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

7. Thomas Otto LS2 General Safety
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
LS2 Committee
Thomas Otto LS2 General Safety

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
LS2 Committee
Thomas Otto LS2 General Safety

9. What to consider relevant ?
Equipment and tools which are
modified by CERN
entirely developed by CERN
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

10. Thomas Otto LS2 General Safety
CERN’s Diversity
LS2 takes place all over CERN:
LHC, SPS, PS, PSB, LINACS
Surface facilities
All technical and physics departments
Different history, different “culture”, different persons (and personalities)
LS2 Committee
Thomas Otto LS2 General Safety

11. Harmonised Approach to Safety
The LS2 Coordination and its Safety Support Officers promote a Harmonised Approach to Safety:
Same principles of Safety organisation (who is in charge, coordination, follow-up)
Same effort in preparation and prevention for similar type of work
Same prerequisites for access
(exceptions justified by lower / higher Safety risk)
Same rules for everybody
LS2 Committee

12. Thomas Otto LS2 General Safety
Safety Training
Formal Training (HSE unit)
Capacities limited
Plan requirement ahead (personnel scheduling)
Language issue unresolved
On-the-job training (Supervisor’s responsibility)
For processes and equipment
Include in schedules
LS2 Committee
Thomas Otto LS2 General Safety

13. Prevention of Radiation Risk (ALARA)
The ALARA dose optimisation process
Based on a process description (with timing)
Collaboration between executing unit and HSE
Optimisation of a measurable objective (dose)
Other safety aspects often included: asbestos, physical constraints, …
An example of successful safety prevention
Frequently necessary in LIU projects

14. Visite d’Inspection Commune
By professional Safety Coordinator or by the “Works and Services Supervisor”
Focus on coordination of co-activities and high-risk activities
Takes place shortly before intervention
Too late to make important changes
If not successful, delaying the start of works

16. Thomas Otto LS2 General Safety
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
The LS2 Safety Support Officers will work to harmonise the Safety approach over projects, facilities and departments.
