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.
Hierarchy of controls. Hierarchy of control is a system used in industry to minimize or eliminate exposure to hazards. [7] It is a widely accepted system promoted by numerous safety organizations. This concept is taught to managers in industry, to be promoted as a standard practice in the workplace. [7]
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]
The anticipate, recognize, evaluate, control, and confirm (ARECC) decision-making framework began as recognize, evaluate, and control.In 1994 then-president of the American Industrial Hygiene Association (AIHA) Harry Ettinger added the anticipate step to formally convey the duty and opportunity of the worker protection community to proactively apply its growing body of knowledge and experience ...
Hazard elimination is a hazard control strategy based on completely removing a material or process causing a hazard.Elimination is the most effective of the five members of the hierarchy of hazard controls in protecting workers, and where possible should be implemented before all other control methods.
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 ...
Administrative controls are fourth in larger hierarchy of hazard controls, which ranks the effectiveness and efficiency of hazard controls. [2] Administrative controls are more effective than PPE because they involve some manner of prior planning and avoidance, whereas PPE serves only as a final barrier between the hazard and worker.
Where a guide word is meaningfully applicable to a parameter (e.g., "no flow", "more temperature"), their combination should be recorded as a credible potential deviation from the design intent that requires review. The following table gives an overview of commonly used guideword-parameter pairs (deviations) and common interpretations of them.
