In the condition of changes in visibility by indoor ordinary lights, males and females ascent speeds showed a steady trend after the first decrease. In the condition of changes in visibility by smoke, males and females ascent speeds showed no obvious changes with the ascending floors. Participates were likely to use the handrail throughout the upward movement. In Condition1 and Condition 2, participants used the handrail in upward movement process as physical exertion. In Condition 3 and Condition 4, participants used handrail to identify the direction of movement.. s were likely more affected by the visibility of the stairs than males, and males ability to adapt to the environment were superior to females.
