Incident Frequency Rates

Incident frequency rates are based on the total number of incidents per safety metric (typically hours). To compare rates across organizations the formula needs to scale up. Otherwise the rates can be so small that it is difficult to detect significant differences. This is done by multiplying the numerator (or count of incidents) by the Frequency Rate Constant from the processing option. The formula for incident frequency rates is (Count of Incidents * the Frequency Rate Constant from the processing option/ Total Safety Metric). This is a standard industry calculation.
