The laser power needed to produce effective theatrical or artistic displays in large spaces such as theaters@ arenas@ or architectural sites is great enough to pose a severe accidental exposure hazard@ for even when personnal exposure is very brief. For this reason@ subclause 12.4 of IEC 825-1 specifies that lasers that exceed Class 1 or Class 2 should not be used for display purposes except under carefully controlled conditions and under the control of a trained experienced operator. This technical report gives guidance on the planning and design@ set-up and conduct of laser displays and shows that use of high power lasers. This guidance is not intended to include the display or demonstration of scientific@ medical or industrial laser products at trade shows@ etc. This guidance provides recommendations for safety for those laser displays or demonstrations that are shows@ artistic displays or light sculptures or museum pieces used to demonstrate optical principles@ etc.
