Track your B.A.C. – BACTRACK!

The BACTRACK® Select S30 Breathalyzer is an alcohol screening
device, used for the detection of alcohol in the breath. The
BACTRACK provides a digital result, displaying an estimate of
the subject’s BAC (Blood Alcohol Content). Before you begin
testing, it is very important to read the entire owner’s manual.
It is also very important to have the instrument calibrated
periodically as recommended on page 12. Failure to do so
may result in readings that are inaccurate.

Alcohol and Its Effects on the Human Body

When a person consumes alcohol, the alcohol is absorbed from
the mouth, throat, stomach and intestines into the bloodstream.
The alcohol in the bloodstream exchanges with air deep in
the lungs. The percent of alcohol in a person’s blood (BAC)
is proportional to the percent of alcohol in a person’s breath
(BrAC). The BACTRACK measures a subject’s deep lung air
alcohol level and converts it to the estimated BAC.

“BAC” means Blood Alcohol Concentration. It is measured in %.

How does alcohol affect my body?

Alcohol is a depressant. It has a relaxing effect on the muscles in
your body. The muscles of your eyes relax and lose focus. Your

eyesight will become fuzzy and you may experience double
vision. Brain activity is slowed. Your judgment, reflexes, and
coordination are all negatively affected. Some vision impairments
that occur when you have been drinking include:

Narrowing of your field of vision•
Reduction in your depth perception•
Decreased ability to see in darkness•
Increased sensitivity to glare and a longer time for your •

eyes to readjust from the glare

Some mental (brain) impairment can occur when you have been
drinking, including:

Reduced awareness of danger•
Becoming overly confident and reckless•
Difficulty in making decisions•
Reduction in balance•
Slowed reflexes•
Impaired judgment•

Variations among individuals and other factors, such as altitude
and air temperature, affect the degree of intoxication. Some
individuals may become intoxicated at low BAC levels. A low
BAC on a breath alcohol tester does not mean that a person’s
reaction times can respond to any emergency encountered.
Individuals should not drink alcohol and drive or use any
machinery after consuming alcohol.

How does alcohol affect my driving?

We can’t emphasize enough how dangerous it is for you to
drink and drive. Your vision and your brain are the most
important factors in driving safely. If you jeopardize either by
drinking, and then you drive, you are likely to be involved in
a serious or fatal collision.

There is no safe way to drive under the influence of
alcohol. Even one drink can make you unsafe.

* The effects of alcohol intoxication are greatly influenced by

individual variations among users. Some users will be intoxicated
at a much lower BAC than shown above.

**Death can occur at a lower BAC in some individuals.

The generally accepted legal standard for alcohol intoxication in the
United States is 0.08%. However, your driving skills can be impaired
at a level of 0.04% or lower. It is never safe to drink any amount of
alcohol and drive.

Loss of consciousness.

Onset of coma. Possible death due
to respiratory arrest**.
