What medical surveillance is required for workers with asbestos exposure above the action level?

• A. No medical surveillance is required.
• B. Medical surveillance is required only for supervisors.
• C. Medical surveillance is optional.
• D. Periodic medical examinations as required by regulations, typically baseline and periodic exams with appropriate medical questions and tests.

Answer: (D)

Exposure above the action level triggers regulatory-required medical surveillance. This means workers must undergo periodic health examinations to monitor for early signs of asbestos-related disease. The program typically starts with a baseline exam and continues with regular follow-up exams, including a medical history focused on respiratory health, a physical exam, and tests such as pulmonary function testing and chest imaging as indicated. The goal is early detection and appropriate medical management, not to guess or rely on self-report alone. Other options are not correct because surveillance is mandated (not optional), it applies to workers above the action level (not only supervisors), and it is not omitted altogether.
