Understanding the OSHA 300 Log Report and the OSHA 300A Summary Report

Use the OSHA 300 Log report to classify and report work-related injuries and illnesses, including what happened, how it happened, and the severity and extent for each case.

Use the OSHA 300A Summary report to total the detailed case information for each establishment for each calendar year. Employers must post the summary from the previous year in a place where workers can view the report.
