(Excerpt from the European tunnel security guideline)

For each tunnel, whether it is in the design, construction or operating stage, the administrative authority shall identify as Tunnel Manager the public or private body responsible for the management of the tunnel at the stage in question. The administrative authority itself may perform this function.

For each tunnel, the Tunnel Manager shall, with the prior approval of the administrative authority, nominate one Safety Officer who shall coordinate all preventive and safeguards measures to ensure the safety of users and operational staff. The Safety Officer may be a member of the tunnel staff or the emergency services, shall be independent in all road tunnel safety issues and shall not be under instructions from an employer in respect of those issues. A Safety Officer may perform his/her tasks and functions at several tunnels in a region.
