  • In this study, investigation and appraisal method for the scene of a fire according to electrical fire hazards of hair dryer which is usually used at living space are presented. Hair dryer is briefly composed of heating part, wind part and control part. Electrical fire hazards of hair dryer are insulation destruction of power cord, ignition by overheat of heating coil, scattering spark on inside dust, overheat of motor by fan shackle, ignition by carelessness of user, and so on. Fire cause by hair dryer can be perceived through investigation about half-disconnection of power cord, contact badness of power plug, verification of heating coil, fan and switch. These results are expected to be utilized effectively in a countermeasure to prevent an electrical fire by hair dryer.

  • Casualties due to toxic smoke products have been reported as major fire damage. There are various tests in order to evaluate toxic smoke from a fire at home and abroad, and KS F 2271 as a test of the gas hazard of building finish materials has been conducted in Korea. The current test of the gas hazard exposes rodent, laboratory rat, to smoke gases to evaluate combustion gas toxicity by measuring acting time of that. this study performed a test of the gas hazard for combustible polymer material, Urethane and rubber flooring, and determined gases with the FT-IR. Quantitative results compared with standard value defined in BS6853 and toxicity index (R) was calculated. Using relative comparison with animal test and the toxicity index, We tried a variety of toxicity evaluation by correlation analysis of two tests.

  • Fire is recognized as a significant hazard in a service life of a structure. Therefore there is a clear need to provide an improved understanding of the performance of material and structures in fire and to provide clear design guidance in order to progress safety design especially high rise building. It is the aim of this study to investigates and analyze the study on the development of evaluation methods for fire risk analysis of high-rise building.

  • Objectives: The aims of this study are to derive the characteristics of diesel exhaust gas emissions generated during vehicle checking in the garage of fire stations and of the related improvement plans for proper air quality management. Methods: The researcher measured changes in the air quality inside garages according to the operating conditions of the exhaust facility and before and after vehicle checking at three fire stations. Results: During the checking of fire engines, a large volume of hazardous substances exceeding management standards were generated, and improvement of the discharge facilities was required for proper air quality management. Conclusions: It is necessary to study the hazard evaluation of firefighters' exposure to exhaust gas, to operate exhaust gas ventilation facilities, and to prepare technical standards for proper indoor air quality management.

  • In the area of disaster management, we have more focused on the rapid response and recovery, but preventive approach for disaster is becoming more and more important. For mitigation of disasters, we need to analyze the vulnerable area according to each disaster, and need to manage those area systematically. In this research, we selected the fire as a type of disaster, developed guideline of construction of vulnerability map of fire, and built the vulnerability map of fire in Changshin-Dong, Jongro-Gu, Seoul as a case study area. The vulnerability map of fire can be applied to grasp the vulnerable area in advance and manage it systematically. In addition, it can also be applied in the landuse planning and the rearrangement of infrastructure for the mitigation of disaster when we build detail city planning.

  • The objective of the present study is to predict the characteristics of the fire and smoke propagations in a clean room. Numerical calculations have been performed by using the finite volume method to obtain temperature and velocity distributions in the clean room. In odor to account for the turbulent flow characteristics, the standard $k-{\varepsilon}$ model is used. From this study, it was found that the fire propagation could be fully developed only after 150 seconds when the ventilation system in the clean room was off. And the smoke mass fraction showed a similar distribution as the gas temperature. Since the simulated fire was proceeded up to $20{\sim}30%$ of the room within 60 seconds. it could be recommended that the occupants should be evacuated from the room within 30 seconds.

  • It was conceived from the realization that there was a lack of studies on the fire risk compared to utility and importance of plastic which is widely used. In this study, the fire hazard of five types of plastic products was measured by Cone Calorimeter (ISO 5660-1). As a result, the time to ignition (TTI) of polyvinyl Chloride (PVC) plate delayed TTI (196 s), and polystyrene (PS) plate had the shortest TTI of 19 s. The total heat release (THR) of PS plate was measured at 213.07 % higher than the lowest measured PVC plate. Also, the PS plate will have 1.45 to 4.21 times higher $CO_2$ than other plastics, resulting in the highest incomplete combustion and the greatest possible damage of life. Thus, assessing the risk of fire revealed that PS plate is the most dangerous and PVC is the safest.
