What is a 'warning' in the CSOSS alarm hierarchy?

• A. A non-critical indicator alerting to potential issues that require monitoring or planned action, not immediate risk.
• B. A fatal system shutdown indicator.
• C. A redundant message with no meaning.
• D. A mandatory action that must be executed immediately.

Answer: (A)

A warning in the CSOSS alarm hierarchy is a non-critical indicator that signals a potential issue requiring monitoring or planned action, but not immediate risk. It alerts operators to keep an eye on the condition and prepare for a response, allowing the system to continue operating while corrective steps are planned or implemented. This distinguishes it from a fatal shutdown indicator, which would require urgent protective action; from a message with no meaning, which provides no useful information; and from an immediate-action directive, which demands prompt, urgent steps at once.
