A barrier created on a roadway, sidewalk, or floor is best described as a

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

Answer: (B)

Spill containment on a surface uses a dike. A dike is a raised or bermed barrier placed around a spill to keep the liquid from spreading across the floor, sidewalk, or roadway. Levees and dams are large-scale structures for holding back river water, not for small spills on pavements. A barricade blocks access but doesn’t confine liquid. So for a barrier created on a roadway, sidewalk, or floor to contain a liquid, the term that fits best is dike.
