Which barrier stops the spread of petroleum products after the product has been removed?

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

Answer: (C)

Controlling oil on the water after the bulk product is removed relies on changing how the oil sits on the surface. Chemical barriers use agents that alter the surface-tension at the oil–water interface, causing the slick to contract and stay together rather than spreading out. This makes the remaining oil easier to contain and skim, since the residual sheen stays cohesive and within the containment boundary rather than fanning out. Floating booms are important for initial containment, but they rely on physical enclosure and can be less effective for thin or dispersed residues. Bubble barriers and the on-scene coordinator concept aren’t the standard method for stopping spread of the remaining product.
