What should operators be cautious about when interpreting positive BAC results?

When interpreting positive Blood Alcohol Concentration (BAC) results from the Intoxilyzer 8000, it is essential to recognize that these results may require confirmation due to possible interference. Various factors can influence the accuracy of the readings, including the presence of substances other than alcohol (like certain mouthwash or breath fresheners) that could lead to false positives. Additionally, environmental factors, user error, or the calibration status of the device can also affect the reliability of the results. Therefore, it's prudent for operators to consider the possibility of interference before drawing conclusions about a person's level of intoxication. This cautious approach ensures that judgments made based on the BAC results are founded on reliable and confirmed data.
