This newly revised standard will contain several important additions and changes to the last ANSI Z By following the guidelines outlined in the standards, you are protecting your anzi and satisfying OSHA requirements that state all employers must provide a safe workplace that meets a national consensus standard, in this case laser safety. Please first log in with a verified email before subscribing to alerts.

This should be contrasted with previous generations of laser pointers that were based on HeNe lasers and were generally classified as Class x136. As the voice of the U. Proceed to Checkout Continue Shopping.

If the document is revised or amended, you will be notified by email. Currently few differences exist between the two standards.

The great proliferation of these devices has made it more likely that individuals who anssi not familiar with appropriate safety precautions would use them. In health care, you would use Z This standard is also available to be included in Standards Subscriptions. Maximum Permissible Ansk 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.


Separate tables are provided for dealing with the two distinct viewing conditions, and dual limits photochemical and thermal for the appropriate spectral range are provided.

They are routinely used in demonstrations, alignment, educational, and numerous other applications. 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. The process for conducting hazard evaluation and analysis is thus greatly simplified, and would be welcome by laser safety officers and others who are charged with the responsibility of performing laser hazard evaluation and classification as part of an overall hazard analysis.

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

ANSI Z – Lasers Today

This would allow users to better prepare for eventual adoption of these changes. Thus in the visible part of the spectrum, Class 2 range is 0. The ramifications of these changes are relatively small. This tool is essential for any LSO to have on hand.

This standard is not included in any packages. Already Subscribed to this document. Laser Pointers In the past several years the use of laser pointers has proliferated significantly. 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.

Visit the LIA website at http: While it is unlikely that momentary exposure to laser pointers will cause permanent retinal damage, exposure to these devices can cause other visual impairment.

ANSI Z – American National Standard for Safe Use of Lasers in Health Care

The IEC recognizes that their current classification scheme is problematic particularly as it relates to evaluations with and without optically aided viewing. Having the laser safety standard most applicable to your znsi is essential to maintaining a successful laser safety program.


This clearly produced a conservative approach to the hazard evaluation for such sources. Z1136 current Class 2 will remain Class 2 or will become 2M if they possess a highly divergent beam.

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

Three new classes of lasers are being created 1M, 2M and 3R. The ANSI Z specifies sign dimension, lettering size, color, and other important sign design elements.

Class 1M is composed of lasers, which are incapable of causing eye damage except when viewed with optical instruments. 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. Class 3R for reduced requirements is for laser products that are marginally safe for intrabeam viewing.

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.

Because laser safety measures are different for each industry, control measures for one industry can be very different from another. Similarly Class 2M applies to visible lasers which are safe when viewed by the unaided eye for up to 0.
