Ohio Code § 4123.28

§ 4123.28.

Every employer in this state shall keep a record of all injuries and occupational

diseases, fatal or otherwise, received or contracted by his employees in the course

of their employment and resulting in seven days or more of total disability.  Within a week after acquiring knowledge of an injury or death therefrom, and in

the event of occupational disease or death therefrom, within one week after acquiring

knowledge of or diagnosis of or death from an occupational disease or of a report

to the employer of the occupational disease or death, a report thereof shall be made

in writing to the bureau of workers' compensation upon blanks to be procured from

the bureau for that purpose.  The report shall state the name and nature of the business of the employer, the

location of his establishment or place of work, the name, address, nature and duration

of occupation of the injured, disabled, or deceased employee and the time, the nature,

and the cause of injury, occupational disease, or death, and such other information

as is required by the bureau. The employer shall give a copy of each report to the employee it concerns or his surviving

dependents. No employer shall refuse or neglect to make any report required by this section. Each day that an employer fails to file a report required by this section constitutes

an additional day within the time period given to a claimant by the applicable statute

of limitations for the filing of a claim based on the injury or occupational disease,

provided that a failure to file a report shall not extend the applicable statute of

limitations for more than two additional years.
