  • 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 January, 2005, "railroad security law" was presented, preparing the systematic equipment that allows several railroad operators to consider the railroad security issue, and each of railroad operative institutions accepted such situation that construct the integral railroad security system, resulting in constructing the emergent system coping with the railroad fire accident through the relevant study business to improve the railroad security efficiency against fire. This study tried to present the studying direction on developing the emergent educational program coping with the railroad fire accident, which is distributed to the spot, about the railroad worker for improving the railroad security efficiency against fire through the education of systematic and efficient emergent countermeasure procedure of emergent system against the railroad fire accident.

  • Among the method of aerial fire firefighting, the indirect attack is efficiency way to protect main facilities and it is the aerial fire line construction. According to this study is suggested the fire line construction strategy of indirect attack by helicopter suitable Korea forest fire on theory consideration of indirect attack and experience in practical scene. This study defined that main key points of the fire line construction are accuracy, large quantity, and quickness. Main protection facilities are devided as caution area, warning area, danger area and concern area. Also, it suggested stage-by-stsge from 1 step to 3 step for the aerial fire firefighting correspondence strategy and the fire line construction model. I regard that this study's indirect attack method of the aerial fire firefighting of the fire line construction may be understand about indirect attack tactics and application of indirect attack which is assistance to raise of capability of the aerial fire firefighting with effectiveness and efficiency.

  • The purpose of this paper is to predict the situation of leak in closed space using an Artificial Neural Network (ANN). The existing system can't monitor the whole He situations with on/off signals. Especially the first stage of data determines the leak spot and intensity is disregarded in gas accidents. To complement these faults, a new prototype of monitoring system is proposed. Ihe system is composed of'sensing systenL data acquisition system computer, and ANN implemented in software and is capable of identifying the leak spot and intensity in closed space. The concentration of gas is measured at the 4 different places. The network has 3 layers that are composed of 4 input Processing Element (PE),24 hidden PEs, md 4 output PEs. The ANN has optimum condition through several experiments and as a consequence the recognition rate of93.75% is achieved finally

  • 본 연구는 북한 및 비무장지대 등 접근불능지역에 대한 기상에 의한 산불발생예측 알고리즘을 개발하고, 실제 현장과 현업에서 활용할 수 있는 실시간 산불위험예보 체계를 개발하는데 있다. 산불기상위험지수 산출 모형 개발을 위해 자료의 취득과 검증을 위한 현장조사가 불가능하다는 연구적 한계가 존재하므로, 이를 해결하기 위해 MODIS 위성자료를 활용하여 접근이 불가능한 지역의 산불발화지점(fire spot)을 과학적 근거를 가지고 추정하였다. 추출된 산불발화지점을 대상으로 기상청에서 생산된 과거 기상 재분석자료(5㎞ 해상도)를 활용하여 산불발화지점에 대한 기상특성을 추출하여 데이터베이스화 하였다. 접근불능지역의 산불발화지점에서 추출된 기상요소들은 산불발생과 기상요인들과의 통계적 상관성과 산불발생 유무(산불발생 1, 산불 미발생 0)를 추정할 수 있는 로지스틱 회귀모형을 활용하여 실시간 기상변화에 의한 산불기상위험지수(Fire Weather Index, FWI)를 개발하였다. FWI 모형의 예측정확도는 66.6%로 나타나 모형의 적합도는 비교적 높은 것으로 나타났다. 이 연구결과는 남 북한의 산불 방지를 위한 정책 입안자들의 의사결정에 유용하게 활용될 것으로 기대한다.

  • Analyzed in the NFDS, The average number of fires in vinyl temporary buildings is more than 1,000 in annually. And the number of deaths and injuries was around 30 people in every year. According to the National Fire Agency, There are 142,386 vinyl temporary buildings for Agriculture and Fishery, of which 4,720 are residential vinyl temporary buildings in illegally. Model house is subject to regulation in fire-related law. But, even though it's the same temporary building, Vinyl temporary building is not subject to regulation. For this reason, Vinyl temporary buildings are left in the blind spot of fire safety. Therefore, In this study, We propose that amend of Act on installation and management of firefighting systems, make of temporary fire safety controller, develop and apply of alarm system that is connected to a single-alarm smoke dretector, organize and operate volunteer fire brigade of the crop group to prevent and extinguish the fire.

  • The objectives of this paper investigate the effect of installed spacing on the activation of spot type heat detection devices. The flow of hot gases under a ceiling resulting from the impingement of a fire plume activates heat detectors and sprinklers. Local temperature and velocity in this ceiling jet are usually expressed with the function of a ceiling height, the distance from a fire location and the heat release rate of fire. And detectors having different. RTI respond in different ways to the same temperature and velocity of ceiling jet. Thus great care should be taken to decide installed spacing of heat detection devices by considering above effects.
