What type of system provides an additional layer of protection against product release?

A secondary-containment system is specifically designed to offer an additional layer of protection against the release of hazardous materials, such as fuel or chemicals, into the environment. This system consists of a structure or containment area that surrounds the primary containment—such as a tank or piping.

In the event of a leak or failure in the primary containment, the secondary containment system acts as a safeguard, preventing the hazardous material from escaping into the soil, groundwater, or surrounding areas. This is particularly important in applications like underground storage tanks (USTs), where any release can significantly impact the environment and public health.

By implementing a secondary-containment system, facilities can enhance their safety measures, comply with regulatory requirements, and minimize the risk of environmental contamination, making it an essential aspect of modern installations and retrofitting practices.
