Before taking measurements during a bond test, a pipeline technician should first:

Before taking measurements during a bond test, it is essential for the technician to identify the bond locations at the structures. This step is crucial because it ensures the technician is aware of where electrical connections are made between the pipeline and other structures, such as cathodic protection systems or other pipelines. By pinpointing these bond locations, the technician can properly assess the effectiveness of the bonding and the integrity of the corrosion control measures in place.

Identifying bond locations allows for accurate and meaningful readings during the test, as measurements taken at the correct locations provide insight into potential issues with the bonding systems—such as inadequate connections or failures in the corrosion control system. This foundational understanding of the setup leads to better evaluation and troubleshooting of corrosion-related problems on the pipeline.

In contrast, other options involve steps that occur after bond locations are identified or do not provide the critical foundational understanding necessary to conduct an effective bond test. Prioritizing the identification of bond locations sets the stage for accurate testing and effective corrosion management within pipeline systems.
