• A. Industrial Hygienist
• B. Occupational Health Nurse
• C. Environmental Scientist
• D. Safety Technician

Answer: (A)

Industrial hygienists are professionals who study how chemical and physical agents affect workers, especially at different exposure levels. They use engineering and scientific knowledge from fields like engineering, physics, chemistry, and biology to assess workplace hazards, measure exposure (air contaminants, noise, heat, radiation), and understand how those exposures relate to health risks. Their core aim is to control risks through the hierarchy of controls—prioritizing engineering controls to remove or reduce the hazard, followed by administrative changes and appropriate personal protective equipment. This focus on exposure assessment, health effects, and practical hazard control fits the description precisely. Other roles differ in emphasis: an occupational health nurse centers on medical care and health surveillance for workers; an environmental scientist typically studies environmental impacts and health effects outside the workplace; a safety technician focuses on general safety compliance and incident prevention rather than in-depth exposure assessment and health risk management inside occupational settings.
