Rule 3701-53-04 | Instrument checks, controls and certifications.
(A) A senior operator shall perform an instrument check on approved evidential breath testing instruments listed under paragraphs (A)(1), (A)(2), and (B) of rule 3701-53-02 no less frequently than once every seven days in accordance with the appropriate instrument checklist for the instrument being used. The instrument check may be performed anytime up to one hundred and ninety-two hours after the last instrument check.
(1) The instrument shall be checked to detect radio frequency interference (RFI) using a hand-held radio normally used by the law enforcement agency performing the instrument check. The RFI detector check is valid when the evidential breath testing instrument detects RFI or aborts a subject test. If the RFI detector check is not valid, the instrument shall not be used until the instrument is serviced.
(2) An instrument shall be checked using a solution containing ethyl alcohol approved by the director of health. An instrument check result is valid when the result of the instrument check is at or within five one-thousandths (0.005) grams per two hundred ten liters of the target value for that approved solution. An instrument check result which is outside the range specified in this paragraph shall be confirmed by the senior operator using another bottle of approved solution. If this instrument check result is also out of range, the instrument shall not be used until the instrument is serviced or repaired.
(B) Instruments listed under paragraph (A)(3) of rule 3701-53-02 of the Administrative Code shall automatically perform a dry gas control using a dry gas standard traceable to the national institute of standards and technology (NIST) before and after every subject test. For purposes of an instrument listed under paragraph (A)(3) of rule 3701-53-02 of the Administrative Code, a subject test shall include the collection of two breath samples. A dry gas control is not required between the two breath samples. Dry gas control results are valid when the results are at or within five one-thousandths (0.005) grams per two hundred ten liters of the alcohol concentration on the manufacturer's certificate of analysis for that dry gas standard. A dry gas control result which is outside the range specified in this paragraph will abort the subject test or instrument certification in progress.
(C) Representatives of the director shall perform an instrument certification on approved evidential breath testing instruments listed under paragraph (A)(3) of rule 3701-53-02 of the Administrative Code using a solution containing ethyl alcohol approved by the director of health according to the instrument display for the instrument being certified. A dry gas control using a dry gas standard traceable to the national institute of standards and technology (NIST) shall also be used when a certification is performed. An instrument shall be certified no less frequently than once every calendar year or when the dry gas standard on the instrument is replaced, whichever comes first. A calendar year means the period of twelve consecutive months, as indicated in section 1.44 of the Revised Code, beginning on the first day of January, and ending on the thirty-first day of December. Instrument certifications are valid when the certification results are at or within five one-thousandths grams per two hundred ten liters of the target value for that approved solution. Instruments with certification results outside the range specified in this paragraph will require the instrument be removed from service until the instrument is serviced or repaired. Certification results shall be retained in a manner prescribed by the director of health.
(D) An instrument check or certification shall be made in accordance with paragraphs (A) and (C) of this rule before a new evidential breath testing instrument is placed in service or before the instrument is placed into service following repairs, before the instrument is used to test subjects.
(E) A bottle of approved solution containing ethyl alcohol shall not be used more than three months after its date of first use, or after the manufacturer's expiration date on the approved solution certificate, whichever comes first. After first use, a bottle of approved solution shall be kept under refrigeration when not being used. The approved solution bottle shall be retained for reference until that bottle of approved solution is discarded.
(F) Each testing day, the analytical techniques or methods used in rule 3701-53-03 of the Administrative Code shall be checked for proper calibration under the general direction of the designated laboratory director. General direction does not mean that the designated laboratory director must be physically present during the performance of the calibration check.
(G) Results of instrument checks, controls, certifications, calibration checks and records of service and repairs shall be retained in accordance with paragraph (A) of rule 3701-53-01 of the Administrative Code.
