Lost Time Injury Frequency RateLTIFR
Lost-time injuries per million hours worked.
LTIFR = (number of LTIs × 1,000,000) ÷ hours worked. Common in Australia, the UK, and global mining/construction benchmarking. US equivalents normalise to 200,000 hours (100 workers × 2,000 hrs). An LTI is any work-related injury causing at least one full shift of lost time.
