Currently many geriatric hospitals have been built in Korea because younger people don't want to care their parents and have been decreasing for labor. However, the increasing geriatric hospitals make the increasing fire safety accidents. Therefore, this study is conducted by survey and face-to-face talk for analyzing fire safety problem of twelve among 15 geriatric hospitals in the north of Chung-Buk area. The result of this study is that infection and fall accident are higher than others and fire safety implement rate of safety rule followed by CEO is 71%. Monthly safety training rate is 49% and initial fire safety training not conducted is 33%. Yearly outside fire safety training rate is 97% but workers who know how to use fire evacuation facility are 61%. Furthermore, safety instruction rate of fire safety manager is much higher than supervisor's safety instruction. The cause of accident is facility (33%). In conclusion, the institution and rule improvement need for decreasing infection and falling, increasing implement level of fire safety rule and fire safety training, participation rate of supervisor for fire safety, quality of fire safety training, and investment of fire safety facility.

On the construction site, there exists frequently a high likelihood that a fire accident can lead to a large-scale disaster. In the previous studies, the diverse outcomes have been focused on the improvement of relative statutes and tried to realize the suppression and confrontation of the fire accidents. In this study, the limitations on the site were identified through prior research reviews, and the fire risk assessment checklist was proposed through the analysis of the massive accident cases. The checklist was divided into the prevention and minimization steps and developed into 16 categories of total risk factors. According to the results from the cases applied in this study, if the installation status is checked, such as removing combustibles, and broadcasting facilities for evacuation are installed, it is expected that the casualties will be minimized or zeroed. By developing a fire risk assessment checklist, this study provides the implications of the theoretical and realistic fire accident prevention, and supports the ways to minimize the damage resulted from the fire accidents on construction sites. In the further, deriving universe and common items about repeated occurrences of a work type will be needed as a subsequent research.

In this paper, the elemental components and improving purpose in advanced safety management system are reviewed to cope with a railway fire accident. And a considering procedure(V-cycle) of long-term plan for railway fire safety improvement is proposed. For the purpose of preventing recurrence of accident, items which have to be considered in the course of accident investigation and cause analysis are presented according to the stage of investigation activity.

In this paper, various hazard factors are reviewed on the train fire accident in railway tunnel and subway. In case studies of systematic risk evaluation on the tunnel fire accident, we have learned the critical fire safety points for accident prevention and damage reduction such as fire-endurance of infrastructure, mortality of heat & toxic smoke, emergency situation control and management of escape requirements etc.. These hazard analysis study will contribute for improving the railway fire-safety and establishing the long-tenn safety management plan.

It is expected that passenger ship will be large-scale and luxurious according to the needs of modern function. A passenger short of information on the ship, so that they may be injured at the occurrence of fire accident. This study has investigated a case related to fire accident and presented basic data ship to minimize damages and loss at the occurrence of fire accident.

Since a few years ago, great disasters have often took place in domestic and abroad, such as Sampoong Department store collapse, Sea-land disaster accident, Incheon Hof fire accidents. Whenever a lot of accidents occurred such as fire, gas explosion, traffic accident, mountain accident, various disease, people required 119 first aid service. As the result, even for the last year, average 2,608 person per day were temporary treated and carried to near hospital by 119 system. But first-aid team or first grade EMT(emergency medical technician) that should provide high quality service and save important lives, might have negatively treated or made their duty only for simple transfer, when they were imminent of emergency case in every kinds of accident spot. Because they worried about medical dispute for "task restriction for EMT" decided by medical laws or rules of first aid. So it was proposed that "task restriction for EMT" should be mitigated or released in the possible range on this occasion.

According to NSSC Notice No. 2021-10, safety analysis needs to be introduced in the decommissioning plan. Public and occupational dose analyses should be conducted, specifically for unexpected radiological accidents. Herein, based on the risk matrix and analytic hierarchy process, the method of selecting accident scenarios during the decommissioning of nuclear power plants has been proposed. During decommissioning, the generated spent resin exhibits relatively higher activity than other generated wastes. When accidents occur, the release fraction varies depending on the conditioning method of radioactive waste and type of radioactive nuclides or accidents. Occupational dose analyses for 2 (fire and drop) among 11 accident scenarios have been performed. The radiation doses of the additional exposures caused by the fire and drop accidents are 1.67 and 4.77 mSv, respectively.

Though the probability of tunnel fire accident is very low, but critical fatalities are expected when it occurred. In this study the effect of critical safety parameters on tunnel fire accident are examined using probabilistic technique. Fire detection time, smoke spread velocity, passenger escape velocity, flash-over time, and emergency service arrival time are considered. In order to estimate the uncertainties of input parameters Monte Carlo simulation are used, and fatalities for each assumed accident scenarios are obtained as results. For the efficiency of iterative calculation PRA(Probabilistic Risk Analysis) code is developed in this study. As a result fire detection have large effect.

Many railway safety measures are carried out after Daegue subway fire accident. Such as replacement of train interior material, fire extinguish and toxic gas evacuation facilities, exercise on emergency response, setting up of national safety management system, and safety technology research. But these safety measures are not considered by system safety due to lack of risk and hazard information. In order to assess fire risk on system level, we proposed hazard events and causes classification for railway fire accident risk analysis.

The number of fire and explosion accidents caused by pyrolysis oil and gas at waste plastic pyrolysis plants is increasing, but accident status and safety conditions have not been clearly identified. Therefore, the aim of the study was to identify the risks of the waste plastic pyrolysis process and suggest appropriate safety management measures. We collected information on 19 cases of fire and explosion accidents that occurred between 2010 and 2021 at 26 waste plastic pyrolysis plants using the Korea Occupational Safety and Health Agency (KOSHA) database and media reports. The mechanical, managerial, personnel-related, and environmental problems within a plant and problems related to government agencies and the design, manufacturing, and installation companies involved with pyrolysis equipment were analyzed using the 4Ms of Machines, Management, Man, and Media, as well as the System-Theoretic Accident Model and Processes (STAMP) methodology for seven accident cases with accident investigation reports. Study findings indicate the need for establishing legal and institutional support measures for waste plastic pyrolysis plants in order to prevent fire and explosion accidents in the pyrolysis process. In addition, ensuring safety from the design and manufacturing stages of facilities is essential, as are measures that ensure systematic operations after the installation of safety devices.
