New Expanded Revision!
The parent document and cornerstone of the Z136 series of laser safety standards, the revised ANSI Z136.1 (2007) provides guidance for the safe use of lasers and laser systems by defining control measures for each of the four laser classes.

As a result of advances in laser devices and applications, new guidelines have been incorporated into this 2007 revision. The new revision should be obtained by all laser end users and is a must for users of class 3B and 4 lasers as it renders all previous editions obsolete. Since the ANSI Z136.1 standard is the foundation of laser safety programs for industrial, military, medical, and educational applications nationwide, revisions to the previous version can and will affect the training and practice of laser safety in these environments. Changes to the previous version include the addition of new laser hazard classification definitions, new requirements for refresher training, and changes to medical surveillance requirements. The ANSI Z136.1 (2007) standard provides an updated and thorough set of guidelines for implementing a safe laser program.

In addition to these changes, the standard covers laser safety program provisions including the duties and responsibilities of the LSO, non-beam hazards, administrative/engineering control measures, definitions, optical density, nominal hazard zone (NHZ), MPEs, accessible emission limit (AEL), bioeffects, standard operating procedures (SOPs), and example calculations.

ANSI Z136.7 (2008) for Testing and Labeling of Laser Protective Equipment

File Size: 1MB-PDF Format

NEW in 2008! The objective of this standard is to provide reasonable and adequate guidance on the test methods, protocols and specifications for devices used to provide eye protection from lasers and laser systems. Testing procedures are provided in this document to ensure that eyewear, windows, and barriers maintain their specified level of protection throughout the life of the products.

Such protective devices include laser eye protective devices or instrument filters, laser window filters, and laser area protective barriers, screens or beam blocking curtains. Depending on the protective device, laser type, temporal mode of operation and wavelength(s), different test methods may be required. (PDF Format, 60 pgs.)

The recommended stepwise procedure for using this standard is as follows:

• Determine the type of protective equipment (device); eyewear, barrier, or window.
• Determine the filter technology used; absorptive, reflective, or hybrid.
• Determine the material type of eyewear/windows under study: material, metal, plastic, glass, hybrid, etc.
• Determine the appropriate laser or laser system: continuous wave, Q switched, or sub-nanosecond, or some combination of pulse durations.
• Determine the wavelength or wavelength band of the laser protection.
• Determine the specified optical density or barrier threshold level as identified by the manufacturer at the wavelength in question.
