Emergencies – Risk Scale Examples


Emergencies – Risk Scale Examples


This is taken from the Victorian DET Guide to Developing an Emergency Management Plan  and provides descriptions of risk ratings to help complete the risk assessment template – refer Guide for further information


Consequence criteria

Descriptor Description
Insignificant Minor injury requiring no first aid or peer support for stress/trauma event.
Minor Injury/ill health requiring first aid. Peer support for stress/trauma event.
Moderate Injury/ill health requiring medical attention.  Stress/trauma event requiring professional support.
Major Injury/ill health requiring hospital admission.  Stress/trauma event requiring ongoing clinical support.
Severe Fatality or permanent disability.  Stress/trauma event requiring extensive clinical support for multiple individuals.

Likelihood scale

Note: The Likelihood scale refers to the likelihood of the risk event occurring

Descriptor Description Indicative %
Almost certain Expected to occur (>95%)
Likely Probably will occur (no surprise) (66 – 95%)
Possible May occur at some stage. (26 – 65%)
Unlikely Would be surprising if it occurred (5 – 25%)
Rare May never occur (<5%)


Insert the risk rating of either ‘Low’, ‘Medium’, ‘High’, or ‘Extreme’ in Column 4C along with the appropriate colour code as indicated in the Risk Rating Matrix below.

Risk rating matrix

Insignificant Minor Moderate Major Severe
Likelihood Almost Certain Medium High Extreme Extreme Extreme
Likely Medium Medium High Extreme Extreme
Possible Low Medium Medium High Extreme
Unlikely Low Low Medium Medium High
Rare Low Low Low Medium Medium

Risk evaluation

Risk evaluation involves comparing the current risk rating found during the analysis process with risk acceptance criteria established by the Department.

Is the level of risk acceptable?  Use the table below as a guide.  If the level of risk is not acceptable, you will need to identify additional treatments.

Risk acceptability chart

Extreme Unacceptable (must have Principal / School Council / Regional Office oversight
High Tolerable (with Principal Class Officer review)
Medium Tolerable (with frequent risk owner review)
Low Acceptable (with periodic review)
