Safety
LIPs for installation in restrained environment (cinema theaters) shall be installed at height vertically above the
floor such that the bottom plane of the hazard distance zone shall be no lower than 2.5 meters above the floor.
Horizontal clearance to the hazard distance zone shall be not less than 1 meter.
LIPs for installations in unrestrained environment (large venues,..) shall be installed at a height vertically
above the floor such that the bottom plane of the Hazard distance Zone shall be no lower than 3 meters above
the floor. Horizontal clearance to the hazard distance zone shall be not less than 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 hazard distance zone.
In addition for temporary installations (e. g.: rental and staging, lease, events ...) the following requirements
apply:
•
This product can only be installed by Barco or sold or leased only to valid laser light show variance holders.
In other words our installers are required to have an approved laser light show variance. Such installers
may currently hold a valid variance for production of Class IIIb and IV laser light shows and/or for
incorporation of the RG3 LIPs into their shows. Dealers and distributors are also required to obtain a valid
laser light show variance.
•
This product shall be located in such a way that all propagating beam paths within the Restriction Zone,
and the audience can be directly observed at all times.
•
Effects other than front or rear screen projections shall not be performed.
•
Communication shall be maintained with other personnel assisting in surveillance of the LIP projection.
•
In the event of any unsafe condition, immediately terminates (or designate the termination) of LIP
projection light.
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 2014-V-0285.
The installation checklist for laser illuminated RG3 projectors must be fully completed after the installation and
sent to pvg@barco.com. 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.
1.6 HD for fully enclosed projection systems
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).
