What is a common tactic used to confine a hazardous material?

Diking is a common tactic used to confine hazardous materials, particularly liquids, and it involves creating a physical barrier or embankment around the area where the hazardous material is located. This barrier helps to contain spills or leaks, preventing the contamination from spreading to surrounding areas. By constructing dikes or berms, responders can control the flow of hazardous substances and minimize their impact on the environment and human health.

Sealing typically refers to methods used to stop leaks in containers or tanks, but it does not specifically involve the creation of barriers to contain spillage. Blocking may involve stopping movement or access to an area but lacks the specific application of containing hazardous materials. Plugging often refers to methods used to fill holes or leaks in equipment or containers rather than creating a containment area. Each of these methods has its own application in hazardous material management, but diking is specifically aimed at confining free-flowing hazardous materials effectively.
