Adding a Safety State Transition Step
Each safety state transition step performs a single action, such as issuing or releasing a safety document. To add safety state transition steps, do the following:
1. From a switching, create a new safety document. See “Creating a Safety Document from a Switching Sheet” for more information.
2. Validate that step recording is still turned on in the Steps tab.
3. Click the Issue button () on the safety document. A new safety state transition step is recorded into the switching sheet steps list. The Operation column of the step indicates the type of operation being performed.
Notes:
Conditions associated to the assets in the Tag Points list has to be on the assets for the document to be issued. If the conditions are not on the assets, an error dialog box will be displayed with the list of conditions that could not be found. The switching steps associated to those conditions will be highlighted in the switching sheet. This is mode specific, so when in study mode, the conditions have to be on the assets in your study session. Conditions are not required when only the Other Assets field is filled out.
When recording the safety state transition steps in Real-Time, the safety document must have an assigned crew before it can be issued. This is not a requirement when in Study mode.
4. Select the Release and Complete buttons on the safety document. New safety state transition steps are recorded into the Steps list for the Release and Complete operations.
5. Close the safety document.
Note: If you changed the Other Assets or Description field, you will be asked to save the changes. All other fields are automatically saved within the associated switching steps.
For instructions on executing safety state transition steps, see “Executing Safety State Transition Steps”.
Safety State Transition Failed Dialog Box
When a safety document is issued the conditions (tags) associated with it are locked. If some of the expected conditions are missing or fail to lock, the Safety Transition Failed dialog box is displayed. The Failed Safety Actions table contains the list of switching steps associated with the safety document, that caused the failure.
The switching steps placing those conditions will be highlighted on the Steps tab. Affected rows in the Tag Points list in the safety document will also be highlighted.
