Stand Construction / Structural Measures
Additionally for Halls 1. 6. 7a. 8a and 8b:
• Areas enclosed on all sides shall not be permissible for people to stay in as a mat- ter of principle. This also applies to the tensioned fabric ceilings fit for sprinkler in- stallation. Excluded are rooms which are only en- tered by a limited group of people, individ- ually and only for a short length of time, such as storage or utility rooms, un- manned cloakrooms, rooms with lockers, for example. • All areas (meeting rooms, office rooms, ground floors in multi-storey stands, etc.) are only permissible in an open layout in order to integrate them into the ventilation. Here a complete air exchange is to be achieved. In structural terms this objective is achieved if the values stated in the follow- ing table are implemented taking account of the maximum construction heights per- mitted:
Free opening to the aisle [m²] per 1 m front length
Depth of roof- ing [m]
Required ceil- ing height [m]

20 7 TAB: one-sided ventilation acc. to ASR A3.6 Lüftung (Technical Rules for Workplaces, Ventilation). Room occupancy acc. to SBauVO (Special Construction Ordinance). 8.0 Areas that do not fulfil these requirements and where a complete air exchange is not achieved must be alternatively equipped with a compact air filter system guarantee- ing HEPA-filter efficiency (H13 or H14) or fresh air supply must be ensured subject to technical feasibility. Fans and filterless air ventilation systems are not sufficient. Ap- proved filter systems can be obtained via the OOS. • Exhibition areas have to be designed in such a way that at least 30% of them are accessible. Deviating, event-specific regu- lations are possible. These can be found in the stand construction portal under "Spe- cifics" of the corresponding event.
All halls (excluding Hall 7.0 – 7.2):
Free opening to the aisle [m²] per 1 m front length
Depth of roof- ing [m]
Required ceil- ing height [m]

There is no requirement for maximum numbers of people on stands. The decisive factor is that the persons present can maintain a minimum distance of 1.5 m from each other. Depending on the 7-day incidence, the hygiene distances in groups may be undercut, taking into account the contact limits. In addition, hygiene distanc- es can be reduced by separations such as walls. The installation of distance markings in highly frequented areas of the stand is recommended.

• Catering at the stands depends on the current incidence level at runtime. As a matter of principle, the operators of gas- tronomy and catering services must draw up their own hygiene and infection protec- tion concept based on the CoronaSchVO and its annexes. They are responsible for the content and ensure implementation on their own responsibility.
