Configuring a risk matrix
The risk matrix is used to assess the potential damage of a hazard, based on the likelihood and severity factors. The likelihood and severity scores are multiplied to obtain a score value. This score is looked up in the risk ranges to determine the risk level. An example of a hazard risk matrix is given below:

Example, if Likelihood = Possible (3) and Severity = Major (4), the risk level is determined by severity * likelihood, which is 3*4 = 12. The score 12 falls in 'High' risk range.

The risk ranges are defined per hazard type. For more information, see Adding a risk range.
