熱應力(Heat stress)是廣為人知的安全、健康危害,對於在高溫環境中必須穿著膠囊式防護衣(Encapsulating Protective Clothing , EPC)之工作者更是如此。工作者穿著EPC進行工作時,體熱與汗水會在皮膚和EPC之間形成一個小環境氣候,而目前穿著EPC工作者之熱暴露監控,仍侷限在外在環境(大環境)之評估方法。 本研究利用即時熱應力個人監控器、Polar心率錶、電子體重計、及主觀不舒適量表,採樣6名男性於外在環境溫度(21℃或29℃)、是否穿著EPC(未穿著或穿著)、工作負荷(中度負荷或重度負荷)及重複測試(第1次或第2次)之作業情況組合,探討熱應力對皮膚溫度、耳溫、小環境溫度、心搏率、出汗率及主觀不舒適度之影響,並比較大環境與小環境之差異。 研究結果顯示,「外在環境溫度」、「是否穿著防護衣」對受測者之皮膚溫度、耳溫、心搏率、主觀不舒適度及小環境溫度皆有顯著影響。「工作負荷」方面只有對受測者之心搏率有顯著影響。「重複測試」方面只有對受測者之耳溫和主觀不舒適度有顯著影響。大環境溫度與小環境溫度,兩者之間有顯著差異,小環境溫度顯著高於大環境溫度。
Heat stress is well-known safety and health hazards, especially for workers wearing Encapsulating Protective Clothing (EPC) in high temperature environment. The body heat and sweat would form a micro-environment climate between the skin and EPC during EPC works. Currentenly, the monitoring of thermal exposure is still limited to the assessment of the external environment. This research used personal heat stress monitor, Polar-rs800cx heart rate monitor, electronic scales, and subjective discomfort scale to explore the skin temperature, tympanic temperature, micro-environment temperature, heart rate, sweat rate, and subjective discomfort of six males under different external environment temperature (21℃ or 29℃), EPC wearing condition (not worn or worn), workload (moderate load or heavy load), and repetition (1st or 2nd). This study also compare the differences between the external and micro environments. The results showed that the “external environment temperature” and “EPC wearing condition” have significant effects on skin temperature, tympanic temperature, heart rate, subjective discomfort, and micro-environment temperature. “Workload” showed significant effect on heart rate. “Repetition” showed significant effect on tympanic temperature and subjective discomfort. Significant differences between the external and micro environments were found in this study. The micro-environment temperatures were significantly higher than the external environment temperatures.
