The ANSI Z136.9 - Hardcopy Version provides reasonable and adequate guidance for the safe use of lasers and laser systems that operate at wavelengths between 180 nm and 1 mm.

Z136.9 is intended to protect individuals with the potential for laser exposure when lasers are used in manufacturing environments, this standard includes policies and procedures to ensure laser safety in both public and private industries as well as product development along with testing.

The new standard comes at a critical time, as lasers continue to populate more processing lines in the aerospace, automotive, energy, defense, and healthcare industries.
