  • Electrical fire in residential, commercial, and industrial areas occupies 40 percent of overall fire accidents as of the year of 1994. The causes of most electrical fires were studied and, based on this investigation, the principle of the early detection or prediction of the electrical fires is developed. The basic principle is to early detect electrical arcs or sparks caused by faulty connections and insulation failures. the structure of the prediction system based on microcontroller technique is presented.

  • It has long been recognized that exposure to fire-induced toxic gases is a fatal hazard confront-ing people in fires. In this study, an indoor fire experiment was conducted in an unoccupied residential building located in An-san city, Kyoung-gi province, and the composition of effluent gases, which include CO, $CO_2$, $O_2$, $SO_2$, NO and $NO_2$, were measured by a gas analyzer. A group of lab rats were exposed to the toxic gases released from fire, and the blood samples of the rats were gathered every 2 minutes. A toxicity evaluation was conducted by analyzing the concentrations of Glucose, AST(GOT), ALT(GPT), CBC Count and CO(carboxy)-Hb in the blood samples. Shown from the analysis is the does-response relationship between the CO concentration that rats were exposed to and the CO-Hb concentration in rat blood.

  • This study explores fire prevention measures for single-person households on the phenomenon of an increase in single-person households due to changes in the family structure due to low birthrate and aging population, full marriage, non-marriage, separation, bereavement, and returning to farming villages, and increased flexibility in the labor market. The factor that affects the fire of single-person households is the residential environment problem at the structural level. In terms of behavior, there is an increase in fire occurrence due to the rearing of companion animals. In order to prevent fires in single-person households, safety regulations without exceptions are needed to improve the residential environment at the structural level. At the behavioral level, it is necessary to expand the prevention and safety guidance of related organizations. In addition, as a measure to prevent fire caused by companion animals, manufacturers of electric ranges should develop safety devices to prevent fires caused by companion animals, such as an automatic power-off device or power supply using a timer. It can also be an important means to create and distribute promotional videos of measures necessary to safely raise companion animals, or to develop and distribute disaster preparedness programs implemented in virtual reality.

  • There are continuous cases of fire expansion due to fire door problems around the world, including the 2010 Shanghai Apartment Fire, the 2017 Grenfell Tower Fire in England, and the 2020 Ul-san Residential and Commercial Complex Fire. In order to prevent such fire damage, the country has strengthened the performance standards of fire doors, and recently, efforts have been made to ensure the best performance of fire doors by introducing a quality recognition system. Securing the performance of fire doors is a very important aspect. However, there is a concern that old fire doors may not function normally in the event of fire due to natural deterioration, corrosion, and damage during the use process, but countermeasures are insufficient. Therefore, from a management perspective, it is very important to maintain fire doors and secure an appropriate replacement time. Therefore, the purpose of this study is to determine whether the fire door has durability to prevent fire spread in the process of use through operation probability analysis and expert surveys, and to propose an appropriate useful life of the fire door.

  • SLIM AU(A plus U-shaped) composite beam had been developed for not only reducing the story height in residential and commercial building, but also saving the cost of floor construction. The structural performance and economic feasibility was sufficiently approved by means of structural experiments and analytical studies. Even though fire resistance of the SLIM AU composite beam was evaluated throughout furnace fire test, the fire performance of the composite beam using finite element analysis is not analysed yet. Therefore the predictions of fire resistance simulations with loading as well as temperature distribution of the composite beam are summarized in this paper.

  • 최근 주거시설의 내장재는 다양화 되어 가고 있지만 안정성 보다는 디자인, 기능성에 치중되어 그에 따른 화재 위험성도 커져가고 있다. 또한 여러 가지 합성수지로 예상치 못한 화재성상을 보이고 있으나 이에 따른 법규는 미비한 실정이다. 따라서 본 연구는 고정가연물중 주거시설에서 많이 사용되어지는 시료를 선정하여 Cone Calorimeter를 이용해 그 연소특성을 알아보았다. 그에 따른 결과로 바닥재는 국내산이 높은 발열량을 보였고 벽지는 국외산이 높은 발열량을 보였다.

  • Heat release characteristics of live fire load are an important parameter for performance oriented fire safety design of a building. While investigations have been carried out on the fire load and its burning behavior in office, residential and commercial buildings and so on, little effort has been paid for the rational treatment of fire load in bookstore. In this report, burning behavior of typical combustible objects in bookstore are studied by measuring heat release rates of bookshelf with book. Based on the results, it has reviewed fire safety when a fire accident occurs on the large bookstore and suggested peak heat release rate per burning surface, fire growth rate, etc of the live fire load required for fire safety design in bookstore.

  • Statistics show that while the number of fires has decreased over the last decade, losses of human life and economic property due to fire have increased. Moreover, the number of large-scale fires that have occurred in recent years has resulted in heightened public anxiety. This study aims to identify a specific period of the year most vulnerable to fire, and fire trends, such as damage of fire to humans, to the economy, and different building types. For this purpose, we analyzed human and economic damages using statistics related to fire from 2007 to 2017 and provided a monthly distribution of fire damages both to humans and to the economy by building type. We also identified the relationship between the human damage and the economy damage, and compared the economic losses per casualty by building type. The human damage in residential buildings occupied the highest portion, whereas the economic damage of industrial buildings represented more than a half of all economic damage due to fire. The economic damage per casualty was shown highest for industrial buildings and has also increased rapidly in recent years.

  • The objective of this research is to study on the formations of thermal stratification in a room in case of several furniture fires such as trashcan, chair, carpet, sofa, mattress and wardrobe as a fire starter in a residential room by performing the experimental studies. The uniformly distributed fire in case of carpet showed that the ignition and the initial growth period were relatively short while the fully developed period was considerably long. The concentrated fires such as the mattress and wardrobe showed that the ignitions and the initial growth periods were relatively long. When fire spread to only one direction, like the case for the trashcan with a regular shape, there was one peak of temperature profile, and for the irregular shaped furniture such as chair, sofa, mattress and wardrobe, there were two or more peaks. The interface heights for the furniture fires were around 1(m) mataining constant state. However, at the time of the maximum temperature, the interface height was lowered to 0.25(m)-0.75(m) from the floor

  • 현 화재 감식 및 조사에서는 일반적으로 화재 조사관의 경험이나 지식으로 판단하는 사례가 있다. 그러나 PL법 및 실화책임법에 따라 국내에서도 과학적 화재조사방법론이 필요시되고 있으며 이에 따라 본 연구에서는 과학적 화재감식 및 화재조사방법론의 일환으로 FDS를 이용한 화재조사매뉴얼의 필요성에 대해서 조사하였다. 그러나 현재 FDS를 화재조사 및 감식에 무분별하게 이용하기에는 어려움이 있으며 이를 활용하기 위한 기초적 화재데이터의 수집이 필요하다고 판단된다.
