       17 GRABRAILS
       Grabrails shall comply with the following:
       (a)    Grabrails shall be not less than 30 mm and not more than 40 mm outside
              diameter; or they shall have a sectional shape within the limits of 30 mm to
              40 mm diameter.
       (b)    Exposed edges and corners of grabrails shall have a radius of not less than
              5 mm.
       (c)    The fastenings and the materials and construction of grabrails shall be able to
              withstand a force of 1100 N applied at any position and in any direction
              without deformation or loosening or rotation of the fastenings or fittings.
       (d)    The clearance between a grabrail and the adjacent wall surface or other
              obstruction shall be not less than 50 mm and not more than 60 mm. The
              clearance above a horizontal grabrail shall extend above the top of the
              grabrail by not less than 600 mm. The clearance below a horizontal or angled
              rail shall be a minimum of 50 mm except at fixing points.
       (e)    Grabrails shall be fixed so that there is no obstruction to the passage of the
              hand along the top 270° arc of horizontal and angled grabrails. There shall be
              no obstruction to the passage of the hand for the full length of vertical
              grabrails.

       18.1 Wheelchair seating spaces
       Where fixed seating is provided, wheelchair seating space shall be as follows:
       (a)    Adjacent to, and on the same level as, other seating in the row and shall be
              accessed by a continuous accessible path of travel.
       (b)    Located to allow lines of sight comparable to those for general viewing areas
              and shall not be obstructed by opaque handrails or balustrades.
         NOTE: Wheelchair seating spaces may be achieved by providing removable seating.
       18.2 Surfaces
       The ground or floor at wheelchair seating spaces shall be level when indoors or
       have a gradient not steeper than 1 in 40 in outdoor areas.
       18.3 Spatial requirements
       The minimum space for each wheelchair shall be as shown in Figure 54(A). The
       whole of the space allocated for any wheelchair shall not impinge on the
       dimensions required for aisles by more than 250 mm, or for crossovers by more
       than 300 mm. See Figures 54(B) and 54(C).
