The first operation of alarm system starts at a detector. And the largest effect is produced on the operation of detector by the fire source position and installation position. Nevertheless, the Korean standard for the installation of detector only specifies matters of fire detector installation according to area and height, without consideration of installation position and fire source position. Therefore, this study carried out a fire test in consideration of detector installation position and fire source position (5 places) in order to minimize casualties owing to the fast operation of fire detector when a fire occurred. Considering that it took the longest time for a detector close to a wall to work in the results of this test, it was possible to find that a minimum clearance to the wall was required.

지하공간은 지상과는 달리 공간의 특성상 밀폐된 구조가 많아 화재 발생시 피난형태나 화염 및 연기의 움직임이 다른 것이 특징이다. 때문에 지상공간에 비하여 방재설비나 적용기준이 많이 강화되어 있다. 본고에서는 지하공간 화재의 특성 및 방재설비에 관하여 보다 자세히 알아본다.

고층건물의 피난경로 제연설비는 차압형성과 방연풍량공급의 두 가지 목적을 가진다. 그러나 고층건물의 구조와 연돌효과 때문에 가압에 어느 정도의 기술적 고려가 필요하다. 피난계단실과 승강기승강로를 직접 가압하고 과압배출설비를 설치함으로써 합리적인 가압효과를 얻을 수 있다.

This study is related with fire risk assessment for occupant of the area adjacent to not enclosed atrium through the computer modeling and application of enhanced fire protection systems depending on the result. Fire scenario is intended to evaluate the impact of a fire from atrium base within the corridor adjacent to the atrium and to compare with egress time depending on the warning system. The major purpose of this study is to figure out fire life safety for occupant adjacent to atrium through the computer simulation and to suggest alternative option in case the occupant safety is not guaranteed.

A total of 19 elevators for evacuation were installed in the Lotte World Tower and it is planned to operate the shuttle using the manual key from five refuge floors to the 1st floor in an emergency. In the event of a fire or other disaster, it is necessary to conduct intensive analysis to determine how much RSET reduction could be achieved using the evacuation elevator compared to the existing evacuation plans. When the optimal transportation sharing ratio by the evacuation elevators was 40% at the Lotte World Tower, the RSET of the evacuation scenario in parallel with the elevators in the entire building was calculated to be 1 hour and 2 minutes. The RSET of a conventional evacuation scenario (Walking along the stairs without using the elevators) was calculated to be 1 hour 29 minutes, therefore, the former evacuation scenario were found to have a shortening effect of approximately 27 minutes compared to the latter. On the other hand, to maintain this effect, each part of the evacuation route using the elevator must have the capability to protect the evacuee from any hazards caused by fires, such as smoke, flame, and radiant heat during the evacuation. Moreover, the evacuation route should be continuous from the residence position of the elevator user to the final evacuation site, and be recognized easily.

Since subway fire disaster at Daegu, Korea smoke control system and passengers evacuation distance has been focused to reform. Existing smoke control facilities need to expand volume of ventilation capacity however, the complicate subway station structure can hardly react dispersion of smokes from massive subway cabin fire. Smoke flow at platform level move upward thought vertical stairway and passengers evacuation goes with same direction. The victims of evacuees from subway station fire mainly due to exposure of heat radiation and smoke. The study demonstration the effect of downward evacuates stairway system by separating evacuation route to smoke movement pass way including saving times of evacuation.

현재의 안전설비기준은 정량적 관점에서 정의되었고, 선박 재난 시나리오에 관한 대응수준을 평가할 방법이 없다. 선박, 특히 여객선 승객의 안전성을 향상시키기 위해서는 설계단계 혹은 증개축단계에서 성능기반의 피난안전설계에 의한 평가를 통해 문제점을 파악하고 개선안을 제실할 필요가 있다.

2003년 대구지하철화재를 보면 각종 대형 화재사고에서 법정 피난유도(유도등, 조명등)만으로는 화재 시 발생하는 연기 및 정전에 의하여 피난방향을 유도할 수 없음이 증명되었으며, 건축 계획적 측면에서의 안전을 확보하였다 하더라도 비상시 유도 설비들이 유도성능을 제대로 발휘하지 못 할 경우에 화재 상황으로부터 피난의 위험성을 가지고 있다고 할 수 있다. 따라서 소방 설비의 의존이 필요치 않은 자체적인 발광이 가능한 축광 안전용품이 필요시 하게 되었으며, 이에 현재 사용하고 있는 기존의 축광제품은 휘도가 떨어져 사실상 그 효과가 미미하며, 이 문제점을 해결하고자 지속발광 가능한 축광소재를 개발 하고자 한다.

This paper tried to verify whether the fixed fire fighting system (FFFS) that is installed in road tunnel improves evacuation performance or not. Verification was performed according to the Disaster Prevention Facilities Installation and Management Guide at Road Tunnel. Twenty seven different fire scenarios were set up for the verification and the cases that FFFS was installed were compared with the cases that FFFS was not installed. The result of the comparison showed that the average equivalent death was reduced in 26 cases out of 27 cases when water spray extinguishing system was installed. It was confirmed that the risk when was not installed was unacceptable in Hong Kong and the Netherlands. On the other hand, it was confirmed that the risk was reduced to as low as reasonably practicable (ALARP) when was installed. The cumulative frequency of average death in case with FFFS was compared against the frequency of death without FFFS: death of one or more is about 50 times less; 10 or more is about 100 times less; and the death of more than 100 is four times less. It was verified that FFFS makes improved conditions to escape from the fires in road tunnel.
