Total Recordable Injury Frequency Rate (TRIFR) is a key safety metric that measures the number of recordable injuries per 1,000,000 hours worked.
It helps organizations track safety performance, identify trends, and benchmark against industry standards. TRIFR includes all recordable injuries, not just lost-time injuries.
