Which of the following foam types is specifically designed to resist alcohols?

The type of foam specifically designed to resist alcohols is alcohol-resistant foam. This foam formulation incorporates additives that enhance its ability to maintain stability and effectiveness in the presence of polar solvents, such as alcohols. Unlike other foam types, which may be effective against hydrocarbons but not specifically resistant to alcohol-based fuels, alcohol-resistant foam forms a protective layer that prevents alcohol-based products from breaking down the foam's structure. This characteristic makes it particularly useful for fighting fires involving alcohols and other polar solvents, ensuring that the foam remains effective even when in contact with these types of flammable liquids.
