This Air Force Policy Directive (AFPD) establishes Air Force military-specific directed energy
system safety policy. Directed energy systems provide unique capabilities and produce a broad
spectrum of hazards. This AFPD implements the applicable portions of Department of Defense
(DoD) Instruction (DoDI) 3200.19, Non- Lethal Weapons (NLW) Human Effects
Characterization; DoDI 6055.15, DoD Laser Protection Program; and DoDI 6055.11,
Protecting Personnel from Electromagnetic Fields. This publication applies to Regular Air
Force, Air Force Reserve, and Air National Guard units and personnel. Ensure all records created
as a result of processes prescribed in this publication are maintained in accordance with Air
Force Manual (AFMAN) 33-363, Management of Records, and disposed of in accordance with
the Air Force Records Disposition Schedule located in the Air Force Records Information
Management System. Refer recommended changes and questions about this publication to the
Office of Primary Responsibility using the AF Form 847, Recommendation for Change of
Publication; route AF Form 847 from the field through the appropriate functional chain of
command. This publication may not be supplemented. Major commands, field operating
agencies, and direct reporting units, if applicable, will not issue instructions that implement this
policy directive without Air Force Chief of Safety (AF/SE) approval.
SUMMARY OF CHANGES
This document has been substantially revised and needs to be completely reviewed. Major
changes include incorporation of military-specific directed energy systems into policy, updated
definitions, clarified military-specific acoustic system policy, and minimized acronym use.
