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.

Explosives Workers, Ordnance Handling Experts, and Blasters

Planning military EOD operations provides relevant experience for civilian explosives work, although construction blasting involves different methods and competency standards.

How to prepare: Have a prospective employer assess your existing qualifications and documented EOD experience against its blasting work and applicable jurisdictional rules: OSHA construction standards require demonstrated safe, method-specific competency and knowledge of state and local explosives laws. For work involving possession of explosives, distinguish employee access from business licensing: federal license or permit holders must report newly authorized employee possessors to ATF, which conducts a background check when appropriate.

What the civilian work involves
  • Place safety cones around blast areas to alert other workers of danger zones, and signal workers as necessary to ensure that they clear blast sites prior to explosions.
