What it means
The 300A is the annual summary of the OSHA 300 Log. It shows the year's totals for each case type, plus the average number of employees and the hours worked.
A company official reviews and certifies it. Employers generally have to make it available to employees. A site with zero cases still fills one out.
Posting dates, how long to keep it, who must file it electronically, and who's exempt all depend on the current rule. Check the OSHA recordkeeping rules, OSHA 29 CFR 1904, before you act.
Why it matters
The 300A is where the year's totals land in one place, and it's the page employees and inspectors read. The same hours and case counts feed your TRIR, so errors here show up in your rates.
What it looks like on a site
- After year end, the safety lead checks the 300 Log for missing cases and wrong dates.
- The lead totals each case type and gets the hours figure from payroll.
- A company official reviews and signs it.
- The lead posts it where employees can see it, using the current rule for dates and locations.
- A copy goes in the file for the retention period your current rules require.
