In investigating possible violations of section 3702.14 of the Revised Code, or in conducting hearings under section 3702.20 of the Revised Code, the director of health may administer oaths, order the taking of depositions, and issue subpoenas compelling attendance of witnesses or production of documents. The subpoenas shall be served in the same manner as subpoenas and subpoenas duces tecum issued for a trial of a civil action in a court of common pleas. If a person served a subpoena fails to attend a hearing or produce documents or refuses to be sworn or to answer any question, the director may apply to the court of common pleas of the county in which the person resides, or the county in which the hearing under section 3702.20 of the Revised Code is conducted, for a contempt order, as in the case of a failure of a person who is served a subpoena issued by the court to attend or produce documents or a refusal of such person to testify.
