Foam Based

Foam-based fire extinguishers use aqueous film forming foam (AFFF), which is a type of synthetic surfactant.

When it comes to fire extinguishers, there are different types that are used for different types of fires. For example, foam-based fire extinguishers are typically used for Class A and B fires, which are common in commercial and industrial settings. Foam-based extinguishers work by creating a barrier between the fire and the oxygen that it needs to continue burning. This type of extinguisher is often used in areas where there is a lot of electrical equipment because it will not conduct electricity.
