Which of the following is NOT a defensive spill control tactic?

• A. Neutralization
• B. Vapor suppression/dispersion
• C. Aggressive chemical mixing
• D. Damming

Answer: (C)

Aggressive chemical mixing is considered a tactical approach that could potentially lead to dangerous chemical reactions and is not typically classified as a defensive spill control tactic. Defensive spill control strategies are designed to contain and minimize the impact of hazardous materials spills without directly engaging with or altering the chemicals involved.

Neutralization aims to chemically react the hazardous material in a way that renders it less harmful, while vapor suppression or dispersion focuses on mitigating harmful vapors from escaping into the environment. Damming involves creating barriers to prevent the spread of a liquid spill. These tactics prioritize safety and containment, minimizing risks presented by the hazardous substances. In contrast, aggressive chemical mixing could result in unintended reactions that exacerbate the situation, leading to further hazards rather than controlling the spill.
