LTI stands for Lost Time Injury, a common safety metric in workplaces.

• LTI is a safety metric used to track the number of work-related injuries that result in lost work days.

• The formula to calculate LTI is (Number of Lost Time Injuries / Total Hours Worked) x 1,000,000.

• For example, if a company had 5 lost time injuries in a year and the total hours worked by employees was 1,000,000, the LTI rate would be 5.
