Arc 2+ aC coating 17/04/2019 J.MEIGNAN

Remarks from the aC coating team A few issues maybe to mention this afternoon : We are using bikes in ARC 3+ / ARC 2-. Bikes are identified (TE-VSC-SCC) , other people are using it. Please don’t use them. We avoided to use locks but it seems to be necessary…… Some-body used our laptop that we are using to control our coating equipment, process was ongoing. Luckily no interruption of process.  Please don’t touch our equipment / laptops !!! This morning there was a short interruption [sec] in powering in ARC 2+ (lights / 220 V / 380 V). Our coating equipment stopped (QF23010). We were there and could intervene. If this was not the case, this could have created problems. Origin: Unforeseen interruption?  Testing? 17/04/2019 J.MEIGNAN

Message from EN-EL Salut David,   Hier a eu lieu la VIC pour nos travaux surface au BA3. Comme il a été convenu avec la coordination, que durant les semaines S27 à 30 nous travaillerons qu’en surface (BA3-BB3-BAE3-BAF3) afin de permettre aux autres activités de se poursuivre en souterrain. Cependant il nous a déjà été demandé de ne pas travailler dans les zones mentionnées ci-dessous. Je sais que le BA3 est sensible en terme de cohabitation, on va tacher de compiler, mais il faudrait s’assurer que tout ceci soit cadrer car si pendant ces 4 semaines je ne peux pas tirer la majorité des câbles inter-surface je serai moi aussi contraint de décaler mon planning. Bonne journée Guillaume 17/04/2019 J.MEIGNAN
