Abstract

Since the Daegu subway fire accident, people's perception of safety has increased, and all materials inside the train have been changed to incombustible materials. However, there is still a lack of development of fire extinguishing systems. Train components are mostly made of steel plates, and therefore it is very difficult to extinguish the train fire by using general fire extinguishing equipment. In this regard, this paper investigated rapid and easy methods of extinguishing the train fire by using compressed air foam systems through full-scale fire tests. To extinguish the fire of train at rescue station, window breakers were used to quickly destroy the train windows, and the compressed air foam system was inserted inside the train. As a result, the train windows were destroyed in 5 seconds, and the 11.88-MW fire was put out in 30 seconds by the compressed air foam discharged from the compressed air foam system inserted inside the train. For the future work, there is a need for further experimental studies to prevent the spread of fire and protect tunnel structures with the use of compressed air foam systems.

대구지하철 화재사고가 발생한 이후에 국민의 안전에 대한 관심이 높아지고 열차 내부의 재료는 불연성 재질로 모두 변경되었지만 소화 설비에 관한 개발은 미비한 상태이다. 열차는 철판 재질로 둘러싸여 화재 시 일반적인 소화설비를 이용하면 소화하기 매우 어렵다. 본 논문은 실물화재 실험을 통하여 정차된 열차 화재를 압축공기포 소화설비를 활용하여 빠르고 손쉽게 소화할 수 있는 방안에 대하여 연구하였다. 구난역에 정차된 열차의 화재를 소화하기 위해서 창문 파괴장치를 이용하여 열차 유리창을 빠르게 파괴하고 압축공기포 소화설비를 열차 내부에 삽입하여 직접적으로 소화할 수 있도록 하였다. 창문 파괴장치를 이용하여 열차 유리창을 5초 만에 파괴하였으며, 압축공기포 소화설비를 열차 내부에 삽입하고 압축공기포를 방사하여 30초 만에 열방출량 11.88 MW 규모 화재를 진압하였다. 압축공기포 소화설비를 이용하여 화재 확산 방지와 터널 구조물 보호가 가능하도록 추가적인 실험 연구가 필요하다.
