Process of Human Behavior in Fires.
(30/05/2013)
Evacuation models, including engineering hand calculations and computational tools, are used to calcuate the time it takes to evacuate a building, which can then be used in an engineering safety analysis. However, there is a lack of available data and theory on occupant behavior for use by evacuation models to estimate evacuation time results and their uncertainty. In lieu of data and theory, evacuation models (and users) make assumptions and simplifications about occupant behavior, which can inappropriately characterize the time it actually takes to evacuate a building. In cases where assumptions lead to evacuation estimates that are either too optimistic...

Evacuation models, including engineering hand calculations and computational tools, are used to calcuate the time it takes to evacuate a building, which can then be used in an engineering safety analysis. However, there is a lack of available data and theory on occupant behavior for use by evacuation models to estimate evacuation time results and their uncertainty. In lieu of data and theory, evacuation models (and users) make assumptions and simplifications about occupant behavior, which can inappropriately characterize the time it actually takes to evacuate a building. In cases where assumptions lead to evacuation estimates that are either too optimistic or too conservative, buildings and procedures can be designed with either insufficient or unnecessary (and costly) egress routes and fire protection/notification systems. A solution to this problem is to generate theory on human behavior during evacuations from building fires that can be incorporated into evacuation models. Once this theory is robust, validated and incorporated into evacuation models, these tools can begin to predict occupant evacuation behavior rather than reylying on the user to determine behavior before the simulation begins, as is now the case.
