When the fire occur in the deeply underground subway station, the difficulties of passenger evacuation are expected because of many stairs to the exit. In this study, SOONGSIL-University station (7 line, 47m depth) is the one of the deepest subway stations of the each line in the Seoul metro. The numerical computational-simulation was performed for the fire driven flow in the subway station. Hot and smoke flow was analyzed from the simulation results. The proper plan of evacuation against fire was considered through the results. The fire driven flow was simulated using FDS code in which LES method was applied. The Heat Release Rate was 10MW and the ultrafast model was applied for the growing model of the fire source. The proper mesh size was determined from the characteristic length of fire size. The parallel computational method was employed to compute the flow and heat eqn's in the meshes, which are about 10,000,000, with 6cpu of the linux clustering machine.

This study explores fire prevention measures for single-person households on the phenomenon of an increase in single-person households due to changes in the family structure due to low birthrate and aging population, full marriage, non-marriage, separation, bereavement, and returning to farming villages, and increased flexibility in the labor market. The factor that affects the fire of single-person households is the residential environment problem at the structural level. In terms of behavior, there is an increase in fire occurrence due to the rearing of companion animals. In order to prevent fires in single-person households, safety regulations without exceptions are needed to improve the residential environment at the structural level. At the behavioral level, it is necessary to expand the prevention and safety guidance of related organizations. In addition, as a measure to prevent fire caused by companion animals, manufacturers of electric ranges should develop safety devices to prevent fires caused by companion animals, such as an automatic power-off device or power supply using a timer. It can also be an important means to create and distribute promotional videos of measures necessary to safely raise companion animals, or to develop and distribute disaster preparedness programs implemented in virtual reality.

Unlike cases of fire on land where experienced fireman and various fire fighting equipment are present, onboard fires need to be independently extinguished, making it a complex process. The primal objective of getting quick control of a fire is to prevent casualties which generally occur from inhalation of toxic fumes rather than the fire itself. However, if for some inevitable reason the fire cannot be contained, everyone in that particular area must evacuate to avoid any possible casualties. In this research, through a simulation of the CFD, we will observe the soot density concentration which affects evacuation within an onboard fire in relation to the possible evacuation time to conclude a time zone for a safe exit.

The purpose of this study is to understand the risk of chemical product, Styrene Monomer(SM), shipped in a vessel. SM is harmful chemical product which can make injury, explosion and/or fire in a vessel. The understand of SM risk is very important to protect seafarer's body and vessel safety. This research can be expected that the understanding of SM risk by a seafarer's to prevent accidents by SM explosion and/or fire.

A fire shutter is installed to prevent the movement of fire or smoke when a fire occurs inside a building. Fire shutters have access doors for passengers. On the other hand, the present fire shutter door display regulation is only required to be displayed in a different color from the surroundings. Hence, the risk of people not being able to recognize the door of the fire shutter is quite high, and the danger increases further in a smoke situation. Therefore, this study attempted to find a way to mark a fire shutter door that can be recognized even when smoke is spreading. First, a preliminary questionnaire was used to draw three factors to mark the fire shutter door (sign, door background, and edge). The experiment type was set by combining 5 colors for the three derived factors. The experiment was conducted on a total of 122 male and female participants. The results showed that a yellow background, red sign, and red edge have the highest awareness in a normal visual field without smoke. This was also the same in the field of view in the case of a fire with smoke, but the red background, yellow sign, and yellow edge were most noticeable in the case of dark smoke.

In the event of fire, it is necessary to put out the fire within a golden time to minimize personal and property damages. To this end, it is necessary for fire engines to arrive at the site quickly. This study established a fire engine travel time estimation model to secure the golden time by identifying road and environmental factors that influence fire engine travel time in the case of fire by examining data on fire occurrence with GIS DB. The study model for the estimation of fire engine travel time (model 1) covers variables by applying correlation analysis and regression analysis with dummy variables and predicts travel time for different types of places where fire may occur (models 2, 3, 4). Analysis results showed that 17 siginificant independent variables are derived in model 1 and the fire engine travel time differs depending on the types of places where fire occurs. Key variables(travel distance, number of lane, type of road) that are included commonly in the 4 models were identified. Variables identified in this study can be utilized as indicators for research related to travel time of emergency vehicles and contribute to securing the golden time for emergency vehicles.

오는 4월 13일은 임시정부수립기념일이다. 이에 상하이의 인쇄사에서 잠시 근무했던 이봉창 의사와 독립선언서를 인쇄했던 보성사에 대해 알아본다. 이봉창 선생은 1932년 1월 8일 일본제국주의의 심장부인 도쿄에서 삼엄한 경호를 받으며 궁성으로 돌아가던 일왕에게 수류탄을 투척, 일본인의 간담을 서늘케 하고 전 세계 피압박 민족에게 큰 충격을 준 인물이다. 이 선생이 터뜨린 한발의 수류탄은 당시 침체일로에 있던 상해임시정부에 새로운 전기를 마련해 주었다. 정부는 지난 62년 선생의 장거를 기리어 건국훈장 대통령장을 추서했다. 보성사터 기념비는 지금의 조계사 좌측 수송소공원에 있는데, 천도교에서 경영하던 인쇄사로 보성학교 뒷마당에 자리 잡고 있었다. 1919년 당신 최남선이 경영하던 신문관과 함께 최대 인쇄사로 꼽혔다. 보성사는 1919년 6월 28일 일본의 방화로 추정되는 화재로 전소됐다.

가연성 분진이 존재하는 곳에서는 업종과 취급상태를 불구하고 분진에 의한 화재 및 폭발의 가능성이 존재하며, 폭발이 발생하면 작업자 뿐만 아니라 주위에 큰 피해를 입힐 수 있는 잠재적 위험성을 가지고 있다. 분진에 의한 화재ㆍ폭발사고 사례를 보면 탱크, 혼합기, 사일로, 집진기 둥의 시설에서 알루미늄, 마그네슘 등의 금속류와 플라스틱, 프탈산 등의 화학제품류 및 합성수지류, 고무ㆍ천연수지류, 농산물 섬유류, 목분류 등의 가연성 분진에 의한 다종다양한 중대 재해가 발생하였다1). 따라서 이들 분진을 취급하고 있는 산업현장에서의 화재ㆍ폭발사고를 방지하기 위해서는 분진폭발에 대한 잠재적 위험성을 파악하는 것이 대단히 중요하다.
