  1. 11. Demand for Extinguishing Media in Manual Fire Fighting

    Författare :Stefan Särdqvist; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fire fighting; Fire brigade; fire suppression; extinguishing agents; extinction; Technological sciences; Teknik;

    Sammanfattning : Risk analysis and intervention planning are important in fire prevention and risk management strategies. This study has shown that it is possible to use fire safety engineering models to estimate the development of fires on a realistic scale, and the corresponding requirement for extinguishing media.

  3. 12. Uncertainty and Risk Analysis in Fire Safety Engineering

    Författare :Håkan Frantzich; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event tree; fire engineering design; reliability index; FOSM; Monte Carlo simulation; Risk analysis; uncertainty analysis; response surface.; Technological sciences; Teknik;

    Sammanfattning : Two Quantitative Risk Analysis (QRA) methods are presented which can be used to quantify the risk to occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. LÄS MER

  4. 13. Evaluation and Mitigation of Industrial Fire Hazards

    Författare :Petra Andersson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Effect of fires; Accidental release; Water mist; Halon replacement; Industrial Fire Hazards; Human burns; Smoke detektion;

    Sammanfattning : A tool suitable for conducting industrial fire and explosion hazard analysis is presented, together with an identification of weak links in the hazard evaluation chain. For some of the weak links additional research has been carried out. LÄS MER

  5. 14. Determination of Material Properties for Fire Modelling

    Författare :Ulf Göransson; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material properties; Material degradation; Measurements; Fire test data; Byggnadsteknik; Building construction; Teknik; Technological sciences; Fire; Surface temperature; Mathematical modelling;

    Sammanfattning : Fire and flame spread are very complex phenomenon to study. Several aspects need to be considered and treated. In order to be able to do a correct analysis of the flame spread phenomenon, which is necessary to be able to predict flame spread, knowledge of material properties are needed. Material properties can be obtained in different ways. LÄS MER

  7. 15. Experimental measurements of water mist systems and implications for modelling in CFD

    Författare :Bjarne Husted; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; fire suppression; CFD; FDS; fire safety engineering; PDA; water mist; PIV;

    Sammanfattning : The use of water mist for fire extinguishment has increased rapidly in recent years. The main reason is the abandonment of halon-based extinguishing systems in favour of environmentally friendlier systems. Furthermore the use of water mist systems has spread from mainly marine applications to also include the protection of buildings. LÄS MER
