Health Hazard Assessment (HHA) is the process used within the Army to identify, assess, and eliminate or control health hazards associated with the life cycle management of materiel items such as weapon systems, munitions, equipment, clothing, training devices, and other materiel systems.  The HHA program addresses the potential effects of materiel systems health hazards on the personnel who test, produce, use, maintain, repair, or support the systems.  Through application of biomedical knowledge and principles, HHA directly supports Army officials engaged in developing, manufacturing, operating, maintaining, demilitarizing, and disposing of materiel systems.  The HHA is systems engineering from a health or medical perspective.
