After the BAT has instructed the employee regarding the deprivation period between a positive screening and confirmation test, what should the BAT do if the employee belches?
Correct Answer:
Note this in remarks on the ATF and conduct confirmation test after the 15 minute wait
Explanation:
Belching during the 15-minute deprivation period is a documented event you should record, and you still proceed with the confirmation test after that waiting period. The 15-minute wait exists to reduce the chance that residual mouth alcohol skews the confirmation result, so belching doesn’t automatically reset or cancel the process—you just note what happened in the remarks on the ATF and then complete the confirmation test once the wait is over. Canceling the test or pausing longer than specified isn’t warranted, and ignoring the belch wouldn’t meet testing procedures.
