Ohio Rev. Code § 3791.06
No person shall employ or direct another to do or perform labor in erecting, repairing, altering, or painting a house, building, or other structure, and knowingly or negligently furnish, erect, or cause to be furnished for erection for and in the performance of said labor, unsuitable or improper scaffolding, hoists, stays, ladders, or other mechanical contrivances which will not give proper protection to the life and limb of a person so employed or engaged.
Whoever violates this section shall be fined not more than five hundred dollars or imprisoned not more than three months, or both.
If such scaffolding, swung or suspended from an overhead support or supports, is more than twenty feet from the ground floor, it is not deemed to give proper protection to the life and limb of persons employed or engaged on such scaffolding unless, when in use, it has a safety rail rising at least thirty-four inches above the floor or main portion extending along the outside thereof, and properly attached thereto, and is provided with braces strong enough to sustain the weight of a man's body against it and to prevent such scaffolding from swaying from the building or structure.
