Why must you always know where a cleaning tool is in the sewer?

• A. So the tool can find its way back
• B. So you can locate it when resuming work after an interruption
• C. So you know obstructions or difficulties are encountered
• D. None of the above

Answer: (C)

Knowing where the cleaning tool is in the sewer lets you detect problems in the line as you work. If you can track its position, you’ll notice when it encounters an obstruction or other difficulty, so you can stop, back out, or adjust before causing damage or losing control of the tool. This awareness directly supports safe operation and protects equipment and pipes. The other ideas aren’t the primary reason: tools aren’t reliable at finding their own way back, and while tracking can help resume work after an interruption, the main purpose is to recognize obstructions or difficulties as they happen.
