fire Extinguisher Types
Water is one of the most efficient flame extinguisher types. They should by yourself be used on Class A fires including Paper, wood, fabrics, furniture, etc.
A water flare extinguisher is sound red in colour in imitation of a hose and nozzle attached, for that reason you can take in hand a stream of water at the bottom of the fire. As water conducts electricity, water blaze extinguishers shouldn't be used close exposed to live electricity cables. Water extinguishers are best kept contiguously a CO2 extinguisher correspondingly the risk of electrical fires is covered in your building. Water extinguishers take steps by extinguishing the flames and soaking (cooling) the materials in the fire.
As afterward water, AFFF foam works on Class A fires but can after that overwhelm class B / flammable liquid fires. gone sprayed onto a fire, AFFF foam extinguishes and smothers the flames, then seals in any dangerous vapours under the surface of foam. Foam in addition to penetrates porous materials and cools the blaze as the water in the foam evaporates. As the foam extinguisher is non-conductive and tested to the BS EN3 35,000V dielectric test, they may be used close but not on breathing electrical equipment. Foam flare extinguishers can be distinguished by their cream colour coded panel.

Carbon dioxide or Co2 flare extinguishers are secure to use on electrical fires. The Co2 gas is non-conductive and does not leave a residue in back that will effect the well ahead show of electrical equipment unlike foam or powder extinguishers. These ember extinguisher types are plus committed upon Class B fires (flammable liquids). Carbon dioxide fire extinguishers are distinguished by a black panel on the extinguisher body and by their horn which is to be critical at the ember but not held in encounter of a deaden burn. Some newer co2 ember extinguisher types have frost clear horns as an extra safety feature. The most frequent extinguisher mixture for efficient ember accomplishment is a water or foam next door to a CO2 extinguisher.
Dry powder flare extinguishers are the most flexible flame extinguisher types and are practiced to exterminate Flammable solids, liquids, gasses and electrical fires. These are often recommended for use on vehicles and in the home, but although they are multi purpose, powder ember extinguishers are not recommended for use in enclosed spaces, or upon pining electrical equipment if supplementary more pleasing types of extinguisher are available. Powder ember extinguishers can be distinguished by their blue panel, and proceed by smothering the ember and preventing re-ignition
Wet chemical flame extinguishers have been intended specifically for extinguishing deep fat cooking fires. (Class F fires). since the creation of damp chemical extinguishers, most industrial kitchens had foam or powder extinguishers, however normal flame extinguisher types such as these can upset a cooking fat ember as they cannot humiliate the temperature of oil risking re-ignition, and can create hot oil splash taking place on entrance considering the extinguishing agent.
When operated, a wet chemical extinguisher cools the flames and fat, and smothers the warm fat to prevent re-ignition. A damp chemical blaze extinguisher has a yellowish-brown panel upon its body and a long lance used to safely distribute the extinguishing agent at a distance. This specialist fire extinguisher is not meant for use on electrical equipment, but has passed the BSi 35kv conductivity test in accomplishment by coincidence used.
With every blaze extinguisher types, it is important to ensure that all potential flare extinguisher users are trained on how to fake them safely and know which types of fire an extinguisher can and cannot be safely used on.
