• Creating incident analysis reports and follow up the resolution of the related action plan.
• Participating to periodic meetings related to safety matters and interact with other Safety Officers and stakeholders.

Any specific knowledge in a certain safety domain (fire, chemical, cryogenic, etc.) could be translated into the role of a Specialised Safety Officer, to support the Safety Office in the assessments related with that domain.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on
