An occupational health nurse (OHN) works within a company or organization to protect employees from workplace injuries, manage illness and disability cases, and promote long-term health. The role blends clinical nursing skills with knowledge of workplace safety regulations, workers’ compensation, and public health. Rather than treating patients in a hospital or clinic, these nurses focus on keeping workers healthy and productive in their specific work environment.
Day-to-Day Clinical Responsibilities
The most visible part of the job is hands-on care for employees who get sick or hurt at work. An occupational health nurse treats workplace injuries, performs first aid, and decides whether someone needs to be sent to an emergency room or specialist. Beyond acute care, they run routine health screenings that are tailored to the hazards employees face. Workers exposed to loud machinery may get regular hearing tests (audiometric evaluations). Those around dust, chemicals, or other airborne substances may undergo lung function tests or chest X-rays. Nurses also administer questionnaires to catch early signs of conditions like occupational asthma or contact dermatitis before they become serious.
Immunization programs, blood pressure checks, and chronic disease monitoring round out the clinical side. In many workplaces, the OHN is the only healthcare professional on-site, which means they also provide CPR, Stop the Bleed training, and active shooter preparedness to other employees.
Hazard Detection and Workplace Safety
Occupational health nurses don’t just wait for injuries to happen. A core part of the role is identifying hazards before they cause harm. This means walking through the workplace to assess risks across four main categories: personnel behavior, technical processes, the physical environment, and management practices. Common issues they flag include inadequate ventilation, crowded workspaces, poor lighting, irregular use of personal protective equipment, and missing warning signs for exposure risks.
When patterns emerge, such as a cluster of back injuries in one department or rising reports of skin irritation near a chemical process, the nurse investigates. They analyze health data across groups of workers to spot trends that individual employees might not notice on their own. From there, they recommend changes: adjusting workstation ergonomics, introducing safety distance markers, expanding a cramped treatment area, or requiring new protective gear. During public health emergencies or pandemic situations, this pattern-detection role becomes especially critical.
Case Management and Return-to-Work Coordination
When a worker is injured or becomes seriously ill, the occupational health nurse often serves as the case manager who keeps everything on track. This means coordinating between the employee, their doctor, the employer, and the insurance provider. The goal is to make sure the worker gets timely medical treatment while also navigating the paperwork side: workers’ compensation claims, Family Medical Leave Act (FMLA) documentation, and short-term or long-term disability benefits.
The nurse identifies barriers to recovery, whether that’s a delayed specialist referral, a confusing treatment plan, or a workplace that hasn’t been modified to accommodate restrictions. They then communicate those barriers to everyone involved and help develop a plan to resolve them. For employees returning after an injury, the OHN helps design a return-to-work plan that matches their current physical capabilities, which often involves temporary job modifications or phased schedules.
Regulatory Compliance and Recordkeeping
Occupational health nurses are often the person responsible for making sure the company follows OSHA regulations. This includes maintaining OSHA 300 logs, which are required for employers with more than ten employees in most industries. Every work-related injury or illness that requires treatment beyond basic first aid must be documented on these logs. Fatalities must be reported to OSHA within 8 hours, and in-patient hospitalizations, amputations, or loss of an eye must be reported within 24 hours.
The recordkeeping obligations go deeper than incident logs. OSHA requires that occupational medical records be kept for 30 years after an employee leaves the company, and employees can request access to their own records at no cost within 15 days. The nurse also ensures the workplace maintains safety data sheets for every hazardous chemical on-site, as required by OSHA’s Hazard Communication Standard. Beyond OSHA, the OHN helps the employer stay compliant with HIPAA (protecting employee health information) and FMLA requirements.
Wellness Programs and Health Promotion
Prevention is a major part of the role. Occupational health nurses design and run programs aimed at reducing the risk of disease and injury across the workforce. These programs cover a wide range: smoking cessation support, exercise and fitness initiatives, nutrition and weight management education, stress management workshops, and guidance on using medical services effectively. The idea is to address health holistically, recognizing that an employee’s well-being depends on balance among work demands, family life, and personal health.
Mental Health Support and Counseling
Occupational health nurses frequently serve as a first point of contact for employees dealing with personal or psychological struggles that affect their work. This includes substance abuse, stress, grief, and other psychosocial concerns. A nurse with strong diagnostic and interviewing skills can often intervene with a troubled employee before their job performance deteriorates visibly.
In many organizations, the OHN manages or coordinates referrals to the company’s Employee Assistance Program (EAP), which provides confidential counseling and support services. When no formal EAP exists, the nurse connects employees with community resources. They also handle follow-up to make sure employees actually receive the help they were referred to, closing the gap between a referral and real support.
Where Occupational Health Nurses Work
These nurses are found across nearly every industry. Manufacturing plants, chemical facilities, construction companies, corporate offices, government agencies, and hospitals all employ occupational health nurses. In hospital settings specifically, staff face a unique combination of routine workplace hazards plus risks specific to healthcare: needle sticks, chemical exposures, infectious disease, and physical strain from patient handling. Nurses in critical care and toxicology units face the highest rates of low back pain, burnout, and occupational injuries compared to those on general inpatient wards.
Some OHNs work for a single large employer on-site. Others work for occupational health consulting firms that serve multiple companies. A smaller number work in government roles, helping set or enforce workplace safety standards.
Education, Certification, and Salary
An occupational health nurse starts as a registered nurse (RN), which requires either an associate’s or bachelor’s degree in nursing plus a passing score on the NCLEX-RN licensing exam. From there, many pursue specialty certification. The Certified Occupational Health Nurse (COHN) credential requires an active RN license and 3,000 hours of occupational health nursing experience within the previous five years. Candidates then pass a 160-question national exam administered by the American Board for Occupational Health Nurses.
The median annual salary for registered nurses overall was $93,600 in 2024, according to the Bureau of Labor Statistics. Occupational health nurses with specialty certification and experience in high-demand industries can earn above that median. Employment of registered nurses is projected to grow 5 percent from 2024 to 2034, faster than the average for all occupations, and the specialized knowledge occupational health nurses bring makes them particularly valuable as workplace safety regulations continue to expand.
