Tunnel Safety Audits

Risknowlogy cooperates with the Dutch government to audit new and revamped tunnels concerning functional safety and SIL aspects. Several audits according to IEC 61508 have been carried out on the tunnel technical installations and related work. Any installations needed to achieve safe operating tunnels can be subject to SIL and thus IEC 61508. This includes for example smoke and fire detection, height protection, and more.

An overview of SIL and functional safety related tunnel projects is given below:
