  • The fire of Sungnyemun, National Treasure of No.1, gave to the Korean people and fire investigators big pains. The aim of this study are the identification of combustion traces and fire patterns of wooden building fire, burned with an accelerator, after spraying flammable materials on the wooden floor through the field study observation. Also, in the case of the similar fire, these results will be as good references to fire investigators for accurate investigations.

  • For many years concrete has been the major building material for most construction. It is of primary importance that fire fighters or fire investigators have a full understanding of the properties of concrete so that better control of the fire scene is achieved. This, in turn, not only help to ensure a safer fire-fighting job but also a more successful fire investigation. So far as the fire scene investigation in concerned, knowledge about the thermal behaviour of concrete can help the investigators to determine the highest temperature that a particular spot of a fire scene has ever reached thereby providing data which may be of value in reconstructing the course of the fire.

  • It is very difficult for fire investigators to analyze the fire debris in fire scene to figure out the reason of fire. ASTM E 1618 method with Gas Chromatoghraphy-Mass Spectrometry was used to analyze the ignitable liquid residues in fire debris prepared in our laboratory. According to fire cases, sample handling procedure methods and fire debris store time, different total ion chromatograms were obtained. We wish the study will be helpful to fire investigators to figure out the reason of fire.

  • When enforcing fire investigation, duty for basic principles, responsibility of investigation, report deadline, and all sorts of standard forms are based on fire investigation report regulation which is internal instructions. This study has a purpose to prepare alternatives that are absent in Korea or have to be strengthened by comparing and examining Japanese and Chinese fire investigation report regulations with Korean one. As a result, it appears that Korea needs to standardize the report deadline of urgency fire and general fire into 30 days when additional investigation is needed, have investigators draw delays reports up when they exceed the deadline not to make work vacuum, and found and organize forms of certificate of custody and return for all fire related materials when investigators require data from fire-related people, to improve whole systems.

  • The burned patterns of fire are changed very diversely according to the direction of wind, conditions of combustibles, shape of buildings and so on in the fire scenes. And careful attentions are required on the determining of ignition point and fire causes. In this study, we examined that the burned pattern of fuel controlled fires and ventilation controled fires that impose a heavy burden on fire investigators, carbonized marks of floor, formed by flammable liquids, and combustion marks of falling firing materials through the fire cases. We suggest a proper fire investigation method.

  • It is often thought that when a fire is found in parked motor vehicles, the fire may occur after an engine stops. Also, it is easy to judge that when motor vehicle fires occur during engine stopping, it may be caused by arson or electrical causes irrespective of a fuel system. This study analyzed motor vehicle fires which occurred in operation but were found after parking and revealed that these fires were caused by the defect of a fuel system and the same motor vehicle types had fires by the same causes. Moreover, this study provided judgement process of major fire causes and periods for fire investigators to apply when investigating fires of parked motor vehicles. And this fire is related to automotive products liability.

  • Electric fire breaks out by various causes such as electric short, overload(over current), leakage current, poor contact, static electricity, insulation deterioration, partial disconnection and etc. In this paper, we studied analysis technique for scientific and systematic judgment for distinction of electricity fire existence and nonexistence, and described about electricity fire cause analysis process for collecting physical evidences. We handled external form analysis, Substance extension analysis, X-ray transmission analysis, cross-section analysis, thermal analysis, chemical structure analysis, surface structure analysis, component analysis, electrical properties analysis, and circuit analysis by analysis technique for electricity fire cause judgment. We expect that analysis technic elevation and correct cause of fire analysis of scene of a fire investigators and analysts through this paper which see help.

  • In this experimental report, We introduce an idea of thermal corrosion in sandwich panel. In brief, Because the structures of sandwich panel are easily collapsed by thermal damage caused by a fire, it is very difficult to investigate a point and origin of fire. Therefore, If the shapes of thermal corrosion are reconstructed according to change of temperature and lapse time by experiment in sandwich panel, it is very simple task that fire scene investigators search for a point and origin of fire. As a result, we present the difference of thermal corrosion between samples which are applied heat by many-sided variable, such as temperature, heating time, lapse time, humidity, and others.

  • This paper presents research about the development of electrical fire cause classification in order to improve the reliability of electrical fire statistics and to collect electrical fires data efficiently. The incorrect and biased knowledge for electrical fires changed the classification of certain types of fires, from non-electrical to electrical. It is convenient and required to develop the standardized form that makes, in the assessment of the cause of electrical fires, the fire investigators directly ticking the appropriate box on the fire report form or making an assessment of a text description. In this study, newly developed electrical fire cause classification structure, which is well-defined hierarchical structure so that there are not any relationship or overlap between cause categories, is suggested. Also the suggested classification structure can be used for electrical fire investigation and statistics, which minimizes the mistake that diagnose non-electrical fires into electrical ones.
