6. 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

CERN-ITER Worsksop 16 January 2017

7. 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

8. 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

9. 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

10. 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

11. 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

12. 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

13. 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

14. 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

16. 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

17. 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

18. 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

19. 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
