Lost Time Incident Rate (LTIR)

The Lost Time Incident Rate (LTIR) is a safety measurement used to track the number of work-related injuries that result in employees missing days from work. It is calculated by multiplying the number of lost-time injuries by 1,000,000, then dividing that by the total number of hours worked by all employees during a specific period. LTIR helps organizations assess safety performance, identify trends, and implement improvements. A lower LTIR indicates a safer work environment with fewer serious injuries leading to time off.
