Which type of foam is effective on polar solvents?

Alcohol-resistant foam is specifically formulated to combat fires involving polar solvents, which include substances like acetone, ethanol, and other alcohol-based fuels. These types of chemicals are particularly challenging for traditional foam agents because they can break down many foams by mixing with the water content, which diminishes the foam's effectiveness.

Alcohol-resistant foam has unique additives that aid in maintaining its integrity and effectiveness when in contact with polar solvents. This type of foam forms a barrier that helps suppress the release of flammable vapors, cooling the surface and reducing the risk of re-ignition.

Ultimately, by using alcohol-resistant foam, firefighters can effectively manage and extinguish fires involving polar solvents, ensuring a safer response to such hazardous situations.
