Fire tests in the Neuchâtel tunnels: mission accomplished!
published onNovember 30, 2017

The new ventilation equipment in the A5 motorway tunnels under Neuchâtel in Switzerland has now been subjected to testing.

Hot smoke tests were carried out over three nights, so as to test user evacuation and smoke extraction scenarios based on various significant outbreak locations. In total, six outbreak sites were tested. These tests represent the final stage in renovating the ventilation system of section 6 of the Neuchâtel tunnels.

By 2019, the entire subterranean Neuchâtel network will be fitted out, and all equipment renovation work will have been conducted without interruptions to operations.
