  • In this study, real fire tests were performed on representative combustibles of residential facilities to analyze the fire behavior and combustion characteristics in a small residential space. The considered combustibles were a sofa, a combination of a desk and a chair, and a combination of a mattress and an electric mat. A compartment space fire test was performed using the room corner test equipment prescribed in the KS F ISO 9705 specification. Three real fire tests were conducted by placing the combustible material inside a small compartment with insulation and finishing materials and by igniting the combustible material. Results showed that the peak heat release rate and peak smoke production rate occurred in the combination of the mattress and electric mat. Furthermore, from the result of the fire rate analysis, it was estimated that the fire risk of the mattress and electric mat combination was the highest, followed by the sofa and thedesk and chair combination.

  • The recent fire incident in an elementary school of Chonan city causes the media focus on the fire safety of residential container buildings. In this study, real fire tests were conducted in this kind of buildings. Combustion products including $O_2$, $CO_2$, CO, $NO_x,$, $SO_x$, HCI, HCN were measured, in order to investigate the hazard-reduction effects of employing gas mask protected with filter during the fire emergency of residential container buildings. According to the test results, whether or not employing the filter showed a sheer difference in the toxicity of the fire-induced gases, and then the importance of wearing a gas mask was evidently demonstrated.

  • 경제의 성장과 산업이 발달함에 따라 건축물의 구조나 형태가 다양화되고 있다. 최근에 건설되는 건축물은 과거에 비하여 고층화, 대형화되고 있다. 그 결과, 보다 많은 사람들이 건물을 이용하고 건물 내의 상존 가연물의 양도 증가하였다. 가연물에 대한 연소특성 파악 및 적절한 방재계획을 수립하지 않는 다면 많은 인명과 재산의 손실이 예상된다. 본 연구에서는, 주택내 가연물의 연소특성을 파악하기 위하여 실험이 실시되었다. 가연물로는 소파, 침대, 목재가 사용되었다. 열방출률, 연소가스의 농도, 실내 온도분포 등을 측정하였으며 각 가연물의 연소특성 등을 파악하였다. 각 가연물에 대한 최대 열방출률 값이 소파 1.9MW, 침대 650kW를 나타내었다.

  • Recently, The Building has became high rising and large scaling according to development of economy in domestic and other country, also the building has increased a variety of functions of insulation for warmth. and it has a symbol of economic growth, but it has risk factor for disasters such as fire. this hazards include not only general building but also residential building. Recently, Grenfell Fire that occurred in England has increased in combustion to the 24th floor of the 1st floor for 1 hour. it resulted in 80 deaths and 79 missing persons. In this study we suggest basic data of residential building for fire safety design related to domestic environment to analyze the problem of Grenfell Tower.

  • The present study aims to evaluate the characteristics of atmospheric polycyclic aromatic hydrocarbons (PAHs) pollution in roadside and residential areas of two Korean metropolitan cities (Seoul and Incheon) and a background area (Seokmolee). This purpose was established by analyzing temporal and spacial concentration distribution of total and 7 individual PAHs, which were extracted from ambient particulate matters, and by utilizing a multivariate statistical method (principal component analysis, PCA) for the qualitative determination of potential PAH sources. Target PAHs included benzo(a)anthracene (BaA), benzo(a)pyrene (BaP), benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF), chrysene (Chr), dibenzo(a,h)anthracene (DahA), and indeno(1,2,3-cd)pyrene (IcdP). For all surveyed sites, the concentrations of total PAHs were higher in winter season than in other seasons. However, the concentrations of individual PAHs varied with surveyed sites. In both residential and roadside sites of Seoul and Incheon, BbF revealed the highest atmospheric levels. For all 7 target PAHs, the ambient concentrations were higher in Seoul and Incheon than in a background area (Seokmolee). In both residential and roadside areas, the concentrations of 4 target PAHs (BaA, BbF, BkF, DahA) were higher in Incheon than in Seoul. However, both the residential and roadside Chr concentrations were comparable in Seoul and Incheon. In addition, the residential IcdP concentrations were higher in Incheon than in Seoul, whereas the roadside concentrations were higher in Seoul. The roadside and residential BaP concentrations exhibited the reverse result to the IcdP concentrations. An PCA analysis suggested that atmospheric PAHs in both residential and roadside areas would be due to combined effects of several potential sources such as gasoline- and diesel-fueled vehicles, coal/oil combustion, and waste incineration.

  • 60년대 이후 우리나라에 새로운 주거양식으로 정착된 아파트내 설비의 일부였던 쓰레기 투입구(Dust Chute)는 여러 사회적인 논의를 거쳐 폐쇄되었고, 이제는 신도시에서 조차도 찾아볼 수 없는 낡은 유물이 되고 말았다. 현재는 주택 옥외공간에 별도의 집하장소를 만들어 수거해가는 방식으로 대응하고 있는데, 그럴수밖에 없었던 주된 이유는 분리수거가 제대로 이뤄지지 않은데 기인한 것으로 분석된다. 95년초부터 전국적으로 실시된 쓰레기종량제는 우리나라의 쓰레기 처리 분야에 있어 생활쓰레기의 분리수거 및 재활용을 가능케하는 제도로 자리잡고 있다. 인간들은 또 그린라운드 시대에 걸맞는 주거환경의 질을 추구하고 있다. 이러한 사회적 변화에 대응한 여러 노력이 쓰레기 수거운반 분야에서도 이뤄질 수 있다고 본다. 이미 택지개발 등으로 새로 조성되는 주거단지에는 지역난방시스템과 쓰레기소각장, 공동구 등이 도입 활용되고 있으며, 바로 이들 시설과도 밀접한 연관성이 있는 각국의 쓰레기 수거운반 방식을 비교하고, 선진 각국의 신도시와 주요 대형시설에 도입 활용되고 있는 방식인 관로내 공기를 이용한 쓰레기 수거운반 시스템(Pneumatic Waste Collection System)의 적용사례 및 그의 실용성에 대하여 연구하기로 한다.

  • This study was designed to investigate the characteristics of atmospheric concentrations of toxic volatile organic compounds (VOCs) in Korea. Target compounds included 1,3-butadiene, aromatics such as BTEX, and a number of carbonyl compounds. In this paper, as the second part of the study, the seasonal and locational concentrations of atmospheric VOCs were evaluated. Sampling was conducted seasonally at seven sampling sites. each of them representing a large urban area (commercial and residential), a small urban area (commercial and residential), an industrial area (a site within the complex and a residential), and a background place in Korea. In general, higher concentrations were found in the petro-chemical industrial site than other sites, while VOCs measured in commercial (heavy -traffic) sites were higher than residential sites. Seasonality of VOCs concentrations were not so much clear as other combustion related pollutants such as sulfur dioxide, indicating that the VOCs are emitted from a variety of sources, not only vehicle exhaust and point sources but fugitive emissions. Except the industrial site, the concentrations of VOCs measured in this study do not reveal any serious pollution status, since the levels did not exceed any existing ambient standards in the U.K. and/or Japan. However, the increasing number of petrol -powered vehicles and the rapid industrialization in Korea may result in the increased levels of VOCs concentrations in many large urban areas in the near future, if there is no appropriate programme implemented for the control of these compounds.
