•Tunnel access during powering – what areas can be accessed during powering as a function of current / energy in the different circuits? Clear and transparent rules •Matrix between powering and access (where not to go when?) •Document to be provided

4. How to ensure safety during powering? (ENFORCING the RULES)

•Powering phase I at low current: How to ensure that the current does not exceed the “safe” value? •Powering phase II: How can we be sure that nobody is in when we power? •Underground access during powering phase I and II for interventions: How to ensure that we do not power a circuit during such intervention (such as with the PIC)? •Underground access during commissioning of the powering...

5. Safety issues related to commissioning and operation of the powering system

•Changes in safety procedures (ADI, …)? •Recall consignation •Who does it? Gerard Pastor for commissioning? Interventions during night and weekend? •Setting hardware limits for the current of power converters during powering •Tests of UPS – working as expected?
