The aim of this study is to investigate the direction of improvement of safety experience education through the analysis of the evacuation time experiment. For the study, test subjects were divided into groups of similar body size and weight. The test subjects were directly experienced four evacuation devices, and the experience time was measured. As a result of the analysis of the total time from the installation of the evacuation device to the escape, the time was measured in the order of Descending Life Line-Tilt-Down Rescue Line-Vertical Escape Chute-air safety mat. In the case of evaluating the evacuation time using evacuation mechanisms, the evacuation time was measured in the order of air safety mat-Tilt-Tilt-Down Rescue Line-Descending Life Line-Vertical Escape Chute. In the first and second experiments of the Descending Life Line, time differences were observed. The escape time using the Descending Life Line was reduced in the second experiment than in the first experiment. As shown in this result, education through experience has shown that behavioral confidence and time can be managed. The conclusion of this study is that the goal of safety education is to minimize human life and property damage. Therefore, in order to bring this effect to more people, it is necessary to make efforts to keep self-safe through experiential education.

The aim of the study intends to investigate the recognition of fire safety of traditional market employee in Masan city and to provide the base data for the fire safety. The results of the study are as follows. The traditional market employee have high interest in fire safety and recognize that the possibility of fire is high in market. The traditional market employee of 46.0% takes fire safety education and preferred self-government merchant association in market as education place. This study shows that the traditional market employee of 41.5% recognize a fire escape route. In order to prevent the fire of traditional market, the strong activity of market fire staff and the periodic fire inspection of fire department are recommended.

Recently the consideration for occupant's security has been raised as very important design element from the fire by building's large sized, higher storied, and its compounded. But the domestic laws regulated the predicative laws according to the technical standard which has no difference from the past domestic evacuation regulation. Therefore, regulation of escape code and developing technology for Korean conditions are needed to reduce victims during disaster by protecting occupant and guiding people to safe places.

Recently, the expansion of underground shopping street has a tendency to make a large maze in urban underground space. As the passers -by in underground streets have little information about these spaces, there can be a great danger at fire. From this point of view, this study aims at offering the basic data which needs to make a reasonable planning of escape facilities of underground shopping street. Therefore, safe performance evaluation program is developed for evaluating inhabitants' safety at each model. This program is composed of systematic equations which generalize each phenomenon at fire.

Recently, property and life loss is increasing internally and externally, due to fire spread in high-rise buildings which results from a variety of disasters like fire and terror. In this study, therefore, an evacuation simulation was performed to predict escape behaviors of occupants and assess escape safety in high-rise office buildings after setting up each scenario, as part of safety measures for high-rise buildings. Based on the results and data obtained, escape safety was assessed, finally. The results and suggestions of this study are as follows. Firstly, most of the present researches on high-rise building and multiple-use facilities are weighted towards qualitative perspectives. It is, therefore, considered that we have to establish concrete, practical, systematical and rational safety measures to minimize damages in dangerous situations, by analyzing security plans for high-rise buildings in depth and preparing for those situations from various angles. Secondly, setting up evacuation sections in security plans for high-rise buildings is an important factor which influences refuge. Thirdly, in relation to security plans for high-rise buildings, it is possible to reduce the entire time for escape, by setting up escape exits of each floor in consideration of a simultaneous evacuation situation.

The number of medical welfare facilities caring for the elderly with paralysis and dementia has been increasing rapidly because of the change in the way of supporting the elderly, stemming from an increase in the number of the elderly and working couples. These medical welfare facilities are usually installed all over the city and are gradually becoming high-rise. Few inmates are capable of making their own decisions in case of fire at night and when there are no escape routes such as ramps for evacuation, leading to massive casualties. This study aimed to identify problems in evacuation in the medical welfare facilities for the elderly in Goyang city. This city has the largest number of medical welfare facilities for the elderly per unit area. The following strategies could aid in better evacuation: secure ramps or bed escape elevators; the bedrooms of the inmates should have one-hour fire resistance; the stairs should have the structure of an enclosed stairway; the necessary apparatus for evacuation, such as an escape chute, should be installed; and, to conclude, a business agreement with neighboring agencies to help inmates escape during the fire. The state should implement necessary measures to protect the lives and property of the people. Rapid implementation of this proposal is necessary for the evacuation safety of an increasing number of medical welfare facilities for the elderly.

In accordance with the revision of "Special act on the safety control of publicly used establishments", this study is aim to measure the change in evacuation time due to whether safety facilities, etc. are installed of a room escape cafe business and kids cafe business(hereinafter referred to as "New publicly used establishments"), which were added as new targets of the publicly used business from June 8, 2022. In the case of new publicly used establishments or publicly used establishments whose owners are changed after the revision of the relevant laws, safety facilities, etc. are installed and maintained under the "Special act on the safety control of publicly used establishments", but in the case of existing businesses that have been operating even before the revision of the law, the business continues without safety facilities, etc. installed because the revised law is not retroactively applied. The purpose of this study is to compare and analyze the change in evacuation time by measuring the evacuation time to operating before the revision of the law to simulate evacuation at existing new publicly used establishments without safety facilities, etc. and measure the evacuation time at new publicly used establishments with safety facilities after the revision of the law

The objectives of this study is analysis of the characteristics of fire risk and survey of narrow dwelling space(the Karaoke, Gosiwon etc). The narrow dwelling space has special structure characteristics; the narrow and the complex escape rote. Gosiwon have very separate and exclusive space room, so have the problem a suppression of fire. Furthermore almost Karaokes located in basement have a complex and limitary escape rote. Therefore we should research and development the exploration equipment that search a source of the fire and a emergency rescuer in the scene of the fire.

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.
