A fire resistance certification needs to be obtained before fire protection paint can be used in Korea. In the case of paint, the tests for certification are fire, gas hazard and bond strength. According to the hazard test standard of combustion gas, 16 mice are sacrificed every test. Therefore, there are ethical problems for the experimenter and legal problems for the laboratory. Accordingly, many alternatives are being assessed, such as combustion gas analysis, but they have not replaced animal testing yet. With gas hazard testing, the exhaust gas temperature can be measured. The property of the initial reaction of a specific fire paint can be characterized by this temperature. The purpose of this study was to consider the improvement point for a gas hazard test through comparative analysis of the exhaust temperature and the time of death of the mice.

Because of development of printing technology, toner cartridge particle becomes smaller and more dangerous. And sometimes we had incidents with dust explosion of toner cartridge particle at recycling facilities in Japan. Therefore we studied on hazard of toner particle relating with dust explosion. We found that toner particle is so dangerous compared with most organic solids, even though it does not belong to hazardous materials in the UN regulation and the Japanese Fire Service Law.

The leisure life pattern of people is changing to a familial and enthusiastic way that eventually develops the camping culture. Thus, the number of campers and the size of camping market have been dramatically increased due to significant expansion of camping people. However, many camp grounds and facilities are operating without a proper registration by government rules and regulations. In addition, many of electronic and gas equipment and tools are not used in a safe way and in a safety regulatory boundary. Therefore, campers at the camping ground is situated in a fire and safety hazard. In addition, there is limitation in rules and regulations associated with camping ground safety and fire. This study analyzed the fire and hazard guidelines and rules regulations of developed countries of campground and compared them to the current situation in South Korea. Therefore, this study is to develop a safety and fire hazard guidelines and rules and regulations related to camp ground operation, gas and electronic equipment operation and management. The study will eventually reduce the future fire and safety incidents in a campground in South Korea.

Many railway safety measures are carried out after Daegue subway fire accident. Such as replacement of train interior material, fire extinguish and toxic gas evacuation facilities, exercise on emergency response, setting up of national safety management system, and safety technology research. But these safety measures are not considered by system safety due to lack of risk and hazard information. In order to assess fire risk on system level, we proposed hazard events and causes classification for railway fire accident risk analysis.

The fire protection regulation for the nuclear power plants is based on the qualitative fire hazard assessment and the quantitative fire risk analysis, and the fire risk is managed by the fire protection plan with the appropriate balance among the fire prevention, fire suppression and the minimization of the fire effect. In these days, the zone model or the field model is generally used for the detail evaluation for the fire risk. At this paper, with consideration of the present trend, we evaluate whether the quantitative fire risk analysis and the assessment of fire result for fire areas at nuclear power plants can be possible by use of Fire Dynamics Simulator (FDS) that is the state-of-the-art fire modeling tool. Consequently, it is expected that the quantitative fire risk evaluation propelled by the fire modeling can be available as an applicable tool to improve the core damage frequency as well as the quantitative fire risk analysis.

Recently, the fire by sheath heater has been occurred frequently on winter season. The sheath heater has simple internal structure and boils water simply. Therefore, the use of sheath heater has been increased. In this study, found the fire hazard property of sheath heater from understanding the fire mechanism through the experiment to get the measure for decreasing the occurrence of fire. For the analysis of the fire hazard property of the sheath heater, performed the test of temperature change and ignition temperature by using current product. On the result of test, the sheath heaters are the most dangerous appliance to arise fire. Water temperature controller attached to sheath heater is not sufficient to prevent overheating it. The sheath heater should have level switch of water and temperature controller for heater itself to shut off the power supply. Because the cause of fire by sheath heater is overheating itself in the situation of lack water.

This study presents on the analysis fire hazards of drum type electric washing machine. In order to analyze fire hazards fire experiment is conducted. The fire experiment is conducted to simulate under the normal condition and abnormal condition. The experiment under the abnormal condition is simulated in safety device failure, situation of accumulated dust and tracking phenomenon caused by humidity. The results show that fire hazard is high at the abnormal condition. In this paper, we suggest to use the safety device of low operating temperature in electric washing machine for reducing fire hazard.

In this paper shows the development of the Program(FDS2EXODUS) for Generating Hazard condition file of BuildingEXODUS code based on the FDS Fire-simulation Data. The program were applied with numerical method to translate from FDS to BuildingEXODUS. Using both single or multi block meshes of FDS get to be possible. For application of fire effect, the fire data were loaded directly to BuildingEXODUS in the case of FDS code with using this Program(FDS2EXODUS). It was very convenient to input to BuildingEXODUS and could be reduced the procedure of egress simulation from fire disaster.

Hazard of Biodiesel (BDF) was studied. Biodiesel is a name for a variety of ester-based fuel made from vegetable oils. Recently importance of biodiesel is increasing, and its fires were sometimes reported. Therefore we studied on hazard of biodiesel comparing (petroleum) diesel oil and vegetable oil, raw materials of biodiesel. We found that biodiesel is auto-oxidized easily and ignites, and its flash point decreases when even small amount of methanol exists. And there are various raw materials to manufacture biodiesel, so we studied the difference of these materials, and their aging on safety.
