General Announcement:

- Q&A session with SRP/Tobias Haas:
1. External companies have to provide self-assessment to show they have measures in place that comply with EuXFEL regulations on safety related to Covid-19. 
The EuXFEL online training is installed at the gate house and the companies have to make the Covid-19 training. EuXFEL groups have to inform the external companies.
Slides of the training will be provided to the groups for being send to the external companies.
2. One has to observe the maximum occupancy of each room and follow the EuXFEL training. If you stick to the max occupancy, you can work without masks in case minimal
distance is respected - otherwise mask is mandatory. For control hutches we admit only 2 persons. 
3. SRP finds a good idea and encourages instruments to implement additional measures for the hutches that e.g. cover use of tools, computers and/or disinfection 
procedures. 
Nevertheless, such extra local rules must not overrule the EuXFEL rules covered in the training. 
Extra regulations shall be printed and make available at doors, for example. Responsible for rooms and and hutches or local staff must make sure these additional
regulations are explained and followed. 
4. EuXFEL will not provide PPE to external companies.
5. Tobias will check with MB if EuXFEL has to provide PPE to DESY employees. In principle, EuXFEL applies the same rules as DESY.  
6. There is currently no decision on which rules apply to external visitors regarding the summer shutdown. We assume initially they will not be able to come. 
SRP encourages groups to send questions to health@xfel.eu and the Covid-19 task force will discuss the matter.  
7. There is no decision yet if the FFP-2 masks will be disposed after use or treated for re-use. Initially EuXFEL assume they will be disposed. 
It is yet unclear how long time a mask can be used before loosing efficiency. The slides presented at staff meetings contain suggestions in how to use the masks.

- General: There is no current issues to be discussed today regarding the tunnel access and related work;

- General: No issues have been pointed on the control network activities scheduled for next week. 
XPD must send to CTRL information on when a test of a shutter valve of gas supply will take place (still to be defined) in order to test the notification service.

Relaxation control network: 
- CTRL and XO remind the groups to submit the planned activities on e.g. scenes, projects, until Fridays. 
- For next week case: please limit any hardware change. Reason is the current limitation on the physical presence of staff. 
Groups will support only emergency and priority tasks. From May 4th the situation will be different. 
- However, we do not want to stop any progress on activities. This also includes work on Karabo that affects critical work like VAC in tunnels.

Tunnel access for the coming weeks:
- A scheduling plan will be made due to the restrictions of allowed people working on tunnel at the same time. 
Plan will be made in order to respect safety rules and minimize number of people working in tunnels. 
- Tunnel access will be a first agenda point from next week.

General:
- For next meetings, we will continue with the small report from the support and instrument groups.
- Tasks to happen in the hutches are decided by the groups. XO/PMO plan tasks in tunnels.
- We encourage groups to start as earlier as May 4th the tasks which were originally planned to be conducted during the summer shutdown. 
If it needs tunnel access, then one must respect the coming schedule.
- XO is looking together with Desy on all tunnel activities. A schedule is being prepared and will be communicated to the groups as soon as possible. 
- In case of delay of activities due to e.g. excess of people in tunnel, prioritization will be made together with XO and Desy.

General Announcement:
- An e-mail was sent yesterday about the relaxation of restrictions on the control network.
- From now on, the XO integration meeting series will happen on Monday and Wednesday at 09:30 and Friday at 11:30.
- These meetings serve two purposes: 1.exchange of information for the re-start phase, and 2. Controls issues. 
- This procedure is set to help the re-start of activities coming from the super-restricted operation mode.
- Groups are asked to send by every Friday to controls-integration@xfel.eu a summary of activities to be carried out during the following week regarding the Control 
Network. 
This helps CTRL and XO to prepare and coordinate the full scope of activities while having an overview on actions that require large scale resources.
- For example, groups and staff who move motors have to be cautious, once reduced number of people will have access to debug devices in case they get stuck.
- This process could be reviewed in the course of next weeks.
