How should samples be handled immediately after collection?

Samples should be labeled, sealed, and transported to a laboratory for analysis immediately after collection to ensure their integrity and accuracy in testing. Proper handling is crucial because it minimizes the risk of contamination, preserves the sample's original state, and allows for reliable results when analyzed. Labeling creates an unambiguous reference to the source and context of the sample, which is essential for tracking and reporting purposes. Sealing prevents any additional variables from affecting the sample after collection, such as moisture or external contaminants, which could compromise the analysis results. Thus, this method is the standard practice in asbestos air monitoring and ensures compliance with health and safety regulations.
