What type of fire is suitable for foamite extinguishers?

Foamite extinguishers are particularly effective for controlling fires involving flammable liquids, which fall under Class B fires. These types of fires include substances like gasoline, oil, and paints. The foam created by these extinguishers effectively smothers the flames and prevents the release of flammable vapors, making them ideal for such scenarios.

Class A fires, on the other hand, typically involve solid combustibles like wood, paper, and textiles. While foam can suppress these flames, it is not as effective as water, which is the primary extinguishing agent recommended for Class A fires. Class C fires involve electrical equipment, for which foam extinguishers are not suitable due to the risk of electric shock. Class AB is not a standard classification for fire types and may cause confusion in identifying the appropriate extinguishing agents.

In summary, foamite extinguishers are best suited for Class B fires, making them an essential tool for situations involving flammable liquids.
