Människors gånghastighet i rök: Förslag tillrepresentation vid brandteknisk projektering

There is limited information about the behavior and movement of people in case of fire evacuation in smoke-filled environments, and there is limited guidance on how peoples’ walking speed in smoke can and should be represented in the fire safety design process. In this report, a literature review within this area, and a subsequent recommendation on how to represent walking speed in both smoke-free and smoke-filled environments is presented. The recommendation includes three different methods to represent the peoples’ walking speed in a life safety verification, depending on how the treatment of uncertainties is done on an overall level within the analysis. Finally, in the end of the report, a direction for future research in order to reduce the current uncertainties is presented.
