Which term describes a barrier used to stop the spread of petroleum after removal, typically a chemical barrier?

• A. Floating Booms
• B. Bubble Barriers
• C. Chemical Barriers
• D. OSC

Answer: (C)

Chemical barriers are barriers formed by applying chemical agents to the oil on the water to change how the slick behaves, making it easier to contain. These products alter surface properties—often changing surface tension or viscosity—so the slick becomes more cohesive and easier to keep within a defined area or to recover. This is different from a physical barrier like a floating boom, which is a solid wall that oil cannot cross. In practice, chemical barriers are used to limit spread during cleanup, helping other containment or recovery methods work more effectively.
