As urban structures getting complex nowadays, the buildings become much higher. And use of underground increased. It led complex and various spatial structure. But there are lately incurred fire and explosion in building. As this disaster happens, the complex space cause serious casuality, because the occupants can not egress efficiently. Therefore, if the building is in fire, it has to be equipped with facilities and system for the efficient evacuation. Now although people have highly interested in facility evacuation which enhance evacuation efficiency in emergency situation, leading luminary evacuation light sources is only installed and developed through the nation. So, currently many kind of evacuation sign is developed. But it didn't practice the performance evaluation through real test. In this research, we analysed effects of the newly developed LED-evacuation-sign through in full scale test and were able to compare and evaluate egress behaviors by adjusting fire condition and normal times. Proceeding from this fact, in the open space which has several openings, The application of egress equipment such as LED-evacuation-sign which has high efficiency is also needed as well as the existing emergency Exit Light. The additional installation of LED-evacuation-sign reduced the evacuation time by approximately 60% and was analyzed to appear to be effective in case of fork of a path. With this result, we hope to provide basis data for LED-evacuation-sign’s efficient establishment in industry spaces, in case of an emergency |
