What does the term "agent" refer to in occupational health?

In the context of occupational health, the term "agent" refers specifically to the various hazards that can affect workers. These agents are classified into categories such as biological, chemical, physical, or psychosocial.

Biological agents include microorganisms like bacteria and viruses that can cause disease. Chemical agents encompass a wide range of substances, including toxic chemicals and irritants that may be present in the workplace. Physical agents refer to environmental factors like noise, radiation, and temperature extremes that can lead to health issues. Psychosocial agents include stressors related to the work environment, such as workload and relationships with colleagues, which can impact mental health and overall well-being.

Understanding these agents is crucial for identifying potential risks in the workplace and implementing effective health and safety measures to protect workers. This concept is foundational for occupational health professionals who aim to create a safe working environment by mitigating exposure to these various agents.
