Hierarchy of hazard controls

Hazard control methods at the top of the graphic are potentially more effective and protective than those at the bottom. Following this hierarchy of controls normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced.[1]

Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards.[a] It is a widely accepted system promoted by numerous safety organizations. This concept is taught to managers in industry, to be promoted as standard practice in the workplace. It has also been used to inform public policy, in fields such as road safety.[13] Various illustrations are used to depict this system, most commonly a triangle.

The hazard controls in the hierarchy are, in order of decreasing priority:

The system is not based on evidence about effectiveness but based on If elimination of the hazard is possible, it frees workers of being aware of the hazard and protecting themselves. Substitution has less priority than elimination because the substitute can possibly also come with a hazard. Engineering controls depend on a well-functioning system and human behaviour. Administrative controls and personal protective equipment are always dependent on human behaviour which makes these controls less reliable.
