With the development of the national industry, the importance of the elderly and children such as the elderly, disabled, and children is recognized. Similarly, the number of facilities for the elderly and children is increasing. Fires at facilities for the elderly and children cause heavy casualties. In response to these events, it is essential to activate fire alarms promptly and accurately and to secure evacuation routes. In this study, the laws and statistics related to facilities for elderly and children were reviewed, and problems with legal terms-such as elderly, children, others, unwanted alarm of fire alarm systems, blind spots of fire compartment standards, securing evacuation routes, and absence of standards for life safety rescue organizations-were identified. As an improvement measure, the legal definitions of similar terms-such as elderly, children, unwanted alarm checklist, and establishment of standards for fire prevention compartment-and introduction of other terms-evacuation elevators, the establishment of standards for life-safety rescue organizations, and provision of flame retardation objects for evacuees-were proposed.

The traffic accident of Fire engine takes place very much, compared with that of the past. The reason is that there is a lot of the increase of the demand in the fire, rescue, first aid, and the public request. Also, because the Fire engine should go out at the place of the accident very quickly, it should inevitably violate the traffic regulations. Therefore, this is due to the traffic accident. Despite the urgent situation in the infringement motive of traffic regulations, the outbreak of the traffic accident does not vary largely from the degree of the disadvantage. Accordingly, a fire officer should take charge of his social and economic disadvantage by himself. In this situation, a fire officer has no choice but to start moving passively not to be afflicted with his own disadvantage. Most of the situations concerning the fire fighting are the ones to be controlled urgently. Nevertheless, because of the disadvantage of the traffic accident, passive mobilization of the fire fighting equipment is the heavy burden of all the people of the nation. Therefore, Special institutional safety device should be ready for the protection of the life and property of all people. The special law concerning the processing in the accident of the emergency car needs to be revised. By establishing this special law, the government should not provide the officer who drives the fire engine with the disadvantage caused by traffic accident.

At present, the elderly population in Korea is 14% of the total population and then We has entered an the society of advanced age. Along with this, elderly people with dementia and palsy are also increasing. The demand for elderly nursing homes for elderly people with severe diseases such as dementia and stroke is also increasing, and the existing buildings are being secured by Conversion of existing buildings. However, it is difficult to evacuate and fire due to the out of date of buildings by Conversion of existing buildings. For example, there is a fire in the Indukukwon, Pohang City and Hyosung Geriatric Hospital, Jangseong in Korea, which have changed the use of existing buildings. Many elderly people died in a night fire. It was because of the sandwich panel walls and PVC flooring material produced toxic gas instantly. In this study, we investigated the nursing home that changing the use and established fire prevention of human injury and countermeasure of evacuation. First, the sandwich panels which leading to deaths due to the toxic gas were installed in most nursing home. We recommend the RC, the masonry wall, and the glass fiber panel instead of the sandwich panels, In addition, the PVC flooring is most used in nursing home, the flooring material is considered such as the building stones, the tile, and the yellow soil closing instead of the PVC flooring. Second, we investigated the installation status of fire fighting equipment. As a result, the automatic-emergency open&shut equipment, the smoke ventilator and the evacuation slide were rarely installed. In order to secure the golden time in case of fire and to prevent the asphyxia caused by the toxic gas, the law should be amended to install the equipment.

Positive displacement pumps with high pressure and water capacity are used large fires in various high-rise buildings. This study provides information for a performance approval standard of fire pumps for fire trucks based on centrifugal pump standards enacted in 2012. An experiment was conducted with a positive displacement pump for three levels of performance from the approval standard (V-1, 2, and 3). The efficiency of the pump was included in the reference, which requires the approval of 65% performance, the same as a centrifugal pump. The water pressure is between 1.5 and 2.5 MPa, and the required flow rate was established as at least $0.31m^3/min$ and up to $3.0m^3/min$. A relief valve was added to adjust the shut-off pressure due to the structural characteristics of the positive displacement pump. A strainer was also installed to prevent damage to the inside of the pump due to foreign matter. However, the strainer includes a difference from the positive displacement pump to operate without a vacuum pump and the centrifugal pump. This is due to the additional approval standard portion of the positive displacement pump, which is expected to be selected for more variety of fire-fighting equipment and proactive responses to fire suppression in a high-rise buildings and large fires. In conclusion, this approval standard was enacted in January 2016.

The concept of disaster management of cultural heritage is not clearly established and the range and type of it is not organized yet. Also, there is an ever-present danger in the field control because there is no system that can provide safety of cultural heritage from various dangerous factors. Concretely, institutionally, the regulation of disaster management of cultural heritage remains limited and there are not enough reasonableness in installation and management of fire-fighting equipment and safety equipment. Also, we need to take an action to secure the safety of cultural heritage from its surroundings. In this research, we setup the concept, type and criteria for disaster management of cultural heritage to overcome limitations and problems of management of cultural heritage. In addition, in order to raise the level of disaster management of cultural heritage, this research proposes direction to reinforce the disaster management of cultural heritage by investigating and analyzing consciousness of security guards and fire-fighting officers.

This study suggests a solution regarding the effects of apartment facility maintenance and fire safety facility maintenance on the residential satisfaction of residents. The results are as follows. Firstly, facility maintenance had a negative effect on residential satisfaction. Analysis revealed that residential satisfaction decreased the more breakdowns there were in the facilities. This revealed that when maintenance staff neglect the residents' complaints due to the repetitive aspect of their jobs, there was a negative effect on residential satisfaction; therefore, residential satisfaction must be increased by maintaining the facilities well and training support for maintenance staff. Secondly, fire safety facilities had a negative effect on residential satisfaction. Analysis revealed that residential satisfaction decreased the more malfunctions there were in the fire safety facilities and the more replacements there were in fire fighting equipment. This revealed the importance of safety and the fact that the apartment heavily relies on fire safety facilities because there may be a low awareness regarding safety; therefore, maintenance staff must lower the damage from fire safety facilities and to increase the residential satisafaction of residents. Lastly, there needs to be repetitive training and education for residents regarding fire fighting and evacuating in accordance with the fire fighting plan as a means to strengthen residents' safety awareness.

The power of semiconductor, Korea is continuously constructing semiconductor production line for keeping a front-runner status. however, studies and data about potential risks in semiconductor factory are still short. If fire does not initially suppressed, the fire causes a great damage. To decrease fire risk factors, in addition to fire fighting safety equipment, more important thing is how to design and construct fire protection system. The current fire protection codes about semiconductor factory come under functional law, and this law is short of consideration about particularity of factory. The existing prescriptive fire codes depending on experience compose without evident engineering verifications, thus equipments which is created by the current prescriptive fire code may bring about a variety of problems. For example, the design under the current regulation can not cope with the excessive investments, low efficiencies, and the diversifying construction designs and be applied to the quick changes of new technologies. Ergo, an optimal design for fire protection is to equip fire protection arrangements with condition and environment of production field. Manufacturing factory of semiconductors is a windowless airtight space. And for cleanliness, there exists strong flow of cooperation. Therefore, there is a need for fire safety design that meets the characteristic of a clean room. Accordingly, we are to derive smoke flow according to cooperation process within a clean room and construction plan of an optimal sensor system. In this study, in order to confirm the performance of proposed smoke-exhaust equipment and suggest efficient smoke exhaust device when there is a fire of 1MW of methane in the clean room of company H, we have implemented fire simulation using fluid dynamics computation.
