Abstract

Close
- A total of six fire tests were conducted in a mock-up of a subway carriage that is about 1/3 of a full wagon length. They were carried out under a large scale calorimeter in a laboratory environment. The aim of the tests was to investigate the initial fire growth in a corner scenario using different types of ignition sources that could lead to a flashover situation. The ignition sources used were either a wood crib placed on a corner seat or one liter of petrol poured on the corner seat and the neighboring floor together with a backpack. The amount of luggage and wood cribs in the neighborhood of the ignition source was continuously increased in order to identify the limits for flashover in the test-setup. The tests showed that the combustible boards on parts of the walls had a significant effect on the fire spread. In the cases where the initial fire did not exceed a range of 400 – 600 kW no flashover was observed. If the initial fire grew up to 700 – 900 kW a flashover was observed. The maximum heat release rate during a short flashover period for this test set-up was about 3.5 MW. The time to reach flashover was highly dependent on the ignition type, wood cribs or backpack and petrol.
