  • Fire incidents, which occur every year, cause huge damage to properties and humans. Significant time and costs have been invested in minimizing and responding to such accidents. With the recent advances in the development of spatial information, in the firefighting field, studies have been conducted to effectively bring fires under control using GIS(Geographic Information System). Most of such studies, however, focused on individual analyses of firefighting-related factors, but comprehensive research on the vulnerability factors in fire control activities, a major part of firefighting activity, has yet to be done. This study sought to pinpoint and analyze the factors that obstruct fire controlling, and to gather relevant data and create GIS-based databases. Based on such database, GIS-based overlay analysis was conducted to produce a fire control vulnerability map. The findings of this study will enable a quantitative analysis of firefighting obstruction factors to assist the personnel engaging in firefighting in rational decision-making, such as in formulating a firefighting operation plan for securing golden time.

  • 최근 빗물이 우리가 앞으로 이용할 수 있는 수자원이라는 사회적인 인식의 변화와 함께 빗물이용이 더욱 요구되어졌다. 특히 빗물의 이용 저류 침투를 목적으로 하는 우수 관리에 대한 관심이 증가하면서 빗물이용시설의 설치, 운용의 필요성이 대두되고 있다. 이에 반해 화재발생은 해마다 증가하고 있으며, 화재 증가는 소방력 활동의 증가로 귀결되는데 현장활동 인력과 장비 그리고 화재를 진압하는데 사용되는 소방용수 증가를 의미한다. 따라서 본 연구는 빗물을 소방용수로 즉, 화재진압시 활용 가능성과 수자원 절약, 화재 사각지역 해소 측면을 살펴보기 위해서 통계분석, 현장조사, 기존 빗물이용시설 및 향후 완공 예정인 우수유출저감시설 활용과 소방용수 미설치 지역과 소방관서 옥상에 빗물이용시설 설치 방안을 제시하였으며, 그에 따른 공공서비스 확대와 경제성 분석을 통하여 다음과 같은 연구결과를 도출하였다. 첫째, 기존 빗물이용시설을 소방용수로 적극적으로 활용해야 한다. 빗물이용시설의 주 용도로 조경용수, 청소용수, 소방용수로 나눌 수 있는데 이수 측면에서 화재가 발생하지 않으면 소방용수로서 이용이 거의 없는 실정이다. 이는 해당 건물관계자나 소방대원들이 빗물이용시설을 인식을 못하고, 사용과 접근성 불편으로 상수도와 연결된 소화전에 의존하는 경우가 많다고 본다. 둘째, 상수도시설이 없는 지역은 빗물이용으로 소방용수를 확보해야 한다. 섬, 산간, 고지대, 농촌지역 등 상수도 서비스를 공급받지 못하는 지역은 화재발생시 수원확보곤란으로 인명과 재산피해의 증가요인으로 작용할 수 있다. 공공서비스 확대차원에서 화재 사각지역을 해소하기 위해 지붕면을 이용한 각 가정마다 또는 공동 빗물저장소와 지형의 비탈면을 이용한 빗물이용시설 설치로 소방용수 확보의 필요성을 확인했다. 셋째, 소방관서 신설시 빗물이용시설을 도입하여 설치한다. 화재통계와 현장조사를 통하여 소방차 출동대기부터 화재진압까지 많은 양의 물이 사용되는 것으로 파악되었다. 대부분 먹는 물 즉, 상수도를 이용한다는 점에서 수자원 절약과 화재진압에 사용된 물은 재생 불가능이라는 환경보전 측면에서 빗물이용으로 해답을 찾아본다. 따라서 빗물을 많이 저장할 수 있도록 옥상, 부지 등 집수면적을 확대하고 이에 적합한 저류시설을 갖춘 빗물이용시설을 설치한다. 끝으로 신속하고 효율적인 화재진압이 중요한 만큼 빗물을 소방용수로 활용하고자 할 때는 언제 어디에서나 현장 접근성, 사용 편리성, 충분한 수량을 고려해야한다.

  • Every crew are in great peril that they should put out a fire on board in person due to a property of ship isolated. Accordingly, it is essential to verify whether the fire-fighter's outfits and fire-fighting scenarios in accordance with present regulations are safe and effective actually. As a result of comparison between shore fire-fighter's outfits and fire-fighting scenarios and those on ship and statistics calculation of the place and frequency of the fire of actual ship, present limitations of fire suppression system and fire-fighter's outfits were proved. In addition, derive the distance to the place on ship that has highest frequency of fire occurrence from examining actual ship's drawings according to their description and size. Finally from experiments in more experimental groups by changing numbers of actual fire-fighters and environment and conduction of survey of a number of crew in active service on ship, the most effective fire-fighter's outfits system and fire-fighting scenarios will be derived.

  • In this study, the effects of the characteristics of droplets of water spray on suppression of fire were analyzed numerically using fire dynamics simulator (FDS) 6.5.2. Additionally, the fire suppression characteristics by the water spray nozzle, including the extinguishing coefficient (EC), droplet size distribution function (SDF), median volumetric diameter (MVD), and droplets per second (DPS), were evaluated in terms of the decreasing normalized heat release rate (HRR) curve and cooling time. It was observed that with increase in the EC, the normalized HRR curve decreased rapidly, and the changing MVD affected the suppression of fire. In case of mono-disperse, the normalized HRR curve decreased slowly with the increase in DPS. On the contrary, in case of multi-disperse, the normalized HRR curve decreased rapidly even with a small increase in DPS.

