Risk Group 3 Safety
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
sufficient separation height or by placing barriers. The minimum separation height takes into account the
surface upon which persons other than operator, performers or employees are permitted to stand.
On image 1-2 a typical setup is displayed. It must be verified 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.
The restricted area sticker can be replaced by a sticker with only the symbol.

USA market
For LIPs (Laser Illuminated Projectors) installed in the USA market other restriction zone conditions apply.
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.
