• Executing the works while fulfilling Safety rules and mandatory trainings is a line management
responsibility! But when guidance/rules are needed… where to go? No clear single point of truth.
• HSE, PSO, DSO, SSO, Group Safety link person, EROS, …
• Difficult to understand who is in charge of what, who is responsible of what?
• PSO vs Technical stop safety coordination who has the authority on what?
The role of the PSO is different wrt projects due to ad-hoc execution delegations
• For LIU clear interface and responsibilities
• For HL, would need a better clarification (during LS2, for ex. , for UPR general services installation phase)
Simplification would empower understanding and effectiveness

Support and collaboration
HSE workshop 12th May 2021
Positive
• All users appreciated the joint Safety talks in the coordination meetings (SSO, DSO & EROS)
• HSE-OHS provided an efficient collaboration when required by groups for electrical, lead, asbestos inspections
• Sole channel of official communication should be ensured, in particular to externals.
• Severity is also to be taken into account. Avoid excessive on the spot reactions/decisions.
• Excellent support and collaboration from/with HSE-RP to treat the waste in the machines
• Implementation of specific waste sorting trainings
Possible improvements
• LS2 preparation phase:
• WorkPackageAnalysis:
• HSE-OHS participation required to expect particular safety recommendations but no comment/feedback received.
Feeling that OHS is not part of the collaborative and preventive approach to prepare LS2.
• HSE-OHS organization per project and not per Facility introduced complexity in the interface
• Pragmatic Recommendations needed to help in the preparation phase of the LS2, in term of safety, in order
to prevent risks/hazards issues (to avoid issues like the asbestos, the Pb paint, the structural
unconformities, inspections, …)
• Preparation and anticipation of the OHS activities with provisional schedule and related resources.
Handling & inspections not planned (last minute approach)
• Execution: Participation of HSE-OHS to the coordination meetings and feedback sessions
executive approach in the rule's definition
• Radioactive material transport: process to be ease
6. 6
Collaboration with HSE-FB
HSE workshop 12th May 2021
Positive
• Availability / Willingness of the HSE-FB to perform exercises in
the machines.
• Excellent collaboration with HSE-FB:
• Evacuation improvements (visits, advices, …) (SPS and PS SWY).
• Installation of new equipment, patrols during the pandemic, …
Possible improvements
• Develop a list of all the possible exercises that HSE-FB
would like to perform in the machines, develop a long-
term plan for all these tests, and appropriate level of
preparation with measurable objectives.
• New intervention procedures (fire safety), increased
involvement of HSE-OHS.
7. • The GSI-WS-1 generated lots of confusions/discussions inside Groups:
• The French and English versions are giving different interpretations of the rule.
• The role of the WSS has been understood and put in place with different manners in the Groups. It generates
lots of discussions on the understanding of the roles (still today).
• The WSS training was very efficient (ref. EROS/SSO feedback).
• Thanks to the collaborative work of the DSO/SSO/EROS, the role of the WSS was mainly clarified
and support given (ex. Safety talks).
• The roles of WSS was/is/remains unclear for certain situation of works. Nevertheless, all people
nominated as WSS during the LS2 have make a remarkable effort to endorse their roles and
prevent any accidents, mitigate potential issued during the LS2.
• Activity Technical Coordinator (ATC) role had to be added to cover the situation of parallel
activities with different Groups for same package of activities organization of common VIC
before starting works.
WSS
Presentation Title - Author (Affiliation) 7
8. • WSS – improvement proposals (How/Can HSE help?)
• WSS shall know the machine environment in advance of the activities start to ensure proper risk analysis
Internal Group organization
• Request for work authorization or electrical lock-out.
people need a clear risk analysis methods and procedure about electrical safety
Working Group being put in place by J.P. Burnet concerning electrical safety
• Anticipate the waste management (ex. put in place trainings for workers).
Refer to some of the good examples done during the LS2
• WSS vs. IMPACT declaration form.
roles and responsibilities in the use of IMPACT to be clarified by the DSOs and IMWG
• WSS training shall be mandatory for any WSS to understand their roles and responsibilities.
Internal Groups organization
• WSS training courses volume shall be adapted to the YETS/LS
Evaluation of the needs to start early in advance with enough sessions
• WSS should ask for the support of the EROS at least once to get a proper example of VIC report from Expert.
Personal organization of the WSS with EROS team
• Dedicated % of time should be allocated to the WSS to prepare and follow-up activities on-site. Keep an eye on
the housekeeping would help to ensure safety and prevent the issue of waste left in the machines.

