國內全產業重大職業災害類型中，感電居之第二位，僅次於墜落，而在民國85年至96年之間，國內共發生了636件感電重大職業災害，屬於營造業的有394件(61.9%)，更是高居全產業之第一位。本研究針對其中民國85至91年間之255件營造業感電重大職業災害進行屬性與類別的篩選。篩選方法參照陳正倫(2006) 對於營造業感電職災的研究之編碼系統，屬性分別為年齡、雇用人數、工作經驗、作業別、媒介物、發生原因，類別為危害類型。並根據案例報告書所提供的內容，將每件案例的年齡、雇用人數、工作經驗、作業別、媒介物、發生原因、危害類型歸屬於合理的屬性及類別。之後利用卡方自動互動檢視法找出影響感電職災危害類型分類類別之關鍵屬性，並利用路徑分析法探討各分類類別之罹災者接觸電流的路徑，以制定防災對策。
由分析得知，感電職災發生情境共分類為九種類別，影響資料分類類別(感電危害類型)之關鍵屬性為媒介物、發生原因與作業別，其中影響資料分類類別最關鍵之屬性為媒介物，其次當媒介物為電氣設備、電線、電動手工具、帶電體(間接帶電)時，次關鍵屬性為發生原因；當媒介物為車輛與機械設備時，次關鍵屬性為作業別；當媒介物為高壓電線及電動手工具時，並無其它關鍵屬性會影響資料分類類別。之後針對以上分析結果將其九種類別分別彙整成路徑分析圖，說明各分類類別之感電職災發生的情境、罹災者碰觸電源的各種可能路徑、以及在案例中出現的各種媒介物，接著制定防災對策以阻斷其路徑，以避免類似的職業災害重複發生，或是減輕職業災害之後果。

Electrical shock was the second leading cause of occupational fatality in Taiwan following the falling fatalities. Electrical fatality accounted for 14.6% of all fatal accidents and was the second leading cause of occupational fatality in Taiwan following the fall fatalities. The current study analyzed 255 work-related single fatalities of occupational electrocution from 1996 to 2002. Each fatality was coded in terms of age, company size, experience, tasks, source of injury, and accident cause. CHAID was applied to classify these 255 accidents into 9 accident types based on source of injury, accident cause, and performing task. For each accident type, the path diagrams illustrating the vectors (path) of electricity travelling through human body were identified. The path diagrams can then be used to identify effective barriers within vectors, e.g., more effective safety training, protective equipment and devices, and compliance with established procedures.
