Which standard note addresses Loss of System?

• A. Standard Note 1
• B. Standard Note 2
• C. Standard Note 3
• D. Standard Note 4

Answer: (B)

Loss of System is handled by a predefined, step-by-step response crafted to be quick and repeatable, so operators know exactly what to do when a system stops functioning. The second standard note is the one that specifies the actions for this contingency, making it the best match. It provides the appropriate sequence: recognize the failure, isolate or shut down the affected portion to prevent further issues, switch to backup controls or alternate pathways if available, reconfigure to keep critical functions going, and notify the watch team as part of a controlled, documented response. The other notes cover different fault conditions or partial failures and thus don’t provide the correct procedures for a complete Loss of System, which is why this one is the correct choice.
