Brandteknisk riskvärdering av köpcentret Gallerian i Västerås

Sammanfattning: This report evaluates personal safety during evacuation of the arcade Gallerian, Västerås, in case of fire. The report focuses on evacuation through Gallerian’s main paths. During a visit to the arcade potential fire scenarios and current fire protection systems were identified, and a survey was handed out to some of the staff members. The results from the survey concluded that some of the staff were lacking sufficient knowledge of current routines in case of fire, however most of the staff were well aware of the routines. In order to determine if there was a risk for personal safety three design fires were further examined and analyzed through hand calculations, statistics and simulations in computer programs. Results from the analyzed design fires were compared to levels of critical conditions and the required time to evacuate to find out if the evacuees were in risk of harm. The report concludes that the personal safety in the arcade is adequate. Despite this, one measurement was found to be required by Swedish fire safety legislation – to install a proper notification sign next to an unmarked fire extinguisher. Other measurements which were not required by law but would improve the personal safety were also brought up. These measurements were related to the results from the survey, repairing smoke hatches, investigating a certain lighting equipment’s effect on sprinkler and general sprinkler maintenance.
