Fire extinguishers work by removing one or more components of the fire triangle. The fire triangle is the collective name for the three elements required to create and sustain a fire. These elements are heat, oxygen and fuel. The simplest elements to remove are heat and oxygen. For example a water jet fire extinguisher works by using the cooling effect of the water to remove the heat from the triangle, whereas a CO2 extinguisher removes the oxygen. A foam extinguisher aims to remove both, with the foam acting as a cooling agent but also a barrier to prevent further oxygen from reaching the fuel source.
