Ensure trucks and trailers used for transporting aircraft potable water are clearly marked with what?

• A. Potable Water
• B. Non Potable Water
• C. Hazardous Material
• D. Untreated Water

Answer: (A)

Labeling for this scenario communicates safety and water quality to everyone handling the load. When trucks and trailers that carry aircraft potable water are clearly marked as Potable Water, it signals that the contents are treated and safe for human consumption and for filling aircraft water systems. This helps ground crews use the correct hoses, fittings, and handling procedures, and it prevents cross-contamination with non-potable or untreated fluids. The other options would mislead or create safety risks: Non Potable Water would indicate the water isn’t drinkable; Hazardous Material would imply dangerous goods; Untreated Water would suggest the water hasn’t been treated. So clearly marking Potable Water is the correct practice.
