The accident triangle, also known as Heinrich's triangle or Bird's triangle, is a theory of industrial accident prevention. It shows a relationship between serious accidents, minor accidents and near misses.
Feb 20, 2024 · The Safety Pyramid, a time-tested framework developed in the 1930s by H.W. Heinrich, offers a strategic approach to reducing workplace accidents by focusing on the foundational elements of occupational health and safety.
Oct 29, 2019 · Herbert Heinrich, a pioneer in workplace health and safety, first proposed the relationship in 1931 by determining that if minor accidents are reduced then there will be a corresponding fall in the number of serious accidents.
Mar 21, 2024 · The safety pyramid, sometimes called the safety triangle, is a pictorial representation of a concept called Heinrich’s Law, developed by H. W. Heinrich. Heinrich, an employee of the Traveler’s Insurance Company in the 1930s, published a series of groundbreaking theories on health and safety at work.

Heinrich’s pyramid was first released in his book Industrial Accident Prevention: A Scientific Approach. Fundamentally, the pyramid claims that focusing on near misses and first aid incidents (bottom of the pyramid) leads to a reduction of fatalities and lost time injuries (top of the pyramid). Heinrich wrote that the root of 88% of incidents is ‘u...
To prevent serious harm, safety professionals must concentrate on the portion of near misses with SIF potential. Near misses with SIF potential are situations that could have caused major harm if conditions, systems, or acts were slightly different. For example, a back strain from manual handling has little SIF potential, while an elevated fall has...
Safety personnel require a systematic approach to record SIF potential and do something about it. In enterprises, this process is supported by powerful safety software, like Pro-Sapien.
In summary, it can be said that the Heinrich pyramid is accurate, but only at a very high level. Lots of near misses do not mean a fatality is imminent and solving lots of near misses does not mean a fatality is avoided. Safety managers must go deeper than the triangle, to unveil the portion of near misses with SIF potential. Then they must impleme...
