Fluoroprotein foams are designed primarily for which type of fires?

Fluoroprotein foams are specifically formulated for fighting hydrocarbon fires, which primarily include flammable liquids such as gasoline, diesel, and oils. These foams work by forming a film over the burning liquid, effectively creating a barrier that suppresses the release of flammable vapors and prevents the re-ignition of the fire. The unique properties of fluoroprotein foams make them particularly effective against hydrocarbon fuels, as they can withstand high temperatures and provide efficient coverage over the liquid surface.

In contrast, other fire types such as metal fires, biological fires, and acid fires require different suppression methods and agents. For instance, metal fires often involve reactive metals like magnesium or sodium, which cannot be extinguished with water or foam. Biological fires would typically pertain to organic material combustion, while acid fires involve corrosive substances that need specialized agents for containment and suppression. Thus, the application of fluoroprotein foams is primarily relevant and advantageous in addressing hydrocarbon fires.
