Ohio Revised Code Title XV. Conservation of Natural Resources § 1561.34

If a deputy mine inspector finds danger of an imminent and extraordinary character in any mine, the deputy mine inspector shall immediately take steps to safeguard the employees, notify the superintendent, the mine foreperson, or any other person in charge of employees at once of the condition the deputy mine inspector has found, and require them to exercise their authority to remedy the situation; in all such instances, the deputy mine inspector shall stop all workings in the particular section in which the deputy mine inspector found the dangerous condition, or the entire mine if necessary, until the condition found is remedied. Before leaving the mine property, the deputy mine inspector shall make a report in writing setting forth clearly the dangerous conditions of imminent and extraordinary character found, the steps taken by the deputy mine inspector to safeguard the employees, and confirming the orders or instructions given to the superintendent, mine foreperson, or other person in charge of employees. The deputy mine inspector shall make this report in quadruplicate or quintuplicate, sending the original at once to the chief of the division of mineral resources management, giving a copy to the mine superintendent, posting one on the bulletin board of the mine, and retaining a copy for the deputy mine inspector's files. Where the miners have a mine safety committee, the deputy mine inspector shall post one additional copy on the mine bulletin board for the use and possession of the committee. This report shall be known as the deputy mine inspector's emergency report.
