Safety of laser products. Guidance for laser displays and shows | Status: Current

1 Scope This part of IEC 60825, which is a Technical Report, gives guidance on the planning and design, set-up and conduct of laser displays and shows that make use of high power lasers emitting output between 380 nm and 780 nm. This document does not include the display or demonstration of scientific, medical or industrial laser products that can be used in an exhibition environment for example. However, several of the principles in this document could be relevant. This document provides recommendations for safety 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 cannot be expected to have received a suitable level of training are typically limited to Class 1, Class 2 or visible-beam Class 3R. Therefore, the use of such equipment is outside the scope of this document. Image projectors that were assigned a Risk Group in accordance with IEC 62471‑5[1]1 or laser illuminated luminaires employing lamps meeting the criteria of 4.4 of IEC 60825‑1:2014, are not within the scope of this document. This document contains safety criteria for the protection of the public or persons in the vicinity of laser displays in the course of their employment. This document is intended to be used by those who:

• — design, manufacture, assemble, install or operate laser products that are Class 4, Class 3B, or non-visible beam Class 3R for display and entertainment purposes;
• — operate arenas, theatres, music festivals, TV studios, planetaria, discotheques or other places where such laser products are installed and operated; or
• — are responsible for reviewing the safety of such equipment, installations or displays.

This document is a code of practice for the design, installation, operation and evaluation of the safety of laser light shows and displays, and the equipment employed in their production. This document is also intended for persons who modify laser display installations or equipment. In some countries, there are specific requirements, such as government permissions or notifications of shows, or prohibitions, such as against laser scanning of spectators.
