When is a licensed asbestos supervisor required on a project?

• A. For projects under 10 hours.
• B. Only for renovation projects.
• C. Only for manufacturing installations.
• D. For regulated asbestos abatement activities as required by state/local licensing requirements.

Answer: (D)

The main idea is that a licensed asbestos supervisor is required whenever the work involves regulated asbestos abatement activities, as defined by state or local licensing rules. When asbestos-containing materials are disturbed in a way that could release fibers—such as removal, encapsulation, enclosure, or certain repairs—these activities must be overseen by someone with the proper certification. The supervisor’s job is to ensure the work follows approved plans, uses proper containment and engineering controls, conducts any required air monitoring, handles waste correctly, and ensures clearance is achieved after completion. The other scenarios don’t automatically require a licensed supervisor unless they themselves involve regulated abatement work. So the obligation comes from the licensing requirements tied to regulated asbestos abatement activities, not simply from the project type or scale.
