- Abstract (Swedish)
- Stockholm Arlanda Airport är Sveriges mest använda flygplats och terminal 4 är en av flygplatsens mest använda terminaler. Verksamheten bedrivs dygnet runt och antalet personer är mycket varierande. I denna rapport utvärderas säkerheten i händelse av brand i terminalens incheckningshall med avseende på personsäkerhet.
Flera möjliga brandscenarier identifierades med bakgrund i information från ett platsbesök samt tillgänglig statistik om branduppkomst. Scenariernas sannolikhet och konsekvens bedömdes kvalitativt och med hjälp av en riskmatris valdes sedan följande 3 scenarier ut för vidare undersökning:
Scenario A – Brand startar i en soptunna vid huvudentrén vilket leder till att en utrymningsväg blir obrukbar.
Scenario B – Brand... (More) - Stockholm Arlanda Airport är Sveriges mest använda flygplats och terminal 4 är en av flygplatsens mest använda terminaler.

Flera möjliga brandscenarier identifierades med bakgrund i information från ett platsbesök samt tillgänglig statistik om branduppkomst. Scenariernas sannolikhet och konsekvens bedömdes kvalitativt och med hjälp av en riskmatris valdes sedan följande 3 scenarier ut för vidare undersökning:
Scenario A – Brand startar i en soptunna vid huvudentrén vilket leder till att en utrymningsväg blir obrukbar.
Scenario B – Brand startar i en resväska i kön till incheckningsdiskarna.
Scenario C – Brand startar i elektriska installationer i en incheckningsdisk.
Effekten av brandscenarierna simulerades med FDS och Pyrosim för att bestämma Available safe evacuation time (ASET). Utrymningsförloppen, Required safe evacuation time (RSET), simulerades med Pathfinder. ASET och RSET jämfördes och en säkermarginal räknades ut. En känslighetsanalys genomfördes på utvalda parametrar i utrymningssimuleringen för att avgöra betydelsen av variationer i ingående data.
Resultatet visar att byggnaden kan utrymmas säkert i alla tre scenarier och att kritiska förhållanden endast uppnås efter lång tid i scenarierna B och C. Om det finns en ambition att öka brandsäkerheten ytterligare rekommenderas följande åtgärder:
• Utbildning av personal och införande av riktlinjer för utrymning.
• Förbättra placering, funktion och antal detektionssystem. (Less) - Abstract
- Stockholm Arlanda airport is the busiest airport in Sweden and Terminal 4 is one of the airports most frequently used terminals. The business is running through all hours of the day and the number of occupants is largely varying. In the following report the fire safety of the check-in and bag drop area is evaluated regarding the occupant’s safety.
Several possible fire scenarios were identified using information obtained during a site visit and available statistics on fire incidents. A risk matrix was used to qualitatively assess the plausibility and the severity of the consequence of each scenario. Subsequently, the following three scenarios were chosen for further evaluation:

Several possible fire scenarios were identified using information obtained during a site visit and available statistics on fire incidents. A risk matrix was used to qualitatively assess the plausibility and the severity of the consequence of each scenario. Subsequently, the following three scenarios were chosen for further evaluation:
Scenario A – Fire starts in a trash bin next to the main entrance rendering one of the main exits from the building unusable.
Scenario B – Fire starts in a suitcase in the bag drop area.
Scenario C – Fire starts in electrical installations in the check-in disc area.
Using FDS and Pyrosim, the effects of the fire scenarios was simulated to determine the available safe evacuation time (ASET). The required safe evacuation time (RSET) was simulated using Pathfinder. ASET and RSET was compared, and a safety margin was calculated. A sensitivity analysis on key parameters regarding the evacuation was performed to determine the importance of varying input data.
The results show that the building can be evacuated safely in all three scenarios with critical conditions only ever occurring after a long time in Scenarios B and C. If there is an ambition to increase the safety regarding a fire incident, the following measures are recommended:
• Education of personnel and implementing a guideline for an evacuation procedure.
• Improve placement, function and number of detection systems. (Less)
