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.

Chemical Equipment Operators and Tenders

Operating a submarine low pressure electrolyzer provides directly related experience for operating equipment in which chemical reactions take place.

How to prepare: Take a chemical-process safety course focused on preventing fires and explosions around operating equipment.

What the civilian work involves
  • Control or operate equipment in which chemical changes or reactions take place during the processing of industrial or consumer products.
  • Observe safety precautions to prevent fires or explosions.
  • Patrol work areas to detect leaks or equipment malfunctions or to monitor operating conditions.

Industrial Machinery Mechanics

Required mechanical maintenance on submarine electrolyzers transfers to maintaining industrial processing machinery.

How to prepare: Complete a hands-on industrial maintenance course covering machinery disassembly, component replacement, and reassembly.

What the civilian work involves
  • Repair or maintain the operating condition of industrial production or processing machinery or equipment.
  • Disassemble machinery or equipment to remove parts and make repairs.
  • Reassemble equipment after completion of inspections, testing, or repairs.
