  • 이 논문에서는 화재조사관련 소방기관의 강점을 분석하고 화재원인조사역량을 강화하는 방안을 제시하였다. 소방기관의 화재조사역량 강화 방안은 화재조사 인원과 조직 및 장비의 보강, 수사권 확보 등에 중점을 두기보다는 현재 소방의 잠재력과 강점을 살리고 내부역량을 강화할 수 있는 것을 중심으로 제안하였다. 제시된 방안으로 1) 화재조사 결과는 소방행정의 토대인 만큼 소방서장의 화재조사의 중요성에 대한 인식전환 필요, 2) 관계자진술을 조기에 체계적으로 확보하는 화재조사체제의 구축, 3) 2회 이상 화재현장을 조사하는 실질적인 화재원인조사 체제의 구축, 4) 기계경비 또는 CCTV 등의 자료를 화재원인조사에 활용하는 화재원인조사 체제의 구축, 5) 화재조사를 고려한 화재진화 활동과 진화 후의 현장보존 체제의 구축, 6) 119구급대 및 구조대와 연계한 화재조사체계의 구축, 7) 화재조사 요원에 대한 사기앙양대책 강구 등이다.

  • 본 연구는 선행연구에서 다뤄지지 않았던 예방소방과 대비소방을 수방수요에 포함시켜 소방예산에 미치는 영향을 실증적으로 분석하고자 수행되었다. 이를 위해 16개 광역자치단체에서 수행된 예방소방행정(건축허가동의, 특정 소방대상물, 다중이용업, 소방특별조사), 대비소방행정(소방교육 및 훈련), 대응소방행정(화재진압출동, 구급출동) 그리고 소방예산에 대한 11년(2008년-2018년)의 패널자료를 이용하여 실증분석을 실시하였다. 분석결과, 예비소방행정의 소방특별조사, 대비소방행정의 소방교육 및 훈련, 그리고 대응소방행정의 화재진압출동은 소방예산에 유의미한 음(-)의 효과가 있는 것으로 나타났다. 한편, 대응소방행정의 구급출동은 0.01%수준에서 소방예산에 유의미한 양(+)의 효과를 미치는 것으로 나타났다. 이는 우리나라 소방행정의 패러다임이 재난수용(복구중심)에서 재난대응(현장대응중심)을 지나 재난대비(대비중심)로 변화되고 있다는 공공정책을 지지하는 연구결과이다.

  • Forest fires inflict great losses of human lives and serious damages to ecological systems. Hence, numerous fire detection methods have been proposed, one of which is fire detection based on sensors. However, these methods reveal several limitations when applied in large spaces like forests such as high cost, high level of false alarm, limited battery capacity, and other problems. In this research, we propose a novel forest fire detection method based on image processing and correlation coefficient. Firstly, two fire detection conditions are applied in RGB color space to distinguish between fire pixels and the background. Secondly, the image is converted from RGB to YCbCr color space with two fire detection conditions being applied in this color space. Finally, the correlation coefficient is used to distinguish between fires and objects with fire-like colors. Our proposed algorithm is tested and evaluated on eleven fire and non-fire videos collected from the internet and achieves up to 95.87% and 97.89% of F-score and accuracy respectively in performance evaluation.

  • In the fire there are fusion signs and damage by fire, and insulation aging and carbonization of the electric wiring in the ignition spot because of special characteristic of the appliance in the electricity fire. Because of the physical factor applied in the damage of fire, the decision of ignition spot by eye investigation is insufficient. In this paper, the cause of electricity fire is researched. The focus is on the operation state of operated MCCB(Molded Case Circuit Breaker) at the time of electricity fire. Through grasping the operation principle of MCCB and the experiment, the state of MCCB after fire suppression is discriminated. The distinction possibility on the exist of electricity fire is proposed.

  • A series of fire experiments has been conducted to provide an improved understanding of the fire structure of under-ventilated compartment fires. A comprehensive and quantitative assessment of gaseous species from the fire was made in the upper layer of fire in a 40 % reduced scale ISO 9705 fire compartment. The global equivalence ratio (GER) concept was used to characterize the fire behavior for various fire sizes, fuel types and ventilation conditions. The oxygen concentration in the upper layer reached to zero near the global equivalence ratio of $0.4{\sim}0.6$ while the carbon monoxide concentration increases with increasing the global equivalence ratio. Classification parameters of ISO19706 were also compared with the reduced scale experimental data for under ventilation fire.

  • The present study investigates the effect of fire growth model on fire development characteristics in a carriage. The parallel processing version of FDS code is used to simulate the fire driven flow in a carriage and two types of fire growth model which are flame spread model and t$^2$ model are examined for the same geometrical condition. The heat release rates(HRR) of both model are similar each other until 30 s after ignition, but the flame spread model predicts 5 times higher than those of the t$^2$ fire model during the quasi-steady fire period. Maximum heat release rate in the case of flame spread model reaches about to 12 MW at 100 s after fire ignition. Also, various database of fire properties for combustible materials and more elaborate combustion model considering the flame spreading phenomena are required for better predictions of fire development characteristics using numerical simulation.

  • The "Ondong tunnel" is not used now where is one of the tunnels in the Janghang line which is from Cheonan to Iksan. The length of the tunnel is 214 m. The location of the fire source is center of the tunnel and the pool fire with heptane is for the fire source. Tests are carried out for the various fire sizes, the height and obstructed/open condition of the fire source. Temperature on the top of the tunnel is measured. Even if the fire size is same, the maximum temperature on the ceiling of the tunnel for the elevated fire source is very larger than the maximum for the ground fire source. As the fire size is lager the maximum temperature on the ceiling is higher. These test results can be very useful for design and guidelines of fire detectors in tunnels.

  • We could analyse the fire behavior using the developed software for fire safety assessment in a large space such as atrium. But Korean building law hasn't admitted the result of fire risk assessment in atrium. In the legislation fire resistant wall or shutter must be required between atrium and office rooms, That has obstructed development of building design and fire protection technique in Korea. From this point of view, we made scenarios of fire spread between atrium and office rooms, and then computed fire spread and fire phenomena using FASTLite and Breakl. In this study, we can decide that fire compartmentalization between atrium and office rooms doesn't require in Atrium building if the material and fire protection system were reliable. Consequently, Korean Fire Protection Regulations have to consider in direction of increasing freedom of building.

  • 화재현장은 바람의 방향과 세기, 가연물의 조건, 건물의 형태 등에 따라 다양하게 소훼형태가 변하기 때문에 발화부와 화재원인을 판단함에 있어 세심한 주의가 필요하다. 본 연구에서는 화재 조사자들이 곤란을 겪고 있는 환기지배와 연료지배에 따른 연소형태, 인화성물질에 의한 바닥재의 탄화형태와 낙화(落火)물에 의한 연소흔적을 사례를 통해 살펴보고 조사방법을 제시하였다.

  • Recently, advanced countries assessment the risk of fire to prevent large-scale damage to high-rise buildings, In addition, performance-Based design, which is a fire risk assessment, is being conducted in Korea to prevent massive damage to high-rise buildings. However, unlike advanced countries, fire risk assessment in Korea is subject to fire risk assessment only for objects subject to consent from fire-fighting facilities such as building permits, When building engineers and fire-fighting engineers assessment the risk of fire, It has always been discussed because the results vary depending on which part of the evaluation is focused between economic feasibility and safety. Therefore, in this study, we would like to propose a fire risk assessment process suitable for domestic conditions by comparing the process of performance-based design, which is a domestic fire risk assessment, and the process of Iso/TC 16732 which is an overseas fire risk assessment.
