  • This research analyzes clean room major fire prevention standard of clean Room(FM, IRI, and NFPA Code), the structure of Performance-Based Fire Safety Design(PBD) applied the korean fire industry situation. Performance-Based Fire Safety can operate effectively the performance of fire protection equipment & building design, so the fitness of fire safety system can be embodied by operating this. moreover, cost to be consume fire safety of real building can reduce and Performance-Based Fire Safety is considered to important technique in fire protection field. A fire in a clean room may cause a serious loss by spreading smoke particles. We will be investigated by using a computational fluid dynamics, for loss prevention by smoke spreading from one fire area to another for clean room and compared the Performance-Based Fire Safety Design with the prescriptive code design. The methodology of fire safety performance-based fire safety design and guarantee of many kinds design skill of fire system and developing design procedure will be very serious one in order to improve efficiency of domestic system. Therefore, This research will be contributing to secure safety of clean room and to set up the performance-based fire safety design in Korea by regulation for the performance-based fire safety design effectively.

  • Crown fire, the main propagation type of large forest fire, has caused extreme damage with the fast spread rate and the high flame intensity. In this paper, we developed the probability equation to predict the crown fires using the spatial features of topography, fuel and weather in damaged area by crown fire. Eighteen variables were collected and then classified by burn severity utilizing geographic information system and remote sensing. Crown fire ratio and logistic regression model were used to select related variables and to estimate the weights for the classes of each variables. As a results, elevation, forest type, elevation relief ratio, folded aspect, plan curvature and solar insolation were related to the crown fire propagation. The crown fire propagation probability equation may can be applied to the priority setting of fuel treatment and suppression resources allocation for forest fire.

  • Globally, the forest fires are a significant contributor of carbon dioxide and other greenhouse gases in the atmosphere. In this study, fuel load consumed by forest fire and emission of green house gases were analysed in the surface layer. For this, remaining fuel was collected and weighed with the species (Japanese red pine, deciduous) and the forest fire types (surface fire, crown fire) in the 51 forest fires. 8,361 kg/ha fuel load was consumed in deciduous forest damaged by surface fire, and 8,055 kg/ha, 12,333 kg/ha in Japanese red pine burned by surface fire and crown fire. The combustion ratios were 78, 59, and 90%, respectively. 15,856 kg/ha the green house gases such as $CO_2$, $CH_4$, $CH_4$ in deciduous forest burned by surface fire was emitted and 14,834 kg/ha, 22,709 kg/ha in Japanese red pine burned by surface fire and crown fire.

  • Goverment and enterprises have been devoting a lot of dffort in order to prevent the loss of human and property due to a large, diversified fire, explosion, global warming and disasters caused by natural phenomena. But Enterprises came forward and running in the economy priority policy for profit-seeking until now in order to meet the macro purpose of quality improvement of national life and welfare promotion in company with National growth, as a result of lax risk management have had to endure the loss of precious lives and property. According to the '2007 Survey of public safety for the activation of the safety culture' of National Emergency Management Agency [NEMA], a insensitivity of safety in our society was surveyed 'a serious level'. In this study, surveyed need of 'step-by-step fire protection safety management system builds' in order to prevent fire safety accident and improvement of safety awareness level through a systematic management and real condition estimation of not only large business that can control risk management, but also small business that has a big risk to occur accident easily according to small budget and organization.

  • Because of not accepted on escape using elevators in fire emergency has some background. In the background elevator hoistway has turn into smoke spread route in fire. The escape that used an elevator was not able to make ends meet; of the big confusion is expected that cannot control the escape adequately, and do that elevator facilities breakdown possibility by the fire water, the escaper shut in car. Therefore ban on elevator service in fire time as a general rule. Recently, a few company promote super high-rise architecture in the country, a fire disaster prevention and human life safety measures preparation for PBD(A Performance Based Fire Protection Design) are studied concretely. And there is the escape example in fire time that used an elevator in the foreign country. You must promote it so that the escape measures that used enclosed stairway and an elevator in charge of a function of the mutual supplement. The result of this research can be used for establishing the standard and regulation for using elevators in fire emergency.

  • In this study, fire and evacuation safety of environmental energy facilities using fire and evacuation simulation was examined as part of performance-oriented design. The worst-case fire scenarios in which fire-fighting facilities such as sprinkler fire extinguishing and smoke control systems are not working, and the FDS analyzes the visibility, temperature distribution, and carbon monoxide concentration distribution through FDS. The safety was examined. As a result, it was proved that evacuation could limit the visibility, temperature, and carbon monoxide concentration in a smooth range, based on the safety standards set by relevant laws. In other words, it was possible to verify the safety of fire and evacuation for environmental energy facilities where a large amount of combustibles and fires coexist.

  • Considering heat insulation and beautiful sight of construction, making use of exterior panels is increasing. Recently the exterior panels now are weak very much, and so in consequence of the weakness fire spreads rapidly. Compared with internal fire, external vertical fire spread rate goes rapidly and it is extensive in spread range, therefore it is dangerous very much. Accordingly, under present condition of poor standard of exterior panels, it is required to take measure to meet the appropriate situation. In this study, by making use of FDS(Fire Dynamic Simulation) program about external vertical fire of high rise building, fire behavior is searched by computer. It is important that realizing by computer fire modeling about external vertical fire must be included certainly in procedure of fire performance design in the future. In modeling program, FDS version 5 is available, and aluminium composite panel is applied in external panels. In this study, for realizing of actual fire condition, FDS is applied by details of fire scenarios considering influence of wind.

  • The victims of fire are increasing steadily. Fires have been occurred by arson, spontaneous combustion and various causes. As a result of that, the damages of fire got out of hand. Especially, the fires of flammable liquids are can be spreaded easily because of high calorific value and fire loads. These rapid fire spread cause the huge losses of both life and property and the malfunction of extinguishing systems. In these studies, we examined the spread pattern of surface fire on the water surface by the reappearance experiment.

  • The electronics factory fire, that occurred at 15:40 on August 21, 2018, killed nine people and injured six. This study analyzes the causes of many of the casualties from the fire, and is based on fire investigation results and so on. The findings suggest that major causes included failure of the automatic alarm system to function, failure of the emergency broadcasting system to function, the fire suddenly spreading due to polyurethane foam in a ceiling on the 4thfloor, a power outage immediately after the fire started, a sprinkler system that was not working, a delay in reporting the fire, and improper management of fire facilities by a fire safety management company.
