Water is one of those efficient fire extinguisher kinds. They should just be used on Class A fires such as Paper, wood, fabrics, furniture, etc. A water fire Extinguisher is strong red in color with a nozzle and hose attached, so it is possible to direct a flow of water in the base of the fire. As water runs electricity, water fire extinguishers should not be used near exposed to reside power wires. Water extinguishers are best maintained along with a CO2 extinguisher so the danger of electric fires is coated on your construction. Water extinguishers operate by extinguishing the fires and soaking (cooling) the substances from the fire.
Much like water, AFFF Foam operates on Class A fires but may also extinguish class B / flammable liquid fires. When sprayed on a fire, AFFF foam extinguishes and smothers the flames, then seals in almost any harmful vapours beneath the face of foam. Foam penetrates substances and also cools the fire because the water from the foam disappears. Since the foam extinguisher is non-conductive and analyzed to the BS EN3 35,000V dielectric evaluation, they might be used close but not on live electrical equipment. Foam fire extinguishers could be distinguished by their lotion color.
Carbon dioxide or Co2 fire extinguishers are safe to use on electrical fires. The Co2 gasoline is non-conductive and does not leave a residue behind this will impact the future operation of electric equipment unlike powder or foam extinguishers. These fire extinguisher forms can also be effective in Class B fires (flammable liquids). Carbon dioxide fire extinguishers are distinguished by a black panel on the extinguisher body and also from their horn that is to be pointed in the fire although not stored in the event of a freeze burn. Some newer co2 fire extinguisher forms have frost free horns as an extra security feature. The extinguisher mix for firefighting is foam or that a water along with a CO2 extinguisher.
Dry powder fire Extinguishers are the binh chua chay types and can extinguish Flammable fires. These are usually suggested to be used on vehicles and at the house, but although they are multi function, powder fire extinguishers are not suggested to be used in enclosed spaces or on sensitive electric equipment if other suitable kinds of extinguisher are readily available.
