BAT Error Correction & Invalid Test Procedures Flashcards

What must happen when a confirmation breath alcohol test result is 0.02 or greater but the employee claims the result is wrong?

Answer: The confirmation result stands; the employee may request a re-test only through the employer's review process

The confirmation test result is final for DOT purposes; employees cannot demand an on-site re-test, though they may pursue employer review procedures.

Under DOT rules, what is a BAT required to do if the employee states they cannot produce an adequate breath sample due to a medical condition?

Answer: Document the claim and refer the employee to a physician for evaluation; the employer then decides next steps

The BAT documents the claim on the ATF and refers the employee to a licensed physician to determine if a genuine medical condition prevents adequate breath sample production.

If an EBT's air blank check result before a confirmation test is not 0.00, what must the BAT do?

Answer: Stop the test, remove the device from service, and note the failure on the ATF

A non-0.00 air blank result indicates possible device contamination; the BAT must halt the test, take the EBT out of service, and document the failure.

Under 49 CFR Part 40, what does a 'non-negative' screening test result mean for next steps?

Answer: A confirmation test using an EBT must be conducted

A non-negative screening result (0.02 or above) triggers a mandatory confirmation test using a DOT-approved EBT before any employment action can be taken.

Which of the following scenarios requires a BAT to document an 'incomplete test' rather than a 'cancelled test'?

Answer: The employee leaves the testing site voluntarily before the screening test is complete

Voluntary departure before test completion is documented as a refusal (incomplete test), not a cancelled test, because it is the employee's conduct—not a procedural error—that stopped the test.

After a test is cancelled due to a fatal flaw, is the employee required to take another test?

Answer: Yes, if the test was required by DOT, the employer must direct the employee to take another test as soon as possible

A cancelled test does not fulfill the DOT testing requirement, so the employer must direct the employee to undergo another test promptly.
