Ohio Revised Code Title XV. Conservation of Natural Resources § 1565.11

The miners employed in a mine may appoint two of their number to act as a safety committee to inspect, not more often than once each month, the mine and the machinery connected therewith, and to measure the ventilating current. The operator may accompany such committee, or appoint two or more persons for that purpose. The operator shall afford every necessary facility for making such inspection and measurement, but the committee shall not interrupt or impede the work in the mine, at the time of such inspection and measurement. After such inspection and measurement, such committee shall forthwith make a report thereof to the chief of the division of mineral resources management, on a blank furnished by the chief.

No operator of a mine shall refuse or neglect to comply with this section, and no such person shall violate this section.
