Water is certainly one of the very most fire that is efficient types. They should only be properly used on Class A fires Paper that is including, fabrics, furniture, etc.

A water fire extinguisher is solid red in color with a hose and nozzle attached, so you can direct a stream of water in the bottom of the fire. As water conducts electricity, water fire extinguishers really should not  be used near subjected  to live electricity cables. Water extinguishers are well held alongside a CO2 extinguisher so  the risk of electrical fires is covered in your building. Water extinguishers work by extinguishing the flames and soaking (cooling) the materials in the fire.

Much like water, AFFF foam works on Class A fires but can additionally extinguish class B / flammable liquid fires. When sprayed onto a fire, AFFF foam extinguishes and smothers the flames, then seals in any vapours that are dangerous the surface of foam. Foam also penetrates materials that are porous cools the fire as the water into  the foam evaporates. Due to the fact foam extinguisher is non-conductive and tested towards the BS EN3 35,000V dielectric test, they could  be utilized near but not on live equipment that is electrical. Foam fire extinguishers could be distinguished by their cream colour coded panel.

Carbon dioxide or Co2 fire extinguishers are safe to use on electric fires. The Co2 gas is non-conductive and doesn’t leave a residue behind that may effect the future performance of electrical gear 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 panel that is black the extinguisher body and by their horn which is become pointed during  the fire but  not held in the event of a freeze burn. Some newer co2 fire extinguisher types have frost free horns as an added safety feature. Probably the  most extinguisher that is frequent for efficient fire fighting is a water or foam alongside a CO2 extinguisher.

Dry powder fire extinguishers are the most fire that is flexible types and are in a position  to extinguish Flammable solids, fluids, gasses and electrical fires. These  are often recommended  for use on vehicles and  in your home, but although they are multi purpose, powder fire extinguishers are not advised for use in enclosed spaces, or on sensitive electric equipment if other more suitable types of extinguisher are available. Powder fire extinguishers can be distinguished by their blue panel, and work by smothering the fire and re-ignition that is preventing

Wet chemical fire extinguishers happen designed especially for extinguishing deep cooking that is fat. (Class F fires). Ahead of  the creation of damp chemical extinguishers, many commercial kitchens had foam or powder extinguishers, however normal fire extinguisher types such as these can aggravate a cooking fat fire because  they cannot lower the heat of oil risking re-ignition, and can make hot oil splash up on contact utilizing  the extinguishing representative.

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 has a yellow panel on its human body and a long lance used to safely distribute the extinguishing agent well away. This expert fire extinguisher isn’t meant to be used on electrical equipment, but has passed the BSi 35kv conductivity test in case unintentionally utilized.
