Ohio Rev. Code § 1565.02: Mine foreman - duties - delegation of duties.

Under the direction of the superintendent in charge of a mine, the mine foreman shall carry out this chapter and Chapters 1561., 1563., and 1567. of the Revised Code, see that the regulations prescribed for each class of workmen under his charge are carried out, and see that any deviations from any of them are promptly adjusted. This section does not prohibit the mine foreman from delegating any of his duties, except those which are subject to the limitations of such chapters, to men who in his judgment are competent to perform them, but such delegation shall not relieve the mine foreman from the responsibility of having these duties properly performed.

No person shall refuse or neglect to comply with this section.
