Definition: Works Any temporary or mobile activity in the fields of building or civil engineering, such as excavation, earthworks, construction, assembly and dismantling of prefabricated components, fitting out and furnishing, conversion, renovation, repair, dismantling, demolition, maintenance, upkeep (painting, cleaning), sanitation, etc. Construction/demolition of a building , Installation of buried pipelines, Replacement/renovation of lifts, Dismantling of installations, Installation of new equipment, Transformation/renovation of premises and/or sanitary facilities…

Definition: Services Any activity for which an operating entity provides CERN with know-how or skills in a specific and defined domain, such as maintenance, transport, IT or telephone support, catering, inspection or assistance, and that is the subject of a contract, a concession or another form of agreement. Service provision: Restaurants, Site Security, Mail services, Cleaning services, Transport and Handling, Upkeep of green areas, etc… Support to operational activities: Workshop (B100), Surface treatment (B102), FSU, etc…, Maintenance Activities: Lighting, Ventilation, Heating systems, Overhead cranes, Lifts, Detection systems, Cryogenic equipment, Electrical installations, etc…

Regulatory context of CERN CERN is an international organisation CERN's domain is on the FR and CH territories Staff are under the exclusive authority of the DG CERN can edit its own rules and, if not, apply the law of their host-states. According to their contract, contractors are subject to : the CERN rules, and, French or/and Swiss laws.

Safety Coordination CERN is responsible for its domain, CERN shall manage Safety on its domain, CERN shall manage Safety related to work and services on its domain, CERN shall coordinate operations and the stakeholders involved. Nb: Contractors = 2nd largest population in number after Users Accidents in greater numbers and more serious

Notions of Safety Coordination CERN Identify and communicate to stakeholders (external companies) specific risks to its business that could have an impact on the health and safety of their staff. Stakeholders (external companies or others) Identify their risks and possible interferences with CERN activities, facilities and equipment.

Category 1 Operations All the works and services executed towards the same objective: of a total volume greater than 4000 hours; and on a single, cordoned-off worksite; and involving several operating entities and not interfering with CERN’s operations.

Category 2 Operations All the works and services executed towards the same objective that are not Category 1 operations, including in particular: all works of a total volume of less than 4000 hours, or involving a single operating entity, regardless of the volume of activity; activities of any duration relating to services and concessions. Principle for Safety Coordination (traceability) Group Leader / CERN Contract Manager / CERN Work Supervisor and, Case 1: Framework Contract “Generic“ PP + initial VIC + Impacts/Specific VICs + follow-up meetings + inspections + annual update Case 2: “One-off” Operation (several interventions together) Simplified PP + VIC + Impacts + inspections/monitoring meetings Or IMPACT + VIC (if contractors already under “generic” PP + inspections/monitoring meetings Case 3: “One-off” Intervention IMPACT + VIC + follow-up inspections

Technical Stops A scheduled shutdown for preventive or corrective maintenance or for performance upgrades of the Complexes. Examples: TS, YETS, LS… Principle for Safety Coordination* Organic unit responsible for the coordination of the shutdown and, 1 Support Team assisting for Safety of the shutdown Definition of the perimeter of the operation, Planning/organisation, 1 WSCP for the shutdown (written by the Safety support team), 1 Safety document « assessment » by intervening entity, Safety associated to various meetings (planning, WPA,…), Prior declaration for each intervention (IMPACT) VIC if requested/needed - driven and minutes written by the work supervisor * Provisions not applicable to a category 1 operation, even if it is done within the framework of a technical stop.

Declaration of interventions IMPACT Inform Grab the attention Elicit comments Allow

Declaration of interventions IMPACT WHEN Interventions in complex (accelerator and experiments) Furthermore, occasionally if attention is required, for example: intervention of several companies provided in the same area, excavation, demolition and dismantling, use of scaffolding, interventions at height, work on fragile roofs, risk of electric contacts or with fluids under pressure, risks of radiation exposure, fire risks, use of gas or chemicals, Or any other status of risks or constraints for the neighborhood.

Role of the TSO Works in your building/area ? You should be informed and... ACCEPT / BLOCK / REFUSE impacts, with comments if necessary INFORM of existing risks in your building / area PARTICIPATE in visits before the work/worksite (VIC) ENSURE the conservation of the Safety level of your building / area before, during and after the work STOP any activity that seems dangerous and CONTACT the supervisor COMMUNICATE with occupants of your building / area You are not the work supervisor !!

WORKS AND SERVICES & SAFETY COORDINATION PRACTICAL CASE TSO at CERN – Works and Services – EDMS 1690571

Practical case In the following works situation, try to answer the following questions. Of what should I be careful? Before and during the activity. What information should I send and to whom? Before and during the activity. What should be my attitude depending on situations encountered during the activity? What are my contacts when needed? What further action after the work?

Replacement / Retrofit of a lift (eg. B892) Practical case Replacement / Retrofit of a lift (eg. B892) The work is done in several steps: 1. Dismantling of the existing lift This is to disassemble the cabin, all supplies (electrical and hydraulic), guides, machinery and doors. This activity is entrusted to a specialised company. Forecast: 2 lift manufacturers for 2 weeks. 2. Civil Works The bottom of the shaft must be excavated down to an additional level. The elevator doors with new dimensions, rebuilding thresholds for each level (including the floor) is also provided in this step. Core drilling will become necessary in the room Machinery (on top of the shaft). Forecast: 3 masons for 3 weeks. 3. Installation of new lift It consists in mounting the new equipment to match the equivalent of what was previously removed. Forecast : 2 lift manufacturers for 3 weeks

Practical case ELEMENTS OF ANSWERS Before the works I have to be informed (IMPACT ...), I have to know the situation where work will be done. Upon receipt of the IMPACT I have to share my observations (e.g.: apply for joint inspection) and give my consent. I have to participate in joint inspection (VIC) to inform the supervisor of the work and of any existing safety support, about risks / existing specificities in my area. I have to integrate the parameters of the work and take steps to preserve the building's safety. I have to manage aspects of communication with the occupants of the buildings (organisation, nuisance, ...) During the works I have to follow the developments of the situation where the works are ongoing and report any problems to the work supervisor first, then the Safety Support or the HSE Unit if appropriate. Specifically, I have to stop all situations of serious and imminent hazard. After the works I have to check the area after work, including the following: Construction waste evacuated Passageways and emergency exits are free from obstacles ... Area with risks of falling (false floors, doors, opening various ...) Temporary signage removed, Usual signs and emergency aids in their original place, Restarting the disabled alarm systems (according to IS37) ... And I have to be ready to initiate the safety reception (in accordance with IS4). Throughout the activity, my interlocutor is the supervisor of the work.
