14:05 → 14:15 Safety matters

Speakers: Hanne Heylen (CERN), James Devine (CERN), Joachim Vollaire (CERN)

There was an evacuation alarm in the target area and in the hall Monday 4/5 which is likely due to dust when making some core drilling from outside the target area to make the “niche” for the new camera. A IS37 was in place to inhibit the fire detection but for some reasons it was not in force and effective.

Some of the users present in the hall went to b. 508 instead of the assembly point.

Reminder to :

1. If the evacuation alarm sounds or if instructed to do so by an Emergency Guide, leave the building using the nearest and safest exit route.
2. Walk quickly and calmly to the designated assembly area.
3. Remain at the assembly area  until instructed to leave by the TSO or Fire and Rescue Service personnel.
4. Do not re-enter the building until informed that it is safe to do so by the TSO or Fire and Rescue Service personnel.

AOB

• Route einstein next to b. 133 - circulation alternee 11/05- 22/05
• Intervention to turn sector valve where ISOLDE ends and COLLAPS start next to COLLAPS before installation of pilar for RILIS (before end of June) -> agree on moment (not at moment where a visit is planned)
• Should we add MEDICIS back into the agenda of the meeting now operations have restarted? Especially when restriction is over at the end of the month.
