The primary focus of the Air Force Emergency Management Program is to save lives, minimize the loss or degradation of resources, and ensure continued operational capability at all times. Emergency management teams, located at all military installations, are trained and equipped to respond to threats including: chemical, biological, radiological, nuclear and high-yield explosives (CBRNE); weapons of mass destruction; hazardous material incidents; natural disasters; and major accidents. Emergency management teams work closely with and support national, state, local, and civilian response agencies. The program supports homeland security operations and provides support to civil and host-nation authorities, in accordance with Department of Defense directives, and through the appropriate Combatant Command.
