The correct term is "Secondary Containment," which refers to an additional layer of protection used to capture and contain spills from hazardous materials, preventing them from leaking into the environment or causing harm. This is typically in the form of a secondary pan, basin, or other equipment that surrounds primary containers or tanks used for storing hazardous substances.

The concept of secondary containment is vital in laboratory settings and industries that handle hazardous materials, as it minimizes the risk of contamination and protects personnel and the environment from potential chemical spills. This safety measure is also a regulatory requirement in many cases, ensuring compliance with environmental protection standards.

Other terms like "Secondary Liquid," "Primary Defense," or "Containment Vessel" do not accurately describe the additional protective equipment designed specifically for spill containment. While a containment vessel may hold hazardous materials, it does not inherently refer to the secondary measure for capturing spills, and primary defense typically relates to other safety protocols rather than spill containment.
