This simple table is designed to assist you in making decisions around the hazards in your workplace.
It works simply by matching the likelihood of the injury (left hand column) with the potential consequence (right hand column) then
meeting on the area of risk.
Severity and Likelihood descriptions are found on page 2 and 3
Once you’ve ranked your risks, you MUST make a risk response plan to prevent or address those that are “high” or “extreme.”
You must ensure the risk rating is between moderate and very low and the controls in place before you begin.
You may not need to respond to risks ranked “low” or “medium” before work begins
