Use interim controls: If more time is needed to implement long-term solutions, the hierarchy of controls should be used from the top down as interim controls in the meantime. Avoid introducing new hazards: Keep in mind is that the selected controls should never directly or indirectly introduce new hazards.
English: “The idea behind this hierarchy is that the control methods at the top of [the] graphic are potentially more effective and protective than those at the bottom. Following this hierarchy normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced” [1]
Figure 3 illustrates how the pyramid formulation of the interrelated elements of the hierarchy of control can be used to provide retrospective, contemporaneous, or prospective insights about the sustainability and levels of risks associated with work activities that involve different combinations of hazards, exposures, controls, and resulting ...
The Hierarchy of Controls Applied to NIOSH Total Worker Health is a conceptual model for prioritizing efforts to advance the safety, health, and well-being of all workers. This model applies the framework of Total Worker Health approaches to the traditional Hierarchy of Controls used in occupational safety and health. Like the traditional ...
Engineering controls is the third of five members of the hierarchy of hazard controls, which orders control strategies by their feasibility and effectiveness. Engineering controls are preferred over administrative controls and personal protective equipment (PPE) because they are designed to remove the hazard at the source, before it comes in ...
NIOSH considers PtD to be "the most effective and reliable type" of prevention of occupational injuries. [12] A core tenet of PtD philosophy is the concept of addressing workplace hazards using methods at the top of the hierarchy of hazard controls, namely elimination and substitution.

Substitution is the second most effective of the five members of the hierarchy of hazard controls in protecting workers, after elimination. [ 1 ] [ 2 ] [ 3 ] Substitution and elimination are most effective early in the design process, when they may be inexpensive and simple to implement, while for an existing process they may require major ...
