What is the significance of a sealed blank sample?

A sealed blank sample serves as a control sample in asbestos testing and analysis. The purpose of this control sample is to ensure the reliability and accuracy of the test results, allowing for the identification of any potential contamination that may occur during sampling and analysis. By comparing results from actual samples to those obtained from the blank sample, professionals can determine whether any measured asbestos fibers are due to the sample itself or if they resulted from external sources or contamination.

In context, while calibration of equipment is crucial in laboratory processes, it does not specifically relate to the role of a sealed blank sample, which is focused on quality control. Tracking airborne asbestos fibers and determining project size involve different methodologies and tools, making them distinct from the function of a control sample. Thus, the role of a blank sample is primarily to provide a basis for comparison and assurance of the integrity of the sample analysis.
