BAT Quality Assurance Protocols 3

Question 1

What action must a BAT take if an EBT displays an 'invalid sample' or 'interference detected' message during a test?

Accepted Answer

Void the test and document the malfunction on the CCF

Answer

An 'invalid sample' message means the test cannot be evaluated; the BAT must void the test and note the reason on the Alcohol Testing Form.

Question 2

Which of the following is a required element of a Quality Assurance Plan (QAP) for EBT devices?

Accepted Answer

Inspection, maintenance, and calibration procedures

Answer

A QAP must include documented procedures for inspection, maintenance, and calibration of each EBT model used.

Question 3

An EBT's self-diagnostic check fails at the start of a test sequence. The BAT should:

Accepted Answer

Remove the device from service

Answer

A failed self-diagnostic indicates the instrument may not be functioning correctly and it must be removed from service.

Question 4

What is the purpose of the 'air blank' reading that an EBT conducts before and between breath samples?

Accepted Answer

To confirm the breath channel is free of residual alcohol

Answer

The air blank reading ensures no residual alcohol remains in the instrument's breath chamber from a previous test or environmental source.

Question 5

According to 49 CFR Part 40, what value must an air blank reading show to allow testing to continue?

Accepted Answer

0.000 g/210L

Answer

The air blank must read 0.000 g/210L; any non-zero reading requires the BAT to take corrective action before proceeding.
