Application-Specific Additions
Z
A
is the additional distance needed to account for factors that can otherwise affect the safe application of the Scanner.
Examples include:
 Approach speed of an individual who is unaware of the vehicle's movement. ISO 13855 ―Positioning of
Safeguard with Respect to Approach Speed‖ defines walking speed as 1600 mm/s (63‖/s), thus Z
A
= 1600
mm/s x (T

)
 Additional clearance to avoid crushing, Z
A
= 500 mm (20") per ISO 13854 (EN349)
 The effect of turning with long vehicles or trailers, resulting in large lateral travel
Multiple factors may or may not result in a cumulative effect: Z

. Evaluate each factor to determine
its impact on all Additional Distance Factors (Z).
Additional Side Distance Z (Protective Field Width)
The width of the Protective Field is determined by the width of the mobile vehicle and the Additional Distance Factors (Z)
as described above (also see Figure 3.13 Z
LEFT
and Z
RIGHT
). The distance Z may be different for the two sides and the
leading edge. The width of the Protective Field must be greater than the width of the mobile vehicle.
