How frequently should a Quality Assurance sample be taken?

  1. Every 10 samples

  2. Every 15 samples

  3. Every 20 samples

  4. Every 25 samples

The correct answer is: Every 20 samples

In accordance with the quality assurance protocols outlined in the Asbestos Hazard Emergency Response Act (AHERA), a Quality Assurance (QA) sample is typically required to be taken every 20 samples. This frequency helps ensure that the analytical procedures and methodologies used in asbestos assessments maintain their accuracy and reliability over time. By implementing a QA sample every 20 samples, it becomes feasible to monitor the consistency and overall quality of the results being obtained, thus minimizing the risk of errors in asbestos identification and quantification. This systematic approach is essential for maintaining confidence in the data collected, which is critical for ensuring health and safety in environments where asbestos may be present.
