鑒於消防人員殉職案件頻繁，本研究針對消防機關於災害現場所遭遇之問題進行盤點，建立其社會脆弱性指標，並歸納成災害現場消防機關社會脆弱性模型，以描述消防機關於災害現場之困境。本研究透過文獻探討分析社會脆弱性、消防機關運作及災害現場消防機關所遭遇問題。本研究採KJ法進行資料收集，並輔以修正式德爾菲法建構災害現場消防機關社會脆弱性之5項構面與19項指標。5項構面包括「勤務規劃管理」、「職能管理」、「指揮及管制管理」、「資源及資訊管理」及「裝備器材選用及流程管理」；19項指標則涵蓋派遣、人力、指揮、通訊、資訊、佈署、裝備與後勤等關鍵領域。透過內容分析法，進一步建構消防機關社會脆弱性模型，並進行內容說明。 本研究得出三點結論：(1) 消防機關社會脆弱性構面與指標呈現趨勢，可作為降低脆弱性之參考；(2) 其社會脆弱性係由災害現場多階層應變互動所致；(3) 降低災害現場消防機關社會脆弱性需採取多策略並推動長期計畫，以確保有效執行。

To enhance firefighter safety at disaster scenes, this study identifies challenges faced by fire agencies, which contribute to their social vulnerability. A literature review was conducted to examine social vulnerability, fire agency operations, and disaster scene challenges. Using the KJ method for data collection and a modified Delphi method, this study establishes five dimensions and nineteen indicators of social vulnerability for fire agencies at disaster sites. The five dimensions include "Duty Planning and Management," "Competency Management," "Command and Control Management," "Resource and Information Management," and "Equipment Selection and Process Management." The nineteen indicators cover key aspects such as dispatch, personnel management, command structure, communication, deployment, logistics, and equipment suitability. Content analysis was employed to develop a comprehensive social vulnerability model for fire agencies at disaster sites. This study concludes that: (1) The identified dimensions and indicators exhibit trends that can guide future mitigation strategies; (2) Fire agency social vulnerability stems from multi-level interactions at disaster scenes; and (3) Reducing social vulnerability for fire agencies at disaster sites requires multi-strategy, long-term planning for effective implementation.
