What is an Occupational Health Nurse?

Nearly three million people are injured at work every year. Occupational health nurses, also called environmental health nurses, are the ones companies put in place to prevent those injuries and treat them when they happen. They identify workplace hazards, build safety protocols, train staff, and handle the clinical side when someone gets hurt. They also run the routine work: new-hire physicals, annual flu shots, and employee drug testing.

At a Glance

Where you'll work: Large corporations, military bases, urgent care centers, hospitals, academic settings, and high-risk sites like construction zones, warehouses, and factories.

What you'll do: Promote health and safety on the job, running programs that prevent and treat workplace illness, injury, and hazards.

Minimum degree: ADN or BSN, though most employers prefer a BSN.

Who it fits: Nurses who want a non-traditional setting and are comfortable mixing clinical, administrative, and educational work.

Certification: The American Board for Occupational Health Nurses (ABOHN) offers the Certified Occupational Health Nurse (COHN) credential, which signals expertise and can lead to better roles and pay.

Median annual salary: $93,600

Most occupational health nurses have at least a bachelor's degree, and a master's can push your career further. You will also need a few years of general RN experience first. "Over the past several years, our list of responsibilities has grown exponentially," says Christina Whalen, RN, vice president of clinical operations at Intuitive Health in Plano, Texas. "You must be savvy at many different things, administering care, bedside care, inventory, and other necessary tasks to keep the system running."

How to Become an Occupational Health Nurse

Start by earning RN licensure through an ADN or BSN. Either qualifies you to take the NCLEX-RN and apply for licensure in your state.

A few BSN programs offer occupational health as a concentration, but it is uncommon. You can still prepare during your education:

Focus on relevant classes. Take coursework in occupational, environmental, and public health to build a foundation for the specialty.

Gain experience as a nurse. Most occupational health roles are not entry-level. Many nurses start in emergency rooms or critical care units, where they sharpen the assessment, injury-management, and crisis-response skills the job demands.

Advancing Your Career

You can enroll in a bridge program and earn an MSN or DNP. Occupational health is not a standalone advanced-practice specialty, but you can add it as a concentration to another one. For example, you might earn an MSN as a family nurse practitioner with an occupational health concentration. An advanced degree positions you to work as a consultant traveling between sites, or to move into policy and workplace safety regulation.

What Occupational Health Nurses Do

Occupational health nurses care for employees at work, in a clinical role, an administrative role, or both.

In a clinical role, they:

• Assess the employee and the extent of the injury
• Decide whether to treat onsite or send the worker out for care
• Investigate how the injury happened and whether the workplace was at fault

The job also runs well beyond injuries:

• Keeping workplaces compliant with Occupational Safety and Health Act (OSHA) standards
• Building programs to prevent accidents and promote healthy living
• Counseling employees and referring them to assistance programs
• Administering medications and flu shots
• Performing new-hire physicals and drug tests
• Managing workers' compensation, FMLA, and short- and long-term disability claims

"Our job is to get the medical process started, that's gathering information, vitals, and topics of concern before a doctor even enters the picture," Whalen says. "We start asking questions, evaluating, begin lab work if necessary, and take the initiative to make sure our patients receive care immediately."

Where They Work

Large companies often keep occupational health nurses on staff, and hazardous or physical workplaces like warehouses, plants, and factories rely on them heavily. Many work as consultants, traveling between companies to handle OSHA compliance and safety protocols. Other common settings include academic institutions, hospitals, government facilities, entertainment venues, retail complexes, construction sites, and military bases.

Urgent care centers are a newer option. Many smaller companies now send employees there for physicals, drug testing, and workplace injuries. Nurses in these clinics serve those companies but are employed by the urgent care center. "Most individuals default to the highest level of care available because they don't know where to get treatment," Whalen says. "Urgent care clinics have popped up across the country to deliver accessible health care at a fraction of the cost of an emergency department."

Occupational Health Nurse vs. Occupational Therapist

The titles look alike; the jobs are not. Occupational therapists help people gain or regain everyday skills, like teaching a child with developmental delays to dress or helping a stroke patient relearn to brush their teeth. They work in hospitals, outpatient centers, and skilled nursing facilities. Occupational health nurses treat workplace injuries and build safety programs, usually in corporate settings, urgent care centers, plants, and construction sites.

Licenses and Certifications

You need an RN license to practice. Beyond that, ABOHN offers two certifications. Neither is required, but both demonstrate the experience and judgment the role demands and can help you land more advanced positions.

Certified Occupational Health Nurse (COHN): A clinical certification. Requires an active RN license and at least 3,000 hours of occupational health nursing experience in the past five years.

Certified Occupational Health Nurse-Specialist (COHN-S): An administrative certification. Requires a bachelor's degree, an active RN license, and at least 3,000 hours of experience in the past five years.

ABOHN does not rank the COHN-S above the COHN. Choose based on focus: the COHN suits hands-on clinical work, the COHN-S suits administrative work like designing safety education programs.

Salary and Career Outlook

The BLS does not track occupational health nurses specifically, but it reports a median RN salary of $93,600, and experienced, certified nurses in this specialty often earn above the RN average. The BLS projects 4.9% job growth for RNs through 2034.

Shifting health and safety regulations at the state and federal level will keep driving demand. "I think occupational health nurses will be a significant component to any industry development," Whalen says. "Long gone are the days of nurses who wait for doctors' orders. We play a valuable role in the medical field and can make decisions based on our patients' needs."

Professional Resources

Staying current on OSHA and other regulations is part of the job. Two organizations worth following:

American Association of Occupational Health Nurses (AAOHN): Conferences, career building, continuing education, and advocacy.

Association of Occupational Health Professionals in Healthcare (AOHP): Networking, webinars, journals, and conferences.
