Minimum Surfacing Area: 19.3m²
Minimum Free Space Required: 7.0m x 3.99m
Free Fall Height: 1.43m
Safety surface area dimensions above are for wet pour surfacing (synthetic). If loose fill is being used the length needs to be increased to 7.7m (from 6.7m) to allow an extra 500mm of surfacing at either end.
Additionally, for a wet pour impact area that is level with the surrounding surface, there must be an additional area with a length of 500mm in the direction of the swing free from obstacles.
