What should be done if an indication of leakage through a crack is discovered on an in-service tank?

• A. A soft patch should be applied over the crack and the area observed for 24 hours
• B. It may be possible to caulk the crack to stop the leakage
• C. The tank shall immediately be removed from service, drained, opened, and repaired
• D. The tank should be removed from service as soon as possible and a complete inspection with subsequent repairs made

Answer: (D)

When a leakage indication through a crack is discovered on an in-service tank, the most appropriate action is to remove the tank from service as soon as possible and conduct a complete inspection followed by necessary repairs. This approach prioritizes safety and environmental protection by preventing further leakage that could lead to significant issues such as contamination or structural failure. Immediate removal from service allows for a thorough investigation of the tank's condition, which is crucial to assess the extent of the damage and determine the right repair strategy. The complete inspection can uncover other potential issues that may not be visible but could compromise the tank's integrity. In contrast, applying a soft patch or caulking the crack may provide a temporary solution but does not address the underlying problem. These methods could risk worsening the situation or lead to more serious leaks if the tank is not properly inspected and repaired. Ensuring a comprehensive evaluation and repair process is essential to maintain safety standards and compliance with regulatory requirements.
