Ohio Rev. Code § 161.07
At the time of their designation, emergency interim successors shall take such oath as may be required for them to exercise the powers and discharge the duties of the office to which they may succeed. Notwithstanding any other provision of law, no person, as a prerequisite to the exercise of the powers or discharge of the duties of an office to which he succeeds, shall be required to comply with any other provision of law relative to taking office.
Until such time as the persons designated as emergency interim successors are authorized to exercise the powers and discharge the duties of an office in accordance with this section, such persons shall serve in their designated capacities at the pleasure of the designating authority and may be removed or replaced by said designating authority at any time, with or without cause.
