Install one or more readily accessible controls to immediately terminate LIP projection light. The power input at
the projector side is considered as a reliable disconnect device. When required to switch off the projector,
disconnect the power cord at the projector side. In case the power input at the projector side is not accessible
(e. g. truss mount), the socket outlet supplying the projector shall be installed nearby the projector and be
easily accessible, or a readily accessible general disconnect device shall be incorporated in the fixed wiring.
Laser light shows can be requested via the FDA online eSubmitter portal or via FDA Form FDA Form 3147
referencing to Barco
’
s variance approval xxxx-xx-xxx.
The installation checklist for laser illuminated RG3 projectors must be fully completed after the installation and
sent to [email protected]. This checklist can be downloaded from the Barco website. Only when the installer is
a valid laser light show variance holder the checklist should not be sent to Barco.
12.4 Hazard Distance for fully closed projection
system
HD
Hazard Distance (HD) is the distance measured from the projection lens at which the intensity or the
energy per surface unit becomes lower than the applicable exposure limit on the cornea or on the
skin. The light beam is considered (to be) unsafe for exposure if the distance from a person to the
light source is less than the HD.
Restriction Zone RZ Based on the HD
The projector is also suitable for rear projection applications; projecting a beam onto a defuse coated
projection screen. As displayed in image 1-3 two areas should be considered: the restricted enclosed
projection area (RA) and the observation area (TH).

For this type of setup 3 different HD shall be considered:
•
HD as discussed in "High Brightness precautions: Hazard Distance (HD)", page 6 , relevant for intrabeam
exposure.
•
HDreflection : the distance that has to be kept restrictive related to the reflected light from the rear
projection screen.
