摘要

熱應力是廣為人知引起的熱疾病傷害的工業安全衛生危害，對於必須穿著膠囊式防護衣Encapsulating Protective Clothing(EPC)工作的工作者更是如此。如工作於建築、精鍊、石棉清除、化學實驗室、有害毒物清除場所活動或是在精密鑄造廠中，都必須穿著EPC防護衣執行任務，容易加深熱環境之熱對身體傷害的影響，影響工作者的健康，也影響工作生產力。
針對穿戴防護衣工作者的熱應力暴露監控仍局限於一般的大環境（周圍環境）評估方法，此方法如果低估熱應力，工作者容易導致增加熱應力疾病傷害風險。如果高估熱應力而進行控制措施，也許會導致生產力損失。必須即時監控評估工作者防護衣內部小環境氣候和工作者生理狀況的方法來評估熱應力。並探討身穿防護衣對於靈敏度的影響。
本研究第一目的為整合一具即時個人監控器，用溫、溼度感應器評估EPC內部小環境氣候狀況，心搏率、耳溫和皮膚溫評估工作者生理狀況狀況。並以連續回報方式監控。第二目的為比較徒手、穿戴手套、穿戴手套與防護衣三種不同狀況下，進行木栓板實驗的完成時間對靈敏度影響。
整合後個人監控器可以用來監控工作者身穿EPC內部，以溫溼度感應元件SHT15評估小環境氣候及用皮膚溫度溫度感應晶片LM-92、耳溫溫度感應晶片MLX90614、心搏率量測手錶POLAR S810評估生理狀況，透過Borland C++ Builder 6.0軟體撰寫之程式介面將數據獨立顯示出來。徒手完成時間(45.97±5.87秒)和穿戴手套(127.36 ±47.96秒)和防護衣完成時間(129.44±48.76秒)有明顯的差異，而徒手有較佳的靈敏度。

Heat stress is a well-known industrial safety hazard that causes heat injury. It is more hazardous to those who have to wear Encapsulating Protective Clothing (EPC) during work. People doing this kind of jobs such as construction、refinement、asbestos purgation、chemical experiment、poison purgation or exact commercial foundry, have to wear Encapsulating Protective Clothing(EPC) while performing their tasks. Wearing EPC is easier to increase the heat from environment to human body, then, affect the worker’s health and productivity.
The heat stress monitor of the workers who don’t wear EPC is still limited to normal environment condition. If the heat stress is being underestimated, the workers would easily increase the risk of getting hurt by heat stress. If being overestimated, the control measures would probably lead to the reduction of productivity. We have to monitor the heat stress inside of microenvironment worn by workers and their physiology condition immediately and discuss the effect of wearing EPC to the dexterity.
The first research goal is to integrate a personal monitor. We can measure the microenvironment inside the EPC by using the temperature and wet sensors、heartbeat rate、tympanic thermometry and thermography. The second research goal is to compare the length of finishing time of pegboard tasks under three different situations “barehanded”, “gloved” and “gloved EPC” and see how it affects the dexterity.
The integrated personal monitor can be used to monitor the inside of EPC worn by workers, using SHT15 to estimate the climate of microenvironment, LM-92 to estimate the skin temperature、tympanic thermometry sensors-MLX90614 to estimate the ear temperature、POLAR S810 to estimate the physiology situation.The data will be shown immediately through a Borland C++ Builder 6.0 system. There is a big difference between the barehanded (45.97±5.87 s), gloved hand (127.36±47.96 s) and EPC worn (129.44±48.76’s) conditions. Furthermore, the dexterity of the bare hand is better than the other conditions.
