Why is it important to label the bag after taking a tape sample?

Labeling the bag after taking a tape sample is crucial primarily for identification purposes. Each sample must be clearly marked to indicate the specific area from which it was collected. This identification helps in accurately correlating the results of the analysis to the exact location and conditions of the sample. In occupational hygiene, understanding where a sample originated can provide insights into potential exposure risks and assist in evaluating workplace safety effectively.

While other aspects like proper disposal, hygiene, and contamination prevention are also important in the broader context of handling samples, the core purpose of labeling directly addresses the need to track and trace the location of the sample. This becomes essential especially in scenarios involving multiple samples or complex environments where accurate identification is vital for effective monitoring and risk assessment.
