Newcomers measures and requirements - COVID-19

    Prior to accessing the CERN site, you will need to complete the following steps:

    1. Pass the CERN COVID-19 Training Course
      All newcomers coming on the CERN sites have to pass a compulsory COVID-19 Health and Safety Measures at CERN training course in order to access the CERN sites. 
      This course is available from the Learning Hub.
    2. Sign the CERN COVID-19 Self-Declaration
      All newcomers coming on the CERN sites must sign a form to declare that they have read and understood the current COVID-19 related access restrictions in force at CERN.
      Please read the accompanying Instructions before signing the declaration.
      → The Declaration is available here in English and in French and must be provided to Building 55.

    3. Familiarise yourself with the COVID-19 measures in place on site. They are available on the HSE page and FAQ , as well as on the Users’ Office dedicated page.

    4. Take careful note of the quarantine imposed by CERN
      All members of personnel returning from one of the countries mentioned in at least one of the lists of countries and areas with a high risk of coronavirus infection published by the Swiss or French authorities will not be allowed on CERN sites for 10 days after the date of their return. Please read the information about travel restrictions in Switzerland and France and consult the FAQ related to travel and leave matters.  

    5. Contact your Experiment / Group Secretariat for instructions on how to collect your Personal Protection Equipment (face masks, hydro-alcoholic sanitizer, etc.) upon your arrival at CERN and book an appointment to collect your Proximeter device.

    6. Contact your Supervisor a few days before traveling for a final confirmation that your presence on site is still required and approved by your hierarchy (Technical Coordinator or Spokesperson for Users, Department Head for COASs and VISCs).
