Laser demonstrations, displays and exhibitions
Only Class 1 or Class 2 laser products should be used for demonstration, display or entertainment in
unsupervised areas. The use of other classes of lasers for such purposes should be permitted only when the
laser operation is under the control of an experienced, well-trained operator and/or when spectators are
prevented from exposure to levels exceeding the applicable MPE.
Each demonstration laser product used for educational purposes in schools, etc. should comply with all of the
applicable requirements for a Class 1 or Class 2 laser product. A demonstration laser product shall not permit

Class 1M, Class 2, Class 2M and Class 3R laser products
Precautions are only required to prevent continuous viewing of the direct beam; for Class 1M, Class 2 and
Class 2M, a momentary (0,25 s) exposure to radiation in the wavelength range400 nm to 700nm as would occur
in accidental viewing situations is not considered hazardous. However, the laser beam should not be
intentionally aimed at people. The use of optical viewing aids (for example, binoculars) with Class 1M, Class
2M and Class 3R laser products may Increase the ocular hazard. Additional precautions for Class 1M, Class
2M and Class 3R laser products are given in 12.6.2.
