Which type of tanks have interstitial sensors?

  1. Single wall tanks

  2. Double wall tanks

  3. Both single and double wall tanks

  4. Neither type of tanks

The correct answer is: Double wall tanks

Double wall tanks are designed with an extra layer, or wall, that serves as an additional barrier to prevent leaks. The space between the two walls is known as the interstice, and it is where interstitial sensors are placed. These sensors are used to monitor for leaks of the stored liquid, as any liquid that breaches the inner wall would collect in the interstitial space, triggering the sensors. The use of interstitial sensors is crucial for environmental protection and safety, as they help to detect leaks before they escape into the surrounding area. This design feature enhances the overall integrity of double wall tanks, making them suitable for the storage of hazardous materials and complying with regulatory requirements regarding spill prevention. In contrast, single wall tanks lack this additional physical barrier and therefore do not utilize interstitial sensors, as they do not provide the same level of spill containment or monitoring capability. This distinction emphasizes the importance of double wall tanks in regulated environments, particularly in preventing environmental contamination from leaking products.
