OSHA 300 vs. 301 vs. 300A: What Is the Difference?
The OSHA 301 is the individual incident record, the OSHA 300 is the running log of recordable cases, and the OSHA 300A is the annual summary. Arkvos connects those records in one employer workflow.
OSHA 301
Detailed information about one injury or illness case, including the employee, event and treatment details.
OSHA 300
The establishment's running log of confirmed recordable injuries and illnesses for the year.
OSHA 300A
The annual summary of the OSHA 300 log, including case totals and employment information required for the summary.
Arkvos connection
A supervisor-reported incident can move through corporate review and then feed the 300 and 300A workflow when the employer confirms it is recordable.
Frequently asked questions
Do workers need Arkvos accounts for OSHA recordkeeping?
No. The Arkvos OSHA Recordkeeping Center is an employer-side workflow. Supervisors can report incidents and authorized owners/admins can review recordability and annual records.
Does Arkvos decide whether a case is legally recordable?
No. Arkvos can surface recordability criteria as decision support, but the employer remains responsible for making and confirming the legal recordkeeping decision under applicable federal or State Plan rules.
Does Arkvos replace legal or safety advice?
No. Arkvos organizes records and workflow. Employers should review current OSHA and State Plan requirements and use qualified safety or legal advice when needed.

Factual anchors and primary sources
Arkvos separates product capabilities from regulatory requirements. For federal OSHA requirements, the primary authority is OSHA's current regulations and guidance. California construction employers should also review the applicable Cal/OSHA Title 8 requirements.
- OSHA regulations and standards
- OSHA recordkeeping resources
- OSHA 29 CFR 1904.33 retention and updating
- OSHA 2026 civil penalties memorandum
- Cal/OSHA Title 8 §1509
OSHA 29 CFR 1904.33 requires the OSHA 300 Log, annual summary, OSHA 301 Incident Report forms, and privacy case list if one exists to be retained for five years after the end of the calendar year they cover. Cal/OSHA Title 8 §1509(e) requires construction supervisors to conduct toolbox or tailgate safety meetings, or equivalent, with crews at least every 10 working days. Requirements vary by jurisdiction and work activity, so employers should verify the rule that applies to their facts.
