Figure 6: This spray head location is more than 1.5m from the wall to its left and is therefore not a Preferred
Position in this sense. If we assume a bookcase may be placed to the left of the head, a large shadow will result. A
second spray head would be required to complete the coverage.
For simplicity, if a Preferred Position prevents the introduction of obstructions within 3m to the left or to
the right, the spray pattern can be assumed to be free from such unknown potential obstructions in that
direction for the full 6m spray radius, as no obstruction is likely to subtend a large angle at this distance.
See for example
9. This principle applies only to unknown, potential obstructions. Known
obstructions should be treated as creating simple shadows as per page 12.
