  • The recent fire incident in an elementary school of Chonan city causes the media focus on the fire safety of residential container buildings. In this study, real fire tests were conducted in this kind of buildings. Combustion products including $O_2$, $CO_2$, CO, $NO_x,$, $SO_x$, HCI, HCN were measured, in order to investigate the hazard-reduction effects of employing gas mask protected with filter during the fire emergency of residential container buildings. According to the test results, whether or not employing the filter showed a sheer difference in the toxicity of the fire-induced gases, and then the importance of wearing a gas mask was evidently demonstrated.

  • We could analyse the fire behavior using the developed software for fire safety assessment in a large space such as atrium. But Korean building law hasn't admitted the result of fire risk assessment in atrium. In the legislation fire resistant wall or shutter must be required between atrium and office rooms, That has obstructed development of building design and fire protection technique in Korea. From this point of view, we made scenarios of fire spread between atrium and office rooms, and then computed fire spread and fire phenomena using FASTLite and Breakl. In this study, we can decide that fire compartmentalization between atrium and office rooms doesn't require in Atrium building if the material and fire protection system were reliable. Consequently, Korean Fire Protection Regulations have to consider in direction of increasing freedom of building.

  • In this paper, the fire safety management plan and the emergency action program for the railway safety improvement were reviewed. In the fire safety management plan, a series of preventive methods answering to such as a smoke exhaust installation, a fire warning device and a guide inducement will be come into preparation. Also, the damage reducing methods such as complement of fire safety equipments, establishment of refuge & escape system, consolidation of real-time control on fire response and operation procedure will be required for early repressing fire and minimizing fatality.

  • 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.

  • The purpose of this study is to analyze four cases of firefighter burns in various fire scenes and to find prevention measures to decrease firefighter injuries. Among the analysis reports prepared by the National Fire Research Institute of Korea from 2016 to 2020, four burn-related accidents are summarized and the main causes are conveyed. The four accidents include second-degree burns from using extinguishers during containment of fires; nine firefighters burned due to re-ignition in the LPG car repair shop; two firefighters injured with third-degree burns from using fire extinguishers during life-saving events in residential housing; and injuries from the radiant heat of the tank BLEVE near the factory fire. These cases are comprehensively investigated in their respective scenes and analyzed based on the fire site investigation reports from the fire department and related theoretical explanations of risk for each accident scene. In the third case study, some experimental research is conducted to evaluate the risk involved with the use of safety gloves. This is evaluated by reviewing Fire Tactics and Standard Operational Procedures (SOP) to determine improvements and recommendations for an efficient firefighting response. Results show that the main causes of burn accidents are the insufficient use of personal protective equipment (PPE), such as safety gloves, and the failure to follow firefighting tactics or SOPs. Through the accident investigation and assessment, it is concluded that to reduce the frequency of burn accidents, the performance of firefighting equipment, SOPs, protection tactics, and safety policy systems require improvement.

  • To enhance safety in dangerous situations, it is essential to provide practice-oriented safety education. However, direct experiences can be limited, and thus, metaverse-based safety education is emerging as an alternative. In this study, we analyzed the first official metaverse safety education program of the Korea Ministry of Education, mainly focusing on its title, objectives, content, and results using the Revised PRISMA framework. The program concentrates on "life safety" for "fire safety," "disaster safety" for "earthquake safety," and "first aid" for "abrasions, burns, fractures, cardiopulmonary resuscitation, and the use of AED." We classified the objectives of the entire program and its three sub-programs, and identified the knowledge, main practice tasks, and their results. The aim of this study is to promote an understanding of the main cases of national-led metaverse safety education and infer the practical safety education contents emphasized to Korean school-age students.

  • Fire model shall be verified and validated to reliably show the predictive capabilities for a specific use. In the process of model verification and validation, both the acceptable uses and limitation of fire model are established. In this study, the results of FDS simulation are compared with the data of PRISME experiment such as temperature, heat release rate, heat flux, product concentrations in the under-ventilated two-room condition. Furthermore, the sensitivity of FDS under ventilation condition changes are evaluated. FDS provide the reliable prediction for under-ventilated two-room fire scenario with slightly deviation.

  • Weight-bearing building materials are substantially weakened under high temperatures, and this is evident through the collapse of structures once engulfed by fire. Currently, there is no scientific or technological process of evaluating the real-time structural stability of a building whcih is engulfed by flame. There are many building design specifications which aim to reduce the risk of fire, but little consideration given to fire officer safety while operating in a dangerous building. This paper aims to provide direction within building policy in order to ensure the safe evacuation of fire-fighters in case of an impending building collapse. This paper suggests evaluation criteria for buildings which are damaged due to fire, autilizing current information on fire-resistant building design and a fire-resistant capacity.

  • Fire disasters have frequently happened in concrete structures, which resulted in severe structural damages and unsafety. In this case, the method which had evaluated the safety of damaged structures was often unaccepted from most of stakeholders and engineers. The objective of this study is to develope the procedure and method to be able to determine the safety. Numerical simulation was applied to produce the maximum temperature and temperature distribution. Nextly, temperature propagation analysis was performed to plot temperature gradients at each depth and location. The material strength curve versus temperature was applied to determine the safety of concrete structures damaged by fire. The maximum temperature should be calibrated considering real fire records ; magnitude, intensity, situation etc. The results shows that the selected procedure and method was applicable and practical.
