Reviewed June 2026 by Enterprise Health

Key facts

  • Form 300 (log), 300A (annual summary), 301 (incident report)
  • Required for employers with 10+ employees in covered industries
  • 300A summary posted Feb 1–Apr 30 each year
  • Records retained for five years

What it means

Form 300 (the Log of Work-Related Injuries and Illnesses), its 300A annual summary, and the 301 incident report are the backbone of OSHA injury recordkeeping. Employers with more than 10 employees in covered industries must maintain them, post the 300A each year, and retain records for five years. Driving the log directly from clinical encounters eliminates the parallel spreadsheet most teams keep.

Frequently asked

Who has to keep an OSHA 300 Log?

Employers with more than 10 employees in covered industries must maintain the 300 Log, post the 300A annual summary each year, and retain the records for five years. Some low-hazard industries are partially exempt.

What's the difference between Forms 300, 300A and 301?

The 300 is the running log of recordable injuries and illnesses, the 300A is the annual summary that's posted, and the 301 is the individual incident report. Driving them from clinical encounters removes the parallel spreadsheet.
