A physical condition indicating that the failure process has started corresponds to which failure type?

• A. Functional Failure
• B. Potential Failure
• C. Hidden Failure
• D. Occurrence Failure

Answer: (B)

A physical condition that shows the failure process has started is a precursor or early warning, called a potential failure. This means degradation is underway and could lead to a failure if nothing is done, but the system is not yet failing to perform its intended function. In maintenance practice, recognizing these precursor signals—like increasing vibration, rising temperatures, drifting readings, or emerging wear—allows proactive intervention before a functional failure occurs. Functional failure would mean the system actually stops meeting its required performance. Hidden failure is a fault that isn’t detectable by normal observation until a specific event reveals it. Occurrence failure refers to the actual event of a failure happening. The described condition best fits the idea of a potential failure, an early indicator that the fault process has begun.
