隨著國內辦公大樓數量逐年攀升，與其相關的安全管理問題也漸漸受到社會各界的重視。哪些是辦公大樓安全管理的危險因子？究竟這些危險因子中最需各安全管理單位重視與改進的高風險因子在哪裡？改善對策為何？ 本研究以行政院新莊聯合辦公大樓為對象，探討其在安全管理工作上所面臨的作業風險。先以文獻探討法、觀察法、問卷調查找出安全防護危險因子，再利用作業風險管理整合軟體 (ORMIT)評估並排列其風險優先順序，進而找出可能的改善對策。最後再經專家學者的訪談意見找出具體改善方法。 結果顯示，經本研究選定風險控制方法後，平均風險等級由原來的高度H-7級，在預期部分可降至低度L-15級風險，而模擬實際執行後也可降至低度L-14級風險，顯示降低風險等級之成效的不錯。 本研究具體提出降低辦公大樓安全管理風險之對策，包括以下數項：1.定期保養、維護，以保持設備運作正常。2.設立檢修制度。3.加強監視力量，輔以保全巡邏。4.即時更新設備，減少意外中斷。5.強化人員教育訓練。

With the number of domestic office building increasing year by year, the issues of security management have been gradually emphasized by community. Where are the hazards of office building security management? Where are the high-risk areas that the hazards were emphasized and improved by every unit of security management? What is the improvement solution? This paper focuses on the joint office buiding of Executive Yuan in Xinzhuang to probe the operational risk of security management. First, we find the hazards on security by paper review, observation and questionnaire survey. In application of the ORMIT(Operational Risk Management Integration Tools) to current study is able to calculate the risk and to fine the possible improvement solution. Finally, through interviews with experts and scholars, we are to identify concrete ways to improve office building security. After risk control method being selected, we find, the average risk level of the original H-7 (high risk level) can be reduced to L-15 low level as expected. Following the same analytical procedures, the risk level of simulated outcome of actual execution can also be reduced to L-14 low level risk. This means that the effectiveness of risk reduction is excellent. According to the outcomes of this study, we offer some solutions to reduce the risk of office building security management as follows: (1) Regular maintenance to keep the equipment functioning properly. (2)Establish maintenance system, and perform reliably. (3)Strengthen the surveillance force, and patrol by security guard. (4) update the equipment to deal with modern technology crime (5)Strengthen the personnel education and training.
