Abstract

This experimental study shows the thermal characteristics of the fire fighter's waterproof clothing exposed to the radiation heat. From the test results, the surface temperature of the fire fighter's waterproof clothing exposed to the radiation with the passage of time sharply increased as the exposed-distance became closer. Also as the radiant heat flux increased, the surface temperature is higher and the time reaching steady state is sharply shorter. As the exposed-distance become more distant, the surface temperature of the fire fighter's waterproof clothing decreased and the difference of temperature between the front side and the back side of the clothing decreased as well. Besides, the radiant heat flux increased, the safety exposed-distance increased. Therefore it is necessary that fire fighter have to work keeping a fixed safe distance from the radiant heat source.

본 연구에서는 복사열에 노출된 소방용 방수복의 열적 특성에 대한 실험을 수행하였다. 실험결과 소방용 방수복의 노출시간에 따른 표면의 온도상승은 노출거리가 가까울수록 급격히 일어났다. 또한 복사열유속이 클수록 표면의 온도가 높으며, 정상상태 도달시간은 짧게 나타났다. 소방용 방수복의 노출거리가 멀어질수록 표면의 온도는 급격히 감소하며, 전면과 후면의 온도차도 감소하였다. 복사열유속이 증가할수록 안전노출거리가 증가하였다. 따라서 소방대원의 안전을 위해서는 복사열원으로부터 일정거리이상 떨어져 작업하여야 할 것으로 사료된다.
