Secondary containment refers to a backup system specifically designed to prevent hazardous waste spills from reaching the environment. This concept is crucial in hazardous waste management as it provides an additional layer of protection. The primary purpose is to contain any leaks or spills that might occur from primary containers, such as drums or tanks, thus ensuring that any hazardous materials stay within a controlled area and do not contaminate soil, groundwater, or surface water. This is particularly important in preventing environmental damage and protecting public health.

While other options involve aspects of hazardous waste management, such as recycling or neutralization, they do not define the concept of secondary containment effectively. Secondary containment is distinctly focused on spill prevention and environmental safeguarding, making it an essential practice in handling hazardous materials safely.
