This newly revised standard will contain several important additions and changes to the last ANSI Z Please first log in with a verified email before subscribing to alerts. Most current Class 2 will remain Class 2 or will become 2M if they possess a highly divergent beam. Skip to content Your Guide to Selecting the Right Laser Safety Standard 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.
In the past several years the use of laser pointers has proliferated significantly. Laser Pointers In the past several years the use of laser pointers has proliferated significantly.

New Revision of ANSI Z136.1 (Laser Safety Standards)
Class 1M is composed of lasers, which are incapable of causing eye damage except when viewed with optical instruments. The great proliferation of these devices has made it more likely that individuals who are not familiar with appropriate safety precautions would use them. Having the laser safety standard most applicable to your profession is essential to maintaining a successful laser safety program.
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. Before publishing, the American National Standards Institute approves the document.
ANSI Z – Lasers Today
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. 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. As the voice of the U. Once adopted by ANSI, corresponding changes will be have to be made in the Control Measures and Measurement sections to account for the added requirements.
And since the Laser Institute of America LIA serves as the publisher of the series, you can z316 confident that you are purchasing the most current laser safety information available. Your Alert Profile lists the documents that will be monitored. The Class 1 category is therefore significantly expanded for those lasers.
The revision expands upon the previous version and hopes to meet the evolving needs of outdoor laser operators. 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.
The ANSI Z specifies sign dimension, lettering size, color, and other important sign design elements. Currently few differences exist between the two standards.
Thesestandards provide protocols and procedures you can use to create a laser safety program in a facility that may not have had one before. Job shops, researchers and medical professionals want to prevent accidents. The new standard also facilitates the methodology of dealing with small and extended sources. 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.
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.
If the document is revised or amended, you will be notified by email. However, ANSI does not approve the content. This standard aansi also available to be included in Standards Subscriptions. 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.
This should be contrasted with previous generations of laser pointers that were based on HeNe lasers ani were generally classified as Class amsi. Guidance is also offered in the use of laser eyewear in conjunction with ultrashort pulses. 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 ansk.
Standards Subsctiption may be the perfect solution. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
The IEC recognizes that their current classification scheme is problematic particularly as it relates to evaluations with and without optically aided viewing.
With advances in laser device technology driving new designs, the new laser pointers generally contain amsi diode laser that is classified as Class 3a. 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.
All current Class 1 lasers will become Class 1 and Class 1M. Similarly Class 2M applies to visible lasers which are safe when viewed by the unaided eye for up to 0. Because laser safety measures aansi different for each industry, control measures for one industry can be very different from another.
