Lost time injury frequency rates. 0 or under as the average TRIR across the board was 3. during April. LTI is a Lost Time Injury (a work-related injury resulting in the loss of one or more complete workdays/shifts). The formula used to calculate the accident frequency rate is as follows: Accident Frequency = (Number of Accidents * 200,000) / Employee Hours Worked. The formula for calculating lost time injury frequency rate is the number of lost time injuries multiplied by 1,000,000, divided by the employee total. The number of reported accidents is derived from your operations, as is the total hours worked, while the number 200,000 is used in a number of safety KPI's to standardise the AFR.
