Access Conditions for Visitors

The document General Safety Instruction GSI-SH-1 Visits on the CERN site (EDMS 1137263), defines the minimum requirements for all types of visits on CERN site.

This Safety Instruction is complemented by the Safety Guideline SG-SH-1-0-1 (EDMS 1534426) for the its implementation.

For each visit, the following is defined:

• an official responsible for the organisation of the visit, who is the guarantor of compliance with CERN Safety rules. For professional visits of facilities, the person responsible for the visit can, exceptionally, be a contractor, subject to authorisation by the CERN contract manager;
• at least one escort – this may be the visit organiser;
• the number of visitors admissible in the group;
• the special conditions applying to the visitors, where they exist;
• the areas visited and/or to be passed through which are accessible;
• the safety equipment for the visitors and/or the escort(s).

The conditions of visits must be suited to the physical and mental aptitudes of the visitors (e.g. problems of reduced mobility, claustrophobia, etc.).

The Safety file template for event-based visits (EDMS 2235038) is to fill in at least three weeks before the event take place and submitted via EDMS to HSE, DSO and TSO before approval by the Group Leader and release in EDMS.

Professional visits of facilities

A professional visit is an escorted visit organised in the framework of a professional assignment or an official guided visit requalified, by the Head of the HSE Unit, as a professional visit of facilities following a duly justified request.

The instructions are detailed in the document Steps to follow when organising a professional visit of CERN’s installations (EDMS 1281098).

These instructions do not apply to press visits.
