What does a sample label need to do in relation to the Chain of Custody document?

The sample label needs to exactly match the information provided in the Chain of Custody document to ensure that there is consistency and accuracy throughout the handling and analysis of the sample. This matching is crucial for maintaining the integrity of the evidence and ensuring that the sample can be reliably traced back through its history and maintain its credibility in legal or regulatory contexts. Any discrepancies between the sample label and the Chain of Custody document could lead to confusion or disputes regarding the sample's origin or handling, undermining the validity of any findings associated with that sample.

When the sample label accurately reflects the details in the Chain of Custody, it reinforces the thoroughness of the process and ensures that all personnel handling the sample can quickly verify information, thereby upholding the standards needed for effective environmental response and legal accountability.
