경량전철시스템은 운전자가 없는 무인으로 운행하며 각종 설비가 자동으로 제어되도록 되어있기 때문에 일상적인 고장이나 문제는 어느 정도 안전대책이 마련되겠지만 테러 또는 고의에 의해 일어나는 사고는 대비하기가 어려운 실정이다. 정거장에서의 화재발생은 많은 보고서와 기준들이 정리되어 있으나 지하 터널이 본선 구간에서의 피난을 위한 시설의 적정성 및 피난시간에 대한 연구는 부족하다. 본 연구에서 경량전철 시스템의 운전 중에 지하터널에서 발생 가능한 사고시나리오를 고려하여 화재시뮬레이션 및 피난시뮬레이션을 실시하여 비교하고, 그 결과에 따라 대안을 도출하였다.

Based on the analysis of fire escape situations in public facility, this study was intended to propose a design of emergency light suitable for fire in public facility. A video analysis was conducted to understand the evacuation situation of public facility because the fire could not be randomized due to the disaster. Through video analysis, we were able to identify inconvenience and necessary needs in avoiding fire in public facility and reflected them in the design of emergency light, etc. As a result of the design of emergency light, the wall type induction lamp had different LED layout structures to minimize the thickness of the product. Ceiling induction lamps have been supplemented for additional installation in corridors of complex structures. The results of this study are designed based on the criteria used in the manufacture of actual emergency light and we intend to explore ways to be practical through further experiment measurements and complementary steps through expert advice.

Recently, Since buildings are bigger and higher, the damage of human life can be increased by fire flame and smoke in fire. Smoke control system is necessary to decrease this damage. Therefore, Air supply pressurization smoke control system is applied to vestibule of escape stairway. NFSC requires pressure differential of 40 Pa~60 Pa, but pressure differential is over 60 Pa in the field. It is known that the cause of this over pressure differential is much leakage of damper. Over pressure differential can bad effect to escaper by pressurizing the door. Analyze the real leakage of damper by testing for identifying this problems. The result of testing, leakage is $0.090m^3/s{\sim}0.154m^3/s$. It is necessary to limit the leakage of dampers for safe of escapers.

Although fire incidents occur frequently in factory buildings, the focus has primarily been on property damage rather than human casualties. In this study, we conducted an analysis of RSET(Required Safe Egress Time) variation by examining the relocation of workbenchs using evacuation simulations. The results demonstrated that a simple change in workbench placement led to different RSET and variations in the feasibility of evacuation. Specifically, arranging workbenchs in a vertical configuration reduced travel time for workers and minimized total evacuation time. The hybrid layout of "vertical-horizontal" exhibited the shortest RSET, while the "horizontal-vertical" configuration resulted in the longest RSET. These research findings are significant as they provide practical alternatives to decrease RSET in small-scale factories where additional investments beyond essential safety equipment may pose challenges due to budget constraints. However, it is important to note that this study solely focused on comparing RSET while controlling for all other factors, without considering real-life fire simulations. Therefore, further research is necessary to integrate fire simulations and conduct comprehensive assessments of evacuation safety.

In the case of office buildings, domestic and Chinese evacuation laws were compared regarding the evacuation of horizontal and vertical buildings and evacuation to refuge safety areas. A simulation was conducted based on a refuge safety area in China. In the case of evacuating 1 floor, there was no significant difference in the flow of occupants to an ancillary room area in a domestic or Chinese building, but in China, the corridor width was narrower and the occupants have saw a long. In the case of evacuating 15 floors, the flow of occupants to an ancillary room area was different. In the case of China, it was possible for occupants to enter the ancillary room more quickly because the ancillary room area was wider than those found in domestic buildings, allowing quickly passage the ancillary room door. The results of this study found that if corridor width and ancillary room area were wider, evacuation times could be reduced.

국내의 건축물의 화재안전성 평가는 화재안전성을 고려한 공간구성, 연기의 유동, 거주자의 피난계획 및 피난성능평가, 건축물 내부에 설치된 방화설비계통의 화재안전성능평가 등을 연구하여 왔다. 그런데 이들 연구의 대부분은 건축물의 공간적 특성분석과 주거여건 등을 고려한 기초자료의 파악 및 분석 등을 국내의 여건과는 상이한 국외의 자료를 근거로 하거나 2차원적인 해석 및 평가에 그치고 있는 경향이 있다. (중략)

화재가 발생할 때 연기로부터 안전하게 피난과 소방관의 소화활동을 위해 제연설비가 설치되어 있다. 기존의 자동차압·과압 조절형 급기댐퍼는 화재층과 비화재층을 구분하지 못하므로 화재가 발생하지 않는 층에서 피난을 할 경우 화재층이 연기로부터 보호받지 못한다. 스마트 댐퍼를 적용하면 화재층과 비화재층을 구분하므로 화재층을 연기로부터 보호가 가능하다.

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 in Korea. As a preceding review of this study, the combustibles was categorized and identified their heat release rates. For validate the estimated values, modeling a single underground shop was carried out. And a numerical analysis both in case of smoke control system in operation and the system not in operation was carried out of underground space. From the viewpoint of securing the evacuation time, the results were compared in an attempt to assess the appropriateness of the fire safety criteria.
