CONSEQUENCES

Risk Management - Sample 5 x 5 Risk Assessment Matrix

Likelihood Severity (consequences)

Severity (consequences)

5. Almost Certain

5. Fatality

4. Probable

4. Major Injury, resulting in disability

3. Possible

3. Injury Requires, Doctor's or Hospital attendance

2. Possible (under unfortunate circumstances)

2. Minor Injury, 1st Aid required

1. Rare

1. Minor Injury, 1st Aid not required

Risk Rating is calculated by multiplying the likelihood against the consequences, e.g. taking a likelihood of 4, which is classified as Probable, and multiplying this against a consequence of 2, which is classified as a Minor Injury 1st aid required, would give you and overall risk rating of 8, which would be risk rated as a low risk.


High risk equals 16 to 25.

High Risks activities should cease immediately until further control measures to mitigate the risk are introduced.


Medium risk equals 9 to 15.

Medium Risks should only be tolerated for the short-term and then only whilst further control measures to mitigate the risk are being planned and introduced, within a defined time period.  


Note: Medium risks can be an organisations greatest risk, it's Achilles heel, this due to the fact that they can be tolerated in the short-term.


Low risk equals 1 to 8.

Low Risks are largely acceptable, subject to reviews periodically, or after significant change etc...
