Which color code represents sewage in the first piping color-code set?

• A. Gold
• B. Yellow
• C. Red
• D. Blue

Answer: (A)

Color coding helps you identify what’s inside a pipe at a glance, which is critical for safe operation and maintenance. In the first piping color-code set, the gold color is used to mark sewage lines. That means if you see gold on a pipe or label, it’s indicating wastewater, guiding you to handle it accordingly and avoid cross-connections or improper handling. The other colors in this set are assigned to different services, so they wouldn’t indicate sewage. Always check the specific color-code chart used on your vessel or facility, because schemes can vary between organizations. Recognizing that gold denotes sewage in this set helps you read layouts, plan isolation or repairs, and respond correctly in emergencies.
