요약
본 연구는 침윤소화약제의 소화성능평가를 위해 실규모 소화실험을 수행하였다. 실험은 '수동식소화기의 형식승인 및 검정기술기준'에 명시되어 있는 A급 소화실험 방법에 따라 진행하였으며, 목재 외에도 목분과 왕겨를 대상으로 실험을 진행하였다. 소화용수는 물과 국내에서 사용되고 있는 3종의 침윤소화약제를 사용하여 성능평가 실험을 진행함으로써 물과 침윤소화약제의 명확한 변별력을 확인하고자 하였다. 실험 결과 물의 경우에서 내부 온도의 유지시간이 길게 유지되고 침윤소화약제의 경우 빠른 온도 하강을 나타냄을 확인하였으며, 시간에 따른 온도분포를 통해 소화능력의 변별력을 확인하였다. 본 실험 결과를 바탕으로 추후 최적화 침윤소화약제 성능평가 방법을 제시하는데 기초자료로 활용할 수 있을 것으로 판단된다.
Abstract
Real scale fire tests was carried out for extinguishing performance evaluation of the wetting agent. The experiment was conducted in accordance with a Class A fire extinguishing test methods specified in the 'Type Approval of the Manual System Fire Extinguisher and Technical Standards of Test'. In addition, the subjects of this experiment were the wood flour and rice husk. Fire-fighting water, the three kinds of wetting agents used in the country and this study was used, was undertaken to determine a clear discrimination of the water and wetting agent. In the experimental results, it was confirmed that the internal temperature is maintained long time in the case of water. The internal temperature were rapidly lowered in the experiment of wetting agents. Therefore, the discrimination of extinguishing ability was confirmed by the temperature distribution in accordance with time. Based on the results of this experiment, this study is expected to be used as a underlying material on presenting a method of optimized performance evaluation of wetting extinguishing agent.
Key Words: Deep-seated fire, Wetting agent, Real scale fire test, Extinguishing performance
