Safety actors in a project @CERNA not exhaustive, simplified overview  • Safetyfollows the hierarchical line • Safetyresponsibilitiescannotbedelegated Project leader Project Safetyofficer DepartmentHeads DepartmentalSafetyofficers Workpackage leader Workpackage leader Workpackage leader Group Leader Group Leader Group Leader Group Leader PL isresponsible for Safety withinhis Project Responsible for Safety of projectsundertheirresponsibility Responsibilitiesshall in no way replace the Safetyresponsibilities of the line management of the Departmentsinvolved Regulator for CERN Project Correspondents (Conventionnal and RP) HSE Christelle Gaignant – ITSF2019 @ESS Lund – EDMS 2153979

  4. The context: a projectwith « major Safety implications » • HSE classified HL-LHC as a projectwith "major Safety implications" • HSE actions as a result: • Edit the « LaunchSafety Agreement » : list of (conventional) safetyrules to complywith for each item • List of safetychecks • Issue the HSE safety clearance Christelle Gaignant – ITSF2019 @ESS Lund – EDMS 2153979

  5. The context: the deliverables • HL-LHC deliverables are of differentkinds, amongstwhich : • Objectsbuilt for HL-LHC specificneeds, and no particularsafety challenges, • Innovative, one of a kind, neverseenbeforeobjects • Eachdeliverablemaybe: • A CERN design, manufacture and assembly • From the industry • From in-kind contributions • A mix of above Christelle Gaignant – ITSF2019 @ESS Lund – EDMS 2153979

  15. Abstract The High Luminosity LHC (HL-LHC) is an upgrade of the LHC to achieveinstantaneousluminosities by a factor of five largerthan the LHC nominal value, therebyenabling the experiments to enlargetheir data sample by one order of magnitude comparedwith the LHC baseline programme. The HL-LHC projectdeliverablesrankfrom standard industrialequipment to innovativeunprecedented technologies, involvingexternalpartners in the industry and from Collaborations. The HL-LHC Safety Office developed, in collaboration with CERN HSE unit, a systematic and scaledapproach of riskassessments. Existingrisk identification and evaluationprocesses have been revised and updated to ensure an optimized use of resources to target the safety challenges of this large-scaleproject. This talk willpresent the riskevaluationprocess, as well as the workflow and information exchange between the differentstakeholders. A particular attention isalsopaid to documentation and itsarchiving to allowaccess and retrievalduring the design, installation, commissioning and operation of the different hardware. The scalability of the methodwillbeillustratedwithexamplesfrom a givenequipment to an assembly of components and up to a facility. Christelle Gaignant – ITSF2019 @ESS Lund – EDMS 2153979

The context: the deliverables • HL-LHC has differentkinds of deliverables • Activities (manufacturing, assembly, etc.) • New buildings (surface and underground) • Supply of standard equipment • Innovative, one of a kind, neverseenbeforeobjects • Objectsbuilt for HL-LHC specificneeds, and withoutspecificsafety challenges.
