If the final air clearance test fails, the next required action is to:

• A. Repeat the final clearance air sample
• B. Stop work permanently
• C. Ignore the result and resume cleaning
• D. Document the result and proceed without retesting

Answer: (A)

Final air clearance testing is the objective check that a cleaned area meets the required asbestos-free standard before people re-enter. If the clearance result fails, you cannot declare the space clean or resume normal activities. The next required action is to re-clean the area and then repeat the final clearance air sampling to verify that the cleanup has achieved the necessary standard. This step ensures there is verifiable evidence of safety before occupancy. The other options—stopping work permanently, ignoring the result, or proceeding without retesting—do not provide the necessary safety measure or regulatory compliance.
