Two-storey stands are still permitted. In these cases, the bottom storey in particular should be designed to be as open as possible. Adequate ventilation of the stand must be ensured; therefore it must not be closed at the sides to ensure adequate ventilation.

On the stairs going up and down, a minimum distance of 1.50 metres between people must be ensured (this means clear staircase width with approx. 3 m). Alternatively, a narrower flight of stairs can be used in a one-way system or two separate narrower stairs (with separate entrances and exits).
