What is the primary purpose of medical surveillance in occupational health?

• A. To replace environmental monitoring
• B. To systematically assess employees exposed or potentially exposed to occupational hazards
• C. To measure chemical concentrations in air
• D. To reduce occupational accidents

Answer: (B)

Medical surveillance in occupational health is about monitoring the health of workers who are exposed or may be exposed to hazards through systematic health assessments, screenings, and follow-up. Its primary purpose is to detect early signs of work-related illness, track health trends over time, and use that information to adjust exposure controls, provide timely interventions, or reassign tasks as needed to protect workers’ health. This is distinct from environmental monitoring, which measures the actual levels of hazards in the workplace (such as chemical concentrations or noise). Medical surveillance focuses on the worker’s health status, not on measuring the hazard itself. While reducing occupational accidents is a broader safety objective, medical surveillance directly supports health protection by catching early effects and informing safer work practices and controls.
