Which action would NOT be part of preventing occupational lung disease?

• A. Respiratory protection.
• B. Smoking cessation.
• C. Workplace exposure control.
• D. Exposing workers to high levels of dust.

Answer: (D)

Preventing occupational lung disease centers on reducing how much harmful dust or fumes workers breathe and lowering overall risk factors. Using respiratory protection helps when the hazard can’t be fully removed, by lowering the inhaled dose. Smoking cessation reduces the baseline risk to the lungs, making workers less susceptible to lung disease and cancer. Workplace exposure control aims to minimize or eliminate exposure through engineering controls (like ventilation and dust suppression) and administrative strategies (such as training and job rotation). Exposing workers to high levels of dust would not be part of prevention because it increases exposure to harmful particles and directly raises the risk of lung disease.
