Which two colors denote equipment areas at the gate?

The correct choice indicating the colors that denote equipment areas at the gate is white and red. These colors are significant as they are universally recognized safety indicators within airport environments.

In aviation and airport settings, white typically signifies a safe area for parking and maneuvering machinery and equipment, while red often indicates caution or a warning area. The combination of these colors helps personnel easily identify where equipment should be located and the necessary precautions to take when working in these areas. Utilizing these colors effectively enhances safety by ensuring that drivers and operators are aware of the specific zones intended for equipment usage.

Other color combinations like black and white or white and blue serve different purposes and might not directly relate to equipment areas, emphasizing the importance of adhering to standardized color codes for clarity and safety in airside operations.
