such that the bottom plane of the Hazard Zone shall be no lower than 3 meters above the floor. Horizontal clearance
to the hazard zone shall be 2.5 meters. Any human access horizontally to the Hazard Zone, if applicable, shall be
restricted by barriers. If human access is possible in an unsupervised environment, the horizontal or vertical
clearances shall be increased to prevent exposure to the RG3 hazard zone.

holders (laser light show manufacturers) for image projection applications. Such manufacturers may currently hold a
valid variance for production of Class 3B and 4 laser light shows and/or for incorporation of the RG3 projector into
their shows. This requirement applies also dealers and distributors of these RG3 projectors. For show installations
