Performance based design is a recent evolutionary step in the process of designing fire protection systems. In essence, it is a logical design process resulting in a solution that achieves a specified performance. Sometimes the prescriptive solutions presented in various codes and standards are too expensive or inflexible. Often the solutions do not and enables optimization of a solution for cost and function. In this study, performance based design was carried out to determine the extent of passive fire protection for oil terminal facilities. The results of performance based design were compared with those of prescriptive code based design. Performance based design is not always more economic than prescriptive code based design but provides more reliable and effective design that is fit for the purpose.

Welding and cutting, which are representative tasks in handling firearms at industrial sites, are the basis for production and maintenance processes across all industries. They are also essential in the root industry. Specifically, they are widely used in the manufacturing industry, including equipment industries such as shipbuilding, automobiles, and chemicals, and subsequent maintenance work and general facility repair. However, such hot work carries a high fire risk owing to sparks scattering and inadequate management, resulting in a high occurrence of accidents. In response, the government and relevant organizations have recently revised the Occupational Safety and Health Act to prevent accidents during hot work. These revisions impose more stringent regulations than before, which are expected to help prevent actual fire accidents. However, whether the fire observer system, which is the core element of the revision, would be practically applied and maintained is unclear. Therefore, this study compared the fire observer system in the revised Occupational Safety and Health Act with those in the laws and systems of developed countries, conducted interviews with safety and health experts to assess the suitability of the new system for fire observer operations, and improvement plans were derived accordingly. Therefore, the laws and systems of developed countries grant more authority to fire observers compared with those of Korea. Moreover, professional training in handling emergency is required. Interviews with safety and health experts revealed that regardless of company size, the same operating standards were applied, and standards for deploying fire observers in various locations were unclear. Furthermore, there was a lack of professional education and training, and the role and authority of fire observers were limited. These findings revealed a problem in this sector. The results of this study are expected to serve as basic data for establishing a practical system for placing fire observers and supplementing laws, guidelines, and systems for preventing fire accidents.

To minimize and prevent the increasing fire and personal injury, the domestic firefighting organizations are making continuous efforts to strengthen the response system and safety standards. "Fire Reduction Program" has been prepared to reduce the outbreak of fire up to 20% in the next 10 years, and the analysis of fire sources should be done and its countermeasures also should be done accordingly. Therefore, the management status, the improvement tasks, and the limitations of the implementation plan are reviewed and studied so that the implementation and goal of the "Fire Reduction Policy" can be achieved.

The purpose of this study is to enhance heat insulation effect and to decrease fire hazard by attaching aluminum foil to expanded polystyrene, which is mainly used for insulating materials, to have fire retardant. The result of the test confirmed that the insulating materials, expanded polystyrene of $10kg/m^3$ and $14kg/m^3$ of density attached aluminum foil on both sides, showed 12%, 14% of improved heat transfer coefficient respectively compared to existing expanded polystyrene of the same density. Besides, they met all the standards for the testing of heat release and gas hazard. On the other hand, the one made of general expanded polystyrene could not meet the standards of the heat release test and the gas hazard test.

The public relations room of the waste disposal facility is a space that can be visited by a large number of unevaluated personnel. Therefore, it is essential to design against fire, and research on fire and evacuation is essential. In this study, in order to evaluate the safety of the occupants in the event of fire and evacuation based on the life safety standards of occupants, the increase in risk due to heat, visible distance, and toxic gases on a plane 1.8m from the floor, which is the limit of breathing of the evacuee, over time. It was analyzed by location. As a result, the RSET of the P-01 exit was 93.0 seconds and the ASET was 272.6 seconds, the RSET of the P-02 exit was 45.8 seconds, the ASET was 147.7 seconds, the RSET of the P-03 exit was 106 seconds, and the ASET was 182.9 seconds.

