Which statement about the scope of occupational hygiene is true?

• A. It includes treatment of occupational diseases
• B. It includes exposure assessment and control
• C. It ignores health outcomes
• D. It focuses only on aesthetics

Answer: (B)

In occupational hygiene, the aim is to prevent work-related illness by understanding how workers are exposed to hazards and reducing those exposures. This means identifying potential hazards in the workplace, quantifying or estimating how much workers are exposed, and then applying controls to lower the risk. The usual approach follows a hierarchy of controls: eliminate or substitute the hazard if possible, implement engineering controls to remove or reduce exposure, adopt administrative controls to change how work is done, and use personal protective equipment when necessary. After controls are put in place, exposures are re-evaluated to verify that they meet safe levels and that health protection is achieved. This fits the statement about exposure assessment and control being part of the scope because quantifying exposures and taking steps to reduce them are fundamental to protecting worker health. It’s not about treating occupational diseases—that belongs to medical care—nor is it about aesthetics. Health outcomes matter and are central to preventing harm rather than ignoring effects.
