Some of this criticism relates to the use of exact figures. A 2010 report about the oil and gas industry showed that the original values held true only when applied to a big dataset and a wide range of activities. A 1991 study suggested that in confined spaces the relationship was markedly different. There were 1.2 minor injuries for each serious injury or death . A broad study of UK accident data in the mid-1990s showed a relationship of one death to 207 major injuries, to 1,402 injuries causing three or more days lost time injuries, to 2,754 minor injuries. Unfortunately, Heinrich’s original record has since been lost. So it is impossible to prove his accident figures.