In the recent years, the high strength concrete has increasingly been used according to extending market of tall buildings. However, Ministry of Land, transport and Maritime Affairs was established by law with an alternative plan after June 2008 because of the weakness of high strength concrete accompanied spalling phenomena in fire. The mix design of concrete has to properly meet standards which are the spalling resistance of concrete and limited temperature of steel reinforcement. The fire proof concrete mixed fiber has widely been used to meet spalling safety on the many construction sites, the most researches about the fire proof concrete mixed fiber had being carried out focused on fire resistance, compressive strength and cast in place of concrete. But the most important thing is column shortening used the fire proof concrete within the vertical members. In this paper, the fire proof concrete filled spalling safety standards was experimented by required material when the column shortening is revised between normal concrete and fire proof concrete mixed fiber and then the results have done a comparative analysis. Also, The paper aimed to indicate a basic data for revision of column shortening of fire proof concrete.

STCW 협약 A-VI에 의거, 승선 필수 증서를 발급받기 위해 소화 과정 최저 훈련 이수를 거치게 되는 공간이 수소화 훈련장이다. 선박 화재의 상황과 유사한 장소에서 발생한 화재 진압 훈련을 위한 실습 장소의 특성상, 재실자의 안전을 보장할 수 있는 운영을 위해 안전성을 수치화하여 평가하고 기준을 수립하는 연구의 필요성이 대두되었다. 화재 안전 평가를 위해 FDS를 기반으로 한 Pyrosim을 활용하여 제연설비 유무에 따른 Case를 설정, vector의 분석을 통한 연기 유동 및 열기에 대한 평가를 수행하였다. 피난 안전평가는 Pathfinder를 통해 허용 피난시간, 총 피난시간을 수치화된 결과로 해석, 비교하여 안전성을 분석하였다. 각 Case에 대한 안전성을 평가함으로 제연설비별 기능의 적정성을 수치, 시각적으로 나타내었으며, 현재 운영 상태는 안전성이 양호한 것으로 평가하였다. 집진설비가 정지한 비상상황은 각 피난시간과 111.2초의 여유시간으로 나타내어 수소화 훈련장의 비상상황에 대한 피난시간의 기준으로 활용할 것을 제시하였다.

농어촌 민박 이용객의 증가와 정부의 관련 정책에 대한 다양한 지원이 이루어지고 있다. 그러나 농어촌 민박의 숙박 서비스에 대한 안전기준이나 안전지표가 부족하여 2018년 12월 강릉 펜션 일산화탄소 누출사고, 2020년 1월 동해 펜션 가스폭발사고 등 대형사고가 발생하고 있으며 국민의 안전을 위협하고 있다. 숙박업소와 달리 농어촌 민박의 경우 소화기와 화재경보기 등의 일정 요건을 갖추면 영업이 가능하도록 되어있다. 농림축산식품부는 농어촌 민박 제도개선 대책으로 농어촌정비법 개정을 통해 가스와 전기안전 전문가가 안전점검을 하고 그 확인서를 제출하는 제도를 도입하고 있다. 본 연구의 목적은 농어촌 민박의 숙박시설에 대한 안전기준과 안전지표를 제시하여 농어촌 민박과 관련한 지방자치단체와 정부의 운영관리와 점검에 필요한 기준을 제시하는 데 있다. 숙박시설의 안전관리는 국민의 가장 기본적인 안전과 직결된다. 따라서 농어촌 민박에 대한 적절한 안전기준을 제시하고 신고필증을 배부할 필요가 있으며 지속적인 수시점검과 안전교육 및 소방, 질식사고 등에 대한 사전예방을 위한 대책을 세울 필요가 있다. 본 연구를 통해 농어촌 민박의 안전관리 실태에 대한 조사와 분석 결과를 바탕으로 안전관리 기준 및 안전지표, 수시점검 방법, 사고예방 교육을 제공하고 제도화 할 필요성이 있는 것으로 나타났다. 농어촌 민박의 숙박이용 국민에 대한 안전확보를 위해 반드시 안전관리 기준과 교육을 제도화하는 것이 시급한 것으로 보인다.
