Kumm, M. (2010). Carried fire load in mass transport systems. A study of occurrence, allocation and fire behavior of bags and luggage in metro and commuter trains in Stockholm. Forskningsrapport 2010:4 (på engelska och svenska) i serien Studies in Sustainable Technology vid Mälardalens högskola.
Abstract
A fire in an underground mass transport system is a great challenge for the fire and rescue services. The outcome of both the evacuation and the fire and rescue operation is dependent of the fire behavior. The fire load will influence the duration of the fire and the possible damage on the construction. It will also affect the fire and rescue services possibilities and need to extinguish the fire.
When designing new trains high fire safety requirements are raised on the carriage, the interior and the used material. The fire accidents in the Baku Metro in 1995 and in the funicular railway in the Kaprun tunnel in 2000 shows that the carried fire load also has a great impact of the fire.
In this report the carried fire load in the Baku and Kaprun fires are discussed and the occurrence and location of carried fire load in the Stockholm mass transport systems is described. Based on the field study in Stockholm typical bags and luggage have been chosen and fire test have been performed at SP Technical Research Institute of Sweden. The test includes different sizes of bags and luggage with representative contents as well as prams and shopping bags.
