Fires Categories
Fires can be grouped into four different categories. These are shown below:
Class Fires involve: Example Extinguish using: A combustible solids of an
organic nature wood or paper water, foam or dry powder B liquids and liquefiable
solids fat, wax, petrol or oil halon, foam, carbon dioxide, dry powder C gases
and liquefiable gases natural gas or LPG dry powder D metals or metal powders
sodium or magnesium powdered graphite, powdered talc, soda ash, limestone, dry
sandFires may be started by or involve electrical equipment but there is no
electrical fire classification. This is because it is the material that is
burning that denotes the classification, meaning that such fires must fall into
one of the above four categories. If a fire does involve electricity, the normal
procedure is to shut the power off and use a method of extinguishing appropriate
to what is burning. Special non-conductive agents such as powders and gases can
be used when the power supply can not be reached.
