“Create an event tree for a pipeline leak with leak detection, remote isolation, and ignition prevention barriers, ending in contained release, jet fire, large release, or uncontrolled release.”
פענחו את ההחלטות שמאחוריו.
Alarm response must occur before remote isolation can be effective.
Closing the line limits release size.
Preserve an ignition branch only while material is still released.
Use for a high-level leak-response review before performing detailed dispersion or consequence modelling.
שאלות נפוצות
What is the initiating event here?
The initiating event is a pipeline leak, expressed with a frequency before any barrier succeeds or fails.
Why is isolation after detection?
Detection identifies the event and triggers the response that allows remote isolation to close the line.
Can I add more barriers?
Yes. Add barriers such as emergency response, deluge or evacuation in the order they influence the scenario.
