In the frame of a Swedish national and a European research program, UPTUN, on tunnel safety, comprehensive large scale fire tests have been carried out in the abandoned Runehamar road tunnel in the Western part of Norway in September 2003.

Semi-trailer fires, similar to the size of the recent fires in Mont Blanc Tunnel (France/Italy) and St Gotthard Tunnel (Switzerland), have been particularly considered. The tests have been conducted by the Swedish National Testing and Research Institute (SP) in collaboration with the UPTUN partners: TNO (is now called Efectis) Building and Construction Research from the Netherlands and the Norwegian Fire Research Laboratory (SINTEF/NBL).

A report containing the set-up of the tests, the recordings of the data and the interpretation of the results was issued by Uptun, TNO and our company.

The report also contains a cd-rom with all the pictures and video’s of the set-up and the fire tests, as well as all the technical/scientifical papers.
