Two focused tools for the questions that come before a recordkeeping workflow. Calculate TRIR and DART from your hours and cases, or check the federal size and industry branches that shape an OSHA 300 review.
No account, email capture, or saved inputs. Use the result with the official sources linked on each page.
Each tool stays deliberately narrow. It gives you a visible result, shows the basis behind it, and points you to the federal source that deserves the final read.
Calculate the two rates teams most often review alongside Form 300A. Enter the hours and case counts you already have, then see both results to two decimal places.
Use the prior-year company-wide size test and an establishment-specific Appendix A reference to get a cautious starting point for your next coverage review.
Independent software, practical starting points. FORM 300 LOGBOOK is not affiliated with OSHA or the U.S. Department of Labor. The tools do not provide legal advice, make a filing, decide recordability, or determine state-plan requirements. Read the broader Recordkeeping Guidance
Once the question is clear, FORM 300 LOGBOOK gives small businesses one private place to connect Forms 300, 301, and 300A, review the year, and keep exports together for their own review.
Review the product path when a calculator or coverage check points you toward a more organized recordkeeping process.
