Safeopedia explains Total Recordable Frequency (TRF)

Recordable incidents are those that result from an exposure or event in the workplace that either causes or contributes to:

  • Fatalities
  • Loss of consciousness
  • Lost work days
  • Restricted work activities
  • Job transfers
  • Medical care

Total recordable frequency rates of various types are used throughout industries for indications of past performance and not the future forecasts.

Calculating TRF

As per OSHA, calculation of TRF can be found by a simple equation:

TRF = 2000 x (number of recordable incidents) x 100 / (total man hours actually worked)

The 2,000 used to calculate TRF stands for the average amount of hours worked in a year by any given individual, based on the assumption that they will work 40 hours each week and work for 50 weeks.
