Fire investigation to examine ignition and combustion enlargement etc., to assess fire damage and to investigate a fire suspect, is used as a valuable data for better fire suppression and fire prevention police. Fire investigation is divided in to fire-cause investigation, fire-damage investigation, and fire-criminal investigation. At present, fire-cause investigation is lacking In scientific technology; specially is deficient in accurate damage assessment. And considering fore criminal investigation, since the police lacking in specialty on fire take exclusive charge of fire criminal investigation upon general investigation, it is difficult to investigate fire criminal effectively. Finally deficiency in fire investigation operates as very big blind-spot in fire safety having important axis in social safely; the loss is shifted on nation's shoulder. To solve those problems, legal, institutional, operational preparation is urgent. And so, this study tried to stabilize specialty of fire-fighting to offer more active, qualitative fire administration service, and to contribute to public peace and welfare by grasping problems after diagnosing Korean fire investigation and proposing the solutions.

Static-electricity-induced fires and explosions persistently occur every year, averaging approximately 80 and 20 cases annually according to fire statistics provided by the National Fire Agency and industrial accident statistics provided by the Ministry of Employment and Labor, respectively. Despite the relatively low probabilities of these accidents, their potential risks are high. Consequently, effective risk assessment methodologies and accident investigation strategies are essential for efficiently managing static-electricity hazards in fire- and explosion-prone areas. Accordingly, this study aimed to identify the causal variables essential for accident investigations, thereby facilitating risk assessments and the implementation of effective recurrence prevention measures to mitigate static-electricity hazards in fire-and explosion-prone regions. To this end, industrial accident statistics recorded over the past decade (2012 to 2021) by the Ministry of Employment and Labor were analyzed to identify major fire and explosion incidents and related industrial accidents wherein static electricity was identified as a potential ignition source. Subsequently, relevant investigation reports (63 cases) were thoroughly analyzed. Based on the results of this analysis, existing electrostatic fire and explosion risk assessment techniques were refined and augmented. Moreover, factors essential for investigating electrostatic fire and explosion disasters were delineated, and the primary causal variables necessary for effective risk assessments and scientific investigations were derived.

To understand electrical fire, the cause of it is classified into overcurrent, short circuit, leak, joint, overheat, accumulation of heat, spark, deterioration of insulation, static electricity, and lightning etc. and explained. And then by the precautions to it, proposed to the improvement of electric products, the completeness of safecty management and the use of alarm systems.

This paper studied analysis of deflagration rapid propagation of burning through only a few second and fire cause into the Busan indoor shooting range. We carried out combustion experiment of sound-absorbing materials extensively used, to analyze propagation path of burning in indoor shooting range. From the experimental results, general sound-absorbing materials were rapid burned simultaneously with ignition and in case of attached gunpowder residue, they were burning about tripled by comparison with general sound-absorbing materials. The incombustibility sound-absorbing materials had all gone out simultaneously with ignition, but they were burning similar to general type materials in case of attached gunpowder residues. In order to analysis of the cause of fire, we calculated kinetic energy of bounced off bullet, from result, if the bounced off bullet impacted gunpowder residues, the gunpowder residues were possible to ignite by the bullet.

In this study, we investigated the cases where there were many opinions in the judgment of the cause of ignition in the case of 20 cases of frozen warehouse fire that occurred in 2017.The research methodology is the scientific fire survey method prescribed by the NFPA 921 CODE. Scientific fire investigation method is fire investigation method by logical reasoning through hypothesis setting, minimizing errors in judgment of ignition source. On the other hand, unscientific fire investigation methods cause many errors by the intervention of irrational factors such as subjective estimation, reasoning judgment, etc. This eventually leads to the problem of human and material responsibility and academic deterioration. In particular, fire not seen as compared to sighted fire makes more errors in ignition sources in the cause investigation. In this study, we set the hypothesis A and hypothesis B based on the review of the fire investigation report and the field survey on the fire case of the cold storage warehouse front line that occurred at ** city ** Mart in 2017.The set hypothesis was tested by the NFPA 921 code. This analytical method will be constructed by NEW Paradigm as a source of fire that is not seen in the future and a source of ignorant fire.In addition, the experimental data of this study will be used to inform the manufacturer and operator of the refrigeration warehouse and serve as basic data for fire prevention.

It has been known that the nosebleeding is a king hemorrhage occured to be damaged yang-rak (陽略) & lung. the results obtained were as follows; 1. The cause of nosebleeding were divided internal external, these were lung-heat(肺實熱), wind-heat(風熱), dry-heat(煥熱), wind-cold(風寒), summer-heat(暑熱), and those were transporting of Liver-fire(肝火犯肺), Liver-kidney-fire(肝腎陰虛熱傷肺), Stomach-fire(胃火熾盛), Heart-fire(心火千肺). 2. The treatment of external ; Chungpaesulyul(淸肺泄熱), Yanghyuljihyul(凉血止血), Sanpungchungyul(散風淸熱), Jaeumchungjo(滋陰淸煥). 3. The treatment of internal ; Chungkansahwa(淸肝瀉火), Yanghuljihyul(凉血止血), Jayumganghwa(滋陰降火), Chunguysahwa(淸胃瀉火). The cause of nosebleeding was almost heat (fire), and the treatment were Sanpyo(散表) & Chungri(淸裏).

We identified objectively the ignition spot of real fire scene and electrical machinery and appliances in sections which were acted for fire cause. By pointing out the actual condition of dealing electronic devices and researching the way of solution, I will presents the fundamental materials which will help to prevent recurrence.
