Incident Impact Rates

Incident impact rates are based on the total impact of incidents (such as total cost or total number of days lost).

• Based on Total Number of Days Lost

  To compare rates across organizations the formula needs to scale up. Otherwise the rates can be so small that they are difficult to detect significant differences. This is done by multiplying the numerator (or impact of incidents) by the Frequency Rate Constant from the processing option. The formula is: (Number of Days Lost * the Frequency Rate Constant from the processing option/ Total Safety Metric).

• Based on Total Cost

  The impact rate of incident costs does not need to be scaled up since it is based on cost and not number of days lost. The formula is: (Total Incident Costs / Total Safety Metric).
