ANSI Z136.2 – American National Standard for Safe Use of Optical Fiber Communications Systems Utilizing Laser Diode and LED Sources (1997)
This standard provides guidance for the safe use, maintenance and service of optical fiber communications systems (OFCS) utilizing laser diodes or light emitting diodes (LED) operating at wavelengths between 0.4 µm and 2.6 µm. This standard applies only to systems where the radiant energy is confined within an optical fiber during intended use.Note: This standard has been withdrawn, pending the issue of the next revision in 2010-2011

ANSI Z136.3 – American National Standard for Safe Use of Lasers in Health Care Facilities (2005)
This standard provides guidance for the safe use of lasers for diagnostic, cosmetic, preventive, and therapeutic applications in health care facilities (HCF). For the purpose of this standard, health care facility is defined as any location where a laser is applied to humans for diagnosis of disease, or for preventive, cosmetic or therapeutic purposes, where bodily structure or function is altered or symptoms are relieved.

ANSI Z136.4 – American National Standard Recommended Practice for Laser Safety Measurements for Hazard Evaluation (2005)
This recommended practice provides adequate, practical guidance for necessary measurement procedures used for classification and hazard evaluation of lasers. The information provided in this recommended practice is intended to assist users who are entrusted with the responsibility of conducting laser hazard evaluations to ensure that appropriate control measures are implemented.

ANSI Z136.5 – American National Standard for Safe Use of Lasers in Educational Institutions (2009)
This standard applies the requirements of the ANSI Z136.1 for Safe Use of Lasers to the unique environments associated with educational institutions. Such settings include teaching laboratories, classrooms, lecture halls, science fairs, and science museums, which have incorporated lasers into their educational process. It is intended for staff and students using lasers for academic instruction in university, college, secondary, or primary educational facilities.

The ANSI Z136.5 specifically provides laser safety guidance by evaluating and minimizing hazards associated with laser radiation in educational settings at all levels. It also discusses developing laser safety programs and student training. Various diagrams and examples of properly placed lasers and laser systems in relation to the audience are included.

ANSI Z136.6 – American National Standard for Safe Use of Lasers Outdoors (2005)
This standard provides guidance for the safe use of lasers in an outdoor environment. It covers product performance of lasers used outdoors including those that have been granted a variance or exemption from the provisions of the Federal product performance standard (21 CFR 1040). Products and applications covered:

* Laser Light Shows
* Military Lasers
* Lasers used for outdoor scientific research
* Wireless optical communications systems deployed outdoors

The standard also covers possible indirect hazards such as visual interference at night to pilots during take-off and landing.

ANSI Z136.7 – American National Standard for Testing and Labeling of Laser Protective Equipment (2007)
The objective of this standard is to provide reasonable and adequate guidance on the test methods, protocols and specifications for devices used to provide eye protection from lasers and laser systems.

Z136 standards and recommended practices are developed through a consensus standards development process approved by the American National Standards Institute. The process brings together volunteers representing varied viewpoints and interests to achieve consensus on laser safety related issues. As secretariat to ASC Z136, the Laser Institute of America (LIA) administers the process and provides financial and clerical support to the committee.
