Water is one of your most effective fire extinguisher kinds. They should really only be used on Class A fires such as Paper, wood, fabrics, furnishings, and so on. Get a lot more information about огнетушитель цена
A water fire extinguisher is solid red in colour having a hose and nozzle attached, so it is possible to direct a stream of water at the bottom of the fire. As water conducts electricity, water fire extinguishers should not be used near exposed to live electricity cables. Water extinguishers are greatest kept alongside a CO2 extinguisher so the threat of electrical fires is covered inside your creating. Water extinguishers work by extinguishing the flames and soaking (cooling) the components inside 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 hazardous vapours under the surface of foam. Foam also penetrates porous materials and cools the fire because the water within the foam evaporates. Because 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 could be distinguished by their cream colour coded panel.
Carbon dioxide or Co2 fire extinguishers are safe to make use of on electrical fires. The Co2 gas is non-conductive and doesn't leave a residue behind that can effect the future functionality of electrical equipment in contrast to foam or powder extinguishers. These fire extinguisher forms are also helpful 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 can be 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 function. By far the most frequent extinguisher mix for efficient fire fighting is really a water or foam alongside a CO2 extinguisher.
Dry powder fire extinguishers would be the most flexible fire extinguisher kinds and are in a position to extinguish Flammable solids, liquids, gasses and electrical fires. They are usually recommended for use on vehicles and within the home, but though they may be multi goal, powder fire extinguishers are usually not recommended for use in enclosed spaces, or on sensitive electrical equipment if other far more appropriate varieties of extinguisher are obtainable. Powder fire extinguishers could be distinguished by their blue panel, and work by smothering the fire and stopping re-ignition
Wet chemical fire extinguishers have already 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, having said that regular fire extinguisher varieties for example these can aggravate a cooking fat fire as they cannot decrease the temperature of oil risking re-ignition, and may make hot oil splash up on contact with 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 physique and a extended lance used to safely distribute the extinguishing agent at a distance. This specialist fire extinguisher will not be intended for use on electrical equipment, but has passed the BSi 35kv conductivity test in case inadvertently used.
