What is the term for the placement of impervious materials to form a barrier to limit the spread of a liquid hazardous material?

The term for the placement of impervious materials to form a barrier to limit the spread of a liquid hazardous material is diking. Diking involves the use of physical barriers, often made from materials such as earth, plastic, or other impervious substances, to prevent the migration of hazardous liquids. This method is crucial in spill response efforts, as it helps to contain the material and minimize environmental impact as well as protect personnel from exposure.

Containment might appear similar to diking, but it refers more broadly to any measures taken to control the release and impact of hazardous materials, which can include diking, but also encompasses other methods like the use of booms or absorbents. Sealing usually pertains to methods used to close off openings to prevent leaks, while fortification refers more to strengthening structures or areas, which is less specific to the immediate containment of liquid hazardous materials. Understanding these distinctions is important for effective hazardous materials management and response strategies.
