  • 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.

  • Cause of Bucheon LPG refueling station accident could not be clearly verified because of opposite talking of men reponsible for the accident the accident, damaged by BLEVE and fire, and no systematic fire investigation. After two and half years, recently first judgement has been carried out. But competitive arguement is going on and first leak point of massive LPG will not be clearly identified with evidences acquired by now. This accident gave us many instructions and advices. Specially, massive LPG leak can result in pool fire and safety of underground-installed storage tank is proved by no damage in the strong BLEVE.

  • Following the Fukushima accident, a special safety inspection was conducted in Korea. The inspection results show that Korean nuclear power plants have no imminent risk for expected maximum potential earthquake or coastal flooding. However long- and short-term safety improvements do need to be implemented. One of the measures to increase the mitigation capability during a prolonged station blackout (SBO) accident is installing injection flow paths to provide emergency cooling water of external sources using fire engines to the steam generators or reactor cooling systems. This paper illustrates an evaluation of the effectiveness of external cooling water injection strategies using fire trucks during a potential extended SBO accident in a 1,000 MWe pressurized water reactor. With regard to the effectiveness of external cooling water injection strategies using fire engines, the strategies are judged to be very feasible for a long-term SBO, but are not likely to be effective for a short-term SBO.

  • The purpose of this paper is to report gas fire accident based on classification of the major gas fire causes (including handling mistakes, inferior goods, etc.), fire classifications (fire, explosion, leakages, etc.), damage levels(1st, 2nd, 3rd, 4th grade levels), casualties (death, serious wound, slight injury) since gas fire has been generated according to growth of gaseous fuel consumption on home and enterprises with various accident causes. Among gaseous fuels, LPG facility can be c1assified as gas container, pressure regulator, gas hose, interim valve, combustion port. Any fire or any explosion can be caused from handling mistakes, inferior goods on each parts as stated above. Exact gas fire causes shall be identified based on previous case studies on similar fires with consideration of lesson learns.

  • The purpose of this study is to explore appropriate fire safety education programs for young children by both examining the actual damage condition and problems associated with fire accident in young children and considering fire safety education programs in America and legal basis for fire safety education in Korea. The results are as follows. First, the mortality of young children by fire accident in Korea is higher than that of U.K, Germany, and Sweden. Second, it is defined by the Child Welfare Law in Korea to implement the mandatory fire safety education for young children in kindergarten and preschool programs. Third, in order to activate fire safety education programs for young children, the fire safety education needs to be suitable for children's developmental characteristics, and various audiovisual materials and activity programs should be developed and provided. Fourth, fire safety education both for early childhood teachers and parents needs to be interrelated and systemized to reduce the risk of fire accident.

  • The traffic accident of Fire engine takes place very much, compared with that of the past. The reason is that there is a lot of the increase of the demand in the fire, rescue, first aid, and the public request. Also, because the Fire engine should go out at the place of the accident very quickly, it should inevitably violate the traffic regulations. Therefore, this is due to the traffic accident. Despite the urgent situation in the infringement motive of traffic regulations, the outbreak of the traffic accident does not vary largely from the degree of the disadvantage. Accordingly, a fire officer should take charge of his social and economic disadvantage by himself. In this situation, a fire officer has no choice but to start moving passively not to be afflicted with his own disadvantage. Most of the situations concerning the fire fighting are the ones to be controlled urgently. Nevertheless, because of the disadvantage of the traffic accident, passive mobilization of the fire fighting equipment is the heavy burden of all the people of the nation. Therefore, Special institutional safety device should be ready for the protection of the life and property of all people. The special law concerning the processing in the accident of the emergency car needs to be revised. By establishing this special law, the government should not provide the officer who drives the fire engine with the disadvantage caused by traffic accident.

  • In the subway fire case, it is important that judge accuracy subway fire type and on the initial response minimize accident damage. But when the subway fire accident occurring, if it have know impossible that accuracy subway fire type to judge at once though witnessing driver or emergency response staff. This study suggests type of five senses that using information of five sense take to the subway fire accident information which analyses five senses as occurring subway fire accident. Also it is proposed that emergency response system though fire scenario by using Activity-Action Diagram(AAD).

  • In order to propose the method of the consequence analysis for fire accidents by the heavy gas release and to obtain optimum conditions of parameter selections, the consequence analysis for jet fire by the accident of xylene vapor release were performed. And the effect and the sensitivity analysis of parameters affecting the consequence were investigated. Simulation results showed that important parameters affecting results of the xylene vapor release accident were mainly hole diameter, interested distance, wind speed, and so on. For the jet fire, the accident result and the sensitivity of thermal radiation were increased with the decrease of interested distance and the increase of hole diameters, and the accidental result was increased as the increase wind speed, but the sensitivity of thermal radiation was decreased.
