Safety Training

Why and how to enrol in a course


Safety training courses are mandatory for:


You can follow online courses directly within the SIR catalogue.

To be enrolled in a classroom course, you should launch a training request for a session within the CTA catalogue. The request is automatically transferred to the EDH form "Internal Training Request", which has to be signed at the end by you (the requester), your supervisor and your Departmental Training Officer (DTO).

It is important to note that most of the safety courses’ validity is limited in time. Therefore we offer refresher courses that have to be followed before the expiring date in order to avoid the loss of the rights listed in the “WHY” part.

You can find an attestation of training participation on HRT. Please note that this attestation only certifies your attendance at the course and it has no legal value.

For questions, requests or incidents, please refer to CERN's Service Now portal.
