  • Every crew are in great peril that they should put out a fire on board in person due to a property of ship isolated. Accordingly, it is essential to verify whether the fire-fighter's outfits and fire-fighting scenarios in accordance with present regulations are safe and effective actually. As a result of comparison between shore fire-fighter's outfits and fire-fighting scenarios and those on ship and statistics calculation of the place and frequency of the fire of actual ship, present limitations of fire suppression system and fire-fighter's outfits were proved. In addition, derive the distance to the place on ship that has highest frequency of fire occurrence from examining actual ship's drawings according to their description and size. Finally from experiments in more experimental groups by changing numbers of actual fire-fighters and environment and conduction of survey of a number of crew in active service on ship, the most effective fire-fighter's outfits system and fire-fighting scenarios will be derived.

  • 4족 보행 로봇을 투입하기 위해서는 로봇을 운반할 수 있는 차량이 필요하며 특히 본 연구에서는 군용 작전 지휘 차량을 벤치 마킹하여 화재 진압용 TCMV(Tactical Command Monitoring Vehicle)를 개발하고자 하였다. TCMV를 통해 4족보행 로봇이 화재 현장에 진압할 수 있도록 시나리오를 개발하고 있으며, 아울러 TCMV의 요구사양을 정의 하기 위하여 소방관을 중심으로 의견을 수렴하여 화재 진압의 전략을 개발하고 있다. 추후 TCMV에 적합한 차량과 각종 모니터링 시스템을 구축해 4족 보행 로봇의 화재 진압 기능과 구조 기능을 극대화 하며 새로운 화재 진압 전술이 될 것으로 기대된다.

  • NFPA-805 불확실도 분석 요건에 따른 경수형 원전 스위치기어실 모터제어반의 화재시나리오에 대한 입력변수 불확실도 평가를 수행하였고 이를 통해 화재모델링의 불확실도 평가방안을 제시하였다. 화재모델링은 FDS5를, 불확실도분석은 MOSAIQUE를 사용하였고 Wilks 방법에 근거하여 93회의 latin hypercupe 샘플링을 수행하였다. 스위치기어실 케이블의 최소 평균손상시간은 212초로 예측되어 화재발생시 스위치기어실의 화재진압은 약 4분 이내에 이루어져야 하는 것으로 확인되었다.

  • 현대사회가 급속한 발전을 이룩하면서 화재의 발생은 증가추세에 있다. 화재의 예방과 진압장비의 개발을 위해서는 실내화재현상에 대한 연구와 이해가 필요하다. 대부분의 실내화재 관련 현상에 대하여서는 많은 연구가 이루어졌고, 이러한 연구를 바탕으로 컴퓨터 시뮬레이션과 같은 화재 현상의 예측기법을 발전 시켜왔으며, 거의 실제에 가깝게 발전하고 있으나, 아직까지도 규명이 확연히 되지 않고 있는 부분은 창유리의 파괴현상이다. 본 연구는 구획화재시 창유리의 파괴현상을 실제에 근접한 시나리오를 설정한 후 실험을 통해 고찰하고자한다. 또한 파괴시간 예측 프로그램인 BREAKl의 분석 결과와 실험치의 비교도 아울러 실시하여 그 적용성을 판단해보자 한다.

  • Large scale fire tests were conducted to develop water mist nozzles as a component of fixed water- based fire fighting systems for Ro-Ro spaces and special category spaces. Fire scenarios for this system consist of two cases which are for cargo fire in a simulated truck and for passenger vehicle fire, and each case has 3 different tests according to the position between fixed water mist nozzles and fire source. Every experiment proceeded for 30 minutes and acceptance criteria were based on gas temperature, fuel package's damage and ignition of targets. This study primarily dealt with the experimental results of cargo fire and focused on fire suppression capability in accordance with discharge pressure, flow rate and flow characteristics like swirl and penetration of the developed water mist nozzles. It appeared that low pressure water mist nozzles with about 40 L/min were able to control fire occurred in Ro-Ro spaces.

  • Purpose: This experimental study was conducted to find out whether a water-mist fire suppression system can be applied to C.E.P., a representative combustible material of a rack storage. Method: First, it was confirmed whether the water-mist fire-extinguishing system used in this experiment was capable of extinguishing oil fires. After that, the C.E.P. boxes were loaded in the same small space as used in the oil fire experiment, and then the experiment was conducted on three scenarios; door opening, door closing, and door closing and increasing the internal load. The scenario was set considering the opening and space size conditions, which are important factors for the water-mist fire suppression. Result: Oil fire suppression tests have shown that fires are well extinguished in both the door open and closed conditions. In case of a fire of C.E.P. boxes in the same space condition as an oil fire, the fire was not extinguished in the door open condition. Fires were extinguished in the case with the door closed condition, but the afterglow was confirmed. Conclusion: In the oil fire suppression test, a water-mist fire suppression system extinguished a fire in both the door open and closed conditions. However, for the C.E.P fire, it was possible to extinguish only under the door closed condition, and there was a possibility of re-ignition.

  • Fire suppression tests are carried out for a train car using water mist systems. Three kinds of fire scenario applied to the real-scale train car are a surface fire representing car combustibles, a oil pool fire pretending an oil spill and a blocked fire for evaluation of space-cooling capacity. Five fixedpressure water mist systems and one self-contained water mist system with nitrogen gas are used for fire suppression experiments. Almost water mist systems can extinguish effectively train car fires, and fire-control capability of the system is seen due to the space cooling.

  • Purpose: This study aimed to develop a cardiopulmonary resuscitation training program for firefighters (FD-CPR) to help improve the survival rate after cardiac arrest on the fireground. Methods: The FD-CPR was developed following 3 steps of the FD-CPR instructional design based on the behaviorism theory. The content of the program was validated by a group of 7 experts using the contents validity index (CVI) and through a pilot-test. Results: A scenario consisting of 7 procedures, and a skill performance evaluation tool consisting of 16 questions were developed. The evaluation tool average score for the difficulty test was 41.16% (even) and that for the discrimination test was 0.32 (high). Subsequently, an 80 min training program was developed. As verified by the 7 experts through the CVI, it was as high as 1.0. Conclusion: The FD-CPR developed domestically for the first time in this study was effective in enhancing the CPR performance skills of the firefighters. If FD-CPR is added to the curriculum at the Fire Service Academy educational course for the new firefighters, the CPR performance skills could be maintained. Furthermore, the program can facilitate a better survival rate for colleagues having cardiac arrest on the field.
