Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Emergency Management Directors

Planning CBRN consequence management, coordinating interagency operations, and supporting civil authorities transfer directly to emergency preparedness and response coordination.

How to prepare: Develop a civilian hazardous-materials response plan that identifies local agency responsibilities, response resources, and coordination procedures.

What the civilian work involves

Consult with officials of local and area governments, schools, hospitals, and other institutions to determine their needs and capabilities in the event of a natural disaster or other emergency.
Develop and maintain liaisons with municipalities, county departments, and similar entities to facilitate plan development, response effort coordination, and exchanges of personnel and equipment.
Coordinate disaster response or crisis management activities, such as ordering evacuations, opening public shelters, and implementing special needs plans and programs.
