The purpose of this study is to examine the walking characteristics of disabled people passing through fire equipment. The objective equipment of this experiment are a fire door and a "sheet shutter". The "sheet shutter" is a curtain-type silica-based screen that prevents fire from spreading. It has been recently developed as fire-protection construction in building. The objects' movements are recorded by VCR and motion capture system which can measure the 3-D coordinates of body parts. The walking speed and the movement of subjects are analyzed. Responses to a questionnaire which deals with degrees of difficulty for people vulnerable to disasters to properly manipulate the door are also examined. The results are as follows; 1. Physical ability and body size are related to the speed of the action of passing through the door. Small subjects, such as children and women, can easily get through the opening of a sheet shutter. 2. The force needed to open the sheet shutter door is less than for the fire door. 3. The movement of the upper-part of the sheet shutter door is different from the lower-part because the door has no rigidity. 4. It is more effective to widen the sheet shutter door than to raise it for wheelchair users'.
