Incidence Rate: A measure of the frequency with which a disease occurs in a population over a specified time period. Using this TRIFR calculation formula, the result is the total recordable injury frequency rate. The calculation of the SIIR uses the same hours worked number as your calculation of the Recordable Incidence Rate. This is the current recommended formula by the New Zealand BusinessLTISR means lost time incident severity rate = (days lost because of lost time injuries) x 1,000,000 / worked hours)In 2020, the TRIR at the Caylloma Mine was 5.
