The numerical investigation on the effects of water-mist characteristics has been carried out for the fire suppression mechanism. The FDS are used to simulate the interaction of fire plume and water mists, and program describes the fire-driven flows using LES turbulence model, the mixture fraction combustion model, the finite volume method of radiation transport for a non-scattering gray gas, and conjugate heat transfer between wall and gas flow. The numerical model is consisted of a rectangular enclosure of $L{\times}W{\times}H=1.5{\times}1.5{\times}2.0m^3$ and a water mist nozzle that be installed 1.8 m from fire pool. In the present study, the parameters of nozzle for simulation are the droplet size and the spray velocity. The droplet size influences to fire flume on fire suppression more than the spray velocity because of the effect of the terminal velocity. The optimal condition for fire suppression is that the droplet size and the spray velocity are $100{\mu}m$ and 20 m/s respectively.

Purpose: Swimming industry is improving faster than the other types of sport industries and populations of participating swimming are promptly increasing. Lack of recognition of fire safety in swimming facilities is issues related-studies has only recently begun to pay attention. This study is to review and extract fire safety factors for managing swimming pool. Research design, data, and methodology: The study reviewed related-ordinances, governmental documents, and studies discussing safety management of sport facility. Given the literature review, the study produced an initial construct presenting items and factors including fire safety elements and experts' review were conducted to ensure conceptual validity. Finally, the study generated the final factors and subitems representing fire safety elements for swimming pool management. Results: The study confirms factors and elements as follows: the study identifies fire safety equipments as first factors presenting fire extinguisher' place, its proper run, check list and so forth, Second factor is warning system including fire warning equipment, its proper operation, sprinkler and its proper operation, switch and lamp of emergency panel and their proper run and so on. Third factor is evacuation system including a fire exit, exit sign, broadcasting equipment, and their proper operation, and so on. The other factors are an electronic equipment and its subelements, gas management including safety management of LPG, gas valve, pipe, and fire prevention facility including a fire door and its proper operating. Conclusions: Regarding safety management of swimming pool, further discussions and implications were made, and future directions for related-studies were discussed.

Sphere anemometry technique is re-visited for low gas velocity measurements during full-scale fire tests. This technique has the advantage of requiring only one channel per sphere for data acquisition, in addition to being cheap and rugged, The results indicate that the technique is useful for small fuel load burns with low radiation levels. For large fuel loads, the usefulness is up to sprinkler activation temperatures.

The energetic and environmental problems have been getting serious after the revolution of modern industry. Therefore, demand of gas as an eco-friendly energy source is increasing. With the demand of gas, the use of gas is also increased, so injury and loss of life by the fire have been increasing every year. Hence the influence on flame caused by Vapor Cloud Explosion in enclosure of experimental booth was calculated by using the API regulations. And the accident damage was estimated by applying the influence on the adjacent structures and people into the PROBIT model. According to the probit analysis, the spot which is 5meter away from the flame has nearly 100% of the damage probability by the first-degree burn, 27.8% of the damage probability by the second-degree burn and 14.5% of the death probability by the fire.

본 연구의 목적은 화재사고가 발생한 건물에 인접한 LPG 탱크용 방화벽의 적용성을 검증하는 것이다. 제안된 방화벽 재료는 (1) 두께 10 mm 목재합판, (2) 내화도료를 도포한 목재합판, (3) 두께 75 mm Expanded Polystyrene, (4) 두께 75 mm 유리섬유 충진 샌드위치 판넬, (5) 두께 75 mm Autoclave Lightweight Concrete이다. 화원은 1 m 정사각형으로 120-140 g/s의 LPG를 균일하게 분사하여 방화벽과 후단의 탱크를 가열한다. 적용성은 시험 후 방화벽의 구조적 건전성 확인, 방화벽 양면 및 탱크표면 온도, 탱크 인근 복사열을 분석하여 판단한다. 그 결과, ALC 방화벽이 유일하게 구조 건전성을 유지하였고 저장탱크 온도를 가작 적게 상승시켜 폭발 방지 적용성을 확인하였다. 본 실험결과를 활용하여 방화벽의 성능평가 기준 마련에 필요한 핵심인자를 도출하였다.
