Ingénieur INSA maîtrise des risques industriels et impacts sur l’environnement. First CERN (Risk analysis Isolde) Mission: Propose procedures to minimize risk of accidents, prepare emergency plans and finalize the safety file to document the work Define specifications for the operation of the facility and the safety issues involved. This will include remote handling operations and handling of the radioactive waste as a results of the tests Analyze, determine and specify the procedures and safety documentation that will be required for each experiment prior their approval for beam time in the facility Coordinate the operational safety aspects of the facility including the defining of intervention protocols and reporting on operations in terms of safety. Act as safety linkman and collaborate with the various safety groups at CERN
