The explosion limit is one of the major combustion properties used to determine the fire and explosion hazards of the flammable substances. The explosion limit of organic acids have been shown to be correlated the heat of combustion and the chemical stoichiometric coefficients. In this study, the lower explosion and upper explosion limits of organic acids were predicted by using the heat of combustion and chemical stoichiometric coefficients. The values calculated by the proposed equations agreed with literature data within a few percent. From the given results, using the proposed methodology, it is possible to predict the explosion limits of the other organic acids.

Jet fire, pool fire, and vapor cloud explosion are major accident scenarios in LPG filling station. The protection wall would mitigate radiation effect in a jet fire. In case of a pool fire, the protection wall would restrict expanding the pool area. The protection wall might both obstruct the dispersion of released vapor and protect blast overpressure in a vapor cloud explosion scenario. In this paper, An availability assessment method of the protection wall how much reduce damage to receptors is proposed. Additionally application cases are presented for the effectiveness of protection wall in the LPG filling station. The study shows that the protection wall can effectively reduce the death probabilities of receptors located behind the wall in cases of the jet fires and the vapor cloud explosions.

사소한 부주의로 인한 화재사고가 큰 재난을 부르기도 한다. 개개인의 의식 속에 닫혀진 방화문을 열고 화재예방과 안전을 위한 최소한의 규정인 소방기본법을 준수한다면 화재의 양상이 변하고 대형화된다. 하더라도 모두가 행복한 내일을 꿈꿀 수 있을 것이다.

This study analyzed the cause of car explosion that occurred in the riverside park. The car carrying a male driver and a female passenger was parked in the park and explosion occurred inside the car. After the explosion, the driver and the passenger got burned. When they went to the hospital by the 119 Rescue Service, they stated that the car was sprayed with thinner before they had a quarrel and the explosion occurred during their quarrel. However, after several days, they changed their statement. They said that gasoline in the plastic bottle was poured and ran into the cigarette lighter. They tried to pull the cigarette lighter but pushed it by mistake. Then explosion occurred. Because only the explosion by mistake could receive car insurance, whether the cause of explosion was intentional or not became an issue. The car exploded was carefully investigated and analyzed. The statement of the driver and passenger was analyzed in the aspect of fire science. As a result, it was demonstrated that this car explosion occurred by driver's intention.

There has been a report of fire and explosion accident in regenerated thermal oxidizer (RTO). This paper was to investigate accident causes of RTO in the resin re-treatment process. The experiments carried out physicochemical properties and thermal stability analyses by using flash point tester, flammable range apparatus, autoignition tester, GC/MSD and thermal screening unit. We inferred causes of fire and explosion from the regenerated thermal oxidizer to prevent an accident of its process.

Resorcinol is widely used as a wood, tire adhesives, and a raw material of synthetic dye. This material with white crystals at room temperature, the particulates in the air can form explosive mixtures. It is known to be an explosion hazard when exposed to heat in a confined space. The study was evaluated fire and explosion characteristics of the resorcinol through thermal analysis, thermal stability, dust explosion characteristics, and the minimum ignition energy. From this study, it can be used to provide a safety information in the using and handling process of the resorcinol.

Explosion limit and flash point are the major combustion properties used to determine the fire and explosion hazards of the flammable substances. In this study, in order to predict upper explosion limits (UEL) for acids and ketones, the upper flash point of these were measured under the VLE (vaporliquid equilibrium) state by using Setaflash closed cup tester (ASTM D3278). The UELs calculated by Antoine equation by using the experimental upper flash point are usually lower than the several reported UELs. From the given results, using the proposed experimental and predicted method, it is possible to research the upper explosion limits of the other flammable substances.
