Study on Feasibility of Elevator Use for Fire Evacuation in a High-rise Building--Is Use of Elevator in Evacuation Really Effective for General People?--
At a building fire, occupants should usually escape by stairs, but not by elevators. However, in fact in many past fires, not a few people used elevators for their evacuation. Also, it is expected that the number of people who have difficulty to use stairs in evacuation would become larger, since the proportion of aged people in the total population has been rapidly increasing recently and also accessibility of disabled people has been improved in Japan and also worldwide. To consider this situation, we made a simplified model to estimate evacuation time by elevators, and conducted some case studies in order to examine the feasibility and issues of elevator use for evacuation. As the result of case studies, if the elevator use group can be designated only for a small part of occupants such as disabled people, it would be effective to use elevator in evacuation for those people. However, for other general people, it would be better to use stairs for their evacuation in most cases as well as to let the evacuation of disabled people by elevator more effective.
