Ohio Rev. Code § 4123.51
The administrator of workers' compensation shall by published notices and other appropriate means endeavor to cause claims to be filed in the service office of the bureau of workers' compensation from which the investigation and determination of the claim may be made most expeditiously. A claim or appeal under this chapter or Chapter 4121., 4127., or 4131. of the Revised Code may be filed with any office of the bureau of workers' compensation or the industrial commission, within the required statutory period, and is considered received for the purpose of processing the claims or appeals.
The administrator, on the form an employee or an individual acting on behalf of the employee files with the administrator or a self-insuring employer to initiate a claim under this chapter or Chapter 4121., 4127., or 4131. of the Revised Code, shall include a statement that is substantially similar to the following statement in bold font and set apart from all other text in the form:
"By signing this form, I elect to only receive compensation, benefits, or both that are provided for in this claim under Ohio's workers' compensation laws. I understand and I hereby waive and release my right to receive compensation and benefits under the workers' compensation laws of another state for the injury or occupational disease, or the death resulting from an injury or occupational disease, for which I am filing this claim. I have not received compensation and benefits under the workers' compensation laws of another state for this claim, and I will not file and have not filed a claim in another state for the injury or occupational disease or death resulting from an injury or occupational disease for which I am filing this claim."
