Question

7 - What would green markings indicate about lines on One Call?

1 - Sewer Lines
2 - Drain Lines
3 - All clear to begin digging
4 - Both 1 and 2

Answer 1

Option 4. is correct. Green markings in the One Call color-coding system indicate the presence of both sewer and drain lines underground. The correct answer to the question is option 4, representing both sewer and drain lines.

Step-by-step explanation:

The question at hand pertains to the color-coding system used by One Call, which is a utility location service used to indicate the presence of underground utilities. In this color-coding system, green markings specifically highlight the presence of sewer lines and drain lines. Therefore, the correct answer to what green markings indicate about lines on One Call is option 4 - Both 1 and 2. This means that if you see green paint or flags when using the service, it denotes the location of sewer and drain lines underground, and not that it is all clear to begin digging.

Green markings on One Call indicate that the lines are either sewer lines (option 1), drain lines (option 2), or both (option 4). These markings serve as a way to communicate to construction workers and excavators that they need to exercise caution and avoid damaging these underground utilities during digging operations.
