic chemical substances data, mainly by the Environmental incidents specialist team of the northern area survey and statistics; Regional atmospheric conditions refer to data obtained by the climate statistics of the Central Weather Bureau, MOTC. The receiver then organizes the above data into the required parameters. After finishing, quantitative risk assessment was carried out at meteorological temperature of 29.34°C, pressure 1001.62hPa, humidity 75.16%, wind speed of 1.85m/s and atmospheric stability D, and reference was made to the permissible concentration of toxic chemicals, individual risks and social risks pointer. It was found that some factories in industrial areas due to toxic chemicals, respectively, B2(hydrazine), F3-7(hydrazine), F5(formaldehyde), H2(acrylonitrile), K1(acrylonitrile), M3-1(formaldehyde) and M3-2(formaldehyde), In the event of a accidental spill disaster, the scope of the damage will spread beyond the industrial zone, will have very serious consequences for people and the environment around them, if the risk of harm is to reduce, it is necessary to regulate the toxic chemicals that operate these plants and make them less hazardous. The personal and social risk values of Industrial Park sparing the acceptable risk range.
