Ohio Rev. Code Ann. § 5104.25 – Prohibiting smoking

(A) Except as otherwise provided in division (C) of this section, no child day-care center shall permit any person to smoke in any indoor or outdoor space that is part of the center. The administrator of a child day-care center shall post in a conspicuous place at the main entrance of the center a notice stating that smoking is prohibited in any indoor or outdoor space that is part of the center, except under the conditions described in division (C) of this section.
(B) Except as otherwise provided in division (C) of this section, no type A family day-care home or licensed type B family day-care home shall permit any person to smoke in any indoor or outdoor space that is part of the home during the hours the home is in operation. Smoking may be permitted during hours other than the hours of operation if the administrator of the home has provided to a parent, custodian, or guardian of each child receiving child care at the home notice that smoking occurs or may occur at the home when it is not in operation. The administrator of a type A family day-care home or a licensed type B family day-care home shall post in a conspicuous place at the main entrance of the home a notice specifying the hours the home is in operation and stating that smoking is prohibited during those hours in any indoor or outdoor space that is part of the home, except under the conditions described in division (C) of this section.
(C) A child day-care center, type A family day-care home, or licensed type B family home may allow persons to smoke at the center or home during its hours of operation if those persons cannot be seen smoking by the children being cared for and if they smoke in either of the following:
1. (1) An indoor area that is separately ventilated from the rest of the center or home;
2. (2) An outdoor area that is so far removed from the children being cared for that they cannot inhale any smoke.
(D) The director of job and family services, in consultation with the director of health, shall adopt rules in accordance with Chapter 119. of the Revised Code to implement the requirements of this section. These rules may prohibit smoking in a child day-care center, type A family day-care home, or licensed type B family home if its design and structure do not allow persons to smoke under the conditions described in division (C) of this section or if repeated violations of division (A) or (B) of this section have occurred there.
