본 연구는 국내외의 소방용품 내용연수 제도와 소방안전관리자 인식조사를 바탕으로 소방용품 내용연수 제도화에 대한 정책 방안을 제시할 목적으로 실행되었다. 이를 위하여 일본, 미국, 한국의 소방용품 내용연수 제도를 분석하여 권장 내용연수를 도출하고, 전국 17개 시도권역 소방안전관리자 660명을 대상으로 소방용품 내용연수 제도화 필요성, 32종의 소방용품의 내용연수 관리 및 향후 정책 방향에 대한 인식 조사 결과를 분석한 후 소방용품 내용연수 정책실행 방향을 찾고자 하였다. 소방안전관리자 설문 조사 결과, 소방용품 법제도화에 대하여 79.3% 소방안전관리자가 찬성하였으며 소방용품 품목별 제도화 필요성에 대해서는 분말소화기(77.3%), 감지기(44.6%), 소방호스(44.4%), 가스계소화기(40.6%), 완강기(36.2%), 유도등(35.9%), 공기호흡기(35.9%), 주거용주방자동소화장치(33.9%), 자동확산소화장치(33.9%), 비상조명 등(31.2%), 가스누설경보기(30.7%) 등이 30%를 상회 수준으로 내용연수 관리가 필요하고, 특히 분말소화기(60.0%), 감지기(20.0%), 소방호스(18.8%)는 최우선 도입이 필요하다고 인식하였으며, 소방용품 내용연수는 대부분 10년 전후 경과하면 교체해야 한다고 인식하고 있었다. 따라서 이러한 결과를 토대로 내용연수 제도화 소방용품 품목을 선정하고 단계적 정책 도입방안을 제안하였다.

In this study, the height of the flame required to estimate the heat flow path and flame spread in pool fire has been applied by the empirical formula, but it is calculated without applying the pressure and temperature parameters of the fire room. Until now, the height of the flame applied to pool fire was $l_F=0.235Q^{2/5}-1.02D$ in the Heskestad empirical formula, but accurate temperature calculation was not possible due to the temperature and pressure which are not influenced by the flame height. Therefore, applying the temperature and pressure around it can calculate the exact flame height, which can be applied to fire investigation and fire dynamics. The structure of the flame is divided into a continuous flame, an intermittent flame, and a buoyancy flame, but it is assumed that the flame height is calculated from the visual aspect to the intermittent flame region, and the temperature of the buoyancy flame is very low. The effect of heat of vaporization on the height of flame was investigated. The results showed that flame height was different according to the pressure and temperature around the fire room.

Even though the interior of urban transit vehicle has been changed as a preventing measure against fire to make it inflammable, there remains a possibility of fire breaking out in case of gasoline etc being brought in the subway. However, there is also the possibility that in case if fire toxic gas is generated and hot air spreads in carriage it will prove very dangerous for people sitting inside. This is a comparative study where we compare simulation results with model examining the time and direction the fire spreads when it breaks out. Also there is vertical distribution of temperature in carriage where the fire spreads out. This study is about demonstrating how to establish smokeless system in urban vehicle, about its necessity, and about vehicle system restructuring. This study also makes an effort to find more advanced method for efficient fire safety in trains. In existing vehicles, in case of fire, the smoke can't go out when doors are closed and hence it spreads in whole train. Even though the method of using ventilation or exhaust established inside the carriage to throw smoke out is much better than the way of opening end doors in each carriage, this study is trying to do research on second way. Through simulation we see that in second case, even though not as good as the first one, smoke can exit through gates. Even though the first method is better, the second can also be uses to let fire out. We can know that in the first case as the smoke can exit out faster, it provides more safety for people. So this system provides better fire safety condition.

The Fire Dynamics Simulator (FDS) was applied to a center fire in a room, of which dimensions were 1.8m${\times}$1.38m with an opening of 0.45m${\times}$1.2m doorway, to evaluate the numerical method. The time-variation of temperature at a top point of thedoorway centerline and distributions of evaluate the numerical method. The time-variation of temperature at a top point of the doorway centerline and distributions of average temperature along the doorway centerline and corner stack were compared with measurements for three different fire sizes, 7.65, 21.25 and 51.71kW. The results showed FDS predicted a very rapid fire growth compared with the experiment for all the three fire sizes, that is an importand shortcoming of FDS in compartment fire simulations. The average temperature distributions, and heights of hot gas layers and neutral planes in steady state were in reasonable agreement with the measurements.

