  • Identification of the exact cause of a building fire is generally difficult, because the source and initially ignited objects are often severely damaged or even lost during the early stages of the fire. We made an experimental attempt to reasonably estimate the burning during the very early stages of a fire, and identify its source and causes. The case we studied was an apartment fire, which occurred in Tokyo, in July 2002. The fire was extinguished just after flashover, and the on-site investigations suggested the fire started from the TV and TV stand, which had been damaged so severely that it was difficult to conclude that the TV was the ultimate cause of the fire, simply from the on-site investigation. We conducted a series of burn tests using a TV and other products identical to those actually used in the apartment. Tests were set-up and procedures were carefully studied to recreate the conditions of the articles that remained, and of the room itself. The tests demonstrated that the conditions in the apartment could be recreated only when the fire started inside the TV and came into close contact with dresser.

  • Recently, the spread of ESS in Korea has increased and a fire accident has also occurred. By July 2018, there were a total of 7 cases. All 7 cases were ESS systems consisting of lithium-ion batteries and were burned down. Both the automatic fire extinguisher and the fire department were not able to digest. In this paper, the characteristics of ESS fire are analyzed based on recent ESS fire situation and field investigation, and the cause of fire is divided into environmental, electrical and thermal factors. As a result, it was found that the ESS fire was correlated with the installation environment of the system. In the domestic and overseas lithium ion battery test standard and ESS facility standard survey, the trends and differences of domestic and overseas facilities standards were identified. Based on the fire status and field investigationy, and domestic and overseas facility standard survey, measures were suggested to prevent and prevent the spread of fire in ESS fire.

  • 한국화재보험협회는 매년 특수건물에 대한 화재를 조사하여 손해보험회사, 소방방재청, 특수건물 관계자 및 관련기관에 제공하고 있다. 2005년도 화재조사 분석은 특수건물 19,220건 중 화재 또는 인명피해가 발생한 514건을 대상으로 하였는데, 293억 원의 재산피해가 발생 하였으며 화재발생률은 2004년도의 2.76%보다 0.09%포인트 감소한 2.67%로 나타났다. 또한 국내 손해보험업계의 화재보험에 대한 손해율(재산종합보험 손해율 제외)은 2004회계연도(2004.4.1-2005.3.31) 기준으로 특수건물 51.7%, 비특수건물은 52.8%로 나타났다. 본 고에서는 최근 특수건물의 화재경향을 살펴보고, 2005년도 화재분석 내용을 분석하여 화재예방과 피해절감 대책을 위한 자료를 제공하고자 한다.

  • 최근 건축물 화재에 있어서 가장 큰 문제는 화재지점의 연소보다 연소 확대를 통한 인접건축물의 화재로 전파되는 2차적 피해를 들 수 있다. 또한 이러한 화재 피해의 경우 화재원인을 명확하게 결정내리기 힘들기 때문에 화재 조사 분야에서도 큰 어려움이 있다. 이러한 현실에서 호서대학교에서는 2009년 도시화재의 물리적 연소성상 예측모델을 위한 실제 실험을 대상으로 CFD 중 FDS를 이용하여 이를 해석하고 이를 통한 화재조사분야에서 활용범위와 신뢰도를 제시하고자 한다.

  • Currently, there are various institutions performing fire investigation and identification, such as fire stations and police stations as well as institutes related to fire safety, etc. And the manpower working at the institutions reaches a large number of persons. But there is no objective index on the expertise of the persons. In this paper, we suggested the examination criteria through job analysis and the enforcement method of the exam system. And we developed suitable exam subjects and exam content specifications for qualification of fire identification and estimation that investigate a fire cause, combustion, escape circumstances and fire facilities at the scene of a fire, survey the fire damage and analysis fire cause, etc. It will increase the public trust to develop national technical qualification items of the fire identification and estimation engineer.

  • As lithium batteries have been used for car navigation systems and as the second battery for black boxes, lithium battery-related car fires have often occurred. In the case a lithium battery is the fire origin, a fire investigation technique has not been established to determine if a battery ignites or whether the lithium battery is damaged by fire. This study introduced car fire cases related to lithium batteries, analyzed the causes of a fire of a lithium battery, and proposed fire investigation techniques to objectively determine if a lithium battery ignites or whether a lithium battery is damaged by fire after external ignition.
