and building work.

- Number of people on sites include CERN’s personnel as well as contractors.

- Personnel involved in LS2, accelerator and detector upgrades, urgent site and building work

will come back gradually as of 18th May.

- The rest of personnel will come back gradually as of 2nd week of June.

- Personnel will be called by supervisors

LS2 and Projects structures are maintained

- Using an identical scheme as for Safety coordination since have

demonstrated efficiency.

- All meetings will continue as before the partial CERN closure, remote

connection will be systematically proposed.

WITH, additional measures linked to COVID-19

- Health & Safety protection of workers according to COVID-19 directives.

- To be taken as an additional hazard managed by line management.

- LS2 Committee to indicate eligible activities which could resume.

- Based on indications by the LS2 Coordination, projects priorities and

requests from Groups and Subcontractors.

Re-start under LS2 Coordination

Phase 0: evaluating CERN readiness for re-start after Safe-mode and urgent activities

Selection of activities based on priority for the Organisation

Resume the technical services/workshops to nominal performance where needed.

Cap the number of persons permanently at CERN to 600 during Phase 0.

Limit the working places to allow best Safety follow-up: sites inspections, (mini)VICs,

logistics, etc.

Avoid whenever possible to recall personnel from Contractors before Host States

deconfinement.

Management of activities by line management in the departments in

collaboration with LS2 coordination.

Phase 1: Resume gradually. Guidelines for personnel ramping-up ~+500 every week

LS2 rules & guidelines stay valid: new activities announced at LS2C with

relevant PLAN item for validation.

QA efforts be maintained particularly configuration management, integrations, ECRs,

layout database, etc.

Resuming activities going on before going on Safe mode.

Starting new activities shall be discussed with LS2C after checks with line

management of the departments.

Set a priority list of activities needed for LS2 Stage 2 period, including all

experimental areas and projects.

Evaluation of resources from support groups to define their ramping-up schemes.

Compatibility with Groups activities, solving coactivity issues and prioritisation.

Safety first

- To respond to all safety hazards and maintain

the highest standards of safety as demonstrated

since the start of the LS2.

- COVID-19 will be addressed as an additional

hazard with all the necessary adjustments that

may be needed following feedback and

recommendations by experts and the Host States.

Frédérick Bordry

5th May 2020

CERN now has a better vision of the situation, thank you all for your contribution

to the development of this plan.

A gradual re-start is possible, providing a strict respect of the safety rules

and the sanitary measures in place by HSE and the local authorities.

We have to be patient as we are all recovering from an unexpected period and a

unique long safe-mode

Take care and don’t forget our successful slogan:

Safety first, Quality second and Schedule third

Work on the CERN sites will resumegradually. The presence on site of everymember should be limited to the timerequired to carry out the approvedactivity/ies.
