Job Safety Analysis vs Risk Assessment

-

JSA and a (Qualitative) Risk Assessment (QRA) are different hazard and risk management tools. When you're doing a JSA, you are not, in fact, performing a risk assessment, which is a completely separate tool in risk management tool box.

In a JSA, the work team goes through a fairly simple analysis by breaking a job down into task-steps and then running through a six-step process to identify the following information: 1) the hazards in each step; 2) the triggers that could release the hazards; 3) the incidents that could occur in each step should the hazard be uncontrollably released; 4) the potential consequences of an uncontrolled hazard; 5) the prevention controls to be used to control the hazard; and 6) the mitigation and recovery controls to be used to manage any emergency and recover control over the hazard. I call the above process "Think 6, Look 6" to describe what workers need to do to complete a JSA!

In QRA, a team assesses the risk (likelihood) of any given incident (identified in step 3 above) occurring, that results in a given consequence (in step 4 above), and taking account of the controls being used (identified in steps 5 + 6). This assessment provides what we call the "residual" risk - the risk "left-over" once our controls are in place. The "raw" or inherent risk is assessed by simply not factoring in the use of controls.

  Reducing Error and Influencing Behaviour (HSG48) refers to Human Factors as,   “Human factors refer to environmental, organisational and job factors, and human and individual characteristics, which influence behaviour at work in a way which can affect health and safety.”   To simply understand the concept of influences of individual factors on human behaviour, different variables will be discussed with respect to their impact on people’s behaviour addressing health and safety. The Individual :  Individual factors are personal attitudes, skills, habits and personalities may be strengths or weaknesses depending on the job demands. These characteristics influence behaviour in complex and significant ways. Their effect may be positive or negative and may not always be mitigated by the job design. Some characteristics such as personality are largely – fixed and cannot be easily changed. Others, such as skills and attitudes, may more readily be changed or enhanced.
