OSHA 300 Log Program

The regulation that requires it in Illinois

Federal OSHA requires employers to record work-related injuries and illnesses on the OSHA 300 Log, 300A Annual Summary, and 301 Incident Report. Illinois follows the federal OSHA plan, so the applicable rule is 29 CFR 1904.1-1904.41. Illinois does not operate an approved state OSHA plan for private employers.

Enforcing agency

Federal OSHA — Region V (IL OSHA covers public-sector employers) enforces the recordkeeping requirements. Inspectors review logs during workplace inspections and may issue citations for violations. Federal OSHA retains oversight authority; the state agency handles only public-sector employers.
