RISK ASSESSMENT

RISK ASSESSMENT

Managing risks

Risk is the potential for injury or negative consequence based on the likelihood of a specific event occurring. Controls
must be put in place to eliminate the risk. Where the risk cannot be entirely eliminated, implement controls to reduce
risk by lowering the chance of the event occurring or minimising the severity of the consequence.
The risk matrix below can be used to provide a rank for any specific event.
