Risk matrix form

Safety team can use the risk matrixes to create and conduct risk assessments in the Health and Safety Workspace.

For more information, see Conduct a safety risk assessment.

FieldDescription
Risk matrix details
NumberSystem-generated unique number for the risk matrix.
LocationLocation that this risk matrix applies to.
Short descriptionBrief description about the risk matrix.
Matrix gridSize of the grid to use, for example, 4\*4 and 5\*5.
ActiveOption for making the matrix available for use. A risk matrix must be active to be used.
Likelihood and severity
Likelihood levelDescription of the likelihood level. These descriptions are used to populate the likelihood options on risk assessments where this matrix is used. The number of likelihood levels is based on the selected grid size. For example, for a matrix grid of size 5\*2, there are five likelihood levels.
Severity levelDescription of the severity level. These descriptions are used to populate the severity options on risk assessments where this matrix is used.The number of severity levels is based on the selected grid size. For example, for a matrix grid of size 5\*2, there are two severity levels.
Risk tolerance
Risk tolerance

Range, color, and description of the risk level. Select a range and color and enter a title for it.This risk tolerance range and title computes the risk level for a hazard on the Hazard assessment form, Risk analyses tab, and the risk assessment form header. For more information, see Assess a hazard and its risk levels.

The value of the range is determined by multiplying likelihood level by severity level. For example, according to the grid in the following image, a hazard with a level 3 likelihood (Once per month) and a level 2 severity (Minor) has a risk tolerance of 3*2 = 6. The risk level for this hazard lies in the range 3 to 6, therefore, its risk level is displayed as Moderate.
