What does the term "secondary containment" refer to?

• A. An emergency response protocol
• B. An additional containment system designed to catch leaks or spills from primary containers
• C. A method of securing hazardous waste
• D. A type of personal protective equipment

Answer: (B)

The term "secondary containment" specifically refers to an additional containment system that is designed to capture any leaks or spills that may occur from primary containers. This concept is crucial in hazardous materials management because it provides an extra layer of security to prevent hazardous substances from escaping into the environment.

The design of secondary containment systems typically includes facilities like spill berms, containment trays, or double-walled tanks. By utilizing secondary containment, operators can effectively mitigate the risk of environmental contamination and protect human health by ensuring that any hazardous materials released from primary storage are contained and can be managed appropriately.

Other options address different aspects of hazardous materials management but do not define secondary containment. For instance, emergency response protocols relate to actions taken during an incident, securing hazardous waste involves storage and handling but does not necessarily imply containment, and personal protective equipment pertains to safety gear for individuals working with hazardous materials rather than containment structures. Thus, secondary containment plays a vital role in environmental protection and compliance with safety regulations.
