What is displayed on the Intox if it detects mouth alcohol?

• A. Mouth alcohol
• B. Breath sample
• C. No alcohol detected
• D. Calibration required

Answer: (A)

Mouth alcohol is a warning that the breath sample is contaminated by alcohol still present in the mouth. The Intox EC/IR II has a detector for this situation, and when it senses mouth alcohol it displays a message indicating this condition rather than giving a BAC result. This protects accuracy because residual mouth alcohol can falsely raise the reading. The correct display in this case is shown as mouth alcohol, meaning the operator should discard the current sample, wait for the mouth alcohol to dissipate (typically a 15-minute observation period with no intake or mouth products), and then perform a new test to obtain a valid result.
