Occupational Health and Safety major

Occupational Health and Safety: courses, careers, and where to study

Occupational health and safety trains you to spot, measure, and reduce workplace hazards, suiting students who want to keep workers safe and employers compliant.

Occupational health and safety is the applied field of protecting people from harm on the job, and it sits at the meeting point of public health, environmental science, and workplace regulation. Students learn to recognize the things that injure or sicken workers over time, from loud machinery and toxic fumes to repetitive lifting and confined spaces, then to measure those exposures and bring them down to safe levels. Coursework moves from human anatomy and toxicology, which explain how the body responds to chemicals, noise, dust, and heat, into hands-on hazard assessment, where you use instruments to sample air, measure sound, and check ventilation. You also study the rules that govern American workplaces, learn to read and apply federal and state safety standards, investigate incidents to find root causes, and write the programs and training that prevent the next one. This is the practical, prevention-focused cousin of broader environmental health: rather than studying ecosystems or community pollution at large, the focus stays squarely on the work environment and the worker inside it.

Most roles tied to this major start with a bachelor's degree, and many programs build in laboratory work with monitoring equipment, a field-based internship or practicum at a job site, and a capstone safety project that pulls the coursework together. Some specialist tracks lead toward voluntary professional certification earned through exams and supervised experience after graduation, and certain employer or state roles may expect a specific credential, so prospective students should confirm whether programmatic accreditation or any state or certification requirement applies to the path they want. Graduates often work as safety specialists or industrial hygienists in manufacturing plants, construction firms, hospitals, mines, warehouses, energy and chemical operations, and government inspection agencies, where they audit conditions, run training, respond to incidents, and keep an organization in line with safety law.

In federal data for the closely related occupation of occupational health and safety specialists, the U.S. Bureau of Labor Statistics reports a 2024 median wage of $83,910 and projects employment to grow about 12.5% from 2024 to 2034; a bachelor's degree is the typical entry-level education for that occupation. National figures are occupation-wide medians across all experience levels, not starting wages or graduate outcomes.
