This document applies to safety observers or spotters involved with the use of outdoor laser systems. It may be used in conjunction with SAE Aerospace Standard (AS4970) "Human Factors Considerations for Outdoor Laser Operations in the Navigable Airspace." Additional control measures may be applicable and are listed in ANSI Z-136.6-2000.

Purpose:

The purpose of this document is to provide guidance to proprietors for the optimal use of safety observers during operation of a laser system. It also recommends the minimum requirements for a safety observer.

Field of Application:

SAE AS4970 and ANSI Z136.6 provide guidance and information for the evaluation of laser operations in navigable airspace. Due to operational/mission requirements, some laser beams may exceed the maximum permissible exposure (MPE) limits or visual interference levels as defined in FAA Order 7400.2, ANSI Z136.1, and ANSI Z136.6. The use of laser safety observers as control measures to reduce the laser beam hazards to air navigation are discussed.
