Fire Extinguisher Types

Water is one with the most efficient fire extinguisher forms. They ought to only be used on Class A fires such as Paper, wood, fabrics, furniture, etc. Get additional data about купить огнетушители киев



A water fire extinguisher is strong red in colour having a hose and nozzle attached, so you can direct a stream of water in the bottom with the fire. As water conducts electricity, water fire extinguishers shouldn't be used near exposed to live electricity cables. Water extinguishers are most effective kept alongside a CO2 extinguisher so the danger of electrical fires is covered within your building. Water extinguishers work by extinguishing the flames and soaking (cooling) the materials within the fire.



As with water, AFFF foam performs on Class A fires but also can extinguish class B / flammable liquid fires. When sprayed onto a fire, AFFF foam extinguishes and smothers the flames, then seals in any dangerous vapours under the surface of foam. Foam also penetrates porous materials and cools the fire as the water inside the foam evaporates. As the foam extinguisher is non-conductive and tested towards the BS EN3 35,000V dielectric test, they might be used near but not on live electrical equipment. Foam fire extinguishers might be distinguished by their cream colour coded panel.



Carbon dioxide or Co2 fire extinguishers are protected to use on electrical fires. The Co2 gas is non-conductive and does not leave a residue behind which will impact the future efficiency of electrical equipment unlike foam or powder extinguishers. These fire extinguisher types are also effective on Class B fires (flammable liquids). Carbon dioxide fire extinguishers are distinguished by a black panel around the extinguisher physique and by their horn that is to be pointed at 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 function. One of the most frequent extinguisher mix for effective fire fighting is really a water or foam alongside a CO2 extinguisher.



Dry powder fire extinguishers would be the most flexible fire extinguisher sorts and are able to extinguish Flammable solids, liquids, gasses and electrical fires. These are typically suggested for use on autos and inside the home, but though they're multi purpose, powder fire extinguishers aren't suggested for use in enclosed spaces, or on sensitive electrical equipment if other much more appropriate kinds of extinguisher are out there. Powder fire extinguishers is usually distinguished by their blue panel, and work by smothering the fire and preventing re-ignition



Wet chemical fire extinguishers have been designed particularly for extinguishing deep fat cooking fires. (Class F fires). Before the creation of wet chemical extinguishers, most industrial kitchens had foam or powder extinguishers, on the other hand typical fire extinguisher kinds 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 includes a yellow panel on its physique plus a extended lance used to safely distribute the extinguishing agent at a distance. This specialist fire extinguisher is just not intended for use on electrical equipment, but has passed the BSi 35kv conductivity test in case inadvertently used.
