General The fundamental concept of laser range safety is to prevent direct and collateral injury or damage resulting from laser use. Personnel using or supervising the use of lasers will be thoroughly familiar with all aspects of laser operations, systems employed, and associated dangers during training. a. Safe use of military lasers and laser systems. This chapter provides guidance for the safe use of military lasers and laser systems on military ranges as listed in MIL–HDBK–828B and JP 3–09. b. Safe treatment of lasers. Lasers will be treated as direct-fire weapons. c. Laser systems. Laser systems will be directed only at approved targets and from approved operating positions/ areas or on designated headings and altitudes. d. Laser usage. Unfiltered Class 3B, 4, or DOD-exempt lasers will be used only on certified laser ranges approved for laser usage in accordance with paragraph 16–3. These lasers will be operated only in restricted airspace. e. Nominal ocular hazard distance. The nominal ocular hazard distance (NOHD) is the distance from an operating laser to the point where the laser is no longer an eye hazard (for example, the irradiance or radiant exposure during operation is not expected to exceed the appropriate maximum permissible exposure (MPE) level). f. Unprotected personnel. Unprotected personnel must not be exposed to laser radiation within the NOHD of the laser system. 203 DA PAM 385–63 • 16 April 2014
