  • The purpose of this study is to measure the change in evacuation time at high schools according to the change in hallway width using an evacuation simulation program and to analyze the result of such change. In order to measure the evacuation time according to the change in the hallway width according to the 「Rules on the Standards for Evacuation and Fire Protection Structures of Buildings」 and to analyze the change in evacuation time resulted from the increase in the number of occupants, a scenario was constructed by applying the 「performance-oriented design method and standard for firefighting facilities, etc.」. As a result of the experiment, it was found that the evacuation time was the shortest when the width of the hallway was the widest, which was 3m. On the other hand, the evacuation time took the longest at 1.8m, which was the width of the second narrowest hallway. For the safety of high school students who spend a lot of time at school, it is necessary to secure a wide hallway width when building a new school or to provide periodic safety education in the case of an existing school whose hallways are considered narrow.

  • Because of the increasing demand for day care centers, The Korean government has enforced childcare accreditation. The government has created the evaluation certification system for child care facilities. But the system includes variable items, and the physical rules are not sufficient for ensuring security and quality amenities. So this study, through literature search, examined the rules of Child Care Centers in the U.S. and compared them with those in Korea focusing on the provision of security and amenities. The standards found in 4 U.S. states were investigated, and the results are as follows. The rule pertaining to the size of indoor activity spaces in C.C.C. allows the spaces to be smaller in Korea than in the U.S. There is no specific criterion for infants and toddlers in our standard. When comparing the standards of Korea with those of the United States, Korea's standards do not state specific rules about child care facilities such as indoor furniture, finishes and space planning. Additionally, the binding force ensuring compliance with the standards of physical facilities is weak. Thus, the ratings of child care standards for the physical environment should be presented in detail. And if a center does not comply with the criteria, stronger penalties will have to be imposed.

  • Sludge incineration facilities are socially recognized as a hate facility. Therefore, a careful deodorization plan must be established. Therefore, the incineration facility must conduct research on odor ventilation. In this study, a odor diffusion simulation in an incineration facility was conducted and analyzed. In particular, research was carried out on carry-in rooms, pre-treatment rooms, and storage facilities for crops, which are expected to rapidly spread odor. As a result, ammonia 1.62, hydrogen sulfide 0.63, and acetaldehyde 0.73 were found in the transfer room. In addition, pretreatment rooms and stencil storage facilities were found to be lower than regulatory standards.

  • Fire prevention strategies should be aimed at the prevention of structured fire since average annual rates of structured fire have been increased due to economic growth resulted in increasing high rise buildings and multipurpose occupancies over the past ten years. Hence, this study mainly focused on the improve method and problems in the field test of fire detector in compliances with experimental consideration. And it leads us to the flowing conclusions : Firstly, it is necessary to formulate a safety standards on field test. Nowadays, the test enforced in many ways without formulated standard. Therefore it is necessary to be complete the arrangements standardized and how to do the test with formulated safety standards. Second, it is necessary to establish the regal guidance with regard to inspection equipment, ie density, component and temperature of test equipment should be considered. Also the equipment is need to be standardized and improved. Third, fire inspector's competency in their practice should be enhanced. The problems arising from the lack of knowledge and competence regarding inspection could be settled by providing professional education to ensure proficiency in their practice. Specialized training, as has been noted, should be offered in accordance with occupancy type, scale and fire protection system in the fire facilities.

  • In this study, we would evaluate fire risk by domestic standard for artificial turf installed on field and roofs. Today domestic regulation for artificial turf only applies to outdoor uses and especially KS M 3888-1 has compulsion but limited to school athletic facilities. Indoor regulation complying with National Emergency Management Agency (No. 2012-35) was enacted as recommendations. Thus this study did combustion test of artificial turf installed on field. Analyzed result by 45 degree flammability test, standard was inadequate to judge the fire risk so we compared and analysed its characteristic through combustion test of flame retardant finishing carpet used as flooring. Test and assessment result of its ignitionability by 45 degree flammability test showed that carpet was satisfied with flame retardant finishing performance standard contrary to artificial turf. For this reason, by conducting cone calorimeter test, the combustion property after ignition would be analyzed and evaluated and then this study will suggest a countermeasure for strengthening standard.
