電弧閃光灼傷危害係從事配電箱（盤）作業時，僅次於感電危害之電氣災害，但國內目前欠缺有關電弧閃光灼傷危害之相關文獻及技術資料，且未有相關國家標準，而一般事業單位或電機技師等大都也沒有實施相關配電箱（盤）之電弧閃光灼傷危害分析。本文首先探討IEEE 1584標準之電弧閃光灼傷危害分析方法，並彙整有關NFPA-70E有關電弧閃光個人防護裝備之選用及危險警告標示等規定，最後以供電系統包含22.8kV、380V及220V等三個電壓等級之某電子工廠，建立進行配電箱（盤）電弧閃光灼傷危害分析之實際範例，以提供電氣配線設計者、電業、半導體業、石化業、鋼鐵業等電力用戶事業單位進行電弧閃光灼傷危害評估與計算參採，及勞動檢查單位檢查參考，以降低配電箱（盤）電氣作業之電弧閃光灼傷危害事故。

Aside from electric shocks, burns from electric arc flash are the most common injury suffered by electricians operating on panelboards. However, Taiwan is lacking in standards and technical documents on electric arc flash burns. Therefore, most of the companies or electric technicians have not performed the hazard analysis caused by electric arc flash from panelboards. We discuss the IEEE 1584 analysis methods of burns from electric arc flash, and the NFPA 70E selection of personal protective equipment and the warning label of hazard. Finally, to establish an example of panelboard arc flash analysis, the IEEE 1584 base program is applied to an electronic plant which the electric system including 22.8kV, 380V and 220V.
