Lost Time Injury Rate (LTIR)
Lost Time Injury Rate (LTIR) measures workplace safety by calculating the number of injuries that result in an employee missing work, relative to total hours worked. It is expressed as a ratio, usually per one million hours worked. A lower LTIR indicates a safer work environment, showing fewer injuries leading to time off. This metric helps organizations track safety performance over time, identify trends, and implement improvements to protect workers and reduce downtime caused by injuries.
