Which elements are included in prevention of occupational lung disease?

• A. Vaccination only.
• B. Respiratory protection; Smoking cessation; Workplace exposure control; Monitoring.
• C. Regular exercise and diet.
• D. Dietary supplements.

Answer: (B)

Preventing occupational lung disease relies on a comprehensive approach that reduces exposure and catches problems early. The best answer includes respiratory protection to guard the lungs when exposure occurs, smoking cessation because smoking worsens many inhalation hazards and increases risk of disease, workplace exposure control through engineering and administrative measures to limit or eliminate hazards at the source, and monitoring to track exposure levels and workers’ health status. Together these form a proactive prevention program, addressing both the environment and the worker.

Vaccination, while valuable for specific infections, does not address most occupational lung diseases. Regular exercise and diet improve general health but do not prevent hazards from airborne contaminants. Dietary supplements have no proven role in preventing these diseases and can distract from proven controls.
