While all hazards are important, some are more likely than others, to result in harm or damage. Similarly, the amount or degree of harm or damage, varies with the hazard. The degree of a potential loss will dictate the required controls. Each time a hazard is identified and recorded, no matter what process or form is used, the hazard shall be risk classified.
The purpose for risk classifying hazards is to help prioritize the hazard for follow up action, and to help identify the degree / extent of action to be taken. Identifying the risk classification is dependent on three factors as follows:
Severity: |
If the hazard results in a loss, how severe is the loss likely to be. |
Probability |
What history do we have (what is the likelihood) that the hazard will result in a loss of the severity identified above. |
The following chart is to be used for determining the Risk Factor / Priority of a hazard:
Hazard Severity |
4 |
4 High |
8 High |
12 Very High |
16 Very High |
3 |
3 Medium |
6 High |
9 High |
12 Very High |
|
2 |
2 Low |
4 Medium |
6 High |
8 High |
|
1 |
1 Low |
2 Low |
3 Medium |
4 Medium |

The hazard Risk Factor / Priority is determined by multiplying the Hazard Severity X Probability = Risk Factor / Priority.
EG: A Severity of 3 and a Probability of 2 indicates a risk Factor of 6 (High) (3 X 2 = 6).
