Classification of Fire
Fires have generally been classified as falling into one of four groups, a fifth has been added in recent years and if we include electrical fires it makes a sixth, although strictly speaking fires involving electricity fall into one or other of the 5 groups. The groups are know as the Classes of Fire and are designated A, B, C, D, F and if we include electrical class E.
Class A fires are fires involving organic solids such as paper, wood, textiles etc.
Class B fires are fires involving Flammable Liquids such as petrol, diesel, paints etc.
Class C fires are fires involving Flammable Gasses, such as Propane, Butane etc.
