It would be very important to localize people at risk as soon as possible in order to minimize the damage. Generally the infrastructure should be deployed additionally for indoor positioning system. In this paper, we proposed an indoor localization system for people at risk using the existing fire alarm networks. The system detects the signal of smart devices of people in danger immediately and let the main alarm controller ring all alarms in vessel and display the position. Thus, the proposed system can make the burden much less to deploy additional network and infrastructure.

The performance based design in fire detection system, the effect of high airflow and dilution of smoke produced in any fire situation serve to increase the response time of point-type smoke detectors. This study investigated the smoke density of ceiling, under the air stream and in normal status when fire type is smoldering fires. The result of study, smoke generated in the fire was swept away from nearby spot type smoke detector which failed to actuate because dispersed in diluted form around the room. The concept of performance based design in fire detection system of protected area influenced by high airflow provided the need of active fire detection system such as air sampling smoke detection system.

The fire at a Busan indoor shooting range on November 14, 2009 was reconstructed by using a computational fluid dynamics model for fire simulations, in order to investigate the cause of the heavy death toll in a short period of time. Spread of the flame and smoke, and temperature distribution obtained by fire simulation were compared with the results of fire investigation based on the CCTV recordings. The flame and smoke flew out violently through the door into the cafeteria from the shooting range, and the cafeteria was filled with smoke just within 3 seconds followed by the onset of fire. This is consistent with the CCTV recordings. It was confirmed, as a result, that people in the cafeteria did not have enough evacuation time. The computed temperature at the door knob reached about $1400^{\circ}C$, near its melting point.

방염제품의 내구신뢰성은 국민의 화재 안전성 확보를 위한 필수 불가결의 요소로 이들 제품의 내구성능 예측은 방염성능의 지속적 유지를 위한 방염시설물 유지 관리 측면에서도 상당히 중요하다. 본 논문에서는 방염도료의 내구신뢰성 예측 및 확보를 위한 방염도료 가속수명법에 관한 연구로써, 방염도료의 고장 원인분석을 진행하였으며, 현장시험 및 현장 모사 실내 가속촉진시험을 진행하였다. 실내 가속촉진시험은 방염도료의 현장 주고장모드인 온 습도 사이클 시험으로 진행하였으며, 시험 척도로서 화학발광을 분석하여 적용하였으며 현장 데이터와 실내 촉진데이터와의 상관성 규명을 위하여 Mitab 등의 통계적 기법을 이용하여 고장유형 및 상관성을 규명하였다.

화재 현장에 투입된 소방대원들은 각종 위험한 환경에 장시간 노출된 상태로 활동을 하고 있으며 또한 열과 연기 등으로 인하여 시야 확보가 매우 어렵고 장시간 화재 진압 및 구조 활동으로 인하여 급격한 체력 저하로 야기되는 소방대원의 인명 피해가 발생되고 있다. 그러므로 본 논문에서는 이러한 인명 피해를 막기 위하여 투입된 소방대원의 위치 추적 및 상태 등을 확인하여 만약에 고립된 소방대원이 있을 경우 안전하게 탈출 할 수 있는 실내 측위 및 추적 기술에 대하여 연구한다.

Recently, the research to visualize and to reproduce evacuation situations such as terrorism, the disaster and fire indoor space has been come into the spotlight and designing a model for interior space and reliable analysis through safety evaluation of the life is required. Therefore, this paper aims to develop simulation model which is able to suggest evacuation route guidance and safety analysis by considering the major risk factor of fire in actual building. First of all, we designed 3D-based fire and evacuation model at a subway station building in Incheon and performed fire risk analysis through thermal parameters on the basis of interior materials supplied by Incheon Transit Corporation. In order to evaluate safety of a life, ASET (Available Safe Egress Time), which is the time for occupants to endure without damage, and RSET (Required Safe Egress Time) are calculated through evacuation simulation by Fire Dynamics Simulator. Finally, we can come to the conclusion that a more realistic safety assessment is carried out through indoor space model based on 3-dimension building information and simulation analysis applied by safety guideline for measurement of fire and evacuation risk.
