Water is one with the most efficient fire extinguisher forms. They must only be used on Class A fires such as Paper, wood, fabrics, furnishings, and so on.
A water fire extinguisher is solid red in colour with a hose and nozzle attached, so you may direct a stream of water in the bottom in the fire. As water conducts electricity, water fire extinguishers should not be used close to exposed to live electricity cables. Water extinguishers are finest kept alongside a CO2 extinguisher so the risk of electrical fires is covered in your creating. Water extinguishers work by extinguishing the flames and soaking (cooling) the materials in the fire.
As with water, AFFF foam functions on Class A fires but can also extinguish class B / flammable liquid fires. When sprayed onto a fire, AFFF foam extinguishes and smothers the flames, then seals in any risky vapours under the surface of foam. Foam also penetrates porous components and cools the fire 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 might be used near but not on live electrical equipment. Foam fire extinguishers is often distinguished by their cream colour coded panel.
Carbon dioxide or Co2 fire extinguishers are secure to utilize on electrical fires. The Co2 gas is non-conductive and does not leave a residue behind that should effect the future overall performance of electrical equipment as opposed to foam or powder extinguishers. These fire extinguisher sorts are also productive on Class B fires (flammable liquids). Carbon dioxide fire extinguishers are distinguished by a black panel around the extinguisher body and by their horn which is to become pointed in the fire but not held in case of a freeze burn. Some newer co2 fire extinguisher types have frost free horns as an added safety feature. One of the most frequent extinguisher mix for efficient fire fighting can be a water or foam alongside a CO2 extinguisher.
Dry powder fire extinguishers will be the most flexible fire extinguisher sorts and are able to extinguish Flammable solids, liquids, gasses and electrical fires. They are often suggested for use on cars and within the home, but while they are multi goal, powder fire extinguishers are usually not suggested for use in enclosed spaces, or on sensitive electrical equipment if other extra appropriate sorts of extinguisher are obtainable. Powder fire extinguishers might be distinguished by their blue panel, and work by smothering the fire and stopping re-ignition
Wet chemical fire extinguishers have already been created especially for extinguishing deep fat cooking fires. (Class F fires). Just before the creation of wet chemical extinguishers, most industrial kitchens had foam or powder extinguishers, having said that regular fire extinguisher sorts like these can aggravate a cooking fat fire as they can't reduced the temperature of oil risking re-ignition, and can make hot oil splash up on contact using the extinguishing agent.
When operated, a wet chemical extinguisher cools the flames and fat, and smothers the hot fat to stop re-ignition. A wet chemical fire extinguisher has a yellow panel on its body along with a long lance used to safely distribute the extinguishing agent at a distance. This specialist fire extinguisher isn't intended for use on electrical equipment, but has passed the BSi 35kv conductivity test in case inadvertently used.
