Consider the consequences and likelihood for each of the identified hazards and use the table to obtain the risk level.
Consequences
1 – Insignificant
Dealt with by in-house first aid, etc
2 – Minor
Medical help needed. Treatment by medical professional/hospital outpatient, etc
3 – Moderate
Significant non-permanent injury.
Overnight hospitalisation (inpatient)
4 – Major
Extensive permanent injury
(eg loss of finger/s)
Extended hospitalisation
5 – Catastrophic
Death.
Permanent disabling injury
(eg blindness, loss of hand/s, quadriplegia)

How to Prioritise the Risk Rating
Once the level of risk has been determined the following table may be of use in determining when to act to institute the control measures.
Extreme
Act immediately to mitigate the risk.Either eliminate, substitute or implement engineering control measures.
Remove the hazard at the source. An identified extreme risk does not allow scope for the use of administrative controls or PPE , even in the short term.
High
Act immediately to mitigate the risk. Either eliminate, substitute or implement engineering control measures.
If these controls are not immediately accessible, set a timeframe for their implementation and establish interim risk reduction strategies for the period of the set timeframe.
