Which type of foam is specifically developed for polar solvents?

Alcohol-type protein foam is specifically designed for use with polar solvents, which can be challenging to suppress due to their unique chemical properties. These types of solvents, like acetone or ethanol, are water-miscible and do not mix well with traditional firefighting foams.

Alcohol-type protein foams contain additives that allow them to form a stable foam layer on the surface of polar solvents. This foam not only provides a barrier that prevents the release of flammable vapors but also has the ability to effectively suppress flames due to its cooling and smothering properties.

In contrast, standard protein foam and chemical foam are not formulated to combat polar solvents and may not be effective in those situations, which is why they are not suitable for these types of fires. Fluorine-based foams are typically designed for hydrocarbons, thus reinforcing the specificity of alcohol-type protein foam in tackling fires involving polar solvents effectively.
