What is TRIR?
Total Recordable Incident Rate (TRIR) is a workplace safety performance indicator used to measure the number of recordable injuries and illnesses per 200,000 hours worked.
TRIR Formula
TRIR = (Number of Recordable Incidents × 200,000) ÷ Total Hours WorkedExample Calculation
A company recorded:
- Recordable incidents: 4
- Total hours worked: 400,000
Calculation:
(4 × 200,000) ÷ 400,000
TRIR = 2.00TRIR vs LTIFR