부산 실내사격장 화재의 원인을 추정하고 화재안전대책을 강구하기 위해 화재 시뮬레이션과 사격장 화재의 사례조사를 수행하였다. 현장조사와 잔류화약 분말에 대한 사격시험도 실시하였다. 총구불꽃과 탄자 받이에서의 스파크의 흔적이 CCTV 녹화영상에 나타나지 않았고, 유탄의 충격에 잔류화약이 점화하지 않았다. 따라서 잠재적 점화원 중 담뱃불이 가장 유력한 점화원으로 추정되었다. 또, 사격실에서의 폭발원인은 폴리우레탄 흡음재와 흡음재에 축적된 잔류화약 분말의 격렬한 연소 때문으로 판단되었다. 한편, 실내 사격장의 안전대책으로 프로파일 폴리우레탄 흡음재의 사용금지, 잔류화약 제거와 철저한 관리, 탄자받이의 강구조물 제거 등이 필요하다.

최근 가연물이 있는 장소에서 용접·용단 작업 중 불꽃 비산 등으로 인한 화재·폭발사고가 빈발하고 있으며, 이러한 화재사고의 원인은 위험물 제거, 불꽃 비산방지 조치 등 기본적인 안전수칙 미준수가 대부분으로 산업안전보건법의 제도적인 보완이 필요하다. 본 연구에서는 국내 용접·용단 작업 등 화기작업에서의 화재·폭발 사고를 시스템적 관점에서 분석하고 그 결과를 반영하여 화재감시자 배치 확대, 화재위험작업의 사전승인, 화재예방 안전교육 강화 등 제도개선방안을 제안하였다.

Analysis on the study for the sodium fire mitigation was carried out using the CONTAIN-LMR code. Sodium loop building was partitioned into the many cells, in which the safety venting systems were installed for the purpose of improving the sodium fire safety and minimizing its effect on the sodium loop building. The effects of sodium fire on sodium loop building partitioned into the many cells and not partitioned were investigated. The peak pressure and temperature of each cell accompanied by sodium fire in sodium loop building partitioned were lower than those of sodium loop building not partitioned. In the case of partitioning sodium loop building, the pressures, temperatures and aerosols into cells were transferred through propagation path of CONTAIN-LMR sodium fire model simulated by this study, and the effect of sodium spray fire on sodium loop building was mitigated by partitioning building. In addition, the excessive rise of pressure into cells was prevented by installing the over-pressure exhaust valve and under-pressure exhaust valve on the flow path between cells.

In the case of the fire to the exterior of the building through openings, the openings of the adjacent building are exposed to the risk of combustion expanding and factors that affect the combustion in the radiant heat and direct flame. Recent five years, fire of the adjacent building indicated that incidence of the 5,134(2.27%) among total 225,934 cases occurred The damage scale of fire expanded was lower than in a single building but casualties(5.46%) and property(25.0%) damage were higher. Therefore, this study provides to analyze the operating status for fire protection equipment of fire-preventing area in the Seoul and to apply measures to improve fire protection equipment according to narrow the distance between the building openings studied.

본 논문은 아파트 화재에서 재실자의 피난안전성을 제고하기 위한 목적으로 수행되었다. 이를 위해 대전광역시 유성구에 위치한 183개 아파트 단지의 3,056개 피난계단 층을 대상으로 현장 조사를 실시하였으며, 입주민 183명을 상대로 소방안전교육경험, 피난계단에 대한 안전관리인식, 그리고 소방안전인식에 대한 설문조사하였다. 조사결과, 연구대상물 3,056개 피난계단 층 중 1,916층에 장애물이 방치되어 62.7% 장애물 형성율을 나타내었다. 소방안전교육 경험은 연구대상자의 83.10%가 있는 것으로 나타났다. 연구대상자의 피난계단에 대한 안전관리인식은 평균 $3.84{\pm}0.75%$를 보였으며, 소방안전인식은 평균 $3.49{\pm}0.61%$을 나타냈다. 결과적으로 연구대상자는 대부분 소방안전교육을 받았고, 피난계단의 안전관리에 대한 방법은 이해하고 있지만, 안전관리에 대한 행동의 실천은 낮은 것으로 나타났다. 본 연구결과를 바탕으로 한 정책적 제언은 피난계단의 안전관리에 대한 인식이 행동의 실천으로 이루어질 수 있도록 소방안전교육을 정기적으로 받을 수 있는 사회적 제도와 그 교육에서 피난계단의 관리에 대한 교육내용이 강조되어야 한다.
