This guide walks small employers through OSHA injury and illness recordkeeping at a practical level: decide what is recordable, fill Forms 300/301, post the 300A summary, and prepare for electronic ITA submission when required.
1. Confirm you must keep records
Many employers with more than 10 employees must keep Part 1904 records unless a partial exemption applies. Confirm your status using current OSHA guidance for your size and industry.
2. Decide recordability quickly and consistently
Capture the event facts the same day when possible. Use a shared definition of medical treatment beyond first aid so supervisors are not inventing rules under pressure. See recordable injury.
3. Complete Form 301 and Form 300
Form 301 (Incident Report) holds case detail. Form 300 is the annual log. Keep case numbers aligned. Download our free 300 log template.
4. Post Form 300A and watch ITA deadlines
The annual summary (300A) is typically posted February 1–April 30. Covered establishments may also need to submit 300A data electronically—use the ITA deadline checker.
