Facilities used by senior citizens, infants, and disabled people have characteristics that make it difficult to escape on their own or require a lot of evacuation time. Therefore, to ensure safety in case of fire, clear measures for securing safety of facilities, fire response methods, and training are required in accordance with the regulations. In case of postnatal care center facilities, newborn babies and mothers reside 24 hours a day, and as they are located in high-rise and multi-use facilities, measures for fire safety are necessary, but the domestic manual lacks. Accordingly, a field survey for security of the manual revealed that the establishment of awareness and facilities on temporary waiting areas and smoke control, which are easy for evacuation and fire safety, was a problem.

This study is intended to evaluate the characteristics of smoke spreading and the appropriateness of evacuation time extended by operation of smoke control system during fire within the underground space of the building structured in compliance with the smoke control system performance criteria from the local fire safety standard, which has been currently applied to the buildings in Korea. Using the heat release per unit weight of the combustibles, a numerical analysis both in case of smoke control system in operation and the system not in operation was carried out at the several different shopping malls. From the viewpoint of securing the evacuation time, the results were compared in an attempt to assess the appropriateness of the fire safety criteria.

In this paper, various hazard factors are reviewed on the train fire accident in railway tunnel and subway. In case studies of systematic risk evaluation on the tunnel fire accident, we have learned the critical fire safety points for accident prevention and damage reduction such as fire-endurance of infrastructure, mortality of heat & toxic smoke, emergency situation control and management of escape requirements etc.. These hazard analysis study will contribute for improving the railway fire-safety and establishing the long-tenn safety management plan.

Recently the increase of natural disaster and man-made disaster, newly emerging infectious diseases and bioterrorism attack changed the world in many aspects. So the Ministry of Health and Welfare and other related agencies are trying to solve the problems with disasters. We discussed these problems in the following eleven categories. (1) emergency medicine (2) communicable disease control, (3) food safety control, (4) public facilities safety, (5) social welfare facilities safety, (6) bioterrorism control, (7) geriatric health care, (8) insurance support, (9) overseas disaster victim support, (10) national organization protection, (11) fire fighter safety in forest fire. Through the reviews on the various kinds of disaster, we proposed the disaster control measure for the near future.

Fire tests were conducted on cables using fire-retardant paint employed in nuclear power plants that transmit electrical power, control and instrument signals. The failure criteria of various power and control cables coated with fire retardant coating at three different coating thicknesses (~0.5 mm, 1.0 mm & 1.5 mm) were studied under direct flame test using Container Fire Test Facility (CFTF) based on standard tests for bare cables. A direct flame fire test was conducted for 10 min with an LPG ribbon burner rated at ten by fixing the cable samples in a vertical cable track. Inner sheath temperature was measured until ambient conditions were achieved by natural convection. The cables are visually evaluated for damage and the mass loss percentage. Cable functionality is ascertained by checking for electrical continuity for each sample. The thickness of cable coating on fire exposure is also studied by comparing the transient variation of inner sheath temperature along the Cable length. This study also evaluated the adequacy of fire-retardant coating on cables used for safety-critical equipment in nuclear power plants.

본 연구에서는 국내 화재 안전 기준 중 제연설비의 성능기준에 의해 지하 공간 건축물이 준공된 후 임의의 지점에서 화재가 발생했을 경우를 모델링하여 연기 확산 현상을 분석하고 제연 설비의 작동에 의한 재실자의 피난시간 연장과의 적정성을 검토하는 것이 목적이다. 본 연구의 선행연구에서는 가연물의 종류와 발열량을 추정하였으며 추정 값의 검토를 위하여 임의의 단일지하상가를 모델링하여 검증하였다. 그리고 지하상가의 제연설비가 작동될 경우와 작동되지 않을 경우에 대한 수치해석 결과를 비교하였으며 재실자의 피난시간을 확보하는 관점에서 화재 안전 기준에 대한 적정성을 검토하였다.

Fire protection is one of important issues to ensure safety and reduce risks of nuclear power plants (NPPs). While robust programs to shut down commercial reactors in any fires have been successfully maintained, the concept and associated regulatory requirements are constantly changing or strengthening by lessons learned from operating experiences and information all over the world. As part of this context, it is necessary not only to establish specific fire hazard assessment methods reflecting the characteristics of research reactors and educational reactors but also to make decisions based on advancement encompassing numerical analyses and experiments. The objectives of this study are to address fire simulation in the control room of an educational reactor and to discuss integrity of digital console in charge of main operation as well as analysis results through comparison. Three electrical fire scenarios were postulated and twenty-four thermal analyses were carried out taking into account two turbulence models, two cable materials and two ventilation conditions. Twelve supplementary thermal analyses and six subsequent structural analyses were also conducted for further examination on the temperature and heat flux of cable and von Mises stress of digital console, respectively. As consequences, effects of each parameter were quantified in detail and future applicability was briefly discussed. On the whole, higher profiles were obtained when Deardorff turbulence model was employed or polyvinyl chloride material and larger ventilation condition were considered. All the maximum values considered in this study met the allowable criteria so that safety action seems available by sustained integrity of the cable linked to digital console within operators' reaction time of 300 s.

지진 시 실내안전 대책은 가구의 전도 낙하로 인한 재해를 대비하기 위한 방재대책으로 매우 중요하다. 그러나 많은 사람들은 가구 고정과 같은 실내안전 대책에 대해서 모르고 있으며, 교육도 받지 않고 있다. 그러므로 본 연구에서는 스마트폰을 사용하는 사람들에게 계몽 및 교육을 목적으로 스마트폰용 어플리케이션을 시험 개발하였다. 이 어플리케이션을 통하여 거주자, 가구점 종사자, 이사 종사자, 건축업자 등이 실내안전대책에 대해서 이해할 수 있을 것으로 기대한다.

According to building law, there are only regulations on the fire prevention compartments that can perform the function of partial smoke compartment, but the building law management of the smoke compartment for effective smoke diffusion prevention and control is not possible. The lack of control on the smoke compartment such as leakage rate on the penetrating part, and the lack of leakage rate in the design of smoke control of fire safety law resulted in the absence of fundamental safety technology. Therefore, this study seeks to find solutions to domestic problems after reviewing relevant domestic laws and regulations.
