This part of IEC 60825, which is a technical report, gives guidance on the planning anddesign, set-up and conduct of laser displays and shows that make use of high power lasers.The laser power needed to produce effective theatrical or artistic displays in large spacessuch as theatres, arenas, or architectural sites is great enough to pose a severe accidentalexposure hazard, even when personal exposure is very brief. For this reason, subclause 4.1.5of IEC/TR 60825-14 specifies that only laser products that are Class 1, Class 2 or visiblebeamClass 3R should be used for demonstration, display or entertainment purposes inunsupervised areas. Laser products of other classes should only be permitted under carefullycontrolled conditions and under the control of a trained experienced operator.The guidance provided in this technical report is not intended to include the display ordemonstration of scientific, medical or industrial laser products. However, many of theprinciples in this guidance may be relevant. This guidance provides recommendations forsafety for those laser displays or demonstrations that are shows, artistic displays, advertising or light sculptures, or museum pieces used to demonstrate optical principles, etc.Laser products available for use in a domestic environment or for use by people who cannotbe expected to have received a suitable level of training should be Class 1, Class 2 or visiblebeam Class 3R. Therefore, such equipment is outside the scope of this guidance.
