Do you need to resample materials that were already sampled before by a non-accredited individual?

Do you need to resample materials that were already sampled before by a non-accredited individual?

• A. Not if an accredited inspector signs and dates a statement that the previous samples were collected in compliance with AHERA
• B. Yes, resampling is always required
• C. Only if the previous lab results are inconclusive
• D. Only during initial surveys

Answer: (A)

The key idea is that AHERA allows previously collected samples to be used if an accredited asbestos inspector verifies the sampling was done in compliance with AHERA and signs and dates a statement to that effect. When an accredited inspector reviews the work and confirms it followed the proper procedures—who collected the samples, how many samples, where they were taken, labeling, chain of custody, and lab analysis format—the existing data can stand without resampling. This verifies the integrity of the sampling process even though the original collector wasn’t accredited. Resampling isn’t required in every case because the inspector’s certification provides the needed assurance. It would be necessary to resample only if there’s no such verification or if doubts remain about whether the sampling adhered to AHERA standards. The idea that resampling is always required, or that it’s only needed for inconclusive lab results, or that it’s limited to initial surveys, doesn’t fit how the accredited-review pathway works for validating prior work.