  • 이 논문에서, 우리는 휴머노이드 로봇인 다윈에 내장되어 있는 색 접근법을 이용한 비전 프로세싱을 통해 화재가 난 위치에 접근하며, 적정거리에 도달했을 경우, 다윈의 손에 들고 있는 분무기로 화재를 진압 하도록 하는 "화재진압다윈"을 만들었다. 여러 논문에서 화재진압용 로봇들을 소개하였지만, 우리는 다윈이라는 휴머노이드 로봇을 이용하여 화재를 진압하도록 하였다. 아직까지 휴머노이드 로봇을 실용적으로 사용하기에 많은 문제들이 존재한다. 하지만 휴머노이드 로봇 분야는 사람이 할 수 있는 사다리 타기, 계단 오르기, 장비 다루기 등과 같은 여러 가지 기능들을 수행할 수 있음으로 많은 잠재력을 가지고 있다. 이번 리서치에서 시도한 화재진압다윈 역시 실용적인 부분에서는 아직 많은 미흡한 점들이 있지만, 미래의 잠재력에 한발자국 나아갔다는 부분에 있어서 많은 의의를 둔다.

  • This study was conducted to provide a method for fire suppression in a central area inside the roof of a wooden cultural property using a gas extinguishing apparatus, which is used as one of fire suppression methods with view to preventing valuable wooden properties inherited from ancestors from being destructed by fire. For a wooden property, it is very difficult to suppress fire when combustion spreads to a central area inside its roof, so it is impossible to put out a fire without destructing it. Such a fire fighting apparatus as a sprinkler, etc., installed in modern structures, is very effective, but the possibility of damaging a cultural property is highly probable after installment and operation, which leads to its low adaptability to a wooden property. Thus, the necessity of developing a fire suppress ion apparatus was raised to minimize the said problem and to obtain the desired results, and the need of making a plan on the installment was also raised based on the results of a test whose validity was proven. The central area inside a roof is a traditional - architectural style which is found in Korean wooden structures only, so it is impossible to discover similar cases in foreign countries. For this reason, this study was conducted to verify the effectiveness by developing a fixed fire suppression apparatus designed considering the speed and effectiveness in fire suppression. This study was sequentially carried out in the following steps. First, a frame for this study was made and the specific plan on a fire suppression method was established. Then, a fire suppression apparatus was installed. In the first step, the effectiveness for fire suppression was tested by installing valve open - punched - main water pores, and in the second step, the same effectiveness was tested by valve opened - punched - injection ports. For a wooden property similar to "Sungnyemun"(Gate of Exalted Ceremonies), its central area of the roof decides whether the fire suppression is successful or not, so the opinions on how to put out a fire were presented in this study, and thus the objective data to establish a method on fire suppression in a wooden structure(cultural property) was secured. Lastly, a scientific verification in the effectiveness for fire suppression measures was presented by installing a gas - fixed fire suppression apparatus.

  • Present study deals with performance analysis and experimental investigation of an inert gas generator (IGG) which can be used as effective means to suppress fire. The IGG uses a turbo-jet engine to generate inert gas for fire extinguishing. It is generally known that a less degree of oxygen content in the product of combustion will increase the effectiveness of fire extinguishing. An inert gas generator system with water injection has advantages of suffocating and cooling effects that are very Important factors for fire extinguishing. Some aspects of influencing parameters, such as, air excess coefficient, compressor pressure ratio, air temperature before combustion chamber, gas temperature after combustion chamber, mass flow rate of water injection etc. on the performance of IGG system are investigated.

  • This study describes the development of a long-distance hose for ultra-high pressure operation, which can be used in conjunction with an ultra-high pressure pump and can be effectively applied to the fire suppression of high-rise buildings and a long, large tunnels. Also, it has phosphorescent properties, which can help to secure the withdrawal route of the fire-fighters when they are threatened by the fire. We developed an ultra-high pressure hose aiming at a pressure of 3 MPa and a flow rate of 2000 lpm and developed an ultra-high pressure fire hose that can withstand this very high pressure by using a double jacket, triple polyurethane coating and warf (Wp) of 52. In order to ensure the performance of the developed ultra-high pressure hose, its structure, appearance, leakage at high pressure, length and elongation were inspected by a certified certification agency, who also subjected it to a peeling test, friction test, breaking pressure test and free fall test. Also, it was studied in addition to the luminescent high-pressure hose for fire-fighting. In the phosphorescence test, the luminance measurement value was more than the reference value of the luminance test after 40 minutes, which confirmed that its performance was satisfactory for fire-fighting products. In the future, if such an ultra-high pressure fire hose were commercialized and applied in the field, it could contribute to securing improved fire suppression and safer exit from fires, as compared to the fire hoses currently used in the suppression of fires in skyscraper buildings and long tunnels.
