Z136.5-2020 electronic version is a single-user PDF that provides reasonable and adequate guidance for the safe use of lasers in educational environments by evaluating and minimizing hazards associated with laser radiation.

Environments characteristic of educational institutions, wherein lasers may be found, include teaching laboratories, classrooms, lecture halls, science fairs, museums, and student projects on-and-off campus. This standard is intended for faculty and students using lasers at primary, secondary, and college levels of education, excluding graduate level research laboratories that are more comprehensively addressed by ANSI Z136.8 (latest revision) and Z136.1 (latest revision). The wavelength range of interest includes the ultraviolet (UV), visible, and infrared (IR) regions of the electromagnetic spectrum; specifically, the wavelength range from 180 nanometer (nm) to 1 millimeter (mm).
