What is the role of the collector during the handwashing process?

The correct role of the collector during the handwashing process is to supervise the handwashing. This responsibility is crucial because the collector must ensure that the handwashing procedure is followed according to established protocols. By supervising, the collector can verify that the collector adheres to the proper hygiene practices, preventing any potential issues related to sample integrity or contamination. This oversight helps maintain the reliability of the testing process, ensuring that the samples collected are valid and compliant with testing standards.

While providing soap and water is important, it typically falls under the protocol set by the testing facility rather than the direct responsibility of the collector. Ensuring no tampering occurs is also a part of a collector's duties but pertains more to the overall collection process rather than specifically to handwashing. Recording the time of washing can be relevant in some contexts, but again, it is not the primary role of the collector during this process.
