California ICC UST Inspector Practice Exam

What is required if a tank fails the tightness test?

1. Immediate reuse of the tank

2. Repair or replacement by a factory authorized service

3. Notify the local agency only

4. Wait for a month before retesting

The correct answer is: Repair or replacement by a factory authorized service

When a tank fails a tightness test, it indicates there is a leak or potential failure in the containment system, which poses a risk to the environment and public safety. The appropriate action is to repair or replace the tank by a factory authorized service. This ensures that the repair or replacement meets the necessary safety standards and complies with regulatory requirements. Using qualified professionals ensures that the integrity of the tank is restored properly, minimizing the risk of future failures and potential contamination. Timely and proper action is crucial in such situations, as leaving a failed tank unrepaired could lead to environmental hazards and legal ramifications. Other responses such as immediate reuse, simply notifying a local agency without taking corrective action, or delaying action for a month all neglect the urgent need for safety and compliance following a failed test.
