국내에서는 철도차량의 화재안전성능을 향상시키기 위해 성능평가를 적용하기 위한 연구가 진행되고 있다. 철도차량에서의 화재 시 피난은 여러 가지 시나리오들이 존재하며, 이중 하나가 터널내부에서 정전이 되어 무조명상태가 되는 것이다. 철도차량은 물리적 공간적 환경이 건축물과 차이가 있다. 또한 문화적 인종적 차이로 인해 외국의 데이터를 바로 적용하는 것도 바람직한 일은 아니다. 그러므로 시나리오를 분석하기 위해 필요한 데이터는 실험을 통해 확보해야할 필요성이 있는 것이다. 무조명 상태에서의 피난인의 행태와 이동속도의 차이 등을 분석하기 위해 실험을 수행하고 그 결과를 분석해 보았다.

국내 건축물들이 다양한 변모를 보이면서 화재안전을 위한 성능설계가 도입되고, 화재 영향평가제도와 화재위험성평가제도가 시행되고 있지만 이러한 방재관련 특별법에 대한 방법론이 미비한 실정이다. 따라서 본 고에서는 국내보다 앞서 성능설계를 도입하여 시행하고 있는 일본의 동경소방청 화재피난시뮬레이션(FEA)을 국내 성능설계의 방법론으로 적용시키기 위하여 FEA를 중심으로 국내에서 범용적으로 사용되고 있는 SIMULEX와 EXDOUS를 활용하여 사례분석을 통한 각 시뮬레이션의 특징에 따른 차이점을 분석하고 FEA의 한국 적용방안에 대한 기초자료로 제공하고자 한다.

본 연구에서는 특별피난계단의 전실에 설치되는 부속실제연설비가 화재 시 발생한 연기가 부속실 내로 역류하지 않는 급기댐퍼의 적정한 설치위치를 알아보고자 하였으며, 이를 확인하기 위하여 FDS(Fire Dynamics Simulator)을 사용 하였다. 시뮬레이션 Case 총 15가지로 구분하고, 방연풍속은 총 64개의 지점에서 측정하는 시뮬레이션을 수행하였다. 시뮬레이션 결과 출입문 상부 및 하부에서 역 기류가 발행하는 Case가 있었으며, 대부분 출입문 하부에서의 연기 유입이 예상되는 경우가 많았다. 방연풍속은 측정 포인트 64점에서 관련기준에 단 한 곳도 미달하지 않고 만족하는 경우는 총 단 4가지 Case로서 매우 제한적인 것을 알 수 있었다. 그만큼 급기댐퍼의 위치 및 급기방향에 따라 부속실 제연설비의 성능이 다양하게 나타날 수 있다는 것이다. 본 연구를 바탕으로 앞으로 실물실험을 통하여 구체적인 자료가 입증되길 바라고, 더불어 부속실 제연설비의 성능을 개선하는 데 있어 도움이 되었으면 한다.

The object of this study is to evaluate whether the means of egress of Jechon Sports Center and Miryang Sejong Hospital, where massive fire human casualties occurred in 2017 and 2018 respectively, comply with NFPA 101(Life Safety Code), and to suggest the need for supplementation of domestic means of egress regulations. The study evaluated the number and arrangement of the means of egress, travel distance, common path of travel, dead end and discharge from exit for each building by applying the means of egress regulations of NFPA 101. As a result of the evaluation through NFPA 101, the travel distance was appropriate, but some of the other items except for the travel distance did not meet NFPA 101. The regulations that need to be supplemented are 1)occupant load calculation 2)egress capacity calculation 3)continuous concept of means of egress 4)concept of common path of travel. It is especially necessary to revise the requirement for fire door of the evacuation floor(normal 1^st floor) of the stairwell in case of below the five story building.

In this study, risk categorized five safety management elements(equipment and structure, evacuation, lifesaving and fire extinguishing, performance based fire safety plan, operations management) were classified in order to establish safety system of underground space. Using classified safety management elements, assessment of fire hazard was performed. After calculating the grade of evaluation categories, assessment of fire hazard was suggested. The three grades of evaluation categories are classified as to importance and four criteria of evaluation are classified as to check result based on subdivisions.

The university dormitory have various functions and large floating population so in the occurrence of fire, there could be heavy casualties. Also, when university dormitory is located far from fire station, it is difficult to fire brigade arrives on Golden Time. Therefore, university dormitory need response capabilities for fire by itself. This study conducted a simulation experiment on those residing in K University dormitory in Gangwon-do, where site proximity is unfavorable, to observe evacuation characteristics of the occupants. As a result, evacuation is delayed due to a lack of evacuation routes and administrator, some students lack of fire awareness. Also fire brigade didn't arrive on Golden Time. Therefore, to resolve problems it is proposed that a student fire volunteer department.

Integral fire shutters are installed indiscriminately, regardless of evacuation. There is always the risk of an accident because integral shutters are applied mainly to corridors, passages, and stairs of schools This study evaluated the problem of integral shutter's entrance, evacuation, construction management, and maintenance control through a fire shutter accident case, including present condition of fire shutter installed at school of Okgil, Bucheon and Dongtan, Hwaseong. The results suggest that emergency lighting or signs for passage be set up to check location of entrance easily and install obstruction sensors at fire shutter to reduce life damage. In addition, the number of efficiency tests of fire shutters should be increased by running a trial test monthly or weekly to maintain the performance of fire shutter. Schools need to install a fire shutter- applied sprinkler at the entire floor.

Purpose: Fires that occur during construction are infrequent, but cause great damage. Recently, with the growth of the logistics and distribution industry, the number of construction sites for new logistics warehouses is increasing, so it was selected as a research subject and research was conducted to reduce accidents at construction sites through the development of a fire risk assessment tool to quantitatively approach fire prevention. Method: A comprehensive fire risk assessment tool was accumulated by classifying the work in progress, classifying combustibles and ignition sources by grade, excluding air (oxygen), which is difficult to control, and additionally substituting evacuation safety. Result: Using the developed and proposed fire risk evaluation tool, excavation work with low fire risk, facility construction with medium fire risk, and finishing work with high fire risk were sampled to derive the result (CGI). Conclusion: In this study, it was possible to establish specific preventive measures and evaluate evacuation safety by controlling physical conditions (combustibles) and energy conditions (ignition sources) according to the risk assessment by developing a tool that can evaluate the risk of 14fire occurrence at construction sites. It is expected that in the future, through the application of the fire risk evaluation tool at construction sites, it will be provided as a criterion for establishing a process plan that can reduce risk and evaluating the adaptability of firefighting equipment.14

In correctional facilities with majority of occupants in custody, the safe evacuation guide without getaway accidents should be very important due to complexity in escape paths. Fire causes are various in correctional facilities, for example, arson fire is a major cause in mental treatment facilities, however, old facilities or carelessness of flammable materials consist of fire causes in jail facilities. Both types of correctional facilities are the same in terms of many casualties from the fire cases. The thesis focus on escape paths and evacuation guide plans on the basis of analysis on fire cases and structural vulnerability, and then an electronic unlocking system is concededly installed for safe evacuation of occupants in custody without getaway accidents. Especially, the effect of the electronic unlocking system is going to be analyzed on the basis of RSET (required safe egress time) in order to realize for the occupants to evacuate safely to the front yard in case of emergency. In conclusion, if electronic security allowed system with USN (Ubiquitous Sensor Networks) technology should be installed in multi-storey correctional buildings, it is proposed that the occupants in custody might be a guided safely without getaway trials.
