Which statement is NOT a criterion for participation in an asbestos medical surveillance program?

• A. All employees working in areas with asbestos-containing materials
• B. Employees who conduct Class I, II, and III work for more than thirty days
• C. Employees exposed over the PEL for thirty or more days in a year
• D. Contractors involved in asbestos abatement activities

Answer: (A)

Participation is based on actual exposure risk to asbestos, not simply being present in a space that contains asbestos-containing materials. Medical surveillance is triggered for workers who disturb asbestos-containing materials through their duties (Class I, II, or III work) for a substantial period, typically 30 days or more in a year, and for those with exposure to asbestos at or above the permissible exposure limit for a similar duration. Contractors who are involved in asbestos abatement are included because their activities directly involve disturbing ACM and pose exposure risk. So, the statement that all employees working in areas with asbestos-containing materials is a criterion is not correct because mere presence in an area does not guarantee exposure above the threshold or involvement in activities that require surveillance. The other criteria align with the exposure-based requirements for participation.
