Which method is used for containment when dealing with a liquid hazardous material spill?

• A. Diking
• B. Neutralization
• C. Solidification
• D. Vapor dispersion

Answer: (A)

Diking is a method used for containment during a liquid hazardous material spill. It involves creating barriers, typically using earthen materials or specially designed barriers, to confine the spilled liquid and prevent it from spreading further into the environment. This method is effective in controlling the flow of the hazardous substance and minimizes the risk of environmental contamination or exposure to individuals in the vicinity.

While other methods like neutralization and solidification address hazardous materials in different ways, they do not primarily focus on containment. Neutralization involves chemically transforming a hazardous material into a less harmful substance, while solidification refers to converting a liquid hazardous material into a solid state for easier handling or disposal. Vapor dispersion, on the other hand, is a technique typically used for handling gaseous releases rather than liquid spills. Therefore, diking stands out as the most appropriate method for containing liquid spills specifically.
