摘要

本研究對8種消防衣利用儀器假人進行火焰衝擊測試，以了解各種消防衣在模擬高溫閃燃、爆炸等著火環境下，對人員的防護能力。除觀察在火焰衝擊時消防衣外觀的變化及餘燃時間的量測外，再以假人身上的溫度感應器讀出的數值求出灼傷程度與灼傷面積比例，籍以了解各部位皮膚表面所達到的最高溫度與最大熱流量。從實驗結果發現，FTJAP消防衣造成的灼傷程度最嚴重，三級灼傷達70%的面積；而FTUSA消防衣的灼傷程度最小，三級灼傷達10%的面積。由檢驗各消防衣的外觀來分析，則可知如果使用的材料在進行火焰衝擊時，能夠使防護衣仍具有完整的結構，且不產生脆化與收縮，則愈具有防護能力；同時對於消防衣上的零配件也要格外注意，尤其是薄膜與反光條，若此處產生熱收縮，就會減低消防衣的防護能力。

The study determined the protection of firefighter's clothing while the clothing faced flashover and explosion condition. Eight different kinds of firefighter's clothing put on an instrumented manikin under flame engulfment measured the burning degree, burning area ratio and the highest temperature and the average heat flux per body segment through the bum risk calculation of the temperature sensors on the manikin surface. The result showed that while FTJAP was the most serious bum risk with 70% surface area of 3rd degree burning, FTUSA was the only one affected by 10% surface area. The appearance of firefighter's clothing after flame engulfment was also analyzed. The analysis indicated that the more integrity the inner layer of clothing had after exposure, without brittleness and shrinkage, the more protection the clothing was. At the same time, the accessories on the firefighter's clothing were also crucial, especially for membrane and retro-reflective stripes. If they shrink in the exposure of flame, the protection of the clothing would reduce.
