Year-end is one of the best times to review your workplace injury and illness records.
If your safety records are spread across spreadsheets, emails, or paper reports, small recordkeeping mistakes can quickly turn into compliance issues.
A structured review of your OSHA 300 log can help you:
- Catch missing entries
- Verify injury classifications
- Prepare your OSHA 300A posting
- Improve internal recordkeeping for the new year
This checklist gives employers a practical way to review their logs before annual reporting deadlines.
What Is an OSHA 300 Log?
The OSHA 300 log is a record of work-related injuries and illnesses that employers must maintain if they meet OSHA recordkeeping requirements.
It documents:
- Injury dates
- Employee information
- Case descriptions
- Days away from work
- Restricted duty days
- Job transfers
The OSHA 300 log helps employers track trends and identify workplace risks.
It is also the foundation for preparing the OSHA 300A summary.

What Is the Difference Between OSHA 300 and OSHA 300A?
A common question is the difference between OSHA 300 and 300A.
Here is the simple breakdown:
OSHA 300 Log
The detailed running log of all recordable incidents.
It includes individual case-level information.
OSHA 300A Summary
The annual summary of totals from the OSHA 300 log.
It summarizes:
- Total injuries
- Total illnesses
- Days away cases
- Restricted duty cases
The 300A must be posted each year if required.
Think of it this way:
The OSHA 300 log is the full record.
The OSHA 300A is the annual summary.
Why Year-End OSHA Record Reviews Matter
A year-end review helps you identify:
- Missing incident reports
- Incorrect classifications
- Incomplete entries
- Mismatched internal records
Waiting until posting deadlines increases the risk of rushed mistakes.
A proactive review improves accuracy and makes annual reporting easier.

OSHA 300 Log Year-End Checklist
Use this checklist to review your records.
Answer each question:
- Yes
- No
- Not sure
Make notes as you go.
1. Are all recordable incidents included?
Review:
- Incident reports
- Workers’ compensation records
- HR reports
- Supervisor reports
Compare them against your OSHA 300 log.
Missing incidents create inaccurate reporting.
Duplicate entries create inflated totals.
Both should be corrected.
2. Are your entries complete?
Review each line.
Check for:
- Incident dates
- Job titles
- Injury descriptions
- Classification accuracy
- Days away from work
- Restricted duty days
Incomplete entries create reporting gaps.
Make corrections now.
3. Are injury classifications accurate?
Not every workplace incident is recordable.
Review whether each entry is properly classified.
Examples:
- Days away from work
- Restricted duty
- Medical treatment beyond first aid
Classification errors are common.
If uncertain, review OSHA guidance.
4. Does your OSHA 300 log match your OSHA 301 reports?
Your OSHA 301 forms (or equivalent incident reports) should support your OSHA 300 log.
Compare:
- Incident dates
- Employee names
- Injury descriptions
- Corrective actions
If records do not align, investigate.
Consistency matters.
5. Is your OSHA 300A ready?
Your OSHA 300A depends on your OSHA 300 log totals.
Before finalizing:
- Verify totals
- Check calculations
- Confirm annual summary accuracy
Errors in the log carry into the summary.
Fix the source first.
6. Have you reviewed trends?
Your OSHA 300 log is not just for compliance.
It is also a valuable safety tool.
Look for patterns:
- Repeat injuries
- Specific departments
- High-risk tasks
- Frequent causes
Patterns help guide safety improvements.
7. Is your team trained on recordkeeping?
Good recordkeeping depends on training.
Supervisors and managers should understand:
- What must be reported
- What is recordable
- Documentation timelines
- Internal reporting procedures
This is where OSHA recordkeeping training becomes important.
Training reduces mistakes.
