  • 2009년 실화책임에 관한 법률이 개정된 이후, 실화 책임과 관련하여 이해당사자들은 서로 배상책임액 산정을 두고 소송을 통해 제반 이슈를 해결하고 있다. 화재사고는 직접 피해와 함께 연소 확대로 인한 추가 피해의 구분이 어려운 복잡한 구조이기 때문에, 이에 따른 실화 배상책임액 산정의 경우도 타당성과 신뢰성이 확보된 프레임워크의 수립과 활용의 필요성이 증가하고 있다. 본 연구에서는 이러한 실화배상책임액 산정을 위한 프레임워크의 수립을 위하여 정부가 발표한 화재 통계자료와 선행 연구자들의 연구 데이터 및 결과를 기반으로 상기 프레임 위크에 적용할 화재의 유형화와 실화 책임 주체의 정리 및 적용 기법(AMEA, FTA)을 통해 정성 항목을 정량화하였으며 확률적으로 처리하고, 그 결과를 제시하였다.

  • The helideck structure must satisfy the safety requirements associated with various environmental and accidental loads. Especially, there have been a number of fire accidents offshore due to helicopter collision (take-off and/or landing) in recent decades. To prevent further accidents, a substantial amount of effort has been directed toward the management of fire in the safety design of offshore helidecks. The aims of this study are to introduce and apply a procedure for quantitative risk assessment and management of fires by defining the fire loads with an applied example. The frequency of helicopter accidents are considered, and design accidental levels are applied. The proposed procedures for determining design fire loads can be efficiently applied in offshore helideck development projects.

  • 2005년 개정된 소방법에 의하면 11층 이상의 신축 아파트는 전(全)층에 스프링클러를 설치하게 되어 있으나, 2005년 이전의 소방법은 16층 이상의 아파트에 대해서 16층부터 최상층까지 스프링클러를 설치하여 화재 시에 작동하여 소화를 하게끔 되어 있다. 본 사례는 2005년 이전에 지어진 17층 아파트의 17층 한 가구에서 담배에 의한 실화로 추정되는 화재에 의해 피해자가 사망한 사건으로서 유족 측에서 화재 시에 스프링클러가 정상작동하지 않은 이유에 대해 의문을 제기한 사건이다. 현장조사를 통해 동 아파트 16층에서 화재감지기를 작동시키면 스프링클러가 정상작동 하였으나, 17층에서 화재감지기를 작동시키면 스프링클러가 작동하지 않음을 확인하였고, 동 17층에서 스프링클러가 작동하지 않은 원인이 스프링클러제어기의 프로그래밍 결함에 있다는 것을 밝혔다.

  • Offshore oil and gas process plants are exposed to hazardous accidents such as explosion and fire, so that the structural components should resist such accidental loads. Given the possibilities of thousands of different scenarios for the occurrence of an accidental hazard, the best way to predict a reasonable size of a specific accidental load would be the employment of a probabilistic approach. Having the fact that a specific procedure for probabilistic accidental hazard analysis has not yet been established especially for explosion and fire hazards, it is widely accepted that engineers usually take simple and conservative figures in assuming uncertainties inherent in the procedure, resulting either in underestimation or more likely in overestimation in the topside structural design for offshore plants. The variation in the results of a probabilistic approach is determined by the assumptions accepted in the procedures of explosion probability computation, explosion analysis, and structural analysis. A design overpressure load for a sample offshore plant is determined according to the proposed probabilistic approach in this study. CFD analysis results using a Flame Acceleration Simulator, FLACS_v9.1, are utilized to create an overpressure hazard curve. Moreover, the negative impulse and frequency contents of a blast wave are considerably influencing structural responses, but those are completely ignored in a widely used triangular form of blast wave. An idealistic blast wave profile deploying both negative and positive pulses is proposed in this study. A topside process module and piperack with blast wall are 3D FE modeled for structural analysis using LS-DYNA. Three different types of blast wave profiles are applied, two of typical triangular forms having different impulse and the proposed load profile. In conclusion, it is found that a typical triangular blast load leads to overestimation in structural design.

  • Background: As one of the most frequently occurring accidents in a chemical plant, a fire accident may occur at any place where transfer or handling of combustible materials is routinely performed. Methods: In particular, a jet fire incident in a chemical plant operated under high pressure may bring severe damage. To review this event numerically, Computational Fluid Dynamics methodology was used to simulate a jet fire at a pipe of a compressor under high pressure. Results: For jet fire simulation, the Kemeleon FireEx Code was used, and results of this simulation showed that a structure and installations located within the shelter of a compressor received serious damage. Conclusion: The results confirmed that a jet fire may create a domino effect that could cause an accident aside from the secondary chemical accident.

  • Detection of fire accelerants from fire residues is critical to determine whether the case was arson or accidental fire. However, to develop a standardized model for determining the presence or absence of fire accelerants was not easy because of high temperature which cause disappearance or combustion of components of fire accelerants. In this study, logistic regression, random forest, and support vector machine models were trained and evaluated from a total of 728 GC-MS analysis data obtained from actual fire residues. Mean classification accuracies of the three models were 63 %, 81 %, and 84 %, respectively, and in particular, mean AU-PR values of the three models were evaluated as 0.68, 0.86, and 0.86, respectively, showing fine performances of random forest and support vector machine models.

  • There are many origins of fire which are offered by many path, such as cigarette-butt, light of match, playing with fire, arson, and other, in and around wastebasket. Because of above-mentioned thing and the quality of the plastic, it is very difficult to discriminate the difference of burned pattern between in and around wastebasket, between an accidental fire and arson in oder to investigate the point of fire. In this study, the wastebaskets filled up with 2/3 combustibles, and then, in and around wastebasket using the gas lighter by ignitor, and we observe how the fire spread. As a result, if wastebaskets are burned inside the limit 50%, we discriminate the difference of burned pattern between in and around wastebasket. But, if wastebaskets are burned more thant 50%, it is impossible to discriminate the difference of burned pattern between in and around wastebasket.

  • There have been more than 40,000 cases of fires in Korea in the last three years. However, as 'Accidental Fire Liability Act' was judged to be non-conform to the Constitution in 2007, the damages by light mistakes should be compensated. Accordingly, disputes such as compensation claims, litigations and indemnification cases of the victims of fire increased. However, it is so difficult for victims of fire cases to take proper action. So, this study is to help victims of fire cases in the disputes and compensation claims of the victims, and to find actual and practical support system based on the analysis of compensation status. To help victims of fire cases, we need to survey about victims of fire cases with multiple victims. That survey is analyzed to find support plan for victims. Furthermore, to find support plan the current law is needed to be analyzed and reviewed to revision. It is also tried to identify problems in the operation of the Center for victims of Fire currently operated by fire stations and to find countermeasures. In addition, the status of subscription and problem of fire insurance for the compensation for the victims and the method to increase fire insurance subscription rate will be studied.
