  • When the fire occurred in building, the fire-resistance-structure has to be constructed to prevent collapse of building and to have a time for evacuation of peoples. because of the features of the fireresistance test is similar with real scale, there is no way to confirm quality of fire-resistive-structure in building construction site. Therefore the purpose of this study, a study by spectroscopic analysis using near-infrared spectroscopy (NIR), is to suggest of useful and scientific testing-methods in building construction site by identification-analysis-study for fire resistive paint.

  • 스티로폼샌드위치패널은 건식공법의 시공편리성, 경제적인 공사비용, 뛰어난 단열성능으로 공장이나 창고건축물을 중심으로 많이 사용되고 있다. 그러나 스티로폼의 여러 가지 장점에도 불구하고 화재에 취약한 단점이 있어 최근 난연성능이 보완된 난연스티로폼패널의 사용이 증가하고 있다. 최근 건축현장에서, 가짜 난연스티로폼패널 사용이 문제되고 있으나 난연성능의 현장 확인에 어려움이 있고 콘칼로리미터 등의 난연성능평가에 시간과 비용이 소요된다. 본 연구에서는 콘칼로리미터를 통해 난연성능이 확보된 난연 스티로폼패널의 심재와 일반스티로폼패널 심재를 대상으로 근-적외선 분광분석을 수행하여 난연성능의 유무에 따라 상이하게 나타나는 고유스펙트럼 흡수를 측정하였다. 각 제품마다 측정된 고유스펙트럼은 통계처리를 통하여 난연스티로폼의 진위여부를 현장에서 구별할 수 있음을 확인하였으며, 비용효율이 높은 현장평가방법으로의 적용이 가능함을 실험을 통해 입증하였다.

  • A self-regulating heating cable is an electrical heating element by flowing an electric current between parallel conductors filled with an extruded semi-conductive polymer. Self-regulating heating cables are used mainly for frost protection purposes because the construction is convenient and the price is low. On the other hand, structural problems with imperfections of the insulation can cause a fire despite their usefulness. This paper deduced a direct method to derive the cause by investigating the scene of a fire due to a self-regulating heating cable and analyzed the basic problem using fault tree analysis. In this paper, the actual fire scene was a cold storage warehouse, and fire investigation was conducted. After investigating the fire scene and fault tree analysis, the cause of the fire could be attributed to dielectric breakdown of the self-regulating heating cable. This paper could be utilized in the fire safety activities and similar fire investigations.

  • Objectives: Firefighters are known to be exposed to a variety of toxic substances, but little information is available on the exposure profile of firefighting activities. The aims of this study were to conduct exposure monitoring of toxic chemicals at fire scenes, to compare the concentrations of respective chemicals among firefighting tasks, and to assess the main factors influencing the concentrations of chemicals. Methods: Researchers performed sampling at firefighting scenes during four weeks in 2013. At the scene, we collected samples based on firefighters' own activities and examined the situation and scale of the accident. Collected samples were classified into three categories, including fire extinguishing and overhaul, and were analyzed in the laboratory according to respective analysis methods. Results: A total of fourteen fire activity events were surveyed: five fire extinguishing, six overhaul, and three fire investigations. Although no substance exceeded the ACGIH TLV, PAHs were detected in every sample. Naphthalene ranged from 0.24 to 279.13 mg/㎥ (median 49.6 mg/㎥) and benzo(a)pyrene was detected in one overhaul case at 10.85 ㎍/㎥. Benzene (0.01-12.2 ppm) was detected in every task and exceeded the ACGIH TLV. No significant difference in concentrations between tasks was shown. Conclusions: These results indicate that all firefighting tasks generated various hazardous combustion products, including possible carcinogens.

  • 최근 빈번하게 발생하고 있는 사우나 등의 열을 방사하는 도크내에서 발생하는 화재사고는 다중이용업소를 이용하는 불특정한 사람들의 생명을 위협하고 있는 수준에 도달하고 있다. 특히 이런 시설의 화재는 화재발생 후에 소방대에 의한 진압에만 치중하고 있어 향후 계속하여 화재가 발생할 우려가 큼에도 불구하고 착화원인을 규명하는데 소홀히 하고있다. 특히 현장감식에 의한 육안조사만을 실시하여 화재원인을 추정하거나 설정하는 경우가 대부분이라 근본적인 대책을 세우지 못하고 있다. 따라서 본 연구에서는 육안조사 등에 의하여 설정한 착화원인을 과학적인 분석법 즉, EU국가에서 널리 사용하는 CFD(컴퓨터수치해석)시뮬레이션 S/W를 사용하여 연소모델링에 의한 검증조사기법을 적용하여 원인을 검증하는데 사용하여 국내화재조사기술의 과학화를 시도하였다.

  • This study aimed to develop a prehospital protocol on CPR to patients with nontraumatic cardiac arrest for emergency medical technicians. For the purpose, we prepared a protocol based on preliminary items and demonstrated its validity to confirm a final protocol from March 1, 2007- August 30. 2008. The practical CPR protocol on cardiac arrest victims can be used as means to support quick and exact decision-making on CPR, which will contribute to enhancement of emergency medical services.
