Rows of common singing must have an impulse ventilation (ideally cross ventilation) of at least 15 minutes.
– Continuous external ventilation (e.g. windows on tilt or fully open) should be provided from the beginning of the rehearsal or the event to the end.
After the end of a rehearsal in which 60 minutes of singing have taken place, the room must be ventilated crosswise for 30 minutes, after which the room must remain empty for two hours. Before the start of the next rehearsal, again, cross-ventilate for 30 minutes.
