  • As building becomes larger, taller and more complex due to industrialization and urbanization, it tends to be vulnerable to fire and establishment of effective measures for fire safety is demanded. Especially the fact that the smoke hinders evacuation and fire-fighting activities as well as becomes the major cause of life casualty emphasizes the importance of smoke control system. To design and operate the smoke control system success folly, it is necessary to analyze and predict precisely the thermoflow induced by fire in building. The unsteady three-dimensional analysis of thermoflow induced by fire with diverse variables such as building structure, fire conditions and smoke control facilities can be effectively carried out with numerical method In this study, using the FDS(Fire Dynamics Simulation) program that spreads widely as the analysis tool for thermoflow of fire, the analysis of thermoflow in partition of building induced by fire and comparison with the experimental results for assessment of numerical analysis are presented.

  • Fire station is a response agency of disaster management. Its various field experience and materials could build up to database to support fire prevention and fire fighting, but it has not been worked out efficiently. To overcome this inefficiency, National Emergency Management Agency(NEMA) has made total improvement in "National Fire Investigation Data Classification System" mainly done by its Fire Investigation and Analysis Team. This study reviews existing fire investigation and data accumulation and analysis process so that it could be used as a basic data for "National Fire Investigation Data Classification System" operation.

  • 화학공장과 제조업 등의 사업장에서 발생하는 화재 및 폭발은 설비와 건물의 파괴뿐만 아니라 사업장의 근로자와 인근 주민에 대한 인명 피해까지 초래하는 경우가 많으므로 공정 안전을 위해 화재 및 폭발 분야의 연구에 많은 관심을 가져야 한다. 방화(Fire Protection) 및 방폭(Fire Protection)에 관련되는 특성치로 MSDS의 5번째 항목인 폭발화재시대처방법(Fire-fighting Measures)에서는 폭발(연소)한계(Explosive Limit 혹은 Flammability Limit), 인화점(Flash Point), 최소발화온도(AIT: Auto-ignition Temperature)가 제시되고 있다.(중략)

  • This report is announced about thermal lag of painted heat detectors. Thermal lag is forecast result from painting the part of heat receiving. It is delayed responsive time to assume fire fighting, escape. Test is simulated that heat detector is painted by synthetic resin emulsion paint according to the circumstance of installation. Painting method, number, thick etc is determined by research worker based on the popular idea.

  • Recent social needs for promoting traffic safety increased and the demand social security in economic, increasing the demand for environmentally friendly rail transport. In particular, when train express such as to secure reliability KTX(Korea Train eXpress) from potential disaster(fire) in the train operation caused by the train express running has been very important. Railroad fire extinguishing system is operated to fire exploding before reaching the flashing point more important than early to quickly detect because of CAN(Controller Area Network) communication to fire suppression and fire receiver, interface, fire fighting equipment from HMI((Human Machine Interface) and fire high-performance to research and development for intelligent composite fire receiver is required.

  • The placement of Korean fire-fighting administrative power in urban areas shows regional unbalance. In an ideal system, all citizens would be provided with equal fire protection and rescue services, but this is usually difficult to realize due to regional conditions or budget problems. In the case of Busan Metropolitan City, we deduced that it is impossible for half of the buildings to receive rescue services within 5 min, and the conditions are much worse for areas with long or wide fire-fighting service regions. The approach vulnerability for the existing emergency rescue squad locations was assessed. The results revealed that if a rescue team's location is shifted, the improvement effect will be virtually insignificant because of their geographical position. Therefore, this study suggests the establishment of additional rescue squads. It is proven that adding 5 rescue centers in the following locations could solve the problem of approach vulnerability: Bukbu, Gangseo, Geumjeong, Gijang, and Haeundae, in order of effectiveness. The number of buildings in the areas is 53,546.
