Safeopedia Explains Injury Severity Rate The frequency of injuries is an important safety metric, but without knowing how severe those injuries are, companies have an incomplete picture of their safety performance. The reason for calculating an accident frequency rate is to. Traditional severity metrics such OSHA DART Rate, Lost Work Days Case Rate and calculations based on lost and/or restricted days do not assess the severity exposure as well as SIF potential. An incidence rate of injuries and illnesses may be computed from the following formula: (Number of injuries and illnesses X 200,000) / Employee hours worked = Incidence rate. The fatal work injury rate was 3. The calculation is based on the number of mandatory reported OSHA recordable injuries and illnesses. A high TRIR rate can also mean an increase in your insurance rates. The formula for how to calculate TRIR is simple: the number of incidents, multiplied by 200,000, then divided by the total number of hours worked in a year. time equivalent (FTE) workers, which was the rate reported in 2018 and 2017. Calculate OSHA severity rate, DART rate, total case incident rate, and more here. If the injury does not cause loss of time in the period in which it occurs but in a subsequent period the injury should be included in the frequency rate of the period in which the loss of time begins. 2 makes a low TRIR rate. The LTIFR calculation is the same as the LTIR formula, but the 200,000 figure is replaced with 1,000,000 in this mathematical calculation.
