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.

Petroleum Pump System Operators, Refinery Operators, and Gaugers

Installing and operating tactical fuel systems to receive, store, and dispense petroleum transfers directly to the petroleum-transfer portion of this occupation.

How to prepare: Seek hands-on training in fixed-site pump controls and tank-transfer monitoring, targeting petroleum-transfer openings rather than refinery-processing positions.

What the civilian work involves
  • Signal other workers by telephone or radio to operate pumps, open and close valves, and check temperatures.
  • Monitor process indicators, instruments, gauges, and meters to detect and report any possible problems.
  • Start pumps and open valves or use automated equipment to regulate the flow of oil in pipelines and into and out of tanks.
Civilian tools and software (examples)
  • Inventory tracking software
