If extensive internal or external piping corrosion is found prior to measuring structure to soil potentials, a pipeline technician should ________.

Documenting the condition and notifying personnel responsible for correcting the problem is crucial when extensive internal or external piping corrosion is identified. This approach ensures that the situation is acknowledged and addressed appropriately, as corrosion can compromise the integrity of the pipeline and pose safety risks. By documenting the findings, you create a record that can be used for analysis and future reference, allowing for a systematic evaluation of the corrosion issue.

Notifying responsible personnel ensures that corrective actions, such as repairs or further assessments, can be initiated. This proactive communication is essential in maintenance practices, as it helps prioritize safety and operational efficiency, which may be at risk due to the identified corrosion.

Other options may either overlook the severity of the corrosion or risk further complications by trying to address the measurements without rectifying the underlying issue first. Prioritizing documentation and communication helps maintain safety and compliance standards in pipeline management.
