Recently, the necessity of rapid response to social problems such as disasters and quarantine arising from the complex and diverse social structures has emerged. As the number of large buildings increases, large-scale human damage is expected in the event of a disaster such as fire. To solve this problem, efficient control must be achieved through interfacing with various equipment and facilities installed inside the building. In this paper, we intend to study the interface method for various facilities in the building for efficient control. In detail, the facility standard model is defined by examining the status and specification of building. In addition, we intend to design and propose a standard facility communication data frame to support the protocol applicable to this model.

Wooden cultural heritage is vulnerable to fire, flooding and other hazards. Therefore, an effective disaster prevention and mitigation strategy for them should include preventive measures in a full range of management. These were used to construct a disaster safety system for 508 wooden cultural heritage items by the Cultural Heritage Administration. According to the type of ownership and administration, national and public heritage is controlled by personal management or commissional management. Among them, it is arranged with the safety security institute for important cultural properties. In addition, they have problems of field management with no computerization about the management information for a disaster facility system. Therefore, this study aimed to develop a DB platform that can share information with many users who need to manage cultural heritage. Through a field survey, it is feasible to develop a disaster facility system to provide the information, such as the main data, quantity and location.

Seonhwa Bongsa Goryeodogyeong written by Seogeung of Song nationality is the most vivid record of sailing in the West Sea of Goryeo. Seogeung who visited Goryeo on a ship sailed from Heuksando to Byeokrando using a fire signal of the islands area. Fire signal was installed in the Goryeo area, was located nearby the sea route at that time, and was marked by smoke during the day and torched at night so that the navigators could identify it 24 hours. In addition, it was installed at the top of the mountain so that the navigators could easily identify it from a distance. Goryeo fire signal is satisfied by qualification of modern aids to navigation and Visual range is checked about 29-39 miles, Luminous intensity of fire signal estimates to approximately 9,105-168,610cd. Therefore, the fire signal of Goryeo was very easy to use and was highly reliable as operated by the nation and its role in aiding navigations facility as an essential for safe navigation.

Under the present code, sprinkler heads operating simultaneously are fixed at 30 in number, irrelavant to building use. But, apartment buildings in korea have mostly wall-and-slab structure and every house hold is separated by fire-proof wall. Therefore, apropriate review about present system should be made for the safety assurance by reasonable effort.

Under the Act amended on August 4, 2011, a special fire-fighting investigation was conducted by the relevant person (owner, manager, oil refineries), and the responsibility was also given to the relevant person. Instead of directly entering all existing fire-fighting targets and investigating the maintenance and management status of fire-fighting facilities, the fire-fighting agency selects and visits some targets every year, checks the maintenance and management status of fire-fighting facilities, corrects them, and imposes fines, etc. Reasons for the introduction of the system were the establishment of a private autonomous correction system by strengthening the responsibility of officials, lack of firefighting professionals, possible corruption due to frequent public contact, and responsibility of fire agencies. However, many problems arose even after the introduction of a special fire investigation system. A special fire investigation, one of the fire safety systems, checks whether related public officials and especially fire officials are properly installed, maintained and managed in accordance with relevant laws. Special firefighting investigations were introduced as firefighting inspections at the time the firefighting law was enacted in 1958, and have undergone a revised process more than 30 times until recently. Firefighting Facility Installation, Maintenance and Safety Management Act", the existing firefighting inspection was changed to a special firefighting investigation and accepted. At the time of enactment of the Fire Service Act in 1958, a special firefighting investigation was introduced as a firefighting inspection, and until recently, more than 30 revisions have been made. In 2003, as the existing fire fighting system was divided into four laws, it was approved by changing the existing fire fighting inspection to a special fire fighting investigation in the "Fire Fighting Facility Installation, Maintenance and Safety Management Act".

The automatic fire detection system is an important facility installed with focusing on minimizing the damage from a fire. This paper presents in the followings as the methods to reduce the false alarm of the automatic fire detection system; first, to prepare for legal standard so that revised legal standard can be applied to the fire fighting property prior to revision; second, to introduce the performance based fire detection protection design in the law based fire protection design; third, to maintain the wiring of worn-out detector; forth, to introduce an evaluation system to the education for the fire warden; fifth, to extend the standard of MTBF(meantime between failure) of the detector; sixth, to extend of installing the analog type detector; seventh, to improve the structure of reset switch.

Fire model shall be verified and validated to reliably predict the consequences of fires within its limitations. This study aims to predict pool fire phenomena with two rooms using CFAST and to compare CFAST simulation results with PRISME experimental data which can be applicable to the fire of nuclear power plant facility. Five different mass loss rate(MLR) are used in the simulation and the simulated results of specific quantities such as temperature, chemical composition are compared to the experimental data. From this study, the CFAST simulation results with the proper MLR show better similarity and trend with pool fire experimental data.

The conventional fire detection devices are operated after a processed fire phase, which are sensing only a high density of somke level or high temperature heat. They are not so precision to detect a fire in the early phase to protect the facility form the fire. We need to develope a new high precision smoke detection system to keep expensive industrial facilities most reliably form fire. A new optical precision smoke detection system was developed. It monitors very low level density of smoke particles in the air. It is operated continously through many years without a stop or any malfunction. The developed precision smoke detection system will be installed in important industrial facilities, such as power plants, underground common tunnel, main control rooms, computer rooms etc.

The present study was numerically and experimentally performed to investigate the fire suppression performance of water mist spray subjected to thermal radiation in closed space. Downward-directed water mist sprays to interact with an under kerosine pool fire were investigated in test facility. The mass mean diameters of water mist droplet were measured by PMAS under various flow conditions. The developed water mist spray nozzle was satisfied to the criteria of NFPA 750, Class 1. The mechanism of the fire suppression by water mist was concluded to be cooling of the fire surface which lead to suppressed of fuel evaporation. It was proved that the water mist spray system under lower pressures could be applied to underground fire protection system.
