현재 국내건축물은 주택, 빌라 등을 제외한 대부분의 건물에 소방시설을 적용하고 있다. 그렇지만 소방시설의 활용은 이천물류 창고 화재, 부산 노래방화재, 대구 지하철 참사와 최근 부산의 고층 오피스텔 화재 등을 볼 때 제대로 작동하지 않고 있다. 이처럼 우리나라의 실제 화재시 소방설비가 제대로 작동이 되지 않아 인명피해, 재산피해 등이 계속해서 발생되고 있다. 이에 본 연구에서는 소방시설 중 가장 널리 사용되고 초기소화에 가장 중요하게 사용되는 경보설비 및 피난설비의 관리 실태를 파악하고 그것에 대한 문제점을 데이터화하여 실제 화재시 소방시설의 적극적인 활용을 위한 해결점을 찾고자 한다.

Purpose: In this study, in order to ensure the evacuation safety of plant facilities, we analyze the relationship between the height of smoke removal boundary walls, the presence or absence of smoke removal equipment, and evacuation safety. Method: Using fire and evacuation simulations, evacuation safety was analyzed through changes in the height of the smoke removal boundary wall, air supply volume and exhaust volume according to vertical dista. Result: In the case of visible drawings, if only 0.6m of boundary wall is used, the time below 5m reaches the shortest, and 1.2m of boundary width is 20% longer than when using smoke removal facilities. In the case of temperature, 1.2m is 20% longer than 0.6m when only the boundary width is used without smoke removal facilities. Conclusion: It was found that increasing the length of the smoke removal boundary wall could affect visibility, and installing a smoke removal facility would affect temperature. Therefore, it is determined that an appropriate smoke removal plan and smoke removal equipment should be installed in consideration of the process characteristics.

As more and more the number of a couple working together for living has increased and an interest in early education has risen, daycare centers have made an effort to provide effective and good service beyond 'nursery care'. The most important thing in building in the event of disasters is safe evacuation of occupants. Having 'safe evacuation route' is required to reduce damage caused by disasters, It is necessary to give continuous and repeated training for right evacuation to infant and children so that they can evacuation successfully. This study examined problems that need improvement so that evacuation instrument installed in daycare centers can be used better by analyzing a survey of evacuation related facilities on daycare centers. This study found that laws and regulations on safety should be improved, evacuation facilities prepared against should be maintained regularly by relevant authorities, training for coping with disasters should be provied and evacuation instruments which are suitable for children.

This paper proposes and implements a LoRa-based emergency exit guide system which can direct the optimal refuge path accounting for the real state of the fires. Each 4-way emergency exit guide sign presents a right direction through one of four LED signs toward the possible exit dynamically calculated by the shortest path algorithm. We constructed a simulation environment with 8 spots of the emergency exit guide signs and 2 exits, which can simulate variant cases of fire accidents, and showed that the proposed algorithm can presents the right guidance for each emergency exit guide sign. We also evaluated the performances of LoRa-based wireless communications using a self developed communication module in the various indoor and outdoor environments. The proposed system can be applied to small and medium sized buildings as well as larger ones in terms of cost efficiency, in which there's no needs to invest for the complex equipments except only sensors and emergency exit guide signs.

The Performance-based fire protection design required to construct super high-rise building is the active measure for the evaluation of fire risks and the establishment of fire protection systems on the basis of engineering analysis, which is more efficient and proper than existing prescriptive-based design. This study applied time-line analysis of RSET is required safe egress time and ASET is available safe egress time with the fire and evacuation simulation to analyze. The result of this study showed the sprinkler system increased ASET and fire detection and alarm system reduced RSET efficiently. Reduced evacuation time influences to secure the life safety. Also it is essential to maintain the fire suppression system and fire detection & alarm system properly. Database of fire movement and evacuation action program are useful for the performance-based design.

The Korea Foldable safe pathway system is an evacuation support system to get temporary evacuation route in railway tunnel and large space fires. A prevention smoke screen is unfolded in fires and it is needed to prevent heat and smoke from fire source. Therefore, ventilation system for positive pressure condition is equipped with foldable safe pathway system. Numerical analyses of temperature and pressure distribution with distance from fire source were performed considering fire scenario of new train vehicle. The smoke temperatures did not exceed $200^{\circ}C$ that distance from the fire source was more than 20 m and smoke pressure was reduced with distance from fire source. Maximum smoke pressure was 14 Pa and average pressure was 6 Pa in position of prevention smoke screen. As results, to install foldable safe pathway system, ventilation system is need to maintain 6 Pa positive pressure condition.

Emergency lantern is an escape equipment of fire fighting. This equipment of obligation installation in buildings. But, We cast doubt on this equipment's reliability. Therefor we have need to study of this equipment's reliability. This paper research general emergency lantern for up grade reliability. For connection to fire alarm system, alarm for get lost general emergency lantern, and pilot lamp for interruption of electric power, and charge to rechargeable battery in general emergency lantern from fire alarm system. Then view very good result in reliability.

The escape connecting gallery in a tunnel on a road is one of emergency equipment to ensure safety for passer in the tunnel against the tunnel fire. Government stipulate over 500m tunnel has the cross passage at intervals of less then 250 m. However, this lump estimated interval is generated the concerns of exaggeration and under construction because peculiarity of the tunnel ex. The velocity of the tunnel airflow, an incline, degree of a fire, and innering area are not considered. The study indicate the way to estimate of the cross passage considered an incline and the velocity of the tunnel airflow for efficient application of cross passage on the tunnel design. As a result, in 0.0 m/s and 1.0 m/s of the velocity of the tunnel airflow case, the movement of smoke is influenced by the incline however, in 20 m/s case, it isn't influenced by incline much. According to the velocity of tunnel airflow and the incline, optimum interval of cross passage is not corresponded. Therefore established lump estimate that has 250 m intervals would be changed to estimate of optimum interval of cross passage that considered about the properties of tunnel, the velocity of the tunnel airflow, incline, degree of a fire and innering area of the tunnel.

화재발생시 기존의 비상경보설비는 화재경보라는 단순한 정보만을 제공함으로서 대피자의 입장에서는 건축물의 안전상황 및 피난상황을 식별할 수 없다. 따라서 화재발생시 대피자들이 밀집되는 병목현상이나 화재 영향에 노출되어 있는 피난경로로의 대피 등은 화재 피해를 가중시키고 있다. 본 연구의 목적은 현재 응용 가능한 대표적인 Ubiquitous 기술 중 개인의 위치를 식별하여 이용하는 위치인식기술 RSSI(Received Signal Strength Indication)을 활용한다. RSSI를 기반으로 한 LQI(Link Quality Indication)는 무선통신기간의 거리인식을 통해 대피자 정보 시스템 정보를 획득한다. 이러한 위치정보시스템을 응용하여 개발한 화재 안전 시스템은 화재 위치를 식별하고 화재위험 지역의 상황변화를 예측하여 피난경로 선정을 위한 안전정보를 제공하여 준다.
