국내 건축물들이 다양한 변모를 보이면서 화재안전을 위한 성능설계가 도입되고, 화재 영향평가제도와 화재위험성평가제도가 시행되고 있지만 이러한 방재관련 특별법에 대한 방법론이 미비한 실정이다. 따라서 본 고에서는 국내보다 앞서 성능설계를 도입하여 시행하고 있는 일본의 동경소방청 화재피난시뮬레이션(FEA)을 국내 성능설계의 방법론으로 적용시키기 위하여 FEA를 중심으로 국내에서 범용적으로 사용되고 있는 SIMULEX와 EXDOUS를 활용하여 사례분석을 통한 각 시뮬레이션의 특징에 따른 차이점을 분석하고 FEA의 한국 적용방안에 대한 기초자료로 제공하고자 한다.

2002년 7월 1일부터 시행되는 제조물 책임법에 대비하여 기업에서 준비하여야 하는 사항중에 가장 어려움을 느끼는 부분중의 하나가 제품의 안전성 평가 부문이다. 제품의 안전성 평가는 과거의 성능검사나 특성검사가 아니라, 사용자의 오사용으로 야기될 수 있는 위험성의 평가까지도 고려하여야 한다. 이에 대표적인 정량적 안전성 평가기법인 FTA(Fault Tree Analysis)를 사용하여 전기 밥솥에 대한 정량적 평가를 실시하여 보았다. 전기밥솥에서의 잠재위험 중 가장 피해가 클것으로 생각되는 화재를 정상사상으로 하고 이에 대하여 m.cutset 분석과 빈도분석 등을 시행하여 제품안전성평가의 과정과 분석방법들을 설명한다.(중략)

Demand for hydrogen as a renewable energy resource is increasing. However, unlike conventional fossil fuels, hydrogen requires a dedicated refueling station for fuel supply. A risk assessment of hydrogen refueling stations must be undertaken to secure the infrastructure. Therefore, in this study, a risk assessment for hydrogen refueling stations was conducted through both qualitative and quantitative risk assessments. For the qualitative evaluation, the hydrogen dispenser module was evaluated as two nodes using the hazard and operability (HAZOP) analysis. The risk due to filter clogging and high-pressure accidents was evaluated to be high according to the criticality estimation matrix. For the quantitative risk assessment, the Hydrogen Korea Risk Assessment Module (Hy-KoRAM) was used to indicate the shape of the fire and the range of damage impact, and to evaluate the individual and social risks. The individual risk level was determined of to be as low as reasonably practicable (ALARP). Additional safety measures proposed include placing the hydrogen refueling station about 100m away from public facilities. The social risk level was derived as 1E-04/year, with a frequency of approximately 10 deaths, falling within the ALARP range. As a result of the qualitative and quantitative risk assessments, additional safety measures for the process and a safety improvement plan are proposed through the establishment of a restricted area near the hydrogen refueling station.

Leakage incidents due to the fault of hazmat tank foundations are likely to cause the tremendous fire disaster in the national industry cluster area. The proper design and construction of tank foundation should be required to prevent the tank fire. In the study, the types of typical tank foundations were classified and modeling the individual tank type for 3D FEM analysis was performed to suggest the guideline for the design and construction of tank foundations. Matters to be attended of the foundation design and construction are reviewed through the comparison assessment of the numerical analysis results of the foundation types.

With the increased interest in reducing air pollution, supply of natural gas for gas vehicles is increasing. Thus, the number of establishments of LNG and CNG stations is increasing as well. However, due to major gas accidents such as the fire and explosion accident of a Bucheon LPG station in 1998, it is difficult to establish a new station. In this research, we conducted qualitative hazard analysis fer LCNG/LNG multi-station by using the K-PSR method and proposed recommendations for hazard mitigation.

From the viewpoint of fire-fighting activities, public building have structural and management problems in fire, so evacuation disturbance and risk of expanding combustion are high. As a result of analyzing various fire fragile factors of public building, The evaluation areas were derived from safety systems, fire-fighting facility, structure safety, general safety and the evaluation factors were presented. Also, the characteristics of domestic and foreign certification systems were analyzed by comparing and analyzing the status of fire safety performance certification system for 6 domestic and overseas apartment houses. In conclusion, the 5 convergence directions of certification system and 22 evaluation items by 4 evaluation fields were derived, and based on this, we have established 3 convergence introduction plans of fire safety performance certification system of public building.

In this study, we would evaluate fire risk by domestic standard for artificial turf installed on field and roofs. Today domestic regulation for artificial turf only applies to outdoor uses and especially KS M 3888-1 has compulsion but limited to school athletic facilities. Indoor regulation complying with National Emergency Management Agency (No. 2012-35) was enacted as recommendations. Thus this study did combustion test of artificial turf installed on field. Analyzed result by 45 degree flammability test, standard was inadequate to judge the fire risk so we compared and analysed its characteristic through combustion test of flame retardant finishing carpet used as flooring. Test and assessment result of its ignitionability by 45 degree flammability test showed that carpet was satisfied with flame retardant finishing performance standard contrary to artificial turf. For this reason, by conducting cone calorimeter test, the combustion property after ignition would be analyzed and evaluated and then this study will suggest a countermeasure for strengthening standard.

This paper evaluates the fire safety level of eight pump rooms in the nuclear power plant using a fire model, CFAST We estimate the Conditional Core Damage Probability (CCDP) of each room based on the analyzed results of CFAST Eight rooms located on the primary auxiliary building of the nuclear power plant are high pressure safety injection pump room A/B, low pressure safety injection pump room Am. containment sprdy pump room A/B, and motor-driven auxiliary feed water pump room A/B. The upper layer gas temperature of each room is estimated and the integrity of cable is reviewed. Based on the results, the integrity of the cable located at the upper part of compartment is maintained without thermal damage. The Conditional Core Damage Probability Is reduced to half of the old values. Accordingly, the fire safety assessment for eight pump rooms using the fire model will be capable of reducing the uncertainty and to develop a more realistic model.
