Medical Surveillance is defined as:

• A. Ongoing systematic evaluation, determines if one can perform duties; and detect changes in body caused by exposures.
• B. A one-time health screen before starting work
• C. A record-keeping system for medical interventions only
• D. A general health assessment every five years

Answer: (A)

Medical surveillance is an ongoing, systematic evaluation of a worker’s health to determine if they can perform their duties and to detect changes in the body that may result from exposures. This approach provides continuous monitoring for early effects of hazardous materials, supports keeping the worker fit for duty, and allows for timely adjustments or medical action if health changes occur. It is not just a one-time screen before work, a record-keeping system limited to medical interventions, or a general health check every several years.
