Assuming 20% of the hazards account for 80% of the injuries, and by categorizing hazards, safety professionals can target those 20% of the hazards that cause 80% of the injuries or accidents.

Alternatively, if hazards are addressed in random order, a safety professional is more likely to fix one of the 80% of hazards that account only for some fraction of the remaining 20% of injuries.

The idea has a rule of thumb application in many places, but it is commonly misused.

For example, it is a misuse to state a solution to a problem "fits the 80/20 rule" just because it fits 80% of the cases; it must also be that the solution requires only 20% of the resources that would be needed to solve all cases.

Additionally, it is a misuse of the 80/20 rule to interpret a small number of categories or observations.

This is a special case of the wider phenomenon of Pareto distributions.Conversely, the hardest 20% of the code takes 80% of the time.
