Water is one of the most efficient fire extinguisher forms. They need to only be used on Class A fires which includes Paper, wood, fabrics, furniture, and so on. Get a lot more data about купить огнетушители киев
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 shouldn't be used near exposed to live electricity cables. Water extinguishers are finest kept alongside a CO2 extinguisher so the threat of electrical fires is covered in your building. Water extinguishers work by extinguishing the flames and soaking (cooling) the components in the fire.
As with water, AFFF foam functions 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 supplies 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 close to 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 protected to work with on electrical fires. The Co2 gas is non-conductive and doesn't leave a residue behind that will impact the future functionality of electrical equipment as opposed to foam or powder extinguishers. These fire extinguisher sorts are also powerful on 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 become pointed in the fire but not held in case of a freeze burn. Some newer co2 fire extinguisher varieties have frost free horns as an added safety function. Essentially the most frequent extinguisher mix for effective fire fighting is usually a water or foam alongside a CO2 extinguisher.
Dry powder fire extinguishers would be the most flexible fire extinguisher sorts and are capable to extinguish Flammable solids, liquids, gasses and electrical fires. They are generally advised for use on vehicles and inside the home, but even though they're multi purpose, powder fire extinguishers are usually not suggested for use in enclosed spaces, or on sensitive electrical equipment if other additional suitable sorts of extinguisher are out there. Powder fire extinguishers may be distinguished by their blue panel, and work by smothering the fire and preventing re-ignition
Wet chemical fire extinguishers happen to be made especially for extinguishing deep fat cooking fires. (Class F fires). Before the creation of wet chemical extinguishers, most industrial kitchens had foam or powder extinguishers, however typical fire extinguisher types which include these can aggravate a cooking fat fire as they can't reduce the temperature of oil risking re-ignition, and may make hot oil splash up on contact with all the extinguishing agent.
When operated, a wet chemical extinguisher cools the flames and fat, and smothers the hot fat to prevent re-ignition. A wet chemical fire extinguisher includes a yellow panel on its body in addition to a extended lance used to safely distribute the extinguishing agent at a distance. This specialist fire extinguisher is not intended for use on electrical equipment, but has passed the BSi 35kv conductivity test in case inadvertently used.
