Which concentrate is designed for fires involving water-soluble materials and halocarbons?

• A. Alcohol-resistant foam concentrate
• B. Aqueous film-forming foam concentrate (AFFF)
• C. Film-forming fluoroprotein foam concentrate (FFFP)
• D. Protein foam concentrate

Answer: (A)

Alcohol-resistant foam concentrates are formulated to withstand the presence of water-soluble fuels (like alcohols) and halogenated solvents, preserving the foam blanket and the protective film even when polar solvents are present. This makes them the best choice for fires involving water-soluble materials and halocarbons, where standard foams would break down or wash away. AFFF is optimized for hydrocarbons and can be less effective with polar solvents, while protein and film-forming fluoroprotein foams don’t provide the same level of resistance to polar solvents or halocarbons.
