1960년대까지는 저팽창단백포가 유류화재의 진압에 주로 사용되었으니 불소화합물 계면활성제로부터 유출된 합성 AFFF를 개발하면서 해수로도 이의 사용이 가능하고 지역 및 유출화재 예방에서 AFFF 특유의 초기진압효과 및 대형화재를 방지한다는 장점 때문에 널리 사용되고 있으며, 석유화학산업의 저장탱크지역 및 공정지역에서 AFFF와 FPF가 주로 사용되며 부두시설(Oilrig, Marine Tanker, 해상 / 해변터미널)에는 AFFF의 사용이 지배적이다. 현재 사용되고 있는 foam으로는 단백포(Protein: PF), 불화단백포(Fluoroprotein: FPF), 막형성 불화단백포(Film Forming Fluoroprotein Foam: FFFP), 고팽창폼(High Expansion Foam), 수성막 형성폼(Aqueous Film Foaming Foam: AFFF), 알콜폼(Alcohol Resistant Foam: ATD) 등이 있으니 본고에서는 AFFF 중심으로 소개한다.

The reduced scale fire test provides basic data but it is not enough to analysis real fire problem directly because there is no exact analogy theory between a real fire and the reduced scale model. Therefore we have developed the large scale calorimeter in order to the real scale fire test. This advanced large scale calorimeter used for physical properties such as a heat release rate, based upon consumption of $O_2$ method. Using this large scale calorimeter, we cameo out the real scale vehicle fire test in order to evaluation for heat release rate. We obtained the calculated result for HRR $2.3{\sim}3.4\;MW$ and this result is very similar to the PIARC candidate HRR. It is approve that this facility has the reliability and it is capable of applying to the advance fire research in the future.

Purpose: The number of Cold Storages at home and abroad is on the rise, fires in large Cold Storages have recently occurred. As fires continue to occur and property damage is on the rise every year, the importance of preventing fires in large Cold Storage is growing. Method: Real Cold Storages were investigated on-site and fire cases were analyzed to derive and analyze fire risk, and the ORS, which is emerging as an adaptive fire prevention technology of Cold Storage, was investigated through FDS. Result: oxygen concentration 21, 15.7% and 17.7, 16.7% were analyzed through FDS, and flashover was reached within 3~4 minutes from 21, 17.7, 16.7%, but if oxygen concentration was lowered to 15.7%, it didn't ignite for 13 minutes. Conclusion: This study understood the concept and general part of the ORS, modeled the freezer through FDS, and analyzed the oxygen concentration to analyze the fire protection adaptability of the ORS. In the future, it is expected that large-scale empirical experiments and related regulations will be prepared to provide solutions for fire prevention in Cold Storages in blind spots of fire.

최근 들어 산업설비 및 건축물의 대형화, 다 기능화 추세가 두드러지게 나타나고 있는 가운데 화재발생으로 인한 인명 및 재산상의 피해규모가 비례적으로 증가하고 있다. 이에 화재의 근원적 원인과 발생 가능성을 미연에 방지하는 방화ㆍ방폭 기술의 개발이 무엇보다도 중요해지고 있다. 또한 화재예방이 불가능하였을 경우 신속한 화재감지를 통해 화재진압에 나서는 것과 화재특성을 분석하여 화재를 방지하는 것 역시 중요해지고 있다. (중략)

1993년 5월 10일 태국 Kader공업(주)에서 큰 화재가 발생하여 188명의 종업원이 사망하는 대형사고가 있었다. 이 사고는 공장화재 역사상 세계 최대의 인명피해를 기록하게 되었다. 지금까지 82년 동안은 146명의 사망자를 낸 뉴욕 Triangle Shirtwaist공장화재가 최대 인명피해였다. 이 두 사고는 유사한 점이 많다. 우리나라에서도 크고 작은 공장화재가 발생하여 인명피해가 자주 일어나고 있다. NFPA journal 94년 2월호에 게재된 이번 사고를 요약 정리함으로서 공장관리에 참고가 되었으면 한다.

지하공간에서의 화재는 반밀폐 공간이라는 특수성으로 일단 화재가 발생할 경우 대구지하철화재 참사와 유사한 대형참사로 발전된 가능성은 상존한다 지금까지의 방재계획은 화재발생 가능 범위 내를 기준으로 실시되어 왔으나, 테러와 같은 비정상적 화재발생에도 대처가능한 선까지 그 범위를 넓히고 있는 세계적 추세이다. 또한, 지하철은 다른 구조물과 비교하여 화재발생시 화재진압 및 인명구조에 본질적으로 취약한 구조적 특성을 내포하고 있다.(중략)

Purpose: When a disaster occurs, information is collected and sent indiscriminately to the disaster safety situation room, making it difficult to make quick and correct decisions. Therefore, in this study, both the field response team and the situation room attempted to derive the essential information elements for disaster management so that they can identify and respond optimally. Method: In this study, the actual disaster response process was first identified based on the case of large-scale fire disasters in multi-dense facilities. Afterwards, essential information on disaster management was obtained by analyzing the standard manual for large-scale fire crisis management in multi-dense facilities and the fire situation report form prepared at the time of disaster. Result: The Essential information on disaster management was divided into four stages: situation reception·reporting·transmission, total response·regional emergency rescue control group·regional disaster safety task force, operation stage of central emergency rescue control group·central disaster safety task force, and recovery stage. Since then, the information to be collected at each stage and the information relevant to core tasks are presented. Conclusion: The Essential information on disaster management thus obtained can serve as a guide for the person who collects information on site to collect information efficiently. In addition, it is expected that the situation room in charge of disaster response decision-making will receive only the information necessary for decision making, so that it is possible to make a quick situation decision and more efficient disaster situation management.

In case of a fire in urban large structures such as super high-rise buildings, evacuation guidance must be provided to the occupants in order to minimize human deaths and injuries. Therefore, it is essential to provide emergency evacuation guidance when a major fire occurs. In order to effectively support evacuation guidance, it is important to identify major items such as fire location, occupant position, escape route, etc. Also, it is important to quickly identify evacuation areas where residents can safely evacuate from a fire. In this paper, we analyze the CCTV video and propose a method of measuring visibility of the evacuation zone from the smoke caused by the fire in order to determine the safety of evacuation area. To do this, we first extract the background video from the smoke video to measure the visibility of the specific area due to smoke. After generating an edge-extracted image for the extracted background video, the degree of visibility is measured by calculating the change in the edge strength due to smoke.

As a result of increase of high-rise building and complex building in cities, fire damage become larger and complicated. However, law and standards in connection with life safety in the fire is deficient in safety performance and the institution of fire is divided into two parts : the building law and the fire law. The aim of this research is to compare with egress safety rule in advanced countries and to analyze the national standard of egress safety by investigating research data in order to make fire safety rule more effective. On the basis of this analysis, this research also suggested that reform measures should make egress safety in the fire.

최근 대재해 발생의 증가 추세에 따라 손실이 증가되고 담보력이 축소되어 보험손실액이 매년 증가하고 있다. 세계 재보험업계가 대형 재해 및 배상책임 보험 클레임 증가로 인해 이중고를 겪고 있기에 대형위험의 요율 인상이 불가피한 실정이다. 이러한 경색화 상황 속에서 국내 보험사 간의 거래 확대와 더불어 수익성을 고려한 적정한 위험도 평가와 기술적 내부 역량 확대가 요구되고 있다.
