Asbestos clearance testing should include air sampling by a trained, experienced licensed neutral third party while asbestos containment and engineering controls are still onsite.
Containment should never be removed until lab results that show asbestos fibers to be below the detection level.
Asbestos is a known carcinogen. Asbestos clearance testing is done to confirm that asbestos fibers are below the detection levels. This ensures both worker and occupant safety. Asbestos clearance testing also preserves the value of the building. This document should stay with the building to resolve any future questions regarding the asbestos removal of the areas of abatement.
Your architect can sign an affidavit that no asbestos materials were used in construction. This will eliminate all asbestos questions about your building, and no testing or abatement would be needed.
There are several different methods of asbestos clearance air sampling. The “gold standard” is TEM air sampling, but we also offer PCM air sampling. Please review all other pages in the Asbestos section of this website, or call John, who has a CAC license, and he will implement the correct testing strategies for your asbestos abatement clearance.
