      • Get at least two people for that
    • Best thing, you create an inventory list like

|Device Type|Manufacturer|Model Number|Serial Number|Comment/Location|Gefährdungsbeurteilung/Manual|Last tested|

• Tip: Work from one side of the room towards the other side of the room and sort the list accordingly
• Testing: Device needs to be taken out of racks etc, so it is not somehow in touch with protective earth grounding via the rack etc
• Write a Betriebsanweisung + Gefährdungsbeurteilung per Device-Class and link it to your device. This is on top of having a manual linked to it
• Devices connected to 230…
  • … are not allowed to be used, if they are not tested or have no valid sticker anymore
  • … are not to be operated by a person, who has not studied the Betriebsanweisung/Gefährdungsbeurteilung for this device yet.
• Gefährdungsbeurteilung/Betriebsanweisung of the lab need to be updated
  • Add point, regarding the 230V rules above
  • Add point, that devices need to be regularily tested
  • Add point, where thise inventory list is to be found
