Which of the following tactics would be used for diverting a hazardous substance?

• A. Vapor dispersion
• B. Blocking
• C. Damming
• D. Liquid containment

Answer: (C)

Damming is a tactic used to control and divert the flow of hazardous substances, particularly liquids. It involves creating a physical barrier or obstruction, such as earth or other materials, to contain or redirect the hazardous material away from sensitive areas or toward a designated containment area. This method is particularly useful in incidents involving spills, where the goal is to prevent the hazardous substance from spreading further and to facilitate cleanup efforts.

In situations involving hazardous materials, appropriate tactics must be chosen based on the properties of the substance, the environment, and the potential risks to public health and the environment. Damming provides a structural solution to manage hazardous liquids, making it a crucial tactic in hazardous material response scenarios.
