According to the FAU hygiene measures (as of April 8), a minimum distance of 1.5m should always be maintained as far as the premises allow.
In addition, masks are still mandatory, for which at least a surgical mask, but better FFP2 mask, must be worn.
Exception: The mask may be taken off when seated, if at least 1.5m distance to other persons is kept and a sufficient ventilation is provided.
Further information and the latest regulations can be found on the FAU corona info page.
The (lab) workstations at the chair may be used again without prior reservation if these rules are observed.
If there are individual or general restrictions that make attendance impossible, the responsible lecturer/supervisor should be contacted.
