  • Recently, along with the continuous increase in the supply of electric vehicles, electric vehicle fire accidents are also showing a rapidly increasing trend. Electric vehicle fires last for a long time compared to fires in internal combustion engine vehicles and have problems with the risk of secondary explosions and the generation of large amounts of smoke. In particular, electric vehicle fires in underground roads, which are semi-enclosed spaces, may amplify the problems of existing electric vehicle fires. On the other hand, there are no domestic response guidelines for electric vehicle fires occurring inside underground roads. Therefore, an awareness of fire accidents was confirmed through a survey of the general public, and electric vehicle fire characteristics and primary considerations were derived from stakeholders related to electric vehicle fires in underpasses. Through this, the guidelines for responding to electric vehicle fires on underground roads were established.

  • The time to ignition, heat release rate characteristics, and carbon monoxide yield of fiber reinforced and sandwich phenol resin were investigated with cone calorimeter. The fire characteristics of unsaturated polyester, mostly being applied to the existing passenger train, and phenolic resin were compared. DSC & TGA was used to monitor the degree of thermal decomposition and weight loss for the phenolic resin. According to the cone calorimeter data, the time to ignition was shorter, heat release rate, and CO yield was higher as the external heat flux increased. Under the same heat flux, the time to ignition of sandwich type phenolic resin was shorter than that of laminated. The result of comparison between unsaturated polyester and phenolic resin was that phenolic resin was shown to have better fire resistance than unsaturated polyester.

  • 현재 국내에서 발생하는 화재의 대부분은 밀집한 건물에 발생하는 화재이다. 이러한 건물화재의 특징은 초기진화에 실패할 경우 인접한 건물로 화재가 번져 대형 화재로 이어지며, 이로 인한 피해도 급증하게 된다. 또한 소방차 출동 시 도로여건이나 주 정차 차량 등 다양한 진입 장애물 등으로 화재지역으로 신속한 접근이 어려운 경우가 많다. 따라서 실효적 화재 진화 성능을 가진 방수시스템을 탑재한 소형화된 미니 소방차를 개발하고자 하며 아울러 고지대나 산림 화재의 초기 대응을 위해 험로(산악지형)에서도 주행이 가능한 ATV(All Terrain Vehicle)를 적용하고자 한다.
