This study presented the development of a user centered school facility fire safety evaluation model that would support fire safety evaluation, which is globally recognized as being important in terms of school safety, to be more efficiently implemented in the school field mainly by students. The study consisted of five steps. First, actual condition survey tools were developed based on the major fire safety evaluation items derived through literature review. Second, the characteristics of domestic school facilities in terms of fire safety were developed using the survey tools. Third, an evaluation model at a level utilizable by students was developed based on the foregoing characteristics. Fourth, the applicability of the model was verified through a trial application of the model to elementary school students. Finally, legal and institutional improvement plans and fire safety education materials were presented through a policy proposal.

From the viewpoint of fire-fighting activities, public building have structural and management problems in fire, so evacuation disturbance and risk of expanding combustion are high. As a result of analyzing various fire fragile factors of public building, The evaluation areas were derived from safety systems, fire-fighting facility, structure safety, general safety and the evaluation factors were presented. Also, the characteristics of domestic and foreign certification systems were analyzed by comparing and analyzing the status of fire safety performance certification system for 6 domestic and overseas apartment houses. In conclusion, the 5 convergence directions of certification system and 22 evaluation items by 4 evaluation fields were derived, and based on this, we have established 3 convergence introduction plans of fire safety performance certification system of public building.

Human and material damage can be reduced if the risk is evaluated by engineering analysis of fire combustion products, smoke concentration, and smoke movement speed in the event of a fire in apartment houses and officetels. In this study, a lot of research on related safety evaluation in the basement needs to be studied and reflected in design, so experimental research was conducted to analyze the flow of smoke through computer simulation and provide analysis data through evacuation safety evaluation. First of all, the five-story underground parking lot subject to simulation has a large floor area, which is advantageous for improving evacuation safety performance, but it uses temperature detectors to increase detection time and fire spread speed. Second, it was analyzed that the evacuation time at all evacuation ports did not exceed the evacuation time, and as the time from the start of evacuation to the evacuation time was 216.9% compared to the travel time, it was evaluated that the safety performance of the evacuation was secured. Third, the above simulation results are a comprehensive safety evaluation based on the non-operation of fire extinguishing facilities in the fire room to increase safety, which means that smoother evacuation safety performance can be secured by linking fire extinguishing facilities.

Although the urban rail vehicle is exposed to the fire disaster, most country, except only a few advanced country, is insufficient to take a measure against the fire accident. Safety regulation modification, fire safety standard of the materials. and each material's fire resistance of the rail vehicle have been upgraded until the Daegu fire disaster in Korea. For that reason, In this study, current techniques of fire safety evaluation are analyzed and fire safety degrees of rail vehicles are compared with the change of interiors which is met to the fire safety standard of urban rail vehicle.

Under the Korean Enforcement Decree of the Building Act, all high story apartment houses more than 5 stories high are mandated to install a fire evacuation system to ensure safe evacuation from fire accidents and providing quick and easy bidirectional escape route when main entrance is blocked by flame or toxic smoke. However, the current fire evacuation system shows a lack of understanding from residents and thus is widely ignored for having insufficient safety functions, especially vis-à-vis fire emergencies. Studies have found that an alternative evacuation method, the escapable fire evacuation system, has been analyzed for safety evaluation compared with the conventional passive fire escape system and can bring efficient and safer solutions, providing high rise residents escape from fire accidents. Evaluation for safety evacuation has been performed by the Fire Dynamics Simulation and applying Pathfinder simulation. This resulted in providing appropriate escape routes within the safety escape time and allowed for people in high rise building fires to get to safety.

This study aims to overcome the problems of existing fire fighting drills and build a practical and effective fire fighting drill system to enhance emergency response capabilities. The unexpected scenarios fire fighting drill is to conduct drills with no scenarios and draw conclusions with quantified outcomes in real time, which provides the object evaluation system. The unexpected scenarios fire fighting drill is based on the IoT sensor-based drill evaluation system to suit individual requirement of drilling spots. This study also includes drill field test conducted to examine the applicability of the evaluation system for quantified outcomes. It is considered that the evaluation system of this paper will contribute to systematization and quantification of fire fighting drill, raise trainees' safety consciousness, and ultimately increase the actual fire fighting response capabilities.

The fire event occurred in fire proof zone often causes serious electrical problems such as shorts, ground faults, or open circuits in nuclear power plants. These would be directed to the loss of safe shutdown capabilities performed by safety related systems and equipments. The fire event can treat the basic design principle that safety systems should keep their functions with redundancy and independency. In case of a multi-core cable fire, operators can not perform their mission properly and can misjudge the situation because of spurious operation, wrong indication or instrument. These would deteriorate the plant capabilities of safety shutdown and make disastrous conditions. In this paper, the characteristic of cable fire is investigated and the heat-flux evaluation for cable fire is studied. Moreover, a diagnostic methodology for degraded cable in nuclear power plants is presented.

A large number of Computer-based fire growth and Evacuation model have been developed for various purpose and many of these are widely used for research and engineering. And Most of Egress simulation program are ordinary case only related to human behavior But Egress safety Evaluation is very closed to smog movement. It is well known that the Egress simulation program made by Tokyo Fire Department are related to smog movement. So It is the aim of this study to investigate on the Development of Egress Simulation for Evacuation Safety Evaluation of Tokyo Fire Dept. Department in Japan.

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.

Recently, advanced countries assessment the risk of fire to prevent large-scale damage to high-rise buildings, In addition, performance-Based design, which is a fire risk assessment, is being conducted in Korea to prevent massive damage to high-rise buildings. However, unlike advanced countries, fire risk assessment in Korea is subject to fire risk assessment only for objects subject to consent from fire-fighting facilities such as building permits, When building engineers and fire-fighting engineers assessment the risk of fire, It has always been discussed because the results vary depending on which part of the evaluation is focused between economic feasibility and safety. Therefore, in this study, we would like to propose a fire risk assessment process suitable for domestic conditions by comparing the process of performance-based design, which is a domestic fire risk assessment, and the process of Iso/TC 16732 which is an overseas fire risk assessment.
