Based on national requirements, no person is allowed to enter the projected beam within the zone between the projection lens and
the related hazard distance (HD). This shall be physically impossible by creating suf
fi
cient separation height or by placing barriers.
The minimum separation height takes into account the surface upon which persons are assumed to stand.
On image 1-1 a typical setup is displayed. It must be veri
fi
ed by the installer if these minimum requirements are met. If required a
restricted zone (RZ) in the theater must be established. This can be done by using physical barrier, like a red rope as illustrated in
image 1-2.
