中文摘要 | 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 efftivetemperature,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 的在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CRT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WBCT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值分別不均為0.78與0.75;相關性最 低者為HSI與CET。 |
英文摘要 | The heat exposure indexes such as Wet Bulb Globe Temperature (WBGT), Corrected Effective Temperature (CET) and Heat Stess Index (HSI) 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 theanalysis 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 ofthe previous indexes were exaluated from experimental data in hot workshop, and the correlationamong the indexes at position of hot workplace and heat exposure time- weighting average (HETWA) of labors was examined. Obviously, there was a better correlation between WBGT andCET than the others. The linear correlation coefficients (r-values) between WBGT and CETwere 0.82-0.86 (position of hot workplace) and 0.78-0.89 (HETWA of workers), respectively. Onthe other hand, the correlation between HSI and WBGT, and the average r-value of position ofhot workplace and HETWA of workers were 0.78 and 0.75, respectively. However, the corrieation of HSI and CET gives a slightly worse result. |
