  • Currently, the number of a shopping center building is increasing because most people want to go a shopping center building easily for buying many things and eating some foods. That are a normal trend these days. However, the increasing number of shopping center buildings has been increasing the number of shopping center building fires which also have been making social problems. Therefore, this study was conducted for the fire department connection among other fire facilities because it is important for fire suppression. The research subject is on the fire department connections that are on 70 shopping center buildings of more than 5 years old constructed. Survey and analysis were conducted for 70 fire department connections. The result of this study is that all installed fire department connections have a type that includes one or two holes each at 65mm wide, and the average distance between fire department connections and access roads is 4.85m. The total average percentage of insufficiency conditions such as drive ways for fire trucks, visibility, accessibility, pressure range sign, installed height, cover of the hole, etc. is 45.3%. So improvement of law and systems, that are fire facility construction and maintenance implementations, will be needed in my opinion.

  • The definition of an apartment is a building more than 5 stories high and which is the standard law. Currently, the number of apartments is increasing much faster than detached houses. Owning an apartment is a normal trend these days. However, the increasing number of apartments has been increasing the number of apartment fires which also has been making social problems. Therefore, this study was conducted for the fire extinguisher among other fire facilities because it is important for initial fire suppression. The research subject is on the fire extinguisher that is in the underground parking lot of 40 apartment complexes which are more than 10 stories. Survey and analysis were conducted for 80 fire extinguishers. There are two fire extinguishers for each apartment. The result of this study is that all installed fire extinguishers are ABC dry chemical type, 92% of them is 3.3kg and that meet the legal height(less than 1.5m). However, the condition such as appearance, inspection, manufactured year, appearance of signs, material of signs, size of signs, etc. was insufficiency.

  • Emergency lights and exit signs are an indispensable part of safety precautions for effective evacuation in case of emergency in public buildings. These emergency sign indicates safe escape routes and emergency doors, using an internationally recognizable sign. However visibility of those signs drops drastically in case of emergency situations like fire smoke, etc. and loss of visibility causes serious problems for safety evacuation. This paper propose a novel emergency light and exit sign built-in with Bluetooth Low Energy (BLE) Beacon to assist the emergency self-guiding evacuation using devices for crisis and emergency management to avoid panic condition inside the buildings. In this approach, the emergency light and exit sign with the BLE beacons deployed in the indoor environments and the smart devices detect their indoor positions, direction to move, and next exit sign position from beacon messages and interact with map server in the Internet / Intranet over the available LTE and/or Wi-Fi network connectivity. The map server generate an optimal emergency exit path according to the nearest emergency exit based on a novel graph generation method for less route computation for each smart device. All emergency exit path data interfaces among three system components, the emergency exit signs, map server, and smart devices, have been defined for modular implementation of our emergency evacuation system. The proposed exit sign experimental system has been deployed and evaluated in real-time building environment thoroughly and gives a good evidence that the modular design of the proposed exit sign system and a novel approach to compute emergency exit path route based on the BLE beacon message, map server, and smart devices is competitive and viable.

  • Among the firefighting facilities, the fire department connection during firefighting is more important than any other facilities at the firefighting site to supply fire water. This study examined the water supply port of a fire department connection installed at an apartment building based on the Standard for Fire Safety (NFSC 502). The time of discovery was measured by fire fighters who knew or did not know of the water supply port installed in the apartment building, and by separating day and night. To maximize the use of the fire department connection which is the full fire extinguisher facility used by the fire brigade based on the results of the experiment, the author suggests improvement proposals that can clarify the installation location and install the location sign of the fire department connection for the Standard for Fire Safety (NFSC 502).

  • Evacuation fire doors were manufactured by applying phosphorescent paint to the whole fire door whose performance was already recognized, and applying heat sensitive paint around the grip. The facility was improved by the evacuation and safety functions on the fire door, which has been used as only a fire facility, and the fire door is also used as an evacuation facility. The brilliance of the evacuation safety fire door manufactured in this study passed the brilliance test of Korea Fire Institute with a performance more than the brilliance (7mcd after 60 minutes) of the existing inducement sign. During a fire, the visible area is larger than the evacuation door inducement, etc. and light preventive status in the lower part of the fire door was observed during the descent of smoke. Therefore, it is considered to extend the evacuation effective time of evacuators. In heat sensitive paint applied around the grip, a color change is observed on the fire door when approaching a certain temperature ($70^{\circ}C$). Therefore, the first disaster that evacuators can encounter on the grip of a fire door during a fire can be prevented and should be helpful in recognizing the backfiring possibility and preventing safety accidents for firefighters who must enter a fire space.
