How many yellow bands will be displayed on an 8-inch JP-8 pipeline?

The correct choice indicates that an 8-inch JP-8 pipeline will display three yellow bands. This is based on established military standards for marking fuel pipelines, which specify that the number of yellow bands is determined by the diameter of the pipe.

For an 8-inch pipeline, the identification standard states that yellow bands are placed at specific intervals to denote the type of fuel conveyed. These bands serve as important visual indicators for safety and operational awareness, clearly distinguishing the pipeline's function for personnel working in the vicinity.

In this context, the markings are crucial for preventing accidents and ensuring that personnel can easily identify JP-8 pipelines, which is a type of aviation fuel. Therefore, the presence of three yellow bands on an 8-inch pipeline is compliant with the marking guidelines, reinforcing the correct response.
