Brandteknisk riskvärdering av Orkanen i Malmö
(2022) VBRN70 20221Division of Fire Safety Engineering
- Abstract (Swedish)
- Orkanen i Malmö är en universitetsbyggnad som består av fem tillgängliga våningsplan och ett källarplan. Det finns även våning sex och sju, de är dock inte är tillgängliga för studenter eller allmänheten. Genom platsbesök, tillgänglig litteratur kopplat till anläggningen och genom en kontaktperson utvärderas brandskyddet i Orkanen ur ett personsäkerhets perspektiv.
Utvärderingen sker genom att möjliga brandscenarier identifieras och värderas utifrån skalor för sannolikhet och konsekvens. De tre mest kritiska scenarierna väljs för vidare analys där handberäkningar och simuleringar för dessa scenarier genomförs. Handberäkningar görs för att uppskatta effektutveckling och brandgaslager.

Genom platsbesök, tillgänglig litteratur kopplat till anläggningen och genom en kontaktperson utvärderas brandskyddet i Orkanen ur ett personsäkerhets perspektiv.
Utvärderingen sker genom att möjliga brandscenarier identifieras och värderas utifrån skalor för sannolikhet och konsekvens. De tre mest kritiska scenarierna väljs för vidare analys där handberäkningar och simuleringar för dessa scenarier genomförs. Handberäkningar görs för att uppskatta effektutveckling och brandgaslager. Brandscenarierna simuleras i FDS för att få fram olika kritiska förhållande, där simuleringarna är baserade på de framräknade effektutvecklings-kurvorna. Utrymningssimuleringarna genomförs i Pathfinder där tid för utrymning i de tre scenarierna undersöks.
I alla tre scenarierna visar sig brandskyddet vara fullt tillräckligt då sprinkleraktivering fungerar. Dock efter att brandförlopp och utrymning jämförts när sprinkler inte fungerar visas det att kritiska värden i godsmottagning uppnås innan utrymning slutförts när sprinkler inte fungerar. Detta medför att rekommendationer för alternativa åtgärder ges för att öka robustheten av brandskyddet i godsmottagningen. (Less) - Abstract
- The purpose of this report is to evaluate the fire safety of the university building Orkanen Malmö as an educational part of the course Fire Risk Assessment (VBRN70) at Lund University (LTH). Limited to the safety of occupants in the building, the report does not take economic or structural damage into account.
To begin with, the building was investigated during a guided tour where photographs were taken, information was given, and questions were answered. With information from the tour and given literature about the facility, a fire safety evaluation was conducted. This fire safety evaluation proceeded through testing if evacuation could be done without compromising the safety of the occupants, in three different scenarios. These three...

To begin with, the building was investigated during a guided tour where photographs were taken, information was given, and questions were answered. With information from the tour and given literature about the facility, a fire safety evaluation was conducted. This fire safety evaluation proceeded through testing if evacuation could be done without compromising the safety of the occupants, in three different scenarios. These three scenarios were chosen from ten originally identified scenarios, in which a possible fire could take place. All scenarios were evaluated through a scale of probability and a scale of consequence, of which the three most critical scenarios were chosen.
In each of the three scenarios, heat release rate and height of smoke layer was calculated and an evacuation simulation in Pathfinder and a fire simulation in Fire dynamics simulator (FDS) was conducted. The fire simulation was modelled without the activation of the currently installed sprinkler-system.
Required safe egress time (RSET) was given through the evacuation simulation and available safe egress time (ASET) was determined through the fire simulation. Comparing RSET and ASET, two out of three scenarios had a positive result. In the third scenario however, critical levels in certain parameters were reached before the evacuation was completed. With consideration of the installed sprinkler-system, a conducted heat release rate curve for all scenarios shows that none of the three scenarios will be close to critical levels. The fire safety is overall good but to improve the fire safety even further, two alternative recommendations is given to the specific location where the scenario with critical levels (in absence of sprinkler) occurred.
