Results for Alcohol Experimentation Mouth
Alcohol Results
Conclusions: Through this experiment, it is evident that the effects of Mouth Alcohol do not affect the overall Blood Alcohol Concentration readings on an Intoxilyzer SD-5 unless the subject test is taken shortly after alcohol is placed in the mouth. When undertaking any breath instrument test, the operator should always make sure that the last drink was consumed and no new alcohol was introduced into the mouth 15-20 minutes prior to the test. It is also evident that recent mouth alcohol can have a profound impact on the readings of the Intoxilyzer SD-5. |
