Abstract |
According to NFTC 303 and NFPC 303, exit sign lights are set to be installed at a height of 1.5 m or more from the floor, which is a
common installation location for exit lights in Korea. However, there are cases where fire or electrical engineers arbitrarily interpret this and
install emergency lights in unique locations. Such uneven attachment positions of exit guidance lights can cause confusion in the cognitive
process of evacuees. Therefore, in this study, an installation location that can minimize the reaction time for recognizing evacuation route
guidance was derived. According to the experimental results, people's reaction time was the shortest by about 20% compared to other cases
when the evacuation exit guidance light was installed at the center of the emergency exit and at the location where the lower part of the
guidance light and the upper part of the emergency exit face each other. The results of this study can be used as an engineering basis for
evacuation guidance installation standards and cognitive performance evaluation. |
