9. RISK GROUP 3 SAFETY
9.1 General considerations
Notice on optical radiation from Balder Projector when it becomes Risk Group 3.
• For RG3, no direct exposure to the beam shall be permitted.
For RG3, operators shall control access to the beam within the hazard distance or install the product at a height that will prevent
eye exposure within the hazard distance.
• This projector has one (1) built-in Class 4 laser clusters. Disassembly or modi fi cation is very dangerous and should never be
attempted.
• Any operation or adjustment not speci fi cally instructed by the user’s guide creates the risk of hazardous laser radiation expo-
sure.
• Do not open or disassemble the projector as this may cause damage by the exposure of laser radiation.
FOR PROFESSIONAL USE ONLY means installation can only be carried out by Barco AUTHORIZED PERSONNEL familiar with
potential hazards associated with high intensity light beams.
9.2 Safety Training provided by the installer
Refer to document 601–0462 “Declaration of user safety training” for training tick off and signing.
W
ARNING
:
The installer is responsible that the user is instructed. The user will sign a document to con fi rm
that the instructions have been received and understood.
Users de fi nition
The Balder projector is intended for persons who have been instructed and trained by Barco authorized personnel to identify energy
sources that may cause injury and to take precautions to avoid unintentional contact with or exposure to those energy sources.
This personnel must instruct the user about:
•
High intensity light beam. The user must respect the exclusion zone, based on the light beam Hazard Distance (HD).
• Dangerous energy sources inside the projector. The user is not allowed to remove any cover from the projector.
• The installation, maintenance or service is for skilled persons only.
• The requirements for a restricted access location and an exclusion zone .
Restricted access location
To protect untrained persons and children, the projector must be installed in a restricted access location . The de fi nition of a
restricted access location is a location for equipment where both of the following paragraphs apply:
• Access can only be gained by Barco authorized personnel or persons who have been instructed and trained by a skilled person.
The persons must have been instructed about the reasons for the restriction applied to the location and about the precautions
that shall be taken.
• Access is only possible through the use of the tool or lock and key, or other means of security like suf fi cient clearance height
(ref Hazard Distances chapter), and is controlled by the authority responsible for the location.
Why a restricted access location: This is a RG3 product. Based on international 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 optional barriers. Within the restricted area operator training is considered
suf fi cient. The applicable separation heights are discussed in "High Brightness Precautions", page 51
9.3 High Brightness Precautions
Restriction Zone (RZ) based on the HD (Hazard Distance).
The HD depends on the amount of lumens produced by the projector and the type of lens installed. See next chapter"HD in function
of the lens Throw Ratio (TR)", page 8 .
