Who is responsible for conducting the pre-collection inspection of the latrine?

The individual responsible for conducting the pre-collection inspection of the latrine is the Unit Prevention Leader (UPL). The UPL holds a critical role in ensuring the integrity of the substance abuse prevention program within the unit, which includes supervising and maintaining standards for collection procedures, including inspection of facilities used during testing.

By overseeing the pre-collection inspection, the UPL ensures that the testing environment is appropriate and that the chain of custody is maintained. This responsibility is crucial to uphold the accuracy and reliability of the urinalysis process and to prevent any potential contamination or compromise of the samples being collected.

The roles of other positions like the First Sergeant, Commander, or Designated Soldier may include broader oversight or support for the drug prevention program, but they do not specifically carry the detailed responsibility for the inspection of the latrine in preparation for the collection process. Thus, the UPL's specialized training and focus on substance abuse prevention make them the correct choice for this task.
