than an EBT, that is approved by the
National Highway Traffic Safety
Administration (NHTSA) and placed on a
conforming products list (CPL) for such
devices. At the time of publication, the CPL
had 16 testing devices that had been
approved as ASDs. Two of these were
saliva tests and 14 were non-evidential
breath tests.
ASDs may only be operated by trained
and qualified Screen Test Technicians
(STT). Only ASDs on the NHTSA
conforming products lists that have
instructions for them included in Part 40
may be used to conduct DOT alcohol
screening tests (§40.229). An ASD can only
be used for a screen test and may not be
used for a confirmatory test.
Evidential Breath Testing Device
(EBT) (§40.231). An EBT is a device that
measures an employee’s alcohol
concentration. It must be able to distinguish
alcohol from acetone at the 0.02 alcohol
concentration level. EBTs must be capable
of conducting air blank tests and external
calibration checks, and they must be
approved by NHTSA and operated by
qualified and trained Breath Alcohol
Technicians.
The Conforming Products List (CPL) of
EBT devices that was current as of the date
of this document’s publication is provided in
the Sample Documentation section of this
chapter. When viewing the CPL, special
note should be made that only those devices
listed without an asterisk (*) are authorized
for use in confirmatory alcohol testing under
the DOT alcohol testing program. NHTSA
will occasionally print updates to their CPL
of EBTs in the Federal Register. This list
can be found at: http://www.nhtsa.dot.gov
/people/injury/alcohol/ebtcpl021003FR.pdf.
For confirmation tests, EBTs must be
able to:
• Print each test result in triplicate or
three consecutive identical copies;
• Assign a unique number to each
completed test, allow the BAT and
the employee to read the number
before each test, and print the
number on each copy of the result;
• Print on each copy of the result the
manufacturer’s name for the device,
the device’s serial number, and the
time of the test;
• Distinguish alcohol from acetone at
the 0.02 alcohol concentration level;
• Test air blanks; and
• Perform external calibration checks.
Each EBT device must have a
manufacturer-developed quality assurance
plan approved by NHTSA (§40.233). The
plan must include the following:
• A designated method or methods to
perform external calibration checks
of the device;
