Abstract

In this study, applicability of compressed air form (CAF) fire water was verified in abid to use the undersea effluent as fire water. Foam collector was fabricated inaccordance with KS B ISO 7203-1 (Specification for low expansion foam concentratesfor top application to water-immiscible liquids) and the test was conducted using freshwater as fire water for 19 times and using seawater as fire water 15 times that totaled34 times. Foam reduction time was 237.73 seconds on average with fresh water and215.60 seconds with seawater, which proved the applicability of CAF fire water usingseawater. Besides, window breaker was fabricated to directly extinguish the fire intrain and a full-scale fire test was conducted three times. At the final 3rd test, windowglass was broken in 2 seconds to make the hole for fire extinguishing and suppressedthe fire in 3 seconds using CAF fire extinguisher.
