A client for whom we had implemented a predictive safety analytics dashboard came to us with an interesting research proposition. They had seen a constant decline in reportable incidents in recent years, but no improvement in first aid cases.
This is inconsistent with a nearly century-old theory known as the Heinrich/Byrd Safety Pyramid, commonly referred to as the “Safety Triangle”. It proposes that the ratios between fatalities, accidents, injuries, and minor incidents follow a fixed pattern (the ratios represented in progressive stages of a pyramid).
Our client wanted to understand why this commonly employed theory was not holding true.
