  • 워터스크린(이하 W/S)에 의한 화재방화시스템은 도로터널에 화재가 발생시, 공간에 수막을 사용하여 구획화하고, 열 연기의 확산을 억제하며 유해 부유입자를 세정함으로서 인간의 안전을 확보 및 구조물의 피해를 극소화 하는 시스템이다. 이 W/S에 의한 구획의 성능을 평가하기 위해, 1/2의 터널 모형에 의한 공간 내 열 성장 파악을 위한 화재 실험을 분석하였고, 그 결과, 천정 근방 온도 및 방사수열량으로서는 발열 속도의 크기, 풍속의 대소에 의하지 않고 약 80%의 저감율을 나타냈다. 또, 발생한 유해 부유입자 농도에 대해서는 약 60%, 화원 성질과 상태로서 발열 속도는 약30%의 W/S에 의한 저감 효과를 나타내었다.

  • This paper is study about establishment with water membrane sprinkler in fire prevention block of special Building. The testing program was directed toward investigating the temperature of fire and adjacent room. The results of fire test indicated that under the test conditions in this study, adjacent room temperature is very low in compare with fire room temperature at operating of water membrane sprinkler. Therefore, if exclusion of smoking can be soluted, substitution of water membrance sprinkler in fire resistance wall of fire prevention block is possible.

  • There are lots of buildings with their deterioration in wholesale markets which have high concentration that can cause big fire due to difficulty of installing fire protection system in fire compartment, absence of safety awareness, access by many and unspecified people. There had been big fire that caused by these kind of fire weakness such as Seomun Market's in 2005 which costed tens of millions dollar, Dongmun Shopping District’s with 7 casualties. Now counter-measure against these fire is urgently needed. This study drew characteristic of current condition of wholesale markets and the one classified by main agent, fire cases and prevention of fire through statistical data. Also, current condition of fire prevention management and actual state were investigated by conducting a survey of person in charge of fire prevention and current practician. As a result, it was shown that securing professionalism of fire prevention, improvement of structural weakness of buildings, obtaining reliability on performance of fire protection system and internal fire education against practician in the market are needed.

  • Tourist hotels are equipped with facilities such as accommodation and restaurants, exercise, recreation. Unspecified guests, visitors and management of tourist hotels are very vulnerable on the casualties and property losses due to fire peril exist. In this study, we analysis that the fire statistics status of tourist hotels from 2001 to 2010. And the 15 cases of a large hotel fire are reviewed. The total number of fires on hotel are consist of a hotel rooms fire(33.2%), a restaurant kitchen fire(11.8%). And the major causes of the fire are an electrical fire (40.8%), a cigarette fire (14.5%) and a hot-work fire (9.2%). In case study, the fire wall defect and combustible materials are major fire loss causes for 10year. Each tourist hotels are needed a development of suitable fire risk management and a field operations. A hotel is required an active fire risk management on a preventive inspection, an education and training, and a preventive maintenance. It is necessary that a fire wall maintenance to prevent of the spread of a fire and a sprinkler installation of whole area to protect fire. And it is very important an emergency response for evacuation of guest, and operate emergency procedures on a fire or emergency situation.

  • Lots of products stocked at a traditional market are made of rubbers, synthetic fibers and plastics which when on fire, emit high heat to easily ignite nearby inflammables. And shops are not divided by fireproof partitions but by combustible curtains, which contributes to a possibility of a conflagration. In this study, danger and weak factors on fire at a traditional market was analyzed. Non-existence of partition between shops and the height of piled inflammables are set as danger factors and change of extinguishing capacity of sprinklers was analyzed using fire dynamics simulator. As a result, it turned out that partitions between shops and high-piled inflammables reduced watering radius of sprinklers and increased the size of fire and distribution of temperature.

  • In the case of a fire accident on a ship or an offshore plant, the design of the bulkhead penetration piece must be verified via a fire test procedure (FTP), as specified by the Maritime Safety Committee (MSC). The purpose of this study is to verify both the numerical analysis results and the design specifications for penetration pieces that could be applied to the A60 class bulkhead division. In this study, the FTP was carried out in accordance with the test procedure prescribed in the MSC regulation. In order to review the fire resistance performance according to the material type, bulkhead penetration pieces for the FTP were made from brass, carbon steel for machine structures (S45C), and austenite stainless steel (SUS316). In addition, spray-type insulation and mechanical fastener-type insulation were applied to investigate the fire resistance performance according to the type of insulation. To verify the heat transfer numerical analysis results for the A60 class bulkhead penetrating piece from this test study, the design specifications of the penetrating piece material and the insulation type applicable to a ship and an offshore plant were identified.

  • This study suggests basic data for fire-resistant compartments to prevent fires from spreading in a traditional markets. As representative combustible goods handled in traditional markets, bedding and bags were chosen. The fire loads could be calculated using the porosity of the materials based on a standard normal distribution. The bedding and bag porosity were 98.7%, and 94.39%, respectively. The the fire load of bedding is $29.9kg/m^2$, and that of bags is $65.61kg/m^2$.

  • Sprinkler system is the most effective fire suppression with high confidence among active fire extinguishing systems. According to the installation of the related system on buildings, more separation area of fire protection can be considered to the fire protection design, and also lower differential pressure (12.5 Pascal) is permitted on lobby of fire escape stairs and emergency elevator (25 Pascal shall be considered for none sprinkler system) with economic factor. More details will be handled on the related studies.
