Ohio Revised Code Title XXXVII. Health Safety Morals § 3742.17

(A) Where any person is licensed by the department of health to engage in lead abatement, lead inspection, lead risk assessment, clearance examination, or any other activity under this chapter, the liability of that person, when performing the activity in accordance with procedures established pursuant to state or federal law, for an injury to any individual or property caused or related to the activity shall be limited to acts or omissions of the person during the course of performing the activity that can be shown, based on a preponderance of the evidence, to have been negligent. For the purposes of this section, the demonstration that acts or omissions of a person performing lead abatement, lead inspection, lead risk assessment, clearance examination, or other activities under this chapter were in accordance with generally accepted practice and with procedures established by state or federal law at the time the abatement, inspection, assessment, examination, or other activity was performed creates a rebuttable presumption that the acts or omissions were not negligent.

(B) Where any person contracts with a person licensed as a lead inspector, lead abatement contractor, lead risk assessor, lead abatement project designer, lead abatement worker, or clearance technician the liability of that person for lead-related injuries caused by the person's contractee in the performance of lead abatement, lead inspection, lead risk assessment, clearance examination, or other activities under this chapter shall be limited to those lead-related injuries arising from acts or omissions that the person knew, or could reasonably have been expected to know, were not in accordance with generally accepted practices or with procedures established by state or federal law at the time the activity took place.

(C) Notwithstanding any other provisions of the Revised Code or rules of a court to the contrary, this section governs all claims for lead-related injuries to individuals or property arising from lead abatement, lead inspection, lead risk assessment, clearance examination, or other activities for which a license is required under this chapter.
