Which term best describes a barrier created on a roadway, sidewalk, or floor?

• A. Levee
• B. Dike
• C. Barrier
• D. Barricade

Answer: (B)

In hazmat response, the key idea is to contain spilled liquids on a surface. A dike is a barrier specifically built to confine or hold back liquids, creating a controlled edge around a spill on roads, sidewalks, or floors. It acts like a temporary wall that prevents the material from spreading to other areas, making cleanup safer and more manageable. A levee is an earth or concrete embankment used to prevent flooding from rivers, not something you’d typically use to manage a spill on a roadway. A general barrier or barricade describes something that blocks access or channels traffic, but they don’t inherently contain liquid spills. So the term that best describes a containment barrier on a surface is the dike.
