If you blow a failing breath sample and you believe it’s due to a contaminant, it’s important to continue providing samples until a clean one is registered to show the dissipation because all interlock providers hold you responsible to any BrAC reading, no matter the source. If you do have a positive BrAC reading from a contaminant, it will dissipate much faster than a reading due to the consumption of an alcoholic beverage. If your false positive is due to a contaminant, clear the air in your vehicle or rinse your mouth with water, and then submit another breath sample.
