Ohio Revised Code Title XV. Conservation of Natural Resources § 1503.18

(A) No person shall kindle a fire upon public land without the written permission of the forest-fire warden having jurisdiction or on land of another without the written permission of the owner or the owner's agent.

(B) No person shall kindle or authorize another to kindle a fire in or near any woodland, brushland, or land containing tree growth or in any place from which the fire is likely to escape unless all leaves, grass, wood, and inflammable material surrounding the place where the fire is kindled have first been removed to a safe distance and all other reasonable precautions have been taken to prevent its escape from control. No fire shall be left until extinguished or safely covered.

(C) Excepting fires kindled in a plowed field, garden, or public highway at a distance of not less than two hundred feet from any woodland, brushland, or field containing dry grass or other inflammable material, no person shall kindle or authorize another to kindle a fire in the open air, outside the limits of any municipal corporation or land controlled by any railroad company, for the purpose of burning wood, brush, weeds, grass, or rubbish of any kind between the hours of six a.m. and six p.m. during the months of March, April, May, October, and November in any year. The chief of the division of forestry may adopt rules in accordance with Chapter 119. of the Revised Code to expand the times and places for kindling fires for any affected persons.

(D) The times and places for kindling fires established under division (C) of this section may be restricted or eliminated by executive order of the governor if environmental conditions so warrant.

(E) Fires kindled by improperly disposing of a lighted match, cigar, or other burning or glowing substance are kindled fires within the meaning of this section.
