True or False: Air tests are effective without soaping and inspecting for bubbles?

Air tests for Underground Storage Tanks (USTs) are critical to ensuring the integrity of the tank and identifying potential leaks. The process involves pressurizing the tank with air and then monitoring for pressure drops. However, simply conducting the air test without the supplementary step of soaping and inspecting for bubbles is ineffective.

When a soap solution is applied to the suspected areas of the tank, it creates bubbles in the presence of escaping air. This visual inspection is essential because it allows for precise identification of leak points. Bubbles indicate that air is escaping, confirming a leak, which helps in taking corrective actions promptly. Without this inspection, a pressure drop might occur without clear identification of the source, leading to unresolved issues and potential environmental hazards.

In summary, a thorough evaluation of a tank's integrity requires not just the air test but also the crucial step of soaping and inspecting for bubbles. This ensures proper detection of leaks, safeguarding against possible contamination and regulatory violations.
