Abstract
Queuing during evacuation is a phenomenon that has to be regarded when designing large buildings with high occupant loads. In theory it would be possible to eliminate or at least reduce the queuing time when evacuating a building if the building is designed with a large number of exits. The problem is that exits equal money and for that reason it has to be assumed that the building constructors’ aim is to keep the number of exits down. This will also be the aim for the fire safety consultant even though he or she also has to take the safety of the occupants into account. Because there are almost no directions about how long it is acceptable to let people queue in front of an exit, there is a risk that fire safety consultants overestimate... (More)
Queuing during evacuation is a phenomenon that has to be regarded when designing large buildings with high occupant loads. In theory it would be possible to eliminate or at least reduce the queuing time when evacuating a building if the building is designed with a large number of exits. The problem is that exits equal money and for that reason it has to be assumed that the building constructors’ aim is to keep the number of exits down. This will also be the aim for the fire safety consultant even though he or she also has to take the safety of the occupants into account. Because there are almost no directions about how long it is acceptable to let people queue in front of an exit, there is a risk that fire safety consultants overestimate the acceptable queuing time to fulfill the clients’ wishes and as a result of that jeopardizing the safety of the buildings’ occupants.

The aim of this study has partly been to investigate what there is to be found about acceptable queuing time during evacuation in fire safety regulations, research reports and such. Swedish, British, Australian and American fire safety regulations have been studied. A survey among Swedish fire safety consultant companies has also been carried out to investigate if there are agreement on the period of acceptable queuing time or how to assess it.

The conclusion is that there have been very few attempts to define the acceptable queuing time during evacuation considering the occupants’ experience of not being able to evacuate without delay. To gain more information about peoples’ willingness to queue during evacuation five experiments were made where egress from concert buildings were studied. The aim of these experiments was to measure individuals’ experience of the situation in relation to the time they had spent queuing to the exit. (Less)
