  • This paper presents an intelligent computer system, which can easily diagnose electrical fire causes, without the help of human experts of electrical fires diagnosis. For this system, a database is built with facts and rules driven from real electrical fires, and an intellectual database system which even a beginner can diagnose fire causes has been developed, named as an Electrical Fire Causes Diagnosis System : EFCDS. The database system has adopted, as an inference engine, a mixed reasoning approach which is constituted with the rule-based reasoning and the case-based reasoning. The system for a reasoning model was implemented using Delphi 3, one of program development tools, and Paradox is used as a database building tool. To verify effectiveness and performance of this newly developed diagnosis system, several simulated fire examples were tested and the causes of fire examples were detected effectively by this system. Additional researches will be needed to decide the minimal significant level of the solution and the weighting level of important factors.

  • The purposes of fire investigation are to identify and analyze the causes of fire and, using the results in promoting fire fighting policies, ultimately to prevent fires caused by similar causes and to protect people's life and properties from fire. However, although the patterns of fire are getting more diverse and complicated with the rapid development of industry, complicated with the rapid development of industry, fire fighting organizations are continuing traditional superficial fire investigation without operating a fire investigation department for the reason of insufficient manpower, equipment and budget, losing public confidence. Thus, the present study purposed to propose plans to improve the technicality of fire investigation and win public confidence in fire investigation. First, the technicality of fire investigation should be improved by operating a department and personnel exclusively for fire investigation. Second, fire investigation should be more scientific and precise using high tech fire investigation equipment. Lastly, responsible fire fighting administration should be realized through statistical analysis of the causes of fire and computerization. The results of this study are expected to contribute to the safety and security of our society.

  • This paper aims at the statistical analysis of electrical fire and classification of electrical fire causes to collect electrical fires data efficiently. Electrical fire statistics are produced to monitor the number and characteristics of fires attended by fire fighters, including the causes and effects of fire so that action can be taken to reduce the human and financial cost of fire. Electrical fires make up the majority of fires in Korea(including nearly 30% of total fires according to recent figures), 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 fighters directly ticking the appropriate box on the fire report form or making an assessment of a text description. Therefore, it is highly recommended to develop electrical fire cause classification and electrical fire assessment on the fire statistics in order to categorize and assess electrical fires exactly. In this paper 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 fire statistics systems of foreign countries are introduced and compared.

  • In this study, a fire cause of setting fire to one's own car to collect the insurance is analyzed. Through a close examination of causes of this car fire, it is suggested to improve current practices and institutions: (1) A collection system of fallen vehicle parts or fire debris in the fire site should be established; (2) A system of providing fire site information in detail should be established when a police station requests National Institute of Scientific Investigation (NISI) to examine causes of vehicle fires; (3) When a burned car is suspected of arson, a fire station and a police station should maintain a mutual cooperation system; (4) Procedures of examining the causes of vehicle arson in National Institute of Scientific Investigation (NISI) should be improved; and (5) Recognition of the examination of fire causes and correlation with analysis equipment should be changed.

  • This paper, as an attempt to meet the practical needs in the fire protection field of Korea, has dealt with establishing the identification criteria and prevention theory of electrical fire. The causes analysis of electrical fire was already conducted and then reported by the authors in the Journal of the Korean Institute of Electrical Enginers, October, 1966. This paper is, therefore, the next results of a series of studies on the causes and identification of electrical fire.

  • According to the use of electric power increases, the fire which ignited by electrical causes increases too. In this thesis electrical fires which occurs in the country for the past ten years are analyzed and developed the technology to identify the electrical fire. The focus of study is method to identify the electrical fires. The causes of electrical fire, it is analyzed a short-circuit and a over current, which take the highest ratio compare with other causes. The rationalization of identification, an electrical operating status is continuous monitored and the status can be accessed, black-box for identification electrical fires. The results of the study are the causes of electrical fire are found out logically, and the developed black-box for identification fires.

  • Followings are the analysis of 578 fire accidents occurred at Specific Building In 1995. Fire frequency had been slightly decresed since 1992. In regional, fire accidents in Seoul and Ulsan were higher than the average. Occupational fire frequency order was apartment, factory, buildings over six stories and market place. In addition, the order of life loss was buildings over six stories, apartment and factory. And property loss totaled six times higher than that of Fire Department. Among the causes of fire, electrical fire formed 44.8%, from which we can assume that there were some problems in the investigation of fire causes.

  • 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.

  • The electronics factory fire, that occurred at 15:40 on August 21, 2018, killed nine people and injured six. This study analyzes the causes of many of the casualties from the fire, and is based on fire investigation results and so on. The findings suggest that major causes included failure of the automatic alarm system to function, failure of the emergency broadcasting system to function, the fire suddenly spreading due to polyurethane foam in a ceiling on the 4thfloor, a power outage immediately after the fire started, a sprinkler system that was not working, a delay in reporting the fire, and improper management of fire facilities by a fire safety management company.

  • This paper presents an study on the knowledge based system for diagnosing the fire causes using the Fuzzy Possibility Measure( FPM ) about the electric-fire ignition. The Ignition values needed for causes diagnosis is computed as FPM for electric-fire ignition based on the internal scale technique that assigns numerically the characteristic difference of facts to the-tin-ear scale. For the convinience of inference, ignition sources are classified into seven types : short, ground fault, leakge of electricity, overcurrent, cord junction overheating, bad Insulation and spark. The system for causes diagnosis of electric-fire is composed of Knowledge Acquisition System, Inference Engine and Man-Machine Interface, The diagnosis system is wrritten in an artificial intelligence langusge “PROLOG” which uses depth-first search and backward chaining schemes in reasoning process.
