Fire Suppression in Road Tunnel Fires by a Water Mist System – Results of the SOLIT Project

Published:  14 April, 2010

The Project SOLIT – Safety of Life in Tunnels was sponsored by the Federal Ministry of Economics and Technology (BMWi) of Germany. The main content was the development and the test of a high pressure water mist system for fire fighting in tunnels. The protection objectives were the following:
- Improving the chances of self-rescue for involved persons,
- Preventing any further progression of the fire,
- Enabling the fire brigade to rescue injured persons, permitting to carry out remaining
extinguishing activities
- Protection of the tunnel construction.

A short report was given on the last ISTSS conference [1]. The IdF took charge at the design and installation of the measuring system as well as the evaluation of measuring data. Results of the experiments will be shown on the bases of the measured quantities and graphics. In particular, the fire suppression by the water mist fire fighting system is considered. Different assessments for the heat release rate (HRR) take centre stage [2-5]. The achievement of the protection objectives will be discussed.
