What action should be taken when an "Ambient Fail" occurs during testing?

When an "Ambient Fail" occurs during testing, it indicates that there is an issue with the environment in which the test is being conducted, particularly concerning the presence of interfering substances that could skew the results. Addressing this situation appropriately is crucial to ensure the accuracy of the test results.

Ventilating the area helps to eliminate any potential contaminants or environmental factors that may be affecting the readings of the Intoxilyzer 9000. After ensuring that the area is adequately ventilated and that any sources of interference have been removed, retesting can then be performed. This step ensures that the operator can obtain a valid and accurate test result without the influence of external factors.

In contrast, stopping the test without addressing the environmental issue or retesting immediately without proper precautions would not rectify the fault indicated by the "Ambient Fail." Requesting a blood specimen might be considered in certain scenarios, but it does not directly resolve the problem with the testing environment, which is necessary to ensure the integrity of the breath test results.
