BREATH ALCOHOL TECHNICIAN (BAT) COMPLETE EXAM QUESTIONS AND
100% VERIFIED ANSWERS (PASS GUARANTEE)
1. What is a Breath Alcohol Technician (BAT)? A certified professional
trained to operate evidential breath testing devices to measure blood
alcohol concentration (BAC) in individuals.
2. What does BAC stand for? Blood Alcohol Concentration or Blood
Alcohol Content.
3. What is the legal BAC limit for commercial drivers in the US? 0.04%
or 0.04 grams of alcohol per 210 liters of breath.
4. What is the legal BAC limit for non-commercial drivers in most US
states? 0.08% or 0.08 grams of alcohol per 210 liters of breath.
5. What federal regulation governs workplace alcohol testing? 49 CFR
Part 40 - Procedures for Transportation Workplace Drug and Alcohol
Testing Programs.
6. What does DOT stand for in the context of alcohol testing?
Department of Transportation.
7. What is an Evidential Breath Testing (EBT) device? A device
approved by the National Highway Traffic Safety Administration
(NHTSA) for evidential testing that meets federal standards.
8. What is a screening test? An initial test to determine whether an
individual has a prohibited alcohol concentration.
9. What is a confirmation test? A second test following a screening test
with a result of 0.02 or greater, conducted using an EBT.
10.How long must a BAT wait between a screening and confirmation
test? At least 15 minutes but not more than 30 minutes.
,11.Why is there a waiting period between tests? To prevent mouth alcohol
from affecting the confirmation test result and to allow any residual
alcohol in the mouth to dissipate.
12.What is mouth alcohol? Alcohol present in the mouth or oral cavity that
can falsely elevate breath test results.
13.What is the partition ratio used in breath testing? 2100:1 - meaning
2100 milliliters of alveolar air contains the same amount of alcohol as 1
milliliter of blood.
14.What is alveolar air? Deep lung air from the air sacs (alveoli) where gas
exchange occurs, used for accurate breath alcohol testing.
15.Can a BAT perform tests on themselves? No, a BAT cannot conduct
their own alcohol test.
16.What is the minimum breath sample volume required? Typically 1.1
to 1.5 liters, depending on the device.
17.What temperature range must EBT devices operate within? The
range specified by the manufacturer, typically between 50°F and 95°F.
18.What is a blank test? A test performed on an EBT using ambient air to
ensure the device reads 0.00 before testing an individual.
19.What is a calibration check? A test using a reference standard to verify
the EBT is measuring accurately.
20.How often must external calibration checks be performed? At least
every 7 days or before the first test if more than 7 days have passed since
the last check.
21.What is quality assurance plan (QAP)? A document outlining
procedures for maintaining and calibrating EBT devices.
22.Who maintains the Conforming Products List (CPL)? The National
Highway Traffic Safety Administration (NHTSA).
23.What is the CPL? Conforming Products List - a list of EBT devices
approved for DOT testing.
24.Can a non-DOT test use different procedures? Yes, non-DOT tests
may follow different protocols depending on state or employer
requirements.
, 25.What is a refusal to test? When an employee fails to provide an
adequate breath sample, fails to complete testing, or refuses to sign
required forms.
26.What BAC level requires removal from safety-sensitive duties? 0.02
or greater for DOT-regulated testing.
27.What is a negative test result? A BAC of less than 0.02.
28.What happens with a result between 0.02 and 0.039? The employee
must be removed from safety-sensitive functions for at least 24 hours
(DOT testing).
29.What happens with a result of 0.04 or greater? The employee must be
removed from safety-sensitive functions and undergo return-to-duty
procedures.
30.What does NHTSA stand for? National Highway Traffic Safety
Administration.
Testing Procedures (31-60)
31.What is the first step in the breath testing process? Verify the identity
of the individual being tested using photo ID or employer verification.
32.What documentation must a BAT check before testing? The Alcohol
Testing Form (ATF) to ensure it's complete with proper information.
33.What is the standard DOT alcohol testing form? The ATF (Alcohol
Testing Form), also known as the Breath Alcohol Testing Form.
34.How many copies does the ATF have? Typically 3-4 copies with
different distribution requirements.
35.Must the testing location provide privacy? Yes, the test must be
conducted in a location that affords privacy to the employee.
36.Can others observe the testing process? Only authorized personnel may
observe; the employee may request an observer but this cannot delay
testing.
37.What must a BAT do before beginning the test? Explain the testing
procedure to the employee and show the device serial number.
38.When should the blank test be performed? Immediately before each
individual's screening test.
