What should be ensured if using an interstice with vacuum during transportation?

When utilizing an interstice with vacuum during transportation, the primary consideration is that the interstice should be checked for leaks. This is crucial because a vacuum in the interstice helps in monitoring the integrity of the outer tank. If there is a leak, it can indicate a failure in the system that could lead to environmental contamination or product loss.

Ensuring that the interstice is leak-free allows for effective operation and monitoring. By maintaining a vacuum, any breach in the system would lead to a pressure change that can be detected early, preventing more significant issues down the line.

While reinforcement and keeping it empty may be good practices in some contexts, the focus on ensuring the integrity through leak checks is paramount for safety and regulatory compliance in underground storage tank systems. The choice about testing might suggest that no additional checks are needed, which overlooks the necessity of validating the vacuum system's effectiveness through leak detection.
