Ohio Rev. Code § 4123.02: Policemen and firemen excepted.

This chapter does not apply to policemen or firemen in municipal corporations where the injured policemen or firemen are eligible to participate in any policemen's or firemen's pension funds established and maintained by a municipal corporation, unless the amount of the pension funds provided by the municipal corporation through taxation and paid to the policemen or firemen is less than they would have received if the municipal corporation had no pension fund. In such event policemen and firemen shall receive the regular state compensation for policemen and firemen in municipal corporations where no pension funds have been created, less the sum received by the policemen or firemen from the pension funds provided by the municipal corporation through taxation. The sum paid from the pension fund shall be certified to the bureau of workers' compensation by the treasurer or other officer controlling the pension fund.
