  • This research analyzes clean room major fire prevention standard of clean Room(FM, IRI, and NFPA Code), the structure of Performance-Based Fire Safety Design(PBD) applied the korean fire industry situation. Performance-Based Fire Safety can operate effectively the performance of fire protection equipment & building design, so the fitness of fire safety system can be embodied by operating this. moreover, cost to be consume fire safety of real building can reduce and Performance-Based Fire Safety is considered to important technique in fire protection field. A fire in a clean room may cause a serious loss by spreading smoke particles. We will be investigated by using a computational fluid dynamics, for loss prevention by smoke spreading from one fire area to another for clean room and compared the Performance-Based Fire Safety Design with the prescriptive code design. The methodology of fire safety performance-based fire safety design and guarantee of many kinds design skill of fire system and developing design procedure will be very serious one in order to improve efficiency of domestic system. Therefore, This research will be contributing to secure safety of clean room and to set up the performance-based fire safety design in Korea by regulation for the performance-based fire safety design effectively.

  • This study analyzed the effect of zoning on the distribution of pressure differentials caused by stack effect and air pressurization in a center core type of 80 story super-tall building. The results showed that maximum pressure difference more than 250 Pa can be generated by stack effect without zoning. Zoning of stairwell only resulted in 10 Pa reduction of maximum pressure difference, however, zoning of both stairwell and EV shaft especially at the same floor revealed 50 % reduction in stack effect. It was also analysed that the minimum required air flow rate occurred when the stairwell temperature reached 50 % of temperature difference between indoor and outdoor.

  • In our country, a number of fire outbreaking had been increased suddenly for 20 years from beginning of 1980's to 2001. That was related with the focus of economic policy, the rapid increasing of fire fighting objects, the change of life environment, and the increasement of usage of energy. Accordingly, we tried to enforce the function of feedback effect of fire prevention policies with analysing the trends of fire occurring from 1950's to 2006 and the correct statistical analysis.

  • When a fire is detected by a sensor of a fire detector, the fire is notified to the manager through the siren. However, if the manager is not indoors, prompt action may not be taken in the event of a fire. In this study, we would like to propose a platform system for fire prevention applying IoT to prevent problems that arise when building manager is absent. This paper presents the structure and operation principle of fire prevention platform system design using IoT, describes the overall system design through fire detector H/W design, micom S/W design and Android application development, and is expected to develop a system that can respond a little faster in case of fire.

  • To investigate numerically the effects of geometry and location of vertical opening on the thermal and chemical fire characteristics in full-scale under-ventilated compartment fires, the ventilation factor ($A\sqrt{h}$) to estimate a theoretical maximum inflow of ambient air and the mass loss rate in a heptane pool fire were fixed for all cases. It was shown that variations in door geometry affected significantly the change in thermal and chemical characteristics inside the compartment. Variations in window location resulted in the complex change in additional fire characteristics including the fire duration time and recirculating flow structure. These results were analyzed in details by the multi-dimensional flow and fire characteristics including the vent flow and fuel/air mixing phenomena.

  • It is essential that the operational system of volunteer fire brigade (VFB) playing a important role in the local disaster prevention should be effectively improved to live in safety by protecting life and property of inhabitants from a disaster. The results of this research showed that most of volunteering members of fire brigade was highly satisfied with their works and thus they voluntarily did volunteer activities. It was also found that the development of the professional education program and training course about disaster prevention should be required because members of the volunteer fire brigade lacked expertise about the disaster prevention. Moreover, in order to activate and expand VFB, the establishment of the fundamental ideology about the activities of VFB, the introduction of effective selection examination system for the VFB and the creation of department fully responsible for the management of the VFBs should be necessary as well.

  • 비정상(unsteady) 화재성장이 발생되는 반밀폐된 구획에서 환기부족화재의 열 및 화학적 특성에 관한 FDS(Fire Dynamics Simulator)의 예측성능 평가가 수행되었다. 이를 위해 실규모 ISO 9705 표준 화재실의 출입구 폭이 0.1m로 축소되었으며, spray 노즐을 통해 Heptane 연료유량은 선형적으로 증가되었다. 수치계산에 대한 신뢰도 확보를 위하여 동일조건에서 수행된 실험결과와의 상세한 비교가 이루어졌다. 적절한 격자계를 이용한 FDS의 결과는 구획 내부의 온도 및 열유속(heat flux)은 비교적 잘 예측하지만, 비정상 CO 및 $CO_2$ 생성특성은 적절히 예측하지 못함을 확인하였다. 이러한 결과는 최근 수행된 유사조건의 정상상태 환기부족 구획화재에 대한 FDS 예측결과와 상반된 것으로서, 반밀폐된 구획화재 모델링에서 FDS를 이용한 비정상 CO 생성특성 예측에 상당한 주위가 요구됨을 확인하였다.

  • In recent years, the number of cases caused by people such as forest fires has been increasing, so it is very important for the whole nation to prevent and practice forest fires. In addition, due to climate change around the world, many lives and disaster losses are increasing due to forest fire-related disasters, and in the last 10 years (2014-2023), there have been 5,668 forest fires and 40,037 hectares of damage, which is equivalent to 56,000 football fields, resulting in 19 casualties and 285.4 billion won in damages. Now, in order to improve the understanding and awareness of forest fires among all the people, the government should actively inform the people about how to act in the event of a forest fire by making the people's action tips related to forest fires easy to understand and practical through public relations activities. In addition, the public and the government should work together to prevent and prepare for forest fires before they occur.

  • The hazard assessment in which the potential hazard factors In the buildings are investigated and the scale of the hazard is analyzed should be performed first in order to prevent personal and material damages due to building fire. In this study, the building fire hazard are assessed using 822-item checklist, for the qualitative evaluation of which the main factors are classified into 10 items, yielding 100 scale points with some weighting. It is shown that present model is applicable for the assessment of all general buildings through the examination of the suitability of assessment model by actual assessment of existing building. Also, the checklist is prepared in itemized questionnaire form for easy assessment of building fire hazard. Therefore, the present model will be helpful for those working in fire prevention, who are suffering from the lack of manifest evaluation model for the fire prevention assessment so far in Korea.
