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. The ramifications of these changes are relatively small. This standard is also available to be ansl in Standards Subscriptions.

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.

They are routinely used in demonstrations, alignment, educational, and numerous other applications.

Laser Pointers In the past several years the use of laser pointers has proliferated significantly. As the voice of the U. In health care, you would use Z This clearly produced a conservative approach to the hazard evaluation for such sources.

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

By following the guidelines outlined in the standards, you are protecting your employees and satisfying OSHA requirements that state all employers must provide a safe workplace that meets a national consensus standard, in this case laser safety.

Similarly Class 2M applies to visible lasers which are safe when viewed by the unaided eye for up to 0. 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. The revision expands upon the previous version and hopes to meet the evolving needs of outdoor laser operators.


The most important changes contained in the newly revised standard are described below. Thus in the visible part of the spectrum, Class 2 range is 0. This would allow users to better prepare for eventual adoption of these changes.

While it is unlikely that momentary exposure to laser pointers will cause permanent retinal damage, exposure to these devices can cause other visual impairment. 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. However, ANSI does not approve the content. We have no amendments or corrections for this standard.

The great proliferation of these asni has made it more likely that individuals who are not familiar with appropriate safety precautions would use them. This standard is not included in any packages.

Class 1M is composed of lasers, which are incapable of causing eye damage except when viewed with optical instruments. This tool is essential for any LSO to have on hand. Subscription pricing is determined by: 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.

Having the laser safety standard most applicable to your profession is essential to maintaining a successful laser safety program.

ANSI Z – Lasers Today

Because laser safety measures are different for each industry, control measures for one industry can be very different from another. Before publishing, the American National Standards Institute approves the document. Z16 should be contrasted with previous generations of laser pointers that were based on HeNe lasers and were generally classified as Class 2.


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. 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 biological data thus produced provides the basis for extending the formalism and hazard limits into new parameter space. 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: 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.

Need more than one copy? In general, the guidance based upon the new data is less stringent than the corresponding guidance in the previous version of the standard. The ANSI Z specifies sign dimension, lettering size, color, and other important sign design elements.

In the past several years the use of laser pointers has proliferated significantly. 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. Once a subcommittee has completed a standard, the other committees review the document — a process that can take several years.

This newly revised standard will contain several important additions and changes to the last ANSI Z The Class 1 category is therefore significantly anwi for those lasers.
