Attended by ALICE, ATLAS, CMS, LARP, and LHCb members from the U.S.
This is an open meeting. We informed Aymar and Engelen who consider it a “private meeting” – no intent to criticize CERN’s excellent safety record.
The meeting is being attended by the ATLAS and CMS GLIMOS (Group Leader in Matters of Safety) Olga Beltramello and Christoph Schäfer, the ATLAS Technical Coordinator, Marzio Nessi, the heads of safety at BNL and Fermilab, Jim Tarpinian and Bill Griffing, and DOE/NSF here for the RRB.
Motivated by the recent incident in ATLAS

Subject: TR : Sector 13 Atlas
After the facts of last Thursday, we have decided to reorganize the access to the sector 13, avoiding from now on to cross the trenches.
All this was done last Friday and the CERN safety coordinators inspection took place yesterday. After few iterations and after having restored the 2 emergency exits (towards sector 1) we have received a positive answer. The last request of John is being implemented and will be ok this morning.
So from our side there are no formal reasons to prevent people to transit via this new route to the inside of the detector and to work on the barrel calorimeter front face. A new signalization has also be put in place.
If you have any doubt on this, please contact us.

Further to our visit yesterday, the Atlas meeting this morning and our subsequent visit, we note that all the modification have been carried out, except for the rails placed under the scaffolding base plats to distribute the load, once this has been done then the sector can be reopened.
We would like to bring once again your attention to the limited space for your evacuation routes; we would ask that Atlas take there responsibility for this situation and make sure that regular visits are carried out with the fire service to ensure they are aware of the situation as the work progresses.
