This study shows the difference between groups with multivariate analysis of fire prevention activities, special investigations of fire safety, and fire safety management according to the management method of apartment houses and the inspection of firefighting facilities. The results of the analysis are as follows. First, there was a significant difference in fire prevention activities according to the quality of inspection of firefighting facilities. This means that fire prevention is high if the fire safety manager's ability to inspect firefighting facilities is excellent and the fire safety inspection is conducted in accordance with national fire safety standards and checklists. Second, there was a significant difference in the fire safety special investigation according to the management method of the apartment buildings. The manual operated by the management entity and the management entity's management and execution help the organization members to expedite work. This expedition of work creates a high possiblity to get a good evaluation from the special investigation of fire safety. Third, analysis of fire prevention activities showed a significant interaction between the inspection of firefighting facilities and the management method of apartment buildings. The analysis shows that that there is a positive correlation between the level of fire prevention and both the fire safety manager's ability to inspect firefighting facilities and the degree to which the inspection is conducted to meet national fire safety standards.

In order to establish an evaluation method that can quantitatively evaluate the fire safety of existing buildings in Korea, a stochastic approach is needed to consider the extent of damage in the event of actual fire, along with the operation and installation of facilities. Accordingly, as a basic study for the establishment of fire safety assessment methods for buildings, this study aims to analyze the results of safety inspection and the degree of damage caused by the operation of fire doors and fire shutters in order to derive the reliability of fire doors and fire shutters. As a result, the results of inspection of fire shutters and fire doors and the results of operation using fire statisticians are as follows. As a result of the inspection, the positive rate of fire doors was about 82% and 98% of normal operation was derived from the fire investigation.

In the past, the risk of fire and the rate of fire occurrence has increased gradually as the quality of life improved due to rapid economic growth, and the government enacted Fire Prevention Act. The existing inspection method was revised considering the rapid increase in the number of fire-fighting objects(hereinafter referred to as specific fire-fighting objects) that require the installation of fire-fighting facilities, and has been applied to this day. On the other hand, unlike the rapid increase in specific fire-fighting objects and the development of fire prevention technologies, the scope of work and inspections by unsuitable inspectors caused a large fire accident, which required improvement of the related laws. This study evaluated, the Act on the relationship of firefighting facilities, which had been implemented previously to identify fire victims, save lives, secure independence of fire inspection agencies, and ensure the accuracy of fire prevention actions.

In the course of increasing in human and material damage caused by fire, it is an important research field to develop clean extinguishing agent which does no harm to global environment as well as has a good extinguishing efficiency. This research is a basic step to develop a new clean extinguishing agent. In order to get a satisfactory result, we tested fire extinguishing ability using nitrogen and Novec mixtures gas which are inert gas and new clean extinguishing agent. We used Cup Burner Test made by international standard ISO-14520 regulations of gaseous extinguishing agent ability test, and the fuels used in the test are n-heptane, methanol, ethanol, iso-propanol and 1-butanol. The experimental results of flame extinguishing concentration are n-heptane 6.54%, methanol 8.47%, ethanol 6.98%, isopropanol 6.10% and butanol 6.54% by pure Novec agent. So the finding is that a new clean agent, Novec has an efficient extinguishing ability in a state of gas. Also, in a test as to mixtures gas of nitrogen and Novec, it has a good result for minimum oxygen concentration is under 16%.

In this study, results of completion inspection are investigated according to the performance of the firefighting construction supervision personnel and according to the necessity of clean air supply in a performance test of the firefighting construction supervision personnel. The results of the completion inspection are measured and the causes of defects in the fire protection facilities after issuance of a completion inspection certificate are analyzed. The findings of this investigation can be used to minimize the risk of apartment fires and improve the performance of firefighting construction supervision personnel. The results of this study are summarized as follows. First, the results of the completion inspection conducted by the firefighting construction supervision personnel varies according to particular occupation. The performance of fire facility supervisors from design companies and fire construction companies were significantly higher than the fire officers. Therefore, it is necessary to employ supervisors who have experience in supervising the construction of apartments, in order to improve the performance of fire construction supervision officers. Second, the analysis of the completion inspection results according to the necessity of a clean air supply for performance tests of firefighting construction supervision personnel showed that the necessity of a clean air supply was significantly higher for fire facility supervisors from design companies and fire construction companies than for the fire officers. In order to improve, the completion inspection should be carried out up until the completion date of the building. In addition, a system needs to be established to ensure that clients are not able to demand that a completion inspection certificate be issued on the construction completion date. Finally, it is found that defects of completion inspection after issuance of a completion inspection certificate affects the result of the completion inspection. The results of the completion inspections conducted by the fire facility supervisors from design companies and fire construction companies were affected significantly less by defects than that of the general contractors. Research shows that faults have occured in firefighting facilities after the issuance of a completion inspection certificate due to the client and the construction company demanding the issuance of the completion inspection certificate.

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".
