This thesis is based on the study of necessity of an addressable emergency broadcasting system to improve evacuation performance in order to minimize human casualty by avoiding the initial evacuation after fires such as the multi-unit dwelling fire in Euijeongbu in 2015. To minimize the damage from fire generated in a complex internal structure such as modern buildings, introduction of adaptable emergency broadcasting system, could increase the efficiency of evacuation by preventing of initial mistaken evacuation directions by alerting the accurate location of fire to the occupants, is needed. As such, this study designed and fabricated the addressable emergency broadcasting system using the existing addressable system. Its performance was compared with a conventional emergency broadcasting system to confirm the necessity of the addressable emergency broadcasting system to improve evacuation performance. The test result showed that the addressable emergency broadcasting system decreased the evacuation time by up to 30.3% in a small-scale model evacuation performance experiment, up to 54.6% in a hallway evacuation performance experiment compared to the conventional emergency broadcasting system.

Sprinkler system is the most effective fire suppression with high confidence among active fire extinguishing systems. According to the installation of the related system on buildings, more separation area of fire protection can be considered to the fire protection design, and also lower differential pressure (12.5 Pascal) is permitted on lobby of fire escape stairs and emergency elevator (25 Pascal shall be considered for none sprinkler system) with economic factor. More details will be handled on the related studies.

Purpose: This study propose efficient and practical measures to comply with the duty to secure safety and health of the Serious Accidents Punishment Act at small businesses. Method: Based on literature review and previous studies, a plan to comply with the Serious Accidents Punishment Act was reviewed by the link with the safety and health management system and using the process approach method, etc. Result: It was confirmed that if the safety and health management system is faithfully implemented, it is possible to comply with the duty to secure safety and health under the Serious Accidents Punishment Act. In addition, a methodology for fulfilling and inspecting the duty to secure safety and health was presented. Conclusion: If the safety and health management system is operated actively by utilizing the process approach and implementation inspection checklist, it is judged that it will be possible to comply with the Serious Accidents Punishment Act as well as to continuously improve the safety and health management system.

One of the notable changes in Korean Industry in 1990's was globalization. Many of Korea plants have been built In the foreign countries and many of foreign plants have been build in Korea. And it is believed that many foreign insurance companies will begin their business in Korea soon, as Korea will open their insurance market to them. While sprinkler system plays very important role in total fire protection system, Korean sprinkler system design has not been studied in depth. Thus, it is not easy to convince the performance of Korean sprinkler system and compare it to NFPA 13, Standard for the Installation of Sprinkler System. Design guideline from both system will be listed and compared in detail. Fire water demand from both system will be reviewed to evaluate its adequacy. Water spray density and actuation time will be estimated, too.

In this research, configulation of outside sprinkler system the prevention and postponement of vertical diffusion of blaze was studied prior to this study, vertical diffusion protecting sprinkler head has been developed and the sprinkler system was applied with discharge pressure of 0.05 MPa and flow of 60 l/min witch is stated in NFPA13's Exposure Protection Sprinkler Systems. Through the system design, we applied the system to the sample building and we made pertinent system to work manually and automatically linked to a fire alarm system. Also, we conducted a real-size mock up test verify the cooling effect of the outer wall and the postponement effect of the flame.

The technique detects radiant energy form a flaming fire of fuels contained carbonaceous material can be applied to fast growing fires. This technique applied detectors are ultimately effective when early detecting fire alarm system is required or the smoke and heat detectors can not applied. In Korea Fire regulation, a flame detector should be install in case that the installation height is higher than 20[m], chemical plant, hangar refinery. Therefore it is really necessary that a flame detector has to be developed as soon as possible. With foundation technique of flame detector, ideal sensing element and stable circuit design, a trial UV flame detector is manufactured. The stable and reliable technique of flame detector is established through the repeateed perfomance test and modification. An early detecting fire alarm device is developed through the modification, supplement of the structure and circuit. Results of the R & D for the manufacture of an excellent flame detecting device is carried out with the establishment of technique for the mass production and the qualified manufacturing process.

Thispaper presents the results of an experimental investigation into the fire performances ofsimply supported iTECH composite beams using an ISO834 standard fire. There are very few independent studies on the fire resistance of composite steel and concrete structures of various designs. The iTECH composite beam system has been used in construction, but nothing is known about its influence in a fire. To evaluate the fire resistance performanceof the iTECH beam, a test was conducted for 4.7m-span-length iTECH beams under given conditions in a laboratory. The fire resistance performance of unprotected coatings of the iTECH beam has been examined, and a longer period of fire resistance was achieved by increasing the beam coating's section size and decreasing its load ratio. Coatings for the fire protection of iTECH beams reduce the rate of temperature rise of the beam in case of fire, and the required thickness of spray-on fire protection coatings can be determined by means of tests.
