Abstract

In this study, applicability of compressed air form (CAF) fire water was verified in a bid to use the undersea effluent as fire water. Foam collector was fabricated in accordance with KS B ISO 7203-1 (Specification for low expansion foam concentrates for top application to water-immiscible liquids) and the test was conducted using fresh water as fire water for 19 times and using seawater as fire water 15 times that totaled 34 times. Foam reduction time was 237.73 seconds on average with fresh water and 215.60 seconds with seawater, which proved the applicability of CAF fire water using seawater. Besides, window breaker was fabricated to directly extinguish the fire in train and a full-scale fire test was conducted three times. At the final 3rd test, window glass was broken in 2 seconds to make the hole for fire extinguishing and suppressed the fire in 3 seconds using CAF fire extinguisher.

본 연구에서는 해저터널 내부에서 발생하는 해저유출수를 소화용수로 사용하기 위해 서, 압축공기포(CAF) 소화설비의 소화용수 적용성을 확인하였다. KS B ISO 7203-1 (비수용성 액체에 적용되는 상부주입식 저팽창 포원액 사양) 규격에 따라 포수집기를 제작하였으며, 소화용수를 담수로 19회, 해수로 15회로 총 34회 실험을 하였다. 포 환원 시간은 담수는 평균 237.73초, 해수는 평균 215.60초로 측정되어, 해수의 압축공기포(CAF) 소화용수 적용성을 확인하였다. 아울러, 열차 내 화재를 직접적으로 소화할 수 있도록 창문 파괴장치를 제작하고, 3차례 실물화재 실험을 수행하였다. 마지막 3차 실험에서는 2초만에 유리를 파괴하고 소화활동을 할 수 있는 구멍을 만 들었으며, 이동식 압축공기포(CAF) 소화기를 사용하여 3초 만에 화재를 진압하였다.
