scope:

This standard provides guidance for the safe use of potentially hazardous lasers and laser systems (0.18 μm to 1 mm), in an outdoor environment. It also provides guidance for controlling disability glare from exposure to non-injurious levels of visible laser light (see Appendix H), which might interfere with sensitive or critical tasks, and guidance for the manufacturers of these open-beam laser systems. Lasers used for fixed, terrestrial point-to-point freespace optical telecommunications are not covered in this document, but will be covered in the revision of ANSI Z136.2-1997.
