In order to protect the health of BTU members and guests, all possibilities for holding events such as conferences, meetings, project meetings, etc. online should be exhausted. Should this not be possible after inspection by those responsible at BTU, it is possible to register events on BTU premises, provided that the necessary protective and hygienic measures are observed. In addition to the usual documents required for event registration, those responsible must also enclose a hygiene and safety concept which also takes into account the regulations of BTU's currently valid corona operating status. When conducting the event, the provisions of BTU's corona operating guidelines, in particular the documentation requirements, must be observed.
