  • 산불로 인한 피해는 비단 산림뿐만 아니라 산림인접지 가옥, 사찰과 같은 건축물에서도 발생된다. 특히, 사찰은 국보뿐만 아니라 다양한 문화재를 보유하고 있어 산불로 인해 소실될 경우 문화 자산의 피해가 불가피하다. 이에 국보보유사찰, 문화재 다량보유사찰, 조계종 교구 본사, 세계문화재 등재 사찰 등을 포함한 우리나라 주요사찰 42개소에 대해 미국 Firewise 및 캐나다의 Firesmart에서 제시한 산림인접지 시설물의 위험성 평가 방법을 기반으로 체크리스트 기법을 이용하여 '사찰 산불 위험성 평가'를 실시하였다. 체크리스트 주요 항목은 크게 입지 여건, 임상 및 산림과 사찰의 이격거리, 산불발생 개연성, 사찰 주변 가연물 화재위험성, 적정소방시설 여부, 기타 화재방지를 위한 시설물 평가 등 총 6개 항목으로 구분하여 26개 세부항목을 작성, 평가하였다. 정성적 위험성 평가 결과, 산불로 인한 화재 위험성이 높은 사찰과 산불피해 저감 대책을 제시하였고 향후, 정량적 위험성 평가를 통한 위험관리 모델 제시에 관한 연구를 수행하고자 한다.

  • Diverse and complex facilities have been on the increase in urban areas in accordance with rapid urbanization. Along the lines of the increase in facilities, the risk of fire has increased. In particular, fire accidents as well as traffic accidents accounted for the highest rate in artificial disasters. Therefore, the National Fire Information Systems managed by the National Emergency Management Agency (NEMA) appeared for the effective fire management. The NEMA has provided the public with the Internet services regarding information about fire outbreak since 2007. This study acquired data from both NEMA and the Jinju City Fire Department. It constructed the fire data of Jinju City and calculated the change in spatial density targeting fire, occurred in Jinju city with a view to examining the fire risk of facilities by conducting a time series analysis on the trends of fire outbreak over a span of periods between 2007 and 2013. It also conducted an analysis of Moran's I, Getis-Ord Gi. Therefore, it came to select higher hot spots in terms of fire location and fire density. In addition, it attempted to calculate the levels of fire hazard by drawing up the matrix of personal injury and property damage, depending on facilities to present the methods, which can predict the risk of fire occurrence in urban areas.

  • In Korea, performance-based fire safety designs are being discussed to deal with the various risks of fire in complex and diverse types of structure. However, performance-based fire safety designs are not actively employed because it is difficult to estimate the fire characteristics related to the various factors in buildings. In this study, real scale fire tests were conducted based on fire severity levels and fire loads provided in He New Zealand Building Code, in order to use the results as guidelines and fundamental data for performance-based designs. In the real scale fire tests conducted in a 10MW full-scale calorimeter, wood cribs were placed in a $2.4(L){\times}3.6(W){\times}2.4(H)m$ mock-up of a compartment which had one $0.8(L){\times}2.0(H)$ opening for different fire loads and heating was continued until all of the wood cribs were burned down. The heat release rate started to increase rapidly 90 seconds after the wood cribs caught fire. In the test with a fire load level 1, the maximum heat release rate of 4743.4 kW was reached at 244 second. In the test with fire load level 2, a maximum heat release rate of 5050.9 kW was reached at 497 second. In the test with fire load level 3, a maximum heat release rate of 4446.9 kW was reached at 677 second.

  • The purpose of this study is to present the most effective smoke exhaust mode by comparing the quantitatively evaluated risks according to the smoke exhaust mode when a train fire occurs in a subway platform. Therefore, applying the typical subway platform as a model, train fire scenarios are developed with the evacuation start time and location of the fire train for each exhaust mode. The fire accident rates (F) are calculated and the number of fatalities (N) was quantitatively estimated by fire analysis and evacuation analysis for each scenario. In addition, the F/N curve compared with the social risk assessment criteria and the following conclusions were obtained. In the event of a train fire at the subway station platform, the evacuation must start up within 600 s in maximum to ensure the evacuees' safety. To secure evacuation safety, it is advantageous to operate the HVAC system of the platform in the air-supply mode at station without TVF. Comparing the F/N curve for each exhaust mode with the social risk criteria, it turned out that the risk significantly exceeds the social risk criteria in case of no mechanical ventilation. As a result, this paper shows that the ventilation mode in which TVF are exhausted and HVAC system is operated in the pressurized mode are the most effective smoke exhaust mode for ensuring evacuation safety.

  • 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.

  • After train fire accident in Daegue, many research on train fire safety improvement have been carrying out. Since many alternative fire safety measures can be applied in our railway system, the effect of the each safety measure must be quantified prior to the safety investment. In order to estimate the effects of each safety measure quantitatively, fault trees and event trees are constructed in this study. Results can be applied for cost-benefit analysis or sensitivity analysis for safety measures in risk assessment process.

  • 세계의 모든 나라가 화석연료를 대체하는 태양광, 풍력 등의 그린에너지 기술개발에 주력하고 있으며, 한편으로는 에너지의 효율제고 및 재생을 위하여 폐기물로부터의 자원순환을 이룩하는 폐기에너지 회수에도 많은 노력을 기울이고 있다. 그 하나의 방편이 버려지는 쓰레기에서 에너지를 회수하는 고형재생연료인 RDF(생활폐기물 고형연료 제품, Refuse Derived Fuel) 생산이다. 우리나라에서는 유일하게 강원도 원주시에서 하루 80톤을 생산하고 있으며 아직은 기술도입 초기단계에 있는 가연성폐기물의 연료화 기술이다. RDF의 특성은 불연성 성분이 제거된 일반 가연물을 분쇄하여 압출성형 가공한 펠릿형상의 고체연료로서의 열적 특성이 우수하나 화재안전 측면에서는 제조 및 취급공정에서의 일반적인 가연물 화재위험성을 가지고 있고, 저장과정에서는 축열발열에 의한 자연발화 위험성이 상존하며, 저장형태, 특히 사이로의 경우 구조특성으로 인하여 화재진압도 쉽지않다. 본 논문에서는 일본의 RDF 화재사례를 중심으로 그 화재 위험 특성과 안전대책을 고찰하고자 한다.
