3.4.3.7 User access
The unit should have a minimum clear area, in front of the designated working position that drawers and other extendable elements, except for pen drawers and extendable keyboard platforms, should not protrude into when open. The recommended minimum clear area should be defined by an erect semicylinder with a diameter of 700 mm, with the arc of the cylinder centred on the designated working position at the working edge. The height of the semicylinder should equal or exceed the primary work surface height of the unit (see Figure 7).
NOTE: This recommendation is intended to identify the need for adequate user access to the unit’s designated working position.
3.4.4.2 Single task work
For single task work the primary worktop shall—
(a) have 1200 mm of working edge length;
(b) have a work surface depth ³600 mm along the 1200 mm of working edge length (see Figure 8, Figure 9 and Figure 10);
NOTE: The work surface depth will need to be 700 mm deep at the designated working position to allow the template to fit on the work surface. However, either side of the designated working position the work surface depth can be as shallow as 600 mm. Of course desks with a straight rectangular worktop type will, by necessity of their design, need to have a minimum work surface depth of 700 mm to fit the template.
(c) have the designated working position located within the 1200 mm of working edge length, but shall be no less than 250 mm from either end of the 1200 mm of required working edge; and
(d) when the working edge either side of the designated working position angles away from the user (sitting/standing at the designated working position) it shall do so at no more than 25° for the remaining length of the required 1200 mm of working edge (see Figure 10).
