B.3 Partial Restriction Zone projector side
Situation
This situation can occur if the inclination of the floor is much greater than that of the light beam. The Height (H)
between the floor and the light beam is smaller than the minimum Separation Height (SH) at the projector side
of the Hazard Distance range. This part must be fenced off as a Restriction Zone (RZ). The Restriction Zone
ends at the intersection point (white arrow) where the Height (H) equals the minimum Separation Height (SH).
The Restriction Zone must be extended laterally by the minimum Separation Width (SW). The red hatched
area in the following illustration indicates the partial Restriction Zone (RZ) towards the projector.
