How often must cathodic protection systems be inspected by a certified tester after installation?

Cathodic protection systems, which are critical for preventing corrosion on underground storage tanks and pipelines, must be inspected by a certified tester at regular intervals to ensure they are functioning properly. The requirement for these inspections typically aligns with regulatory standards to maintain safety and compliance.

Inspections every six months (the correct answer) are established to help detect any potential issues with the system early on, ensuring that it can effectively protect the metal surfaces from corrosion. This timeline allows for the ongoing evaluation of the system’s performance, helping to identify any necessary maintenance or repairs before corrosion can compromise the integrity of the tank or pipeline.

Other timeframes, such as annual or less frequent inspections, may increase the risk of undetected corrosion issues, leading to potential failures or environmental hazards. Regular semi-annual inspections play a critical role in the proactive maintenance of cathodic protection systems.
