1.4 Risk Group 3 Safety
1.4.1 General considerations
Notice on optical radiation from F80 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 or several built-in Class 4 laser clusters. Disassembly or modification is very
dangerous and should never be attempted.
•
Any operation or adjustment not specifically instructed by the user's guide creates the risk of hazardous
laser radiation exposure.
•
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.
WARNING: No direct exposure to the beam within the hazard distance shall be permitted, RG3
(Risk Group 3) IEC EN 62471-5:2015
CAUTION: Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
PPE (Personal Protective Equipment) description.
A skilled person or service person shall be worn protective clothes and goggles when access to restricted
area.
Possible skin or eye damage.
Disconnect power before servicing.
1.4.2 High Brightness precautions: Hazard Distance (HD)
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 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
To protect untrained end users (as cinema visitors) the installation shall comply with the following installation
requirements: Operators shall control access to the beam within the hazard distance or install the product at
the height that will prevent spectators' eyes from being in the hazard distance. Radiation levels in excess of
the limits will not be permitted at any point less than 2.0 meter (SH) above any surface upon which persons
other than operators, performers, or employees are permitted to stand or less than 1.0 meter (SH) lateral
separation from any place where such persons are permitted to be. In non-cinema environments where
unrestrained behavior is reasonably foreseeable, the minimum separation height should be greater than or
equal to 3.0 meter to prevent potential exposure, for example by an individual sitting on another individual's
shoulders, within the HD.
These values are minimum values and are based on the guidance provided in IEC 62471-5:2015 section
6.6.5.
The end user must understand the risk and apply protective measures based upon the hazard distance as
indicated on the label and in the user information. Installation method, barriers, detection system or other
applicable control measure shall prevent hazardous eye access to the radiation within the hazard distance.
