Alabama Administrative Code › Title 370 - Alabama Department of Forensic Sciences › Chapter 370-1-1 - CHEMICAL TEST FOR INTOXICATION › Appendix A - EVIDENTIAL BREATH ALCOHOL TESTING QUALITY CONTROL

Current through Register Vol. 42, No. 9, June 28, 2024
Purpose.
The purpose of this section is to inform the public
				of the quality control or good laboratory practices that are utilized
				by the Alabama Department of Forensic Sciences to support Breath
				Alcohol Testing in the field. The practices described in this section
				only demonstrate that each Draeger Alcotest 7110 MKIII is capable of
				performing as expected. The method as described in
				370-1-1-.01(4) is the only sequence of steps that isolates alcohol (ethanol) from a
				subject to accurately determine the amount. Subsequently the quality
				control built into the method is the only process that verifies a
				particular Breath Alcohol Test did indeed perform as expected. Since
				the authority derived from §
								32-5A-194 Code of Ala. 1975, as amended, is limited to a method to perform a
				chemical analysis to determine the alcoholic content of a subjects
				blood the following information pertaining to good laboratory
				practice
does not constitute a rule.
(1) Pre-installation Evaluation. Each Draeger
				Alcotest 7110 MKIII is evaluated by the Alabama Department of
				Forensic Sciences Technical Director or his designee prior to being
				placed in operation. The evaluation will demonstrate the ability of
				each Draeger Alcotest 7110 MKIII to identify and flag specific
				conditions; as well as, verify the analytical integrity of the
				instrument.
(a)
Purging Error.
Place the
				instrument in the "Error Check" mode. Restrict the air flow into the
				ambient air inlet while the pump is running. This will prompt the
				instrument to display "Check Sampling Hose" and sound an audible
				alarm. Record pass if the message "Error Triggered, Test Okay" is
				printed. If the error is not triggered initiate the necessary
				corrective actions to restore the instrument to proper working
				condition.
(b)
Minimum Volume Not Achieved.
Place the instrument in the "Error Check" mode. At the prompt "Please
				Blow", deliver a deficient sample volume. Record pass if the message
				"Error Triggered, Test Okay" is printed. If the error is not
				triggered initiate the necessary corrective actions to restore the
				instrument to proper working condition.
(c)
Blowing Time Too Short.
Place
				the instrument in the "Error Check" mode. At the prompt "Please
				Blow", deliver a sample of sufficient volume and deficient duration.
				Record pass if the message "Error Triggered, Test Okay" is printed.
				If the error is not triggered initiate the necessary corrective
				actions to restore the instrument to proper working condition.
(d)
Blowing Not Allowed.
Place the
				instrument in the "Error Check" mode. At any time other than when the
				instrument indicates "Please Blow" deliver a sample into the
				instrument. Record pass if the message "Error Triggered, Test Okay"
