USCG Exam PracticeHand/power tools, measuring instruments, and maintenance
During an engineering watch, a watchstander notices a temperature reading that is slowly drifting above its normal band. According to proper watchstanding practice, what is the correct immediate action?
- A. Record the reading in the log and wait for the alarm to activate before taking further action
- ✓ Investigate and report the out-of-band reading without waiting for an alarmCorrect
- C. Reduce engine speed to bring the temperature back into the normal band
- D. Notify the OCMI before taking any corrective action
Why B is correct
Trends matter more than single readings. A temperature slowly drifting off normal is an early warning of fouling, wear, or a developing failure. Any reading outside its normal band is investigated and reported, not simply written down, and a good watchstander catches it before an alarm does.
