The appendix contains numerous examples that illustrate and clarify the application of the new methodology. 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 past several years the use of laser pointers has proliferated significantly. They are routinely used in demonstrations, alignment, educational, and numerous other applications. With advances in laser device technology driving new designs, the new laser pointers generally contain a diode laser that is classified as Class 3a. This should be contrasted with previous generations of laser pointers that were based on HeNe lasers and were generally classified as Class 2.

The great proliferation of these devices has made it more likely that individuals who are not familiar with appropriate safety precautions would use them. While it is unlikely that momentary exposure to laser pointers will cause permanent retinal damage, exposure to these devices can cause other visual impairment.

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 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 ANSI Z specifies sign dimension, lettering size, color, and other important sign design elements. The new hazard signs contain an equilateral triangle attention symbol in addition to the familiar sunburst pattern. The new triangular symbol is introduced into both the "Caution" and "Danger" signs.

Currently few differences exist between the two standards. You may delete a document from your Alert Profile at any time. This standard is also available to be included in Standards Subscriptions. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Subscription pricing is determined by: the specific standard s or collections of standards, the number of locations accessing the standards, and the number of employees that need access.

As the voice of the U. Most recent. ANSI Z Laser safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries.

Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations. The version is available for distribution as of August , per the LIA email announcements. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Subscription pricing is determined by: the specific standard s or collections of standards, the number of locations accessing the standards, and the number of employees that need access. A practical means for accomplishing this is to 1 classify lasers and laser systems according to their relative hazards and to 2 specify appropriate controls for each classification.

Once a laser or laser system is properly classified, there should be no need to carry out tedious measurements or calculations to meet the provisions of this standard. However, technical information on measurements, calculations and biological effects is also provided within the standard and its appendixes.
