The Lost Time Injury Rate (LTIR) is a key safety metric used to measure workplace injuries. It calculates the number of lost time injuries per one million hours worked. A lost time injury is defined as an incident that results in an employee being unable to perform their regular work duties for at least one full shift. LTIR helps organizations assess their safety performance and identify areas for improvement. By tracking this rate, companies can implement better safety protocols and training programs, ultimately aiming to reduce workplace accidents and enhance employee well-being.
