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.

Gas Plant Operators

Operating liquid oxygen and nitrogen generating plants, vaporizing equipment, and purity analyzers transfers directly to industrial gas processing and equipment monitoring.

How to prepare: Take a gas-process controls course covering panel operation and temperature, pressure, and flow monitoring, targeting industrial oxygen and nitrogen facilities.

What the civilian work involves
  • Monitor equipment functioning, observe temperature, level, and flow gauges, and perform regular unit checks to ensure that all equipment is operating as it should.
  • Distribute or process gas for utility companies or industrial plants, using panel boards, control boards, and semi-automatic equipment.
  • Record, review, and compile operations records, test results, and gauge readings such as temperatures, pressures, concentrations, and flows.
Civilian tools and software (examples)
  • Microsoft Excel

Industrial Machinery Mechanics

Assembling and maintaining cryogenic generating plants, vacuum pumps, and vaporizing equipment provides directly relevant processing-machinery maintenance experience.

How to prepare: Complete hands-on industrial machinery repair training focused on component replacement, disassembly, and reassembly beyond the cryogenic equipment you have maintained.

What the civilian work involves
  • Repair or maintain the operating condition of industrial production or processing machinery or equipment.
  • Repair or replace broken or malfunctioning components of machinery or equipment.
  • Reassemble equipment after completion of inspections, testing, or repairs.
Civilian tools and software (examples)
  • SAP software
