  • 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.

  • 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 apartment buildings, casualties, especially fatalities have occurred in balcony areas in fires if residents fail to escape to the main entrance. Potential consequences of a particular infrequent event should be considered. In attempting to design apartment buildings for fire safety, alternative escape methods such as vertical penetration could be considered. The purpose of this study is to investigate present building regulations regarding apartment buildings and examine pros and cons of the current escape method and alternative escape methods. Focus group interview was conducted to discuss problems of fire escape methods. In addition, questionnaires were distributed to field professionals working in architecture, construction and related industries. Among 500 questionnaires distributed, 192 questionnaires were collected. Usable 162 questionnaires were analyzed using SPSS 15. Regarding alternative fire escape methods, several concerns were mentioned. Safety, privacy, security, effectiveness of escape, water proof problems were raised. Based on the opinions, vertical penetration between apartment unit appeared more safe, secure, effective than horizontal penetration. However, both methods have its own pros and cons under specific contexts. Alternative escape methods need be considered for a selective options for residents in case of fire.

  • This study wants to provide basic data on effective escape safety plans when residents of apartment complex use residential convenience facilities. The findings of the analysis are as follows. First, when this study applied the actual number of users (No=54) of those facilities, the existence of elevator for escape reduced the escape time by 189.0 seconds. Second, when the number of users was calculated on the standard of the number of people who can be accommodated for performance based design (No=316), the existence of the elevator for escape reduced the escape time by 173.5 seconds. Finally, when the number of users was calculated on the standard of installing fire-fighting facilities (No=122), the existence of the elevator for escape reduced the escape time by 159.2 seconds. As a result, it was found that elevator for escape reduces the escape time from fire. Accordingly, it is necessary to revise the construction law to make it obligatory for residential convenience facilities to be equipped with elevator for escape. Currently, apartment buildings lower than 30 stories have either elevator for passengers or elevator for escape. Thus, in future studies, it is necessary to compare escape times in fire depending on the kinds of elevator, and identify the usefulness of elevator for escape.

  • As high-rise Apartment buildings increase the importance of fire prevention and escape performance. While these buildings provide dwellers with much more houses, they have the basic escape safety problem in their apartment buildings. In these respect, this study aims to present the Principles of Fire protection for the escape performance of apartment buildings. This study reviews basic theories of escape in apartment buildings. I figure out the characteristics of the fires in apartment buildings by case studying the fire in the apartment buildings, and find out the existing problems for escape performance and fire prevention by surveying. In this study, the major findings are as follows: The planning method should be based on the escape performance. In the planning stage, fire safety should be considered more seriously than law and economic factors.

  • With the increase of apartments and expansion of balcony areas, fire safety issues are becoming more important. Many researchers have conducted a lot of researches to reduce vertical flame spread in the balcony when an apartment unit is in fire. However, there have rarely been studies to use balcony area as a space for fire escape and evacuation. The study aims to examine the conditions of balcony use in apartments in order to find out prevention elements from fire escape and evacuation, and to investigate residents' satisfaction with balcony. For this study, questionnaires were collected from apartment residents and workers of architectural planning and construction companies. The findings show as follows: first, the balcony is generally used as a storage in each apartment unit nowadays. Second, when fire breaks out, many storage items could disturb residents' safe escape by blocking escape route, and easily promote to spread flame vertically in the balcony.

  • In the disaster prevention design, it is important point to secure escape way at event of fire which makes people away from the fire more quickly and safely. Development of construction techniques leads to build many skyscrapers, and skyscrapers contains various dangers and increase levels of disaster. At basic design stage for skyscrapers, evacuation scenario is considered that occupants are escape using escape stairs and emergency elevators simultaneously at fire, but there is no evacuation program to simulate using escape stairs and emergency elevators at the same time. In this study, evacuation simulation is performed using method of VR which is based on Virtools of 3DVIA Co., and Simulex of IES Co. for safety and effectiveness where occupants are escape using escape stairs and emergency elevators simultaneously at the fire.

  • The purpose of this paper is to improve the evacuation stability of residents in apartment fire. For this purpose, the actual condition survey about the obstacles was conducted on 3,056 escape stairs in the 183 apartments. In addition, the questionnaire investigation was carried out a survey targeting the residents of apartments about their experience of fire safety education, perception on safety management of escape stairs, and perception on fire safety. As a result of investigation, we confirmed that the obstacles were formed in the 1,916 escape stairs among the 3,056 escape stairs of the 183 apartments (percent of barricades in escape stairs: 62.70%). Furthermore, it showed that fire safety education experience was found to be 83.10% of subject. The perception on safety management of the subjects in the escape step and the perception on fire safety were $3.84{\pm}0.75%$, and $3.49{\pm}0.61$, respectively. In the results, most of the subjects had a fire safety education and knew how to safety management the escape stairs but, the practice of the safety management action was low. Based on the results in the paper, the policy proposal is that the fire safety education is emphasized to change from the perception to action.
