Most commonly used on Class B fires (flammable liquids), a foam fire extinguisher is also a recommended choice for Class A risk areas (those featuring combustible materials). These extinguishers perform a cooling function and quickly smother burning materials, while the foam agent helps prevent the fire reigniting.

Foam fire extinguishers shouldn’t be used on kitchen fires or those with an electrical source. However, they’re ideal for office environments, hospitals, schools and other spaces where organic materials play a large role in the landscape. Browse high-performance foam extinguishers in a range of finishes.
