The American National Standard ANSI Z provides guidance for lasers in health care, and it is applicable to lasers that operate a. ANSI Z is recognized as the definitive document on laser safety in all health care environments. It provides guidance for the safe use of lasers for medicine. 4 days ago ZORG is the administrative website of the Accredited Standards Committee ( ASC Z) and related subcommittees. The ANSI Z

However, ANSI does not approve the content.

The Class 1 category is therefore significantly expanded for those lasers. The Control Measures section of the new standard specifically treats safety issues associated with laser pointers, and provides guidance for the safe use of these products. The Z standards are revised after an extensive review process is completed to ensure that all information is correct and up-to-date. With advances in laser device technology driving new designs, the new laser pointers generally contain a diode laser that is classified as Class 3a.

We have no amendments or corrections for this standard. This clearly produced a conservative approach to the hazard evaluation for such sources. If you are just now beginning your journey as a Laser Safety Officer, the Z standards are a great tool to have while you complete the necessary training and develop your laser safety program.

This newly revised standard will contain several important additions and changes to the last ANSI Z With the emergence of new biological data for sub-nanosecond pulses, more precise and less conservative guidance is provided in the new standard for ultrashort pulses down to femtoseconds in the retinal hazard region of 0.

Most current Class 2 will remain Class 2 or will become 2M if they possess a highly divergent beam.

The new standard also facilitates the methodology of dealing with small and extended sources. CopyrightLaser Institute of America.

There are a number of additional Z laser safety standards available that cater to a variety of industries and professionals, not just those that use laser technology outdoors, ajsi Maximum Permissible Exposures MPEs The new standard revises the tables containing MPEs, and methods by which hazard evaluation and laser classifications are done for ocular exposure of small intrabeam viewing and extended source viewing.


It provides guidance for the safe use of lasers for medicine, diagnostic, cosmetic, preventative and therapeutic applications in any location where bodily structure or function is altered or symptoms are relieved. Lasers used in these applications are incorporated into an apparatus referred to as a health care laser system HCLSwhich includes a delivery system, a power supply, mechanical housing and associated liquids and gases as required for operation of the laser.

Control measures ans one anso of practice do not ajsi apply to the other. The biological data thus produced provides the basis for extending the formalism and hazard limits into new parameter space. Having the laser safety standard most applicable to your profession is essential to maintaining a successful laser safety program.

New Revision of ANSI Z (Laser Safety Standards)

There are a number of additional Z laser safety standards available that cater to a variety of industries and professionals, not just those that use laser technology outdoors, including:. For wnsi shorter than 10 —9 seconds, the guidance was to z1366 the MPE for 1 ns. Once a subcommittee has completed a standard, the other committees review the document — a process that can take several years. In the past several years the use of laser pointers has proliferated significantly.

This should be contrasted with previous generations of laser pointers that were based on HeNe lasers and were generally classified as Class 2.

The photonics industry is ever-changing, and LIA is dedicated to helping LIA members and non-members alike get the resources they need to ensure their laser safety programs are safe and up-to-date. Thesestandards provide protocols and procedures you can use to create a laser safety program in a ansl that may not have had one before.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

In the absence of accepted biological data, the previous standard only provided MPE data for pulses down to 10 —9 seconds, or one nanosecond ns. Flashblindness, afterimage, and glare can occur as a result of exposure to laser pointers and may result in visual dysfunction that can affect visual-critical activity such as driving or flying.

Because laser safety measures are different for each industry, control measures for one industry can be very different from another.


As more and more workplaces in the United States begin to implement laser technology, the need to stay on the leading edge of laser safety updates becomes more important. Class 3R for reduced requirements is for laser products that are marginally safe for intrabeam viewing.

Class 1M is composed of lasers, which are incapable of causing eye damage except when viewed with optical instruments. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

New Revision of ANSI Z136.1 (Laser Safety Standards)

Thus in the visible part of the spectrum, Class 2 range is 0. If the document is revised or amended, you will be notified by email. The new hazard signs contain an equilateral triangle attention symbol in addition to the familiar sunburst pattern. The revision expands upon the previous version and hopes to meet the evolving needs of outdoor laser operators. The appendix contains numerous examples that illustrate and clarify the application of the new methodology.

Before publishing, the American National Standards Institute approves the document. Your Alert Profile lists the documents that will be monitored. And since the Laser Institute of America LIA serves as the publisher of the series, you can be confident that you are purchasing the most current laser safety information available.

If you have purchased one of the Z standards in the past, LIA will send you an email notification when the standard is revised — allowing you to stay on the forefront of new laser safety information.

Subscription pricing is determined by: The great proliferation of these devices has made it more likely that individuals who are not familiar with appropriate safety precautions would use them. To help rectify the situation, the IEC is considering slight modification to their classification scheme that would more clearly define risk levels under reasonably foreseeable use.

Three new classes of lasers are being created 1M, 2M and 3R.
