The Selected Target can be set by clicking on the required Hazard ->SIL Determination -> Target Selection.
The Target Selection screen shows the results of the LOPA and/or the Risk Graph.
The Target can be selected from the assessed consequences or a Custom SIL or PFD / PFH:
- Safety (LOPA)
- Environmental (LOPA)
- Financial (LOPA)
- Reputation (LOPA)
- Safety (Risk Graph)
- Environmental (Risk Graph)
- Financial (Risk Graph)
- Reputation (Risk Graph)
- Custom PFD / PFH
- Custom SIL
For Custom PFD/PFH the SIL Target is determined from the entered PFD Target.
For Custom SIL Targets, the target PFD / PFH will be calculated as the geometric mean of the selected Target SIL.
Note – If the target is set based on a consequence assessment using the Risk Graph method then the Target PFD will be calculated as the geometric mean of the SIL Target.
A Hazard can be assigned a Status to mark its completeness. See our Status guide for more info.
