Safety in Construction and Upgrade Phases Thomas Otto, Departmental Safety Officer, Technology Department CERN-ITER Workshop, 16 January 2017

CERN-ITER Worsksop 16 January 2017 Outline Scope Who is in charge ? (Safety Organisation @ CERN) Plan ahead ! Preventive Safety actions Conformity / Preventive Workplace Safety ALARA (Safety) training Scheduling VIC Summary Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

CERN-ITER Worsksop 16 January 2017 Scope Long Shutdown Commissioning Operation Technical Stop YETS 2015 1 EYETS 2016 2 * YETS 2017 3 LS2 4 CERN accelerator complex characterised by operation phases and maintenance / upgrade phases (Shutdowns) During Shutdowns, several upgrade projects work in parallel Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

Two aspects of Safety Conformity Preventive Workplace Safety Equipment Process Standards (ISO, EN, Eur. Dir….) Safety Rules, best practice Inspection Hazard identification, risk assessment Report on non-conformities Safety Report, action list Make conform Apply rules and best practice Conformity marking User manual Procedure manual Training in use of equipment Training the process Safety Training Personal Protective Equipment Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

CERN-ITER Worsksop 16 January 2017 Conformity Issues Conformity: an item meets the essential requirements of a given (safety) standard “Equipment X is conform to Standard EN 1234” Have all relevant items inspected HSE unit inspection service Make conform, where necessary Technical measures Technical documentation and manuals Train workers Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

Preventive Workplace Safety Workplace Safety ascertains that a worker uses a conform equipment in a safe way Risk Assessment of relevant processes Technical experts Safety (support) officers HSE unit experts Put into place recommended actions Establish process manuals Train workers Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

What to consider relevant ? Equipment and tools which are Significantly modified by CERN entirely developed by CERN therefore, bear no CE marking Operations and Processes of high complexity involving unique equipment, tools, methods taking place in special environments Industry-type work by contractors is covered in PP Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

Documentation of Procedures Comprehensive documentation Achieve and maintain high quality Basis for technical training Facilitates the hazard and risk assessment processes Include safety-relevant messages: warnings, interdictions, use of PPE Successful example LS1 SMACC project CERN-ITER Worsksop 16 January 2017

ALARA, radiating shining example Radiation dose estimation based on preliminary work plan The ALARA dose optimisation process Based on a process description (with timing) Collaboration between executing unit and HSE-RP Optimisation of a measurable objective (dose) Other safety aspects often included: asbestos, physical constraints, … An example of successful safety prevention Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

CERN-ITER Worsksop 16 January 2017 Safety Training Formal Training (HSE unit) Capacities limited Plan requirements ahead Language issues must be resolved On-the-job training (Supervisor’s responsibility) For processes and equipment Allow sufficient time in schedules Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

Scheduling helps Safety Time pressure & stress are bad Safety advisors Keep suitable Safety margin you assure that the work can progress safely and within the planned schedule Correct Scheduling minimises co-activities Safety role of CERN’s coordination team CERN-ITER Worsksop 16 January 2017

Visite d’Inspection Commune By professional Safety Coordinator or by the “Works and Services Supervisor”* Legal requirement when engaging French contractors Coordination of co-activities Takes place shortly before intervention Too late to make important changes If not successful, delaying the start of works *GSI-WS-1, “Safety coordination for works and services” confers safety coordination to the organic unit in charge of the works / service contract Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

Day-to-day coordination Clearly define roles in work area One (and only one) person with a clear mandate shall coordinate the work All work orders pass by the coordinator Avoid potentially dangerous co-activities CERN-ITER Worsksop 16 January 2017

Monitoring & feedback during execution Safety “walkthroughs” in work areas Accumulated dose reports from ALARA operations Feedback on working procedures In case of incidents and accidents: Investigation (obligatory for personal accidents with > 1 day absence) Lessons learnt Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

CERN-ITER Worsksop 16 January 2017 Summary CERN has gained operational Safety experience in large projects such as LHC installation Long Shutdown 1, SMACC Safety is a collaborative effort of all units Specific safety roles of Safety officers Central coordination HSE unit Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017

CERN-ITER Worsksop 16 January 2017 Summary LS2 is the umbrella to Accelerator upgrade projects Consolidation projects Routine maintenance A Safety Framework is developed, based on Conformity & Preventive Workplace Safety Adequate (Safety) Training The (well-known) hierarchical line of Safety responsibility remains in place, with support from Projects, Coordination and HSE unit Thomas Otto, TE DSO CERN-ITER Worsksop 16 January 2017
