In addition our indoor lab, we also have a 3,000 m2 at our disposal for full-scale fire testing. In the area we have a 60-meter-long tunnel facility to study fire dynamics in tunnels and enclosed spaces. The tunnel can also be used to determine the properties of materials and products in the event of fire or temperature impact on a larger scale. Furthermore, the tunnel facility can also be used to test different extinguishing systems. In this area, we also conduct research on risks related to the use of hydrogen.
