There is a general recommendation that the walls in multi-sports
halls should be flush and free of any hazardous projections.
The situation should be considered against the particular
sports, levels of play to be accommodated and the size of the hall,
but the risks of contact with the side wall are likely to be
greater for fast moving ball team games such as five-a-side
football and basketball.
See separate Guidance Note on Sports Hall
Design
The walls should be flush to a height that takes into account
the height and arm reach of potential users.
Heights between 2.1 – 2.3m are often adopted so that the lining
material can run through with the heads of access/equipment store
doors and maintain a clean visual line around the hall.

Net bags above 1.2m for 5 a side
rebound

Door panelled to be flush with sports
hall wall
Doors should be detailed to be flush with the
wall or with rebound panels to avoid hazardous corners/projections.
Foam padding may be considered to add protection in some
situations. In the case of fire doors (with an integrated panic
bar) the lower rebound panel should be 1.21m high to maintain a
continuous rebound surface for five a side football but should also
be agreed with the Fire office.
Care should be taken over items of fixed sports
equipment, which are often installed by separate contractors. It
might be acceptable for soft items such as bags for netting to be
located below the likely body contact level, as long as the actual
fixing are detailed to avoid being a hazard and not lower than the
1.21 mentioned above.
Other items that need special consideration
include power sockets, fire alarm points and cleats and pulleys for
overhead spotting rigs.
