What does "Secondary Containment" refer to?

Secondary containment refers to a robust system designed to prevent the release of hazardous materials into the environment in the event that the primary containment fails. This typically involves the use of an additional barrier, such as a dike or a containment basin, that surrounds tanks or containers used to store hazardous substances. The primary goal is to capture any leaks or spills that might occur, thereby protecting soil and groundwater from contamination.

The concept is critical for regulatory compliance and environmental safety, ensuring that even if the primary defense against leaks fails, hazardous materials are still contained and managed to minimize environmental impact. The other options, while related to safety and management of hazardous materials, do not accurately describe the technical term of secondary containment.
