secondary containment

Secondary containment refers to a safety system designed to prevent environmental contamination from leaks or spills of hazardous substances, such as chemicals or fuels. It involves creating an additional barrier around a primary storage container, like a tank or drum, to catch any leaks that may occur. This could be in the form of a secondary tank, a berm, or a containment pad. The main purpose is to protect soil and water resources from pollution, ensuring that accidental spills have minimal impact on the environment. It's an important practice in industries handling potentially harmful materials.
