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.
