Safeopedia explains Total Recordable Frequencies (TRF)

As per OSHA, calculation of TRF can be found by a simple equation, TRF = 2000 (average hours worked in a year by an individual, 50 weeks and 40 hours per week) x number of recordable incidents x 100 / (divided by) total man hours actually worked. Recordable incidents are those which resulted from an exposure or event in the work place, death and injuries and illness that require medical treatment or first aid such as a cut, fracture, sprain, amputation, skin diseases, occupational asthma, pneumoconiosis, lead poisoning, solvent intoxication etc.. Any event or exposure in the work environment that either caused or contributed to the condition such as the workplace environment significantly aggravated an existing injury or illness are also included here.

TRF of various types are used throughout industries for indications of past performance and not the future forecasts. Incident rates have been standardized; therefore, OSHA and other government regulatory agencies can determine the need for safety program assistance. OSHA’s calculations enable the organization to report their recordable incident, lost time and severity rates, so that these are comparable. Smaller organizations that experience recordable incidents will most likely have high incident rates or fluctuation from year to year. Calculations are more significant at larger companies that have a larger work force.
