MIL-STD-1425A, DEPARTMENT OF DEFENSE DESIGN CRITERIA STANDARD: SAFETY DESIGN REQUIREMENTS FOR MILITARY LASERS AND ASSOCIATED SUPPORT EQUIPMENT (30 AUG 1991)., This MIL-STD defines safety design requirements for military equipment and associated support equipment which incorporate laser systems in their design. These requirements are the minimum requirements necessary to control the hazards caused directly by laser radiation. Associated system hazards, such as electrical shock, toxic chemicals, high pressure, etc. should be controlled through the selection of appropriate requirements in other standards and specifications. All military laser development programs should include a comprehensive system safety program in accordance with Military Standard (MIL-STD) 992 System Safety Program Requirements, to identify and control all hazards unique to the specific laser product under development.
