The parent document and cornerstone of the Z136 series of laser safety standards, the ANSI Z136.1 is the foundation of laser safety programs for industrial, military, medical and educational applications nationwide. Appropriately, the LIA recommends this parent document to be used in conjunction with all other standards in the Z136 series for Safe Use of Lasers. ANSI Z136.1 provides complete information on laser classifications, hazard analysis and control measures needed for the development of comprehensive laser program.
