The factory worker's chronic cough is not bronchitis — it is ten years of silica dust exposure. The occupational health nurse who catches this connection saves a life; the one who treats the symptom watches a preventable disease progress.
Occupational health nursing focuses on the prevention of work-related injuries and illnesses, health promotion in the workplace, and management of occupational health hazards. The Occupational Safety and Health Administration (OSHA) sets and enforces workplace safety standards. Key OSHA requirements the nurse should know include the Hazard Communication Standard (employees have the right to know about chemical hazards through Safety Data Sheets/SDS), the Bloodborne Pathogens Standard (exposure control plan, PPE, post-exposure protocols for healthcare workers), permissible exposure limits (PELs) for chemical and physical hazards, and the employer's legal requirement to maintain an OSHA 300 log of recordable workplace injuries and illnesses (the occupational health nurse may assist with documentation, but the employer bears legal responsibility for recordkeeping). The occupational health nurse conducts workplace hazard assessments (noise levels, chemical exposures, ergonomic risks, biological hazards), performs or coordinates pre-employment and periodic health screenings (audiometry for noise-exposed workers, pulmonary function testing for respirator users, vision screening as required by job-specific safety standards), manages work-related injuries (first aid, case management, return-to-work coordination), administers workplace wellness programs, and serves as the connection between the employee, the employer, and healthcare providers. Workers' compensation is a state-mandated insurance system that covers medical expenses and lost wages for work-related injuries and illnesses — employees do not need to prove employer fault. Common occupational diseases include noise-induced hearing loss, respiratory diseases (asbestosis, silicosis, occupational asthma), musculoskeletal disorders (carpal tunnel, low back injury from repetitive lifting), dermatitis from chemical exposure, and bloodborne pathogen exposures (needlestick injuries in healthcare).
Key Distinctions
OSHA sets and enforces workplace safety standards — it is a regulatory agency, not a healthcare provider. NIOSH (National Institute for Occupational Safety and Health) conducts research and makes recommendations; OSHA writes the enforceable rules. Students confuse these agencies. Safety Data Sheets (SDS, formerly MSDS) must be accessible to all employees who work with or near hazardous chemicals — the employer cannot restrict access. The occupational health nurse maintains confidentiality of employee health records — medical information is not shared with the employer beyond fitness-for-duty determinations. Workers' compensation does NOT cover injuries that occur during a regular commute (the 'going and coming' rule), but does cover injuries during work-related travel.
Clinical Pearl
If a patient presents with a new respiratory, skin, or musculoskeletal complaint, always ask what they do for work. The diagnosis is often in the job description.
