How does the use of double-walled tanks benefit hazardous materials storage?

The use of double-walled tanks is primarily designed to enhance the safety and integrity of hazardous materials storage. These tanks consist of two walls, with an outer wall that serves as a protective barrier. This design effectively helps prevent leaks and contain spills that could occur from the inner tank.

In the event of a failure or breach in the inner tank, the outer tank acts as an additional safeguard by containing the hazardous materials, thereby minimizing the risk of environmental contamination and protecting public health. This containment system not only prevents materials from escaping into the surrounding environment but also aids in compliance with regulatory standards regarding hazardous materials storage.

While other options might touch upon relevant aspects of storage, they do not encapsulate the primary function and benefit of double-walled tanks as effectively as the prevention of leaks and containment of spills.
