Heinrich’s1 Injury Triangle asserted that minor injuries predict serious injuries, and by controlling the causes behind minor injuries, serious injuries and fatalities (SIFs) will also be controlled.
This assertion has been questioned in recent years2,3,4,5 with data from numerous sources showing minor injuries nationwide decreasing, with a corresponding trend across all industries for SIF statistics to plateau. Recent work by Mercer ORC HSE Networks (now ORCHSE) showed about 20 percent of all the injury cases examined were potential SIFs.
