Popular Abstract in Swedish

Riskanalys och insatsplanering är viktiga delar av ett riskhanteringsarbete. Denna studie har visat att det är möjligt att använda brandtekniska ingenjörsmodeller för att bedöma utvecklingen av bränder och det uppkomna behovet av släckmedel. Brandkårsdata från London användes för att studera sambandet mellan brandstorleken och räddningstjänstens insats. Dessa data, tillsammans med två gamla undersökningar, användes också för att utvärdera tillgängliga modeller för att dimensionera släckinsatser med vatten. Publicerade experiment i mindre skala studerades också. En experimentell undersökning av släckkapaciteten hos högtrycks- resp. lågtrycksstrålrör vid stora bränder gjordes. Då studerades också...

Då studerades också värmepåverkan på rökdykare. Gasformiga släckmedel studerades även, främst avseende hur extern strålning påverkar den nödvändiga släckmedelskoncentrationen. (Less)
Abstract
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. Data from the London Fire Brigade (UK) were used to investigate a possible correlation between the area of the fire and the fire-fighting measures employed. This data, together with data from two old investigations, published in the literature, were used to evaluate existing models for the dimensioning of manual fire suppression using water. The demand for water was also investigated theoretically and experimentally. Theoretical investigations... (More)
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. Data from the London Fire Brigade (UK) were used to investigate a possible correlation between the area of the fire and the fire-fighting measures employed. This data, together with data from two old investigations, published in the literature, were used to evaluate existing models for the dimensioning of manual fire suppression using water. The demand for water was also investigated theoretically and experimentally. Theoretical investigations were carried out using data from small-scale tests found in the literature, and data from real fires in London (UK). Experimental studies were carried out employing large-scale suppression tests in order to evaluate the difference in efficiency between a low-pressure and a high-pressure nozzle. The heat stress on the fire fighters was also studied. Apart from water, gaseous extinguishing media were also investigated with regard to the effect of external heat radiation on the required medium concentration. (Less)
