  • In this study, we have assessed the fire risk of Buddhist temples located in Youngdong area by means of fire loads of components. First, we categorized the components into Buddhist temples (Dae-Ung-Jeon, Pal-Sang-Jeon), Sam-Seong-Gak (Chil-Seong-Gak, San-Sin-Gak), a Buddhist temple dormitory (Sim-Geom-Dang, Seol-Seon-Dang), Lu, Il-Ju-Mun and then carried out a field survey. Then, we examined the area of each room, types as well as quantity and dimension of combustibles. The fire loads calculated in this way were 446.96 $kg/m^2$ for Buddhist temples, 331.71 $kg/m^2$ for Sam-Seong-Gak, 164.14 $kg/m^2$ for the Buddhist temple dormitory, 463.91 $kg/m^2$ for Lu and 1042.14 $kg/m^2$ for Il-Ju-Mun, thus showing Il-Ju-Mun with the biggest fire load. We speculate that this is because construction materials were similar in size and quantity to others albeit the area of Il-Ju-Mun is smallest.

  • 본 연구는 건축구조물의 내장재 및 실내장식물 등의 연소 성상 DB를 바탕으로 화재 성상을 예측할 수 있는 기존 모델인 칼슨모델(B.Karlsson) 및 퀸티어리모델(J.G.Quintiere)을 비교, 분석하여 그 절차 및 차이점 등을 분석한 후 국내 가연물 연소성상 DB를 토대로 개구조건 및 건물구조 등을 고려한 화재성상 시뮬레이터 개발을 위한 기초 조사 자료이다. 조사 결과 칼슨모델과 퀸티어리모델의 차이점은 우선 초기 착화영역과 착화의 판단 및 연소면적 등에서 차이가 있었으며 향후 이를 기초로 실험 결과와 대비를 통한 분석을 수행 할 예정이다.

  • 최근 소방법의 경우 초고층구조물을 대상으로 한 성능설계 및 화재영향평가등을 실시할 예정으로 있으며 특히 화재위험성평가등에 대한 대책이 요구되고 있으나 이에 대한 데이터가 부족하며 그 방법론 또한 구축되어 있지못한 상황이다. 따라서 본보는 전보에 이어 화재 위험성평가를 위한 방법론에 대한 일환으로서 위험성예측에 사용하는 화재발생의 상위에 의한 화재규모와 rmm 발생율을 각용도별로 기존의 화재에이터 및 가연물조사결과등으로부터 통계적으로 추정하는 방법에 대하여 검토한 것이다.

  • Domestic sandwich panel buildings are widely used on walls and roofs of factories and warehouse facilities. Factory and warehouse facilities have high fire load and rapid spread of fire due to their use characteristics, leading to large fires. Due to the characteristics of materials, walls and roofs are collapsed, resulting in life damage and property damage. In this regard, this study examined domestic and international standards of sprinkler facilities to prevent ignition of sandwich panel walls. Also, in order to check whether the fire was prevented by installing the head on the wall of the sandwich panel, the fire test was carried out with 10 cm, 60 cm, and 120 cm from the wall along the sprinkler head installation standard of domestic fire safety standards. As a result of the fire test, it was confirmed that the sandwich panel was prevented from igniting when the head of water pressure 0.1 MPa and water quantity K-80 was installed. According to the separation distance, it was impossible to measure the temperature at 10 cm, but at 60 cm, At the maximum temperature of $525^{\circ}C$ and 120 cm, the maximum temperature of the wall of the sandwich panel was measured as $276^{\circ}C$. As a result of the fire test, considering the fire point of 450 degrees Celsius in the fire test of the sandwich panel, the distance from the sandwich panel wall to the combustible is more than 120 cm.

  • In this study, we drew identification techniques of cigarette fires through the cases analyses of the combustion characteristics, the combustion time, the combustion temperature, the combustion test of smoldering materials and the reappearance experiments of cigarette fires. To initiate fires by cigarette fire, the conditions of oxygen supply, combustible materials must be satisfied. On the other hand, fires were not spreaded easily under the insufficient combustion conditions.

  • Purpose: The purpose of the study is to reduce the fire of the same type by analyzing the form which is mainly generated based on the result of the fire investigation through the experiment to reproduce, since the candle fire is repeated every year with the same type. Methods: For the analysis of candle flame, 4 kinds of methods such as acrylic recharge test, FOMEX acrylic recharge test, general combustible recharge test, and natural fire extinguishing test of candle were conducted. Results: It was confirmed that continuous burning is difficult to be achieved without contact of combustible materials around. Conclusion: In order to prevent a candle fire, it is important to check the safety of the surrounding area. It is also considered to introduce safety regulations such as finishing with a fireproof material such as a silver foil at the terminal end.

  • The history of illumination has been much long since the discovery of lamplight caused huge changes in human lives. However, the swift development of the illumination actually started with the invention of a carbon filament lamp by Thomas Edison in 1878. Generally, the illumination tools plays important roles in human lives such as reduction of fatigue, improvement of safety and working efficiency, and the creation of enjoyable atmosphere. But, the illumination tools can be an origin of the fire due to carelessness and lack of management. In this study, the principle and structure of the illumination lamp were dealt with. The possibility of the fire outbreak caused by the incandescent lamp and fluorescent lamp most used in home was investigated. The examples of the fire outbreaks by the incandescent and fluorescent lamps and by the contact between the inflammable materials and the distributing wires were mentioned and demonstrated by the experimental.

  • The purpose of this study on the sheath heater having high occurrence of fires in a small work place because of not having the safety device, was to find out the characteristics required in the field examination of the fires in the courses of investigation. The results of the experiments conducted and reviewed on the basis of the fire cases whose conditions of the ignition possibility were divided into A, E, C and D are as follows: When the sheath heater without safety device is left on the condition of the heat accumulation of which the temperature rapidly rise, and then ignite the inflammables of the surroundings. In such cases, it was characterized that the color change trace appeared even if no short trace was discovered in the power line.
