What does "secondary containment" refer to in hazmat management?

Answer: C — system designed to contain leaks or spills from primary containers

"Secondary containment" refers to a system specifically designed to contain leaks or spills from primary containers holding hazardous materials. This is a crucial aspect of hazmat management as it serves as an additional layer of protection to prevent hazardous substances from escaping into the environment. The primary container is where the hazardous material is kept; however, if it were to leak or spill, secondary containment systems—such as berms, spill pallets, or double-walled tanks—act to catch that substance. This helps to mitigate environmental damage and ensures compliance with safety regulations. Understanding secondary containment is vital for ensuring that facilities that handle hazardous waste meet regulatory requirements and protect public health and safety.
