Purpose: Currently, in the case of domestic fire fighting facility design, it is difficult to secure highquality manpower due to low design costs and overheated competition between companies, so there is a limit to improving the fire safety performance of buildings. Accordingly, AI-based firefighting design solutions were studied to solve these problems and secure leading fire engineering technologies. Method: Through AutoCAD, which is widely used in existing fire fighting design, the procedures required for basic design and implementation design were processed, and AI technology was utilized through the YOLO v4 object recognition deep learning model. Result: Through the design process for fire fighting facilities, the facility was determined and the drawing design automation was carried out. In addition, by learning images of doors and pillars, artificial intelligence recognized the part and implemented the function of selecting boundary areas and installing piping and fire fighting facilities. Conclusion: Based on artificial intelligence technology, it was confirmed that human and material resources could be reduced when creating basic and implementation design drawings for building fire protection facilities, and technology was secured in artificial intelligence-based fire fighting design through prior technology development.

Everybody may be vulnerable to fires depending on the time, place, and circumstances. Fire statistics show that the occurrence of fire death depends not only on the severity of a fire itself, but also largely on the conditions of occupants such as physical functions, the environment around occupants, and the type of facility where are fire occurs. The review of fire safety from the viewpoint of vulnerable populations does not simply mean additional special attention and care only to high risk groups, but instead it means significant review of fire safety design and systems for all people from a more universal standpoint. Therefore, in order to examine the strategies of a fire death-reduction program, safety measures suitable for the relevant high-risk groups considering the type of vulnerable person, the type of fire, and the type of building in residential occupancies. Solutions will require strenuous multilateral effort and flexibility.

As the rapid and various changing of social aspects, the structures are getting bigger, higher and more complex. The importance of evacuation is on the rise as increased using frequency of multiplex sale facility and it's high population density. According to the result of a survey with 4 domestic wholesales mart's population density, the average and maximum was 0.41(人/$m^2$) and 0.46(人/$m^2$). considering evacuation dangerousness, the maximum value will be suitable for computation of evacuation capacity and this will be submitted as a basic data for computation of evacuation capacity.

Today, our city structure is being complicated from the development of industry. Invisible losses, life and fortune loss caused by arson is embossed in our society. The preparation of counter plan about increasing factors of fire damage is not easy. With respect to mankind life, however, it is very important. Therefore, the focus of this research examine refuge degree in each smoke density level when a fire break out in the space. I evaluated auditory guide facility thorough real scale test. In this thesis, I will propose the efficient refuge deriving facilities.

This study is to establish the appliance model for the automatic fire alarm system in clean room within the framework of the performance based design. Because of the environmental and dimensional characters of clean room, this space is exposed to fire and toxic damage, so it is very important to notify the occupants of these dangerous situations.

Incase of not considered seismic design at transformer vault which is made of many informant electrical facility, facility is damaged, electrical fire breaks out and second damage is able to break out at generating earthquake. But seismic design yet is not applied to at transformer vault in the country. Regard to seismic design method of electrical facility installed in the building internal, we present the seismic design of electrical facility using "Building construction design standard" in internal and "Manual of seismic design and construction for Building Electrical facility" in japan. This paper will be used detail seismic design of pipe and facility. reliability inspection plan for seismic design and construction of electrical facility

In the case of residential facilities, general fire scenarios cannot be applied. Becauseit is difficult to quantify due to the types of combustibles and various fire loads. Existing research conducting surveys of combustibles, but research on fire characteristics is insufficient. Therefore, in this study, an Excel macro that can be quantified by experimenting with the HRR experiments of sofa, drawer, mattress, chair, desk and TV, which are typical combustibles. As a result of experimenting 6 loading combustibles in domestic residential facilities by using a furniture calorimeter, values of 2,391.26kW appeared from the sofa, 1,891.80kW from the drawer, 1,778.95kW from the mattress, 1,104kW from the chair, 291kW from the desk, and 135.09kW from the TV. Also, by applying the α value of the fire growth rate by classifying fire-growing speeds at NFPA 72 (National Fire Alarm Code 2007, Annex B), the mattress can be defined as Very Fast, the sofa and drawer Fast, the TV Slow, the desk Slow, and the chair Medium.

HFC-227ea and HCFC Blend A were evaluated using full-scale fire tests to obtain information on their fire suppression performance, drop-in capability, thermal decomposition products and physical behaviour of the agent such as its flow characteristics in the piping system. Also, full-scale tests were conducted with Halon 1301 to provide a basis for comparison. Halon 1301, at concentrations of 5% to 7.5%, showed effective total-flooding fire- extinguishing performance for all test scenarios. HFC-227ea, at a design concentration of 7.6% or higher, and HCFC Blend A, at a design concentration of 12%, extinguished all fires in the test facility, however, these agents produced higher concentrations of acid gases than Halon 1301. The quantity of the acid gases generated during fire suppression was dependent on agent concentration, agent discharge time, fire type and size as well as extinguishment time.

In Korea, fire is the second frequent disaster. A total of 32,966 fires were happened in 2002, and injured 2,235 people and damaged 12 million dollars. So, we developed several components related to fire in order to decrease these victims and the amount of damage and have applied those components to Daegu Fire Agency. In this paper, we describe the developing system. It consists of 5 major components: mobile fire facility management component, web service component, fire management component, fire server, and fire application. They were developed in object-oriented computing environment, ATL/COM and Visual C++. So, they have some advantages such as high reusability, full interoperability, and easy understanding.
