In this study, a fire and evacuation inside an electronic equipment room in environmental energy facilities were conducted and evaluated using a numerical analysis method. In the fire simulation, the visual distance, temperature distribution, and CO concentration distribution were analyzed using FDS. Based on the results, the Pathfinder program, which is an evacuation simulation, was used to calculate the evacuation time of the occupants and derive an evacuation safety evaluation. As a result, the Available safe Egress time (ASET) of P-01 and P-05 was 203.3 and 398.6 s, respectively. For the Required safety Egress time (RSET) results, all evacuees were evacuated at all points and the safety of the evacuee was secured this simulation showed that the safety evaluation is based on the non - operation of the fire - fighting equipment to improve the safety, making it possible to secure better evacuation safety performance owing to the fire of other fire - fighting facilities.

The purpose of this study is to investigate the preparation time of fire-fighting water for public fire hydrants and ground, underground fire hydrants. The equipment preparation time for stage 1 was 20.50 seconds for ground type and 24.67 seconds for underground type. The reason for this difference in preparation time is that an underground fire hydrant requires additional standpipes to connect to the main conduit of Paru and the underground hydrant, which open the manhole cover. Water tank Maintenance joint with water hose male coupling of the second stage was similar to that of the ground type of 48.50 seconds and underground water tipe of 49.00 seconds. This is because the operation of connecting the fire hose to the maintenance tank of the water tank car is the same. In the third stage, the water pipe connection was 43 seconds for ground type and 174.33 seconds for underground type. The reason why the time for connecting the water pipe to the fire hydrant is large difference is that the underground fire hydrant is opened by opening the manhole cover, After connecting the stand pipe to the fire hydrant, the additional process of connecting the water pipe to the stand pipe is required, which is considered to have greatly increased the time required. The opening of Water Control Valve and spindle Valve in the fourth stage was 66.50 seconds for the ground type and 78.83 seconds for the underground type. This difference is due to the fact that the spindle of the ground fire hydrant is located on the main body and can be easily opened, but the underground type is located next to the main body under the manhole and requires additional time to connect the opening equipment.

In the event of a fire and a disaster, prompt and accurate alarms inside and outside the building are directly related to the minimization of damage and the success of life evacuation. However, due to unwanted fire alarms in automated fire detection systems, the number of dispatches by misunderstanding in the 119 service is increasing. This causes the insensitivity to the safety of building managers and the waste of the fire-fighting power. Therefore, in this study, the statistical databases and literature on unwanted fire alarms in Korea and abroad (USA, UK) were identified and the management systems for unwanted fire alarms were compared and analyzed to identify problems of statistics in the management systems for unwanted fire alarms.

The purpose is to evaluate evacuation safety by simulating the toxic effects of hydrogen fluoride leaks in areas surrounding national industrial complexes and to suggest alternatives for areas that do not satisfy evacuation safety. For human casualties caused by hydrogen fluoride leakage accidents, Available Safe Egress Time (ASET) is calculated by the toxic effects quantified with the Areal Locations of Hazardous Atmospheres (ALOHA), an off-site consequence assessment program. The Required Safe Egress Time (RSET) is calculated through Pathfinder, an evacuation simulation program. Evacuation safety is assessed by comparing ASET and RSET. The ALOHA program was used to evaluate the time to reach AEGL-2 concentration in 12 scenarios. The Pathfinder program was used to assess the total evacuation time of the high school among specific fire-fighting objects. Of the 12 accident scenarios, ASET was larger than RSET in the worst-case scenarios 1 and 9. For the remaining 10 accident scenarios, the ASET is smaller than the RSET, so we found that evacuation safety is not guaranteed, and countermeasures are required. Since evacuation safety is not satisfactory, we proposed to set up an evacuation area equipped with positive pressure equipment and air respirators inside specific fire-fighting objects such as the high school.
