화재가 발생했을 때 많은 사람이 연기에 질식하여 사망하는 피해가 거의 해마다 일어나고 있다. 특히 올해 2월18일 190여명이 사망한 대구 지하철 중앙로역 화재참사에서는 다량의 유독성 가스를 효과적으로 배출하지 못해 더 많은 사망자가 발생하였다. 당시 지하철역에는 화재가 발생하면 환기용 배기장치가 급기장치로 전환되는 급기방식의 제연설비가 설치되어 있었고, 시계 불량으로 피난 표지판과 유도등이 잘 보이지 않은 것으로 밝혀졌다.(중략)

K 문화센터는 공연 및 전시를 위한 고품격 문화 시설로서 주요 시설인 공연장은 규모 및 용도에 따라 오페라 극장, 콘서트홀, 실험극장으로 구분되어 있다. 공연장은 타 공간에 비해 높은 정숙도와 쾌적한 내부 환경, 피난 계획 등을 필요로 하기 때문에, 이를 만족하기 위해서는 실의 특성에 적합한 공조 설비, 방음.방진 및 방재 설비 등이 뒷받침되어야 한다. 따라서 본 설계사례에서는 최고 수준의 공연장 계획에 적합하도록 각 분야별로 적용된 시율레 이션 기법 및 신공법과 함께 주요 기계설비 계획에 대해 소개하고자 한다.

고충건물 피난경로의 제연시스템은 일반적으로 급기가압방식이 널리 쓰인다. 그러나 국내에서 널리 쓰이는 부속실 단독 가압방식은 공간용적이 너무 작아 차압을 형성하고 유지하는 문제와 방연풍속을 형성하는 문제 사이에 늘 불균형이 존재한다. 또한 거실 출입문을 여닫는 데 지장이 없는 차압 하에서도 계단실 출입문은 차압에 밀려 제대로 닫히지 않는 경우가 있을 수 있다. 이런 측면을 역학적으로 검토하고, 과압 해소방식을 제안한다.

This study of the vestibule of pressurizing smoke control system installed in domestic high-rise buildings for evacuation in case of fire, when the door is open to forming characteristics of the air flow was analyzed using fire dynamics simulator and analyzed of variance. Vestibule which is compartment of the design condition, air flow in the exhaust damper was formed severe turbulence confirming preceding research. The door position is in the range of formed vortex, unsteady flow of air occurs at the point that the door could be confirmed. According to the NFSC 501A, door to symmetrically separate the average of 10 points or more as measured from the average of wind speed to do is based. Under these conditions, it is difficult to measure the characteristics of the upper air flow of upper points. so measuring points are subdivided by more than 64 points method presented in TAB because severe deviation of wind speed.

Purpose: The purpose of this study is to present an evacuation performance analysis model that can derive vulnerable evacuation spaces with considering the movement behavior as per the elderly groups in the event of a fire in a geriatric hospital. Methods: The evacuation characteristics of geriatric hospital users were investigated through the review of precedent studies. First, the occupant conditions and the evacuation scenario were set to analyze a study target hospital. Then, the evacuation simulation was carried out considering the group types and the density of each group. Finally, an evacuation performance analysis model according to the group type was presented based on the simulation results. Results: The results of this study are as follows: (1) The evacuation performance according to the group type is to be clarified through the suggested study model. (2) It is necessary to secure a ramp or an emergency elevator to distribute the evacuation personnel at the design stage because congestion occurs due to collisions between evacuees on the stairs and delays the evacuation time. (3) It is necessary to consider the evacuation stairs and openings of sufficient size by analyzing the frequency of congestion occurrence and the escape routes of occupants in advance to identify the space where the evacuation flow overlaps. Implications: It is expected that the study result is to be used as primary data for studies that consider the elderly and clustering evacuation behavior in the event of a fire in a geriatric hospital.

By analyzing the operation status of fire safety management of small construction site workers, deriving problems, and suggesting improvement measures, this study was conducted to present practical basic data for their efficient use in the future, and the following conclusions were drawn. First, it was analyzed that small construction site workers are elderly in the age group of construction workers, have short construction skills, most of the jobs are working in the construction industry, and the employment type is non-regular workers. Second, the fire safety management improvement plan of small construction site workers is systematized, fire safety manager is deployed to manage fire risk, fire escape routes and emergency warning facilities are provided to inform all workers at the construction site. In addition, measures to reduce industrial accidents are needed through realistic evacuation training, fire VR training, and interesting educational programs.

화재감지 및 경보시스템의 설계 목표는 화재발생 초기 단계에서 화재징후를 발견, 피난의 개시를 신속하게 통수하는 것이다. 화재감지기는 다양한 건물 및 환경에 설치되기 때문에 주위 온도 및 가연물의 종류 등 환경적 측면을 심층적으로 고려하지 않으면 적절하게 감지하지 못하는 경우가 발생할 수 있다. 즉, 가연물 종류 등을 고려한 설계에 따라 설치된 화재감지기는 화재시 설계치 대로 조기에 화재를 감지하여 화재 예방 및 화재로 인한 피해를 최소화할 수 있는 것이다. 본 논문은 화재시 조기에 화재를 감지기하여 건축물내 인명피난을 목적으로 설치되는 화재감지기의 응답특성을 분석한 연구이다. 화재감지기의 응답특성을 분석하기 위하여 다양한 가연물을 발생시키고 화재감지기 종류별로 설치한 다음 각 화재감지기의 응답특성을 분석하였다. 그 결과 정온식 열감지기는 열방출률이 적은 화재를 조기에 감지하는 것에 적합하지 않은 것으로 나타났다. 광전식 연기감지기는 회색 계통의 목재류 화재성상에서 응답특성이 떨어졌고, 동일한 공간에서 화원의 수평거리와 동작시간이 비례한다고 볼 수 없었다.

Multiplex movie cinemas are cultural spaces where an indefinite number of people from a variety of classes and ages can enjoy movies, food, and leisure all together in one place at the same time. Those facilities which a great number of people use together like multiplex movie theaters are relatively vulnerable to fire safety, compared with other facilities to protect from fire. Considering the special nature and vulnerability of multiplex movie theaters from a fire safety standpoint, this study aims to seek measures to acquire fire safety performance of the specific facilities by selecting exemplary models of local multiplex movie theaters, performing fire and evacuation simulations for them, and reviewing and analyzing their present problems in evacuation safety as well as the relevant regulations of many countries.
