What measures must be taken by the weigher and sampler when collecting samples?

Washing hands immediately before taking samples is a critical practice in the field of sampling and weighing. This step minimizes the risk of contamination, which could significantly affect the integrity of the samples collected. Clean hands help to ensure that any external contaminants, oils, or residues do not mix with the samples, thus preserving the accuracy and reliability of analytical testing.

By maintaining high hygiene standards, the weigher and sampler can protect the quality and credibility of the sample analysis process. Proper handwashing practices not only comply with industry standards but also foster trust in the sampling process, which is essential for achieving valid and reproducible results in various applications, including food testing, environmental analysis, and product quality control.
