## Slide 1

## Vision

**Revision to a well-established and well-recognized standard**
**Build on the strengths of the document**
**Focus on improving usability and consistency**
**Update technical considerations**
**Clarify topics of hazard classification, FAA coordination, visual interference zones, etc.**
**Add definitions and index, and revise examples**

***ANSI Z136.6 Revision***

## Changes

**Single Column Format & Index**
**ANSI Z136 new Standard Practice**
**Improves Readability and Searchability**
**Definition of “Control Measure”**
**Brings Consistency of Understanding**
**Allows Explanation of Preferred Risk Mitigation Elements**
**Photopic Luminous Efficiency Function**
**Correction Factor to Visual Interference Level (VIL), rather than to Actual Exposure**
**Brings Consistency to Safety Distance Methodology**

***ANSI Z136.6 Revision***

## Changes    (continued)

**Visual Interference Zones around Airports**
**Adding Text Definitions for these Zones**
**Standardizing Units**
**Wavelengths all in nm**
**All Units in Metric**
**SAE Units Provided When Helpful**
**“****6.2 miles” now “10 km (6.2 miles)”**
**FAA Coordination Requirements Clarified**
**FAA Approval REQUIRED for 21 CFR 1040 Variances**
**FAA Contact SUGGESTED for Outdoor Use of Military Exempt Lasers or Lasers Compliant with 21 CFR 1040 **
**Most R&D, Military, Astronomy Lasers, for example**

***ANSI Z136.6 Revision***

## Changes    (continued)

**Visual Interference Zones (general)**
**Allows Designation Related to Critical Tasks, not just Airspace Considerations**
**Treats as Generic Terms - Based on Associated Visual Interference Levels**
**When Considering Navigable Airspace, “Flight” Added to Term (e.g., “Critical Zone” Becomes “Critical Flight Zone”)**
**Philosophical Change to Term “Personnel”**
**“****Personnel” Defined as Employees**
**“****People” Used for General Term**
**Figures Updated**

***ANSI Z136.6 Revision***

## Changes    (continued)

**Laser Hazard Classification**
**Practical explanation Hazard Classes**
**Refers to ANSI Z136.1 for Definitions of Classes**
**Explains Purpose of Hazard Classification**
**Application of Common Control Measures**
**Added Classification Comparison Table**
**ANSI Z136.1-2000  verses  ANSI Z136.1-2007**
**Allows Engineering Design to be Used to Determine Class**
**Operator Controlled Laser Explanation**
**Atmospheric Considerations**
**Attenuation as a Function of Elevation Angle**
**Scintillation Effects Considered**

***ANSI Z136.6 Revision***

## Changes    (continued)

**Appendices**
**A – Reporting Requirements – Shortened to Remove Redundancy from Other Standards**
**B – Examples – Revised and Expanded**
**Multi-wavelength Hazard Classification**
**Viewing Aids with Mid-IR Lasers**
**Examples from ANSI Z136.1**
**C – Atmospheric Effects – Includes Scintillation**
**D – Measurement Techniques – Removed**
** ****I –  Sample Report Format – Removed**
