Entrance and lobby doors, other than those to dwellings should have viewing panels to alert people approaching a door to the presence of another person on the other side.
If a door has a single viewing panel, the minimum zone of visibility should be between 500mm and 1500mm from the floor.
If a door requires an intermediate horizontal section for strength or to accommodate door furniture, the door should have two viewing panels, one accommodating a zone of visibility between 500mm and 800mm from the floor and the other accommodating a zone of visibility between 1150mm and 1500mm from the floor (see figure 16).
COMMENTARY ON 6.4.3. This enables a person of small stature or a wheelchair user (when approaching a door) to see, and be seen by, another wheelchair user or an ambulant person approaching from the other side, while allowing the possibility of having an opaque area across the door to provide strength, or to accommodate door furniture.
NOTE 1 More than two vision panels may be provided, or may be larger than the zones of visibility, as long as the zones are accommodated within the glazing area.
NOTE 2 Vision panels may be less than the minimum size or omitted in doors to spaces that are required to be darkened for their function, e.g. cinemas and auditoria.
