When should you not use a foam fire extinguisher?
Foam Extinguisher (AFFF) Fires involving solids and burning liquids, such as paint and petrol but not suitable for chip or fat pan fires. Safe on fires caused by electricity if tested to 35kV (dielectric test) and a 1m safety distance is adhered to. Do not use on chip or fat pan fires.Click to see full…

Regarding this, what type of fire should you not use a foam extinguisher on? Foam Fire Extinguisher Use: Effective against both Class A and Class B fires, foam extinguishers can protect environments that are at risk from material fires, involving solids such as paper and wood, and also from fires involving flammable liquids. Dangers: Do not use on domestic chip or fat pan fires.Also, what type of fire should a foam extinguisher be used for? Foam extinguishers Foam fire extinguishers can be used on Class A and B fires. They are most suited to extinguishing liquid fires such as petrol or diesel and are more versatile than water jet extinguishers because they can also be used on solids such as wood and paper. Additionally, when would a foam type extinguisher be used? AFFF foam fire extinguishers are highly effective on class A and class B fires (the foam agent helps to prevent re-ignition). Some foam extinguishers have been dielectrically tested to 35000 Volt (35kV) and can be used on or near electrical appliances.What is a Class F fire?Class F fires are fires which involve cooking oil or fat. Though technically a sub-class of fires caused by flammable liquids or gases, they differ from conventional fires due to the extremely high temperatures involved.
