Perform a Preliminary Hazard Analysis

When performing a Risk Analysis (also known as Preliminary Hazard Analysis), five different document object types are involved. The central document object is the Risk Analysis that describes the hazardous situation. It links to Harms and optionally Measures in the system and keeps these links as a Probability Of Harm object. As input to the Risk Analysis, zero or more Causes may be defined.

Causes, Measures and Harms can only be created directly from the Project Explorer.

Measures and Harms can be assigned to the Risk Analysis by clicking on Add Row. To remove an assigned object, please use the applicable Remove Row button. Causes can only be assigned by setting traces outside of the editor. A Cause should trace towards a Risk Analysis object.

To create a Risk Analysis as above, please follow these steps:

  • Create a Harm, Measure and Cause (in any order)

  • Create a Risk Analysis object

  • Assign the Harm to the Risk Analysis. Here Aligned Elements automatically creates a ProbabilityOfHarm object.

  • Set the probability for the row.

  • Assign the Measure to the Risk Analysis.

After the Risk Analysis object has been saved, you may assign any Cause to the Risk Analysis by selecting Trace From... in the Actions drop-down and select one or more causes.

Measures may be edited directly in the Risk Analysis form whereas Harms and Causes can only be edited when opened from the Project Explorer.
