Brandteknisk riskvärdering av Storsjöteatern i Östersund

Sammanfattning: This report is a fire safety evaluation of Storsjöteatern in Östersund, Sweden, which is a theatre combined with conference rooms. Only human evacuation safety is taken into consideration in the report. There is no emphasis regarding economic and environmental aspects or the durability of the building after evacuation has taken place. The objective was to achieve a satisfying evacuation of the building in case of fire. The analysis began with an evaluation of the building and its existing fire protection. Possible fire scenarios were estimated and evaluated in regard to probability and consequence. Three fire scenarios were picked out for further investigation because of their significance regarding evacuation safety. Two of the scenarios were handled with a probabilistic approach and one scenario was handled with a deterministic approach. The fire safety of certain sections of the building was found insufficient regarding the objective of satisfying evacuation. The evaluation resulted in several proposed actions to enhance the fire safety of the building. The actions were validated contrary the objective to prove that they made evacuation safe in the analyzed scenarios.
