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 ...
local management aim to keep the plant open despite a desperate need for re-vamping and maintenance work; if the plant is closed down for a short period, if the problems are unattended, there is a risk that it may remain closed permanently.
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.
THERP analysis is very resource-intensive and may require a large amount of effort to produce reliable HEP values. This can be controlled by ensuring an accurate assessment of the level of work required in the analysis of each stage. [5] The technique does not lend itself to system improvement.
A hazard analysis may be used to inform decisions regarding the mitigation of risk. For instance, the probability of encountering an icy bridge may be reduced by adding salt such that the ice will melt. Or, risk mitigation strategies may target the occurrence.
Hazard analysis and risk-based preventive controls or HARPC is a successor to the Hazard analysis and critical control points (HACCP) food safety system, mandated in the United States by the FDA Food Safety Modernization Act (FSMA) of 2010.
Layers of protection analysis (LOPA) is a technique for evaluating the hazards, risks and layers of protection associated with a system, such as a chemical process plant. In terms of complexity and rigour LOPA lies between qualitative techniques such as hazard and operability studies (HAZOP) and quantitative techniques such as fault trees and ...
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 ...
