The AFFF can quickly bring a fire under control. These foam solutions can be applied to a fire using either aspirating or non-aspirating devices. The Alcohol Resistant fire-fighting agent is particularly effective on fires of Class B materials including: alcohols, polar solvents, hydrocarbons and combinations such as gasohol.
A unique benefit for the foam-extinguishing agent is that it may be applied to a non-ignited Class B liquid spill to help seal the surface and prevent a serious fire from occurring. They are not suitable for use on free flowing liquid fires. Powder extinguishers are a good multi-purpose fire extinguisher because they can be used on Class A, B and C fires. They can also be used on fires involving electrical equipment however, they do not cool the fire so it can re-ignite.
Powder extinguishers can also create a loss of visibility and may create breathing problems. They are not generally recommended for use inside buildings unless there is absolutely no alternative. CO2 extinguishers are ideal for places with a lot of electrical equipment such as offices or server rooms because they are safe to use on fires involving electrical apparatus.
Carbon dioxide extinguishers do not leave any residue, unlike a foam extinguisher. They can also be used on Class B fires, those involving flammable liquids such paraffin or petrol. CO2 extinguishers work by smothering the fire and cutting off the supply of air.
Wet chemical extinguishers are suitable for use on Class F fires involving cooking oils and fats, such as lard, olive oil, sunflower oil, maize oil and butter. They are extremely effective, when used correctly. The wet chemical rapidly knocks the flames out, cools the burning oil and chemically reacts to form a soap-like solution, sealing the surface and preventing re-ignition. Although they are primarily designed for use on Class F fires, cooking oils and deep fat fryers.
They can also be used on Class A fires wood, paper and fabrics and Class B fires flammable liquids. Fire blankets are primarily for use on hot oil fires such as frying pans or small deep fat fryers. They can also be used on someone whose clothing has caught fire. They work by smothering the fire, stopping access to the oxygen fuelling it and extinguishing it. Therefore, this means they can be used on solid materials, flammable liquids and gases and electrical equipment.
Dangers: Do not use powder fire extinguishers on fires involving cooking oils or fats. How it works: The powder, which is released by a compressed gas, acts as an extinguishing agent to create an effective blanket over the flames, smothering its source and, as a result, cooling it and preventing it from spreading.
Dangers: Automatic fire extinguishers are not suitable for fires involving cooking oil or fat. How it works: Set off automatically, they usually protect a certain square footage by releasing an extinguishing agent. This makes them ideal for environments where manual operation is not always possible and where immediate activation is sometimes necessary, such as machinery and plant equipment, boat engine bays and flammable product storage areas.
Use: Wet chemical extinguishers have been specifically designed for fires involving cooking oils and fats Class F fires making them ideal for commercial and residential kitchens. Dangers: They are not suitable for, and should never used to tackle, fires involving flammable liquids or gases, metals or fires involving electrical equipment.
How it works: The wet chemical present is released as a fine spray which then dampens the flames. Simultaneously, the chemical element reacts with the fuel of the fire to create a film, sealing the surface and completely extinguishing it.
