Alcohol resistant foam is used for liquids such as

• A. Water
• B. Acids
• C. Ethanol and Other Alcohol-Based Liquids
• D. Dense Emulsions

Answer: (C)

Alcohol-resistant foam is designed for liquids that contain alcohols, because alcohols can break down the surface film of ordinary foams and cause the foam blanket to collapse. The special AR foam forms a durable surface film and maintains a stable foam blanket even when the fuel is alcohol-based, allowing cooling and containment of the fire. That’s why it’s the best fit for ethanol and other alcohol-based liquids. Water alone isn’t flammable, and while acids or dense emulsions have their own handling needs, they don’t demand the alcohol-resistance feature that AR foams provide.
