Övertändning, backdraft och brandgasexplosion sett ur räddningstjänstens perspektiv

This report presents a detailed description of the phenomena flashover, backdraft and smoke gas explosion. The physical and chemical processes which are involved in these phenomena are thoroughly discussed. The report also describes a number of compartment fire scenarios which are believed to be the most common scenarios occurring in Sweden. The description is based on a number of full- scale experiments which were carried out within the project. At the end of the report, possible warning signs of a potential flashover and backdraft are discussed. In the appendices, a number of models used to predict flashover are evaluated, using data from small scale experiments carried out within the project.
