Turn your OSHA 300 totals and hours worked into the standard safety incident rates — TRIR / TCIR, DART rate, lost-time case rate, severity rate and the international LTIFR — each shown with its exact formula. Add multiple years to see your trend and compare against the BLS industry benchmark. Free; exports to Word and CSV.
All recordable injuries & illnesses (300 log entries).
Days Away, Restricted or Transferred (a subset of recordables).
Cases with one or more days away from work (DAFW).
Calendar days away (and restricted, if you track them) — for severity.
Actual hours worked in the period (do not include leave).
If hours are unknown, fill these two and we estimate hours = employees × average hours.
Add several years to chart your TRIR over time. Edit any cell, then re-chart.
| Year | Recordables | DART | Lost-time | Days lost | Hours | TRIR | DART rate | LTIFR |

⚠️ These rates are only as accurate as your inputs. They depend on correct recordability determinations under OSHA recordkeeping (29 CFR 1904) and on accurate hours worked — count actual hours worked, not paid leave. This tool gives the arithmetic; it is not legal advice and is not an official OSHA or BLS document. Benchmarks shown are general; always compare against your own NAICS industry average published by the U.S. Bureau of Labor Statistics (BLS), and against your local regulator's expectations.
