Abstract
This report is an evaluation of the egress safety in Upplands-Bro gymnasium which is situated in the Stockholm region. The school was originally designed for 600 pupils but the number has increased and today 950 pupils are attending the school. The increased number of pupils creates a more difficult egress situation and the fire service was therefore interested in an evaluation. Different fire scenarios were studied and three were chosen regarding the effect on egress and the likelihood of the scenario. These scenarios are meant to include the effects of all likely fire scenarios in the object. The time to reach untenable conditions was simulated with CFAST and/or with hand calculations. The time for egress was simulated with SIMULEX and a... (More)
This report is an evaluation of the egress safety in Upplands-Bro gymnasium which is situated in the Stockholm region. The school was originally designed for 600 pupils but the number has increased and today 950 pupils are attending the school. The increased number of pupils creates a more difficult egress situation and the fire service was therefore interested in an evaluation. Different fire scenarios were studied and three were chosen regarding the effect on egress and the likelihood of the scenario. These scenarios are meant to include the effects of all likely fire scenarios in the object. The time to reach untenable conditions was simulated with CFAST and/or with hand calculations. The time for egress was simulated with SIMULEX and a comparison was made between the two. In case of a fire the biggest problem, from an egress point of view, will be the vegetation outside the emergency egress windows. If the vegetation is removed, the school is to be considered safe. Recommendations are given how to increase the overall safety such as installing smoke alarms and better evacuation signs.1 (Less)
