TRIR calculator
Total recordable incident rate: how many recordable incidents your company had per 100 full-time workers. Enter two numbers — the result updates as you type.
200,000 is the hours 100 full-time employees work in a year (40-hour weeks × 50 weeks). It normalises your incident count so companies of any size can be compared.
How to read your TRIR
TRIR counts recordable incidents — work-related injuries and illnesses beyond simple first aid — normalised per 100 full-time workers, so a 12-person workshop and a 1,200-person plant can be compared on the same scale.
A single number never tells the whole story. Three things to keep in mind:
- Sector averages differ widely — construction and manufacturing run higher than offices. Compare against your own industry, not the all-industry average.
- Your trend beats the absolute number. A falling TRIR over several quarters says more than any single reading.
- TRIR is a lagging indicator — it measures what already went wrong. Pair it with leading indicators like near-miss reports, inspections and training coverage.
Counting starts with reporting. A simple incident report template makes sure every event gets recorded the same way.
Track incidents, not spreadsheets
OHS computes your TRIR continuously from real incident records — every report updates the number, no year-end spreadsheet archaeology.
