高溫作業場所最常被採用以評估勞工墊熱暴露劑量之指標有綜合溫度熱指數（wet bulb globe temperature,WBGT）、修正有效感覺溫度（corrected effective temperature,CET）、及熱應力指數（heat stress index,HSI）等三種。這些指標因其理論依據不同，致使其評估結果不儘相同，但也不致完全背道而馳。本研究之目的再探討以三種指標評估台灣地區高溫作業環境時之相關性，經由實際高溫作業工廠量測資料分別計算出各指標值，並以測點與勞工暴露情形分別討論。所得結果顯示以WBGT與CET間之相關性最高，測點與勞工熱暴露時間加權平均之相關係數 r 值分別為0.82~0.86及0.78~0.89間;其次為WBGT與HSI間之相關性，測點與勞工熱暴露時間加權平均之相關係數 r 值分別平均為0.78與0.75 ;相關性最低者為HSI-與CET。 The heat exposure indexes such as Wet Bulb Globe Temperature (WBGT), Corrected Effective Temperature (CET) and Heat Stess Index (HIS) were usually adapted to evaluate heat exposure dosage of workers in hot workplaces. Due to the various theories in the previous indexes,the assessed results exit certain differences. In general, the difference was minor according to the analysis of experimental data. The objective of the study was to investigate the correlation among three assessed heat exposure indexes for workers in hot workplaces in Taiwan.The values of the previous indexes were exaluated from experimental data in hot workshop,
