The flash point and the AIT(auto-ignition temperature) are the most important combustible properties used to determine the potential for the fire and explosion hazards of flammable material. In order to know the accuracy of data in MSDS(Material Safety Data Sheet), the flash point of n-acids were measured by using Pensky-Martens closed cup tester(ASTM D93), Setaflash closed cup tester(ASTM D3278), Tag open cup tester(ASTM D1310) and Cleveland open cup tester(ASTM D92). Also, the AIT of n-acids were measured by using ASTM E659-78 tester. The measured the flash points and the AIT were compared with literatures and MSDS in KOSHA. The measured the flash points and the AIT were different from those in literatures and MSDS. Therefore, This paper shows that it is needed to investigate the MSDS compatibility of n-acids for the fire safety objectives.

바이오디젤은 식물성기름등으로부터 제조시 메탄올과의 반응으로부터 제조되므로 바이오디젤의 잔존 메탄올은 화재폭발위험성을 높일 수 있다. 바이오디젤에 존재하는 메탄올의 위험도를 측정하기 위하여 바이오디젤에 메탄올을 일정 비율로 첨가하여 인화점과 동점도를 측정하였다. 바이오디젤의 인화점은 메탄올의 증가에 따라 현저히 감소하였으며 동점도도 감소하는 것으로 나타났다. 실험결과 바이오디젤 연료에 반응물 메탄올이 잔존하거나 또는 연료의 점성을 낮추기 위하여 첨가되는 메탄올은 바이오디젤의 인화점을 낮추어 화재폭발 위험성이 높은 것으로 나타났다.

본 연구에서는 알루미늄(Al), 아연(Zn)이 단일 성분으로 존재하는 경우의 폭발위험성이 Al-Zn혼합물 분진에 비하여 어떻게 변화하는지를 알기 위하여 폭발하한농도(LEL), 최대폭발압력($P_{max}$)등에 대한 폭발특성을 실험적으로 조사하였다. 그 결과 Al은 Zn의 혼합에 의해 폭발하한농도(LEL)가 급격히 증가하고 최대폭발압력이 감소하였으며, Al-Zn혼합물의 폭발위험성은 단일 성분의 Al에 비하여는 낮지만 Zn 단독의 경우보다는 높은 것을 알수 있었다. 그러므로 Zn-Al혼합물이 Al보다 폭발성이 낮아지지만 화재폭발 가능성이 충분히 잠재되어 있으므로 예방대책이 필요하다.

A squid gill-net fishing vessel Jayueoroho which was being insured ITC-Hulls and was laid up long period illegally under the condition of unmanned in the Pert of Kamcheon. On 30, March, 1993, the fishing vessel moved out toward the high sea by assistance of two tugboats, 12 miles southeast from Teajongdae, to discharge sewage. At that time the shipowner, the skipper, chief engineer and two labourers were boarding, and a fire was broken out by electric leakage at sea. For all their efforts of fire-fighting operation the fishing vessel foundered with explosion. In this case, she had been breached the warranties of legality, especially Korean maritime acts concerned, and the warranties of seaworthiness(MIA 39(5)) as attributable cause because of unmanned on board by wilful misconduct of the insured. Therefore it is prima facie evidence that the insurer is not liable for any loss attributable to the wilful misconduct and breach of warranties of the insured in MIA 1906.

In this study a board was made with good fireproof materials of which test was conducted according to the fireproof test for KS F 2257 construction members, and the temperature in coated steel which has a possibility to explode with concrete surface was measured. It is not appropriate to use normal mortar or mortar covering mixed with P.P. fiber to take a measure to prevent the explosive splalling of high-strength concrete. To finalize an Al-Si (aluminosilicates) board-requires over 30mm in thickness at the minimum for the required fire resistance performance and explosion prevention.

The Flash Point is one of the most important combustible properties used to determine the potential for fire and explosion hazards of chemical materials. An accurate knowledge of the flash point is important in developing appropriate preventive and control measures in industrial fire protection. The lower flash points for the Water + n-Propanol systems were measured by using Pensky-Martens closed cup tester. The experimental data were compared with the values calculated by the laws of Raoult and van laar equation. The calculated values based on the van Laar equation were found to be better than those based on the Raoult's law.

The safety of LPG vessel storage has been simply designed and controled with blast wave barrier structure concept regardless of its quantity or hazardous situation. The limit of regal controls on LPG vessel storage need to be identified in terms of safety buffer distance from LPG explosion. The level of overpressure effect and heat radiation In the safety structure and neighbouring human activity required to be estimated to find the gap between existing controls on such storage. To this content the paper discuss the issues on the approach In the blast wave barrier and safety separation distances.

In this study, the fire resistance performance of polymer cement mortars which are used as a representative repair material for section restoration, is evaluated and residual bond strength is measured by considering unity with concrete. According to the evaluation of fire resistance performance of re-emulsification type polymer cement mortars, residual compressive strength was drastically decreased according to heating temperatures with an increase of polymer addition rate, and this seems to be attributable to the application of polymer film. In addition, an explosion phenomenon occurred frequently with an increase of addition rate, so this should be considered when selecting repair materials and processing.
