Damming is best described as

Damming is best described as

• A. Containment technique that is used when liquid is flowing in a natural channel or depression and its progress can be stopped by blocking the channel.
• B. The placement of materials to form a barrier that will keep a hazardous material in liquid form from entering an area, or that will hold the material in an area.
• C. Adding water to a solution to decrease the concentration
• D. Intended to redirect a liquids flow from an endangered area to an area where it will have less impact (usually storm drains)

Answer: (A)

Damming is a containment tactic that relies on blocking the flow path of a liquid in a natural channel or depression. By placing barriers across the route the liquid is taking, you create a temporary dam that stops or significantly slows its progress. This keeps the spill from rushing into new areas, buys time for assessment and cleanup, and helps you maintain control of the situation. It’s specifically about interrupting the flow in its current path, rather than simply surrounding the material with a barrier to keep it in place (a broader form of containment), diluting the liquid by adding water, or diverting the flow to a different area such as a storm drain.
