What Is OSHA Form 300A?
The annual Summary of Work-Related Injuries and Illnesses: what it contains, who signs, and when to post.
Quick definition
OSHA Form 300A is the Summary of Work-Related Injuries and Illnesses. Form 300A is the annual summary, not the running Form 300 log and not a downloadable substitute for OSHA's current official forms. It totals the cases from your Form 300 log for the calendar year, along with the establishment's annual average number of employees and total hours worked.
Key requirements
1. Complete it every year if you are covered by OSHA's recordkeeping rule, even if you had zero recordable cases (enter zeros).
2. Certify it. A company executive must review and certify that the totals are correct.
3. Post it in a visible workplace location from February 1 through April 30 of the following year.
4. Keep it for five years after the end of the year it covers.
5. Submit electronically through the ITA if your establishment is covered, generally by March 2.
What is on the form
Totals for deaths, days away from work cases, job transfer or restriction cases, and other recordable cases; total days away and days of restriction; counts by injury or illness type; plus the establishment's name, location, NAICS code, annual average employees, and hours worked.
300 vs 300A vs 301
The 300 is the running log of cases. The 301 is the detailed incident report for each case. The 300A is the year-end summary. Use our free OSHA 300 log template for the log, and see the worked OSHA 300 example for how to fill it in. Rivkor generates 300, 300A, and 301 from incident records so the summary always reconciles with the log.
