Which of the following is a defensive spill control tactic?

• A. Incineration
• B. Absorption
• C. Ignition
• D. Evaporation

Answer: (B)

Absorption is recognized as a defensive spill control tactic because it involves the use of materials that can soak up liquid pollutants, effectively reducing the amount of hazardous material that can spread and minimize environmental impact. By using absorbent materials, responders can contain the spill to a specific area, making it easier to manage and remove without allowing further contamination.

In contrast, incineration, ignition, and evaporation are more aggressive tactics that do not prioritize containment of the hazardous material. Incineration involves burning hazardous substances, which may create other risks and emissions. Ignition can refer to using flame or heat to manage spills but fails to contain the material effectively. Evaporation entails allowing the hazardous liquid to vaporize, which can lead to airborne pollutants and doesn't prevent further dispersion. Thus, absorption stands out as a method focused on controlling and limiting the spread of hazards.
