Safety Training: a right or an obligation?

CERN’s Safety Training programme currently offers around 50 classroom courses and 17 e-learning courses. Although anyone can attend any of these courses, some are compulsory for everyone working at CERN. In particular, “CERN Safety Introduction” and “Safety during LS1” are compulsory for all new arrivals.

However, depending on the type of activities, the type of workstation, the role you have been assigned (TSO, project leader, etc.) and/or the area where you will be working (e.g. confined spaces), you might be required to follow additional safety training provided by CERN.

In accordance with the provisions of the CERN Safety Policy, members of the personnel must keep themselves informed of their obligations in terms of safety training and of the actions they must take to keep up to date. Most training courses are valid for three years, and as they reach the end of their validity a reminder is automatically sent to the people concerned. It is important to sign up as soon as possible for refresher sessions when you receive such a reminder or you might (for example) risk losing your access authorisation.

The Training Catalogue and the SIR (Safety Information Registration) site provide details of the training courses you must complete. These tools can be consulted at any time and are managed by the Safety Training team in the HSE Unit in partnership with the HR-LD and GS-AIS Groups. They are designed to be easily accessible for everyone. However, if you have any questions, you can contact the Safety Training team by phone (73811 or 79935) or by e-mail (
