Description
Foam fire extinguishers are specialized for Class B fires and can be applied for Class A and Class K fires as well. They are most suited to extinguishing liquid fires such as petrol or diesel. The foam extinguishes liquid fires by sealing the surface of the liquid, preventing flammable vapor reaching the air and smother the fire. However, they are not suitable for use on free flowing liquid fires.
Always apply the P.A.S.S rule when using fire extinguishers.
- Pull out the safety pin
