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.

Occupational Health and Safety Specialists

Military experience evaluating occupational health hazards and recommending risk controls transfers directly to workplace hazard assessment and prevention.

How to prepare: Build a sample workplace hazard assessment linking each identified hazard to a proposed control. Specialists typically need a bachelor's degree in occupational health and safety or a related field.

What the civilian work involves
  • Recommend measures to help protect workers from potentially hazardous work methods, processes, or materials.
  • Develop or maintain hygiene programs, such as noise surveys, continuous atmosphere monitoring, ventilation surveys, or asbestos management plans.
  • Inspect or evaluate workplace environments, equipment, or practices to ensure compliance with safety standards and government regulations.
Civilian tools and software (examples)
  • Microsoft Excel
  • Microsoft Word

Environmental Science and Protection Technicians, Including Health

Evaluating environmental health threats in garrison and deployed settings provides a foundation for environmental protection fieldwork.

How to prepare: Complete a practical environmental sampling course covering sample collection and test-data recording.

What the civilian work involves
  • Collect samples of gases, soils, water, industrial wastewater, or asbestos products to conduct tests on pollutant levels or identify sources of pollution.
  • Record test data and prepare reports, summaries, or charts that interpret test results.
Civilian tools and software (examples)
  • Microsoft Excel
  • Adobe Acrobat