• CERN was putting activities on hold, waiting for rules to resume interventions.
• Dept Heads harmonized the requirements for interventions inside the Departments.
• Difficulties to identify who should give the rules/instructions on what:
HSE/DSO/SSO/EROS/hierarchical line management/TSO, ….
Operational Safety embedded on General Safety, communication channels to separated?

• Definition of the mitigations of the Electrical hazards (VIC?)
The WSS ask a simple question:
HOW CAN I HAVE MY WORK PERMIT ???
NEW Working Group appointed from 2021
HSE workshop 12th May 2021

Pb & Asbestos
HSE workshop 12th May 2021
Positive
• Fast and fruitful collaboration to tackle the unforeseen.
• Excellent support to prepare a strategy to tackle the asbestos cleaning in the PS.
• Excellent strategy to have a central place to separate other materials from asbestos outside the
machines.
Possible improvements
• Despite that several technical visits were performed
before LS2 to prepare some works, the different
actors were not able to identify these two Safety
hazards – improve the WSS and Safety support
officers training on these two safety aspects;
• Make the asbestos and Pb surveys information
visible to the CERN WSS on a web interface (not
necessarily the results) – survey exists.
12. 12
• Line Management should continue enhancing presence and commitment at the
appropriate level on its direct and unique organic responsibilities to ensure:
• The conformity of infrastructures and equipment;
• The execution of works according to defined Safety rules;
• The proper level of training and awareness of dangers in the working areas.
• Too many types of Safety actors overlapping on each others responsibilities.
• Often because some of them going beyond their defined mandate.
• No defined hierarchy level between Safety roles.
• Single point of truth is needed:
• To avoid divergence in interpretation of rules vs recommendations vs guidance.
• Communication in particular those with consequences on the work execution or with
Externals should be controlled and should follow defined interfaces/persons
designated by HSE Head.
My personal feedback as LS2 Coordinator
HSE workshop 12th May 2021
13. 13
• General Safety has been a concern, in particular for:
• Common spaces/areas in particular outside, temporary infrastructures…
• NCs identifications and follow-up ahead of LS2 was not as effective as I
would have wished. Several problematics identified “on the flight”.
• Only one line of coordination demonstrated its efficiency. The LS2
Coordination was working in a strong and close collaboration with LIU and
other projects.
• Risk Management whenever possible instead of zero risk approach
Many thanks to all contributors and actors of the Safety during the whole period
of LS2 since 2015!
My personal feedback as LS2 Coordinator

15. • Positive
• HSE-RP submitted most of the DIMRs on behalf
of the DIMR Owners (ambiguity in the roles)
• Pragmatic approach to the low level DIMRs
even if the different inside the DIMR Level 1
doesn’t exist in the ALARA rules
Spread between DIMR estimation and real doses
YYYY-MM-DD
Presentation Title - Author (Affiliation) 15
• Possible improvements
• DIMR and WDP web based basic training to reach a large amount of WSS (being implemented)
• Make the dose rates available in a more flexible way to allow the departments to be more independent in
the preparation of DIMR and WDP
• Transfer more the responsibility to the DIMR owners (RSSO) to submit the DIMR and to follow-up
• Perform more regular surveys for long lasting works and adapt the DIMR to new measurements
• Officialise the difference of procedure inside the ALARA Level 1 DIMRs (Level 0 and Level 1)
• Clarify the difference between Radiation Protection and Radiation Safety (and communication to all)
• Systematic incident/accident declaration for RP/RS related aspects
