Yellow zone indicates what?

Yellow zone indicates what?

• A. Normal
• B. Over pressure
• C. Deficient
• D. Safe

Answer: (C)

Gauge color coding on ship systems uses green for normal operation, red for out of limits or danger, and yellow as a caution that the reading is deficient. A yellow zone means the parameter is below the required operating range and needs attention, but it isn’t yet in a critical red state. You should monitor and take corrective steps to bring it back into the normal range. That’s why deficient is the best description—the parameter isn’t adequate to meet the requirements, while normal, over pressure, and safe don’t match what yellow signals.
