OSHA Form 300A and the February 1 Deadline
OSHA Form 300A is the annual summary of the injuries and illnesses on your OSHA 300 log. Covered employers must total the year, have a company executive certify it, and post the 300A where employees can see it from February 1 to April 30 every year, even when there were zero recordable cases. Establishments with 20 or more employees in designated industries, including construction, must also submit 300A data electronically to OSHA by March 2.
How to complete the 300A
- ✓ Total the 300 log columns: deaths, days-away cases, restricted/transfer cases, other recordables
- ✓ Total the days away and days restricted
- ✓ Break cases into injury and illness categories
- ✓ Add average employee count and total hours worked for the year (these feed rate calculations)
- ✓ A company executive (owner or officer) signs the certification
- ✓ Post it February 1 through April 30 at each establishment; keep it 5 years
Zero cases still means posting
A year with no recordable injuries still requires a completed, certified, posted 300A with zeros. Skipping the posting is one of the most common recordkeeping citations, and one of the easiest to avoid.
Your 300A feeds your TRIR
The hours and case counts on the 300A are exactly what TRIR and DART formulas use, and what prequal portals ask you to enter. Check your rates with our free TRIR calculator before a GC calculates them for you.
Common questions
▸Who must electronically submit the 300A to OSHA?
Establishments with 250 or more employees that must keep records, and establishments with 20 to 249 employees in designated high-hazard industries including construction. The submission deadline is March 2 for the prior calendar year, via OSHA’s ITA portal.
▸Do I need to post the 300A if I have fewer than 10 employees?
No. Employers with 10 or fewer employees at all times during the prior year are exempt from routine recordkeeping, including the 300A posting.
