Which technique requires being very close to the product?

• A. Vapor Dispersion
• B. Absorption with Sponge or Pad
• C. Vapor Suppression
• D. High Expansion Foam

Answer: (B)

Absorption with sponge or pad is the technique that requires getting very close to the product because its effectiveness depends on direct contact with the liquid. The sponge or pad must physically touch the spill to draw the liquid into its fibers or pores, soaking it up and lifting it away from the surface. This proximity allows rapid removal of the liquid and helps prevent spreading, especially for smaller spills or when you want to minimize vapors generated by surface exposure.

In contrast, vapor dispersion moves vapors away from the source through ventilation or air movement, so it’s done from a distance; vapor suppression uses a barrier or foam blanket to reduce vapor release without requiring contact with the liquid; and high expansion foam creates a surface covering to cool and isolate the spill, which also can be applied from a distance or across the area rather than touching the liquid directly.
