ABSTRACT

This study aimed to develop an evacuation sign to ensure people quickly find an exit in smoke and darkness in the early stage of fires, and to measure changes in brain waves in the four areas of the cerebrum (frontal, parietal, temporal and occipital lobes) when people effectively respond to evacuation within the golden time. The frequency of waves observed in the left and right frontal lobes showed that the frequency of delta, theta, alpha, beta and gamma waves when there was no evacuation sign was about 3.1%, 5.8%, 12.8%, 31.5% and 46.8% respectively. The frequency of delta, theta, alpha, beta and gamma waves when there was an evacuation sign was about 3.3%, 5.7%, 12.5%, 40.1% and 38.4% respectively, indicating that the frequency of beta waves increased by 8% and that the frequency of gamma waves decreased by 9%. The frequency of waves observed in the left and right parietal lobes showed that the frequency of delta, theta, alpha, beta and gamma waves when there was no evacuation sign was about 4.5%, 6.3%, 16.5%, 28.6% and 44.1%. The frequency of delta, theta, alpha, beta and gamma waves when there was an evacuation sign was about 4.5%, 6.1%, 15.6%, 41.9% and 32%, indicating that the frequency of beta waves increased by 14% and that the frequency of gamma waves decreased by 13%. The frequency of waves observed in the left and right temporal lobes showed that the frequency of delta, theta, alpha, beta and gamma waves when there was no evacuation sign was about 3.9%, 7.9%, 13.5%, 30.5% and 44.2%. The frequency of delta, theta, alpha, beta and gamma waves when there was an evacuation sign was about 3.5%, 8.9%, 12.9%, 37% and 38.1%, indicating that the frequency of beta waves increased by 7% and that the frequency of gamma waves decreased by 7%. The frequency of waves observed in the left and right occipital lobes showed that the frequency of delta, theta, alpha, beta and gamma waves when there was no evacuation sign was about 2.5%, 5.1%, 20.1%, 27.1% and 45.2%. The frequency of delta, theta, alpha, beta and gamma waves when there was an evacuation sign was about 2.1%, 5.6%, 19.1%, 41.6% and 31.6 %, indicating that the frequency of beta waves increased by 15% and that the frequency of gamma waves decreased by 14%.
