Understanding OSHA 300 Logs
If you manage workplace safety, you’ve likely encountered OSHA’s recordkeeping requirements. OSHA 300 logs are crucial documents used to track work-related injuries and illnesses. But one of the most common compliance questions is: How long do you have to keep OSHA 300 logs?
The short answer: five years.
OSHA’s Retention Requirements
According to OSHA regulation 29 CFR § 1904.33, employers must keep the following records for at least five years after the end of the calendar year they cover:
-
OSHA 300 Log – A running log of all recordable workplace injuries and illnesses.
-
OSHA 301 Incident Report (or equivalent) – A detailed incident report for each case.
-
OSHA 300A Summary – An annual summary of all cases from the OSHA 300 Log.
Important Notes:
-
Employers must update the OSHA 300 Log during the 5-year retention period if they discover new information or if an outcome changes (for example, if a worker’s condition worsens).
-
The OSHA 300A Summary must be posted at the workplace from February 1 through April 30 each year, but it still needs to be kept on file for five years.
-
OSHA 301 forms don’t need to be updated after they’re completed, but they must also be retained.
Why Retention Matters
Failing to maintain OSHA logs for the required period can lead to hefty fines and citations. Beyond compliance, accurate recordkeeping also helps employers:
-
Track workplace safety trends
-
Identify recurring hazards
-
Build a safer work environment
-
Protect the organization in case of audits or legal issues
Final Answer: How Long to Keep OSHA 300 Logs
You must keep OSHA 300 logs, OSHA 300A summaries, and OSHA 301 reports for five years after the year they cover. During that time, you must keep the OSHA 300 Log up-to-date with any new or revised information.
By following these rules, you’ll stay compliant and ensure your workplace safety documentation is ready if OSHA comes knocking.
Pro Tip: Simplify Recordkeeping
Managing OSHA logs manually can be time-consuming and prone to errors. To make compliance easier, consider using OSHA recordkeeping software. These tools help you track incidents, generate required forms, and maintain records for the full retention period—all while reducing administrative headaches.
