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 Technicians

Maintaining CBRN protective equipment, training personnel in protective measures, and reporting exposure information transfer to workplace hazard monitoring and protective equipment support.

How to prepare: Target technician openings that provide on-the-job training in workplace inspections, hazard testing, and safety regulations; typical entry requires at least a high school diploma, while some technicians complete a safety certificate or associate's degree.

What the civilian work involves
  • Supply, operate, or maintain personal protective equipment.
  • Maintain all required environmental records and documentation.
  • Test workplaces for environmental hazards, such as exposure to radiation, chemical or biological hazards, or excessive noise.

Environmental Science and Protection Technicians, Including Health

Collecting, analyzing, and reporting information about CBR exposure and contaminated areas provides a foundation for environmental hazard investigation and test-result reporting.

How to prepare: Compare your completed education with local openings and identify any gaps in natural-science coursework and laboratory practice. Entry typically calls for an associate's degree in environmental science, environmental health, public health, or a related field, but requirements range from a high school diploma to a bachelor's degree depending on the position.

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.
  • Investigate hazardous conditions or spills or outbreaks of disease or food poisoning, collecting samples for analysis.
