The term referring to the placement of impervious materials to create a barrier that restricts the spread of liquid hazardous materials is diking. Diking involves constructing physical barriers, such as earth mounds or synthetic containment devices, around the hazardous material. These barriers are designed to contain spills, preventing the movement of contaminants into the environment, thereby reducing the risk of environmental damage and ensuring safety during hazardous material incidents.

In hazardous materials management, diking is a critical practice that protects water sources and sensitive ecological areas from potential contamination by confining any spills to a designated area, allowing for more manageable clean-up processes. The effectiveness of diking in controlling hazardous materials highlights its importance in emergency response and environmental protection strategies.

Other terms like containment, while related, refer to broader strategies that can include diking as a method among others. Neutralization involves chemical processes to make substances less harmful, and segregation refers to keeping hazardous materials apart from one another to prevent reactions or accidents, which is a different approach from forming barriers specifically aimed at containing spills.
