R5906113 UDX 07/07/2017 111. Safety1.4 High Brightness precautions: Hazard Distance (HD)HDHazard Distance (HD) is the distance measured from the projection lens at which the intensity or the energy per surfaceunit becomes lower than the applicable exposure limit on the cornea or on the skin. The light beam is considered (tobe) unsafe for exposure if the distance from a person to the light source is less than the HD.Restriction Zone (RZ) based on the HDThe HD depends on the amount of lumens produced by the projector and the type of lens installed. See next chapter"HD in functionof modifying optics", page 14.To protect untrained end users (as cinema visitors, spectators) the installation shall comply with the following installation require-ments: Operators shall control access to the beam within the hazard distance or install the product at the height that will preventspectators’ eyes from being in the hazard distance. Radiation levels in excess of the limits will not be permitted at any point less than2.0 meter (SH) above any surface upon which persons other than operators, performers, or employees are permitted to stand or lessthan 1.0 meter (SH) lateral separation from any place where such persons are permitted to be. In environments where unrestrainedbehavior is reasonably foreseeable, the minimum separation height should be greater than or equal to 3.0 meter to prevent potentialexposure, 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 installer must understand the risk and apply protective measures based upon the hazard distance as indicated on the label andin the user information. Installation method, separation height, barriers, detection system or other applicable control measure shallprevent hazardous eye access to the radiation within the hazard distance.For example, projectors that have a HD greater than 1 m and emit light into an uncontrolled area where persons may be presentshould be positioned in accordance with “the fixed projector installation” parameters, resulting in a HD that does not extend intothe audience area unless the beam is at least 2.0 meter above the floor level. In environments where unrestrained behavior isreasonably 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. Sufficiently large separation height may beachieved by mounting the image projector on the ceiling or through the use of physical barriers.For LIPs (Laser Illuminated Projectors) installed in the USA market the above limits do not apply. Lip’s for installations other than incinema theaters shall be installed at a height vertically above the floor such that the bottom plane of the Hazard Zone shall be nolower than 3 meters above the floor. Horizontal clearance to the hazard zone shall be 2.5 meters. Any human access horizontallyto the Hazard Zone, if applicable, shall be restricted by barriers. If human access is possible in an unsupervised environment, thehorizontal or vertical clearances shall be increased to prevent exposure to the RG3 hazard 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 wordsour installers are required to have an approved laser light show variance. Such installers may currently hold a valid variancefor production of Class IIIb and IV laser light shows and/or for incorporation of the RG3 LIPs into their shows. Dealers anddistributors 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 canbe 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 sideis considered as a reliable disconnect device. When required to switch off the projector, disconnect the power cord at the projectorside. In case the power input at the projector side is not accessible (e.g. truss mount), the socket outlet supplying the projector shallbe installed nearby the projector and be easily accessible, or a readily accessible general disconnect device shall be incorporatedin 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’svariance approval 2016-V-0144.
