What is TRIR?
TRIR is the Total Recordable Incident Rate. It normalizes recordable work-related cases to a 200,000-hour base so safety performance can be compared consistently.

FORMULA
TRIR = (Recordable Cases × 200,000)
÷ Total Hours Worked
÷ Total Hours Worked
The 200,000-hour base represents 100 full-time employees working 40 hours per week for 50 weeks.
⚠
IMPORTANT
Use consistent case classification and verified working-hour data when comparing performance across periods or locations.
TRIR KNOWLEDGE GUIDE
Understand what the result means
TRIR is more than a number. Correct interpretation requires understanding recordability, hours worked, the 200,000-hour normalization and appropriate comparison methods.

Why 200,000?
200,000 hours is the standard normalization base representing roughly 100 full-time employees working about 2,000 hours each per year.

Which Cases Count?
Under OSHA recordkeeping, work-related cases involving death, days away, restricted work or job transfer, and certain medical treatment may be recordable.

How to Interpret It?
TRIR should not be judged as good or bad in isolation. Compare it with the same industry, location, reporting period and historical performance.
