Which FOUR methods are typically used to extinguish fires with foam?

The correct answer identifies four key methods utilized to extinguish fires with foam: separating, smothering, penetrating, and cooling.

Separating involves creating a barrier between the fuel and the flames, which is particularly effective in preventing the spread of fire. Smothering occurs as the foam blankets the fire, displacing oxygen and thereby suffocating the flames. Penetrating refers to the foam's ability to infiltrate burning materials, aiding in extinguishment by addressing hidden pockets of fire. Cooling is essential as it reduces the temperature of the fuel and the fire, further assisting in its control and extinguishment.

These methods showcase how foam can effectively combat different aspects of a fire, mitigating its intensity and preventing re-ignition. By employing these strategies in combination, responders can efficiently manage and extinguish fires.
