Fire risk-based evacuation safety derived from statistical analysis by type of building

Abstract

The authors and their colleagues have been trying to construct a framework method of risk-based fire evacuation safety design for buildings. In the framework, it is necessary to determine a benchmark fire risk level to select design fires and scenarios appropriately. An attempt was made to develop this benchmark fire risk level by using 10 years of statistical data on residential fires. First, the acceptable evacuation risk for fire was established assuming that the level of evacuation risk for dwelling houses is the benchmark. Secondly, the fire statistics for buildings with different types of use was analyzed to establish a formula for the acceptable evacuation risk in the context of performance-based evacuation safety design that commonly holds for various types of use. Finally, there are discussions of other methods for determining the bench mark evacuation risk. © 2011 INTERNATIONAL ASSOCIATION FOR FIRE SAFETY SCIENCE.
