Which statement correctly describes the purpose of aggressive air sampling?

• A. To make residual fibers on surfaces airborne, simulating building occupancy and activity
• B. To show that no fibers are present
• C. To decrease airflow in the area
• D. To measure surface temperature

Answer: (A)

Aggressive air sampling is used to test how fibers could be released into the air when the area is disturbed or occupied. By deliberately simulating typical activities that might happen in a building, fibers that remain on surfaces can be kicked up into the air and measured. This helps determine whether controls like containment, negative pressure, and HEPA filtration are effective at limiting airborne exposure under real-world conditions. It’s about revealing potential worst‑case scenarios to ensure safety, not about proving that no fibers are present, decreasing airflow, or measuring surface temperature.
