What does a secondary-containment system provide in relation to hazardous materials?

A secondary-containment system is designed to provide an additional layer of protection for hazardous materials stored in underground storage tanks. This system serves as a safeguard against leaks, spills, or overfilling, ensuring that any hazardous substances that escape from the primary containment are captured within the secondary system. This capability is crucial for preventing environmental contamination, protecting groundwater, and promoting safety in handling and storing hazardous materials.

The importance of this additional layer of protection cannot be overstated. It is a proactive measure intended to contain incidents before they can impact the environment or public health. This is particularly critical in industries that handle dangerous substances, where even small leaks can lead to significant environmental damage and regulatory consequences.

This understanding highlights the role of secondary containment systems as a critical component of safety practices in UST management.
