Introduction to Occupational Health
Occupational health is a multidisciplinary field focused on the highest degree of physical, mental, and social well-being of workers across all occupations. It involves the prevention, identification, and management of diseases and injuries that arise from workplace activities, as well as the promotion of overall workplace wellness.
For nursing professionals, understanding occupational health principles is essential for comprehensive patient care and public health promotion. This guide provides nursing students with detailed knowledge of occupational hazards, diseases, relevant legislation, and the critical role nurses play in workplace health services.
The field of occupational health nursing combines clinical expertise with preventive healthcare approaches to address workplace-related health concerns and promote safe working environments across diverse industries.

1. Occupational Health Hazards
Occupational health hazards are workplace conditions that can cause illness, injury, or harm to workers. Identifying and mitigating these hazards is central to effective occupational health management.
Classification of Occupational Hazards
| Category | Examples | Potential Health Effects | High-Risk Industries |
|---|---|---|---|
| Physical | Noise, radiation, extreme temperatures, vibration, abnormal pressure | Hearing loss, burns, heat stroke, vibration syndrome, barotrauma | Construction, mining, manufacturing, agriculture |
| Chemical | Gases, vapors, dusts, fumes, mists, solvents | Respiratory diseases, skin disorders, cancers, organ damage | Chemical industry, painting, cleaning, printing |
| Biological | Bacteria, viruses, fungi, parasites, blood-borne pathogens | Infectious diseases, allergies, toxic reactions | Healthcare, laboratories, agriculture, wastewater management |
| Ergonomic | Repetitive movements, awkward postures, heavy lifting | Musculoskeletal disorders, carpal tunnel syndrome, back injuries | Office work, manufacturing, healthcare, transportation |
| Psychosocial | Work stress, violence, harassment, shiftwork | Mental health issues, cardiovascular diseases, sleep disorders | Healthcare, customer service, emergency services, education |
| Mechanical | Moving machinery parts, tools, vehicles | Cuts, fractures, amputations, crush injuries | Manufacturing, construction, agriculture, transportation |
Risk Assessment in Occupational Health
The HARM Framework for Risk Assessment
Remember the HARM mnemonic for effective occupational hazard assessment:
- Hazard identification – Recognize potential hazards in the workplace
- Assess exposure levels – Determine intensity and duration of exposure
- Risk characterization – Evaluate likelihood and severity of outcomes
- Management strategies – Implement control measures and interventions
Control Measures: The Hierarchy of Controls
When addressing occupational health hazards, professionals follow a hierarchy of controls, ordered from most to least effective:
-
1Elimination – Physically remove the hazard (e.g., automated processes replacing hazardous manual tasks)
-
2Substitution – Replace the hazard with a safer alternative (e.g., replacing toxic chemicals with safer ones)
-
3Engineering Controls – Isolate people from the hazard (e.g., machine guards, ventilation systems)
-
4Administrative Controls – Change work procedures (e.g., training, job rotation, safety policies)
-
5Personal Protective Equipment (PPE) – Last line of defense (e.g., masks, gloves, ear protection)
2. Occupational Diseases
Occupational diseases are health conditions that develop primarily as a result of workplace exposures. The field of occupational health dedicates significant resources to preventing, detecting, and treating these conditions.
Common Occupational Diseases
Respiratory Diseases
- Pneumoconiosis – Dust-induced lung disease (silicosis, asbestosis, coal workers’ pneumoconiosis)
- Occupational asthma – Airway inflammation from workplace sensitizers
- Chronic Obstructive Pulmonary Disease (COPD) – Exposure to dusts, chemicals, fumes
- Byssinosis – Lung disease from cotton, flax, hemp dust exposure
Skin Conditions
- Contact dermatitis – Irritant or allergic reactions to workplace substances
- Occupational vitiligo – Depigmentation from chemical exposure
- Chloracne – Acne-like eruption from halogenated compounds
- Mechanical injuries – Calluses, friction blisters, pressure injuries
Musculoskeletal Disorders
- Low back pain – Often from lifting, bending, whole body vibration
- Carpal tunnel syndrome – Compression of median nerve in wrist
- Tendinitis – Inflammation of tendons from repetitive movements
- Rotator cuff injuries – From overhead work and repeated shoulder movements
Noise-Induced Conditions
- Noise-induced hearing loss (NIHL) – Irreversible hearing damage from excessive noise
- Acoustic trauma – From sudden intense sound exposure
- Tinnitus – Ringing in ears from noise exposure
Occupational Cancers
- Lung cancer – Asbestos, radon, arsenic, chromium exposure

Diagnostic Criteria & Management Principles
Diagnostic Approach in Occupational Health
WORKER Mnemonic for Occupational Disease Assessment
- Workplace exposure history – Detailed assessment of all exposures

Management Approach
The management of occupational diseases follows these core principles:
- Primary prevention – Eliminate or reduce exposure at source
- Early detection – Health surveillance and screening programs
- Prompt intervention – Initiate treatment and remove from exposure
- Rehabilitation – Facilitate return to work with accommodations if needed
- Compensation – Support workers through benefits and disability management
- Notification – Report cases to appropriate occupational health authorities
