USCG Exam PracticeHand/power tools, measuring instruments, and maintenance
According to 46 CFR §61.40-10, when a test of a monitored system would damage equipment or endanger personnel, which alternative technique is acceptable?
- A. Bypassing the sensor entirely and manually entering the expected alarm setpoint into the log
- ✓ Using a synthesized signal or condition applied to the sensor, provided the test equipment is maintained in good working order and periodically calibrated to the satisfaction of the OCMICorrect
- C. Mis-adjusting the system temporarily to simulate the alarm condition, then restoring normal settings
- D. Revising the system wiring to produce the desired signal, provided the revision is documented and reversed within 24 hours
Why B is correct
46 CFR §61.40-10(b) prohibits simulating monitored system conditions by mis-adjustment, artificial signals, improper wiring, tampering, or revision of the system, but expressly permits a synthesized signal applied to the sensor when the test would damage equipment or endanger personnel, subject to calibration requirements acceptable to the OCMI.
