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]
The risk management portion of the ARECC framework and process emphasizes leadership commitment to the safety and health mission and application of the hierarchy of controls. Commitment includes confirming that all ARECC process steps are being followed and that protection of safety, health, well-being, and productivity is being achieved.
Risk control logically follows after hazard identification and risk assessment. [3] The most effective method for controlling a risk is to eliminate the hazard, but this is not always reasonably practicable. There is a recognised hierarchy of hazard controls which is listed in a generally descending order of effectiveness and preference: [3]
Following the hierarchy is intended to lead to the implementation of inherently safer systems, ones where the risk of illness or injury has been substantially reduced. [ 8 ] Engineering controls are physical changes to the workplace that isolate workers from hazards by containing them in an enclosure, or removing contaminated air from the ...
ISO 31000 is a set of international standards for risk management.It was developed in November 2009 by International Organization for Standardization. [1] The goal of these standards is to provide a consistent vocabulary and methodology for assessing and managing risk, resolving the historic ambiguities and differences in the ways risk are described.
The risk rating of the hazard prior to applying the control is known as the 'inherent risk rating'. The risk rating of the hazard with the control in place is known as the 'residual' risk rating. Risk, within the occupational health and safety sphere, is defined as the 'effect of uncertainties on objectives [8] '. In the context of rating a ...
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.
Simple representation of exposure risk assessment and management hierarchy based on available information Hierarchy of occupational exposure limits (OELs) Illustration of statistical output from IHSTAT using air sampling data. Personal air sampling is routinely conducted on workers to determine whether exposures are acceptable or unacceptable.
