Question 795 Deck Safety

The correct answer is A) Alcohol. Regular foam is not an effective extinguishing agent for alcohol-based fires. Alcohol-based fires require a special type of foam called alcohol-resistant foam to be effectively extinguished. Crude petroleum, jet fuel, and motor gasoline are all hydrocarbon-based flammable liquids that can be extinguished using regular foam. The reason alcohol-based fires require a specialized foam is that alcohol is miscible with water, meaning it can mix with water. Regular foam is water-based, so it is not able to create a stable barrier between the fuel source (alcohol) and the fire. Alcohol-resistant foam, on the other hand, is designed to create a stable barrier that can effectively extinguish alcohol-based fires.
