Flammable liquids which fire extinguisher

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. An extinguisher with an ABC rating is suitable for use with fires involving ordinary combustibles, flammable liquids and energized electrical equipment.

An extinguisher that is rated for use with multiple hazards should include a symbol for each hazard type. Skip to main content. ABCs of Fire Extinguishers. Classifications of Fires and Extinguishers Class A Class A fires involve ordinary combustible materials, such as cloth, wood, paper, rubber, and many plastics.

Class B Class B fires involve flammable and combustible liquids such as gasoline, alcohol, oil-based paints, lacquers. Class C Class C fires involve energized electrical equipment. Class D Class D fires involve combustible metals, such as magnesium, titanium, and sodium. There are 6 types of fire, all classified and identified by the kind of materials found in the location in which the fire is present:. Class A — This type of fire is characterised by the presence of solids, including materials such as paper, wood and plastic.

Class B — Class B fires occur in environments where flammable liquids are found, such as paraffin, petrol and oil. Class C — Flammable gases are the main cause of Class C fires and include substances such as propane, butane and methane. Class D — This kind of fire is identified by the presence of metal products, such as aluminium, magnesium and titanium.

Class E — Class E fires are fires caused by electricity or ones that involve electrical equipment and apparatus. Class F — These fires most commonly occur in kitchens and food preparation facilities and involve cooking oil or fat. There are a variety of fire extinguisher types, all uniquely designed to combat various forms of fire:.

Use: Effective against both Class A and Class B fires, foam extinguishers can protect environments that are at risk from material fires, involving solids such as paper and wood, and also from fires involving flammable liquids. How it works: The foam is used to suffocate the fire and it seals the surface of the burning object or materials as it smothers it, cooling it down as it does so.

It also prevents stray materials scattering and starting fires elsewhere. Use: Water fire extinguishers are best for combatting Class A fires, for example fires involving organic solid materials, such as wood, cloth, fabric, paper and plastics.

Specialist dry powder extinguishers are only used on flammable metals, such as titanium and magnesium. Do not use for: — Fires involving cooking oil — Fires involving electrical equipment over v — or in enclosed spaces, such as offices or residential properties. How dry powder extinguishers work: Dry powder extinguishers smother fires by forming a barrier between the fuel and the source of oxygen. Where to locate Dry Powder extinguishers: — Place dry powder extinguishers near to the source of the fire risk.

They also put out Class B fires flammable liquids, such as paint and petroleum. Use for: — Flammable liquids, like paint and petrol — Electrical fires. Do not use for: — Kitchen fires — especially chip-pan fires — Combustible materials like paper, wood or textiles — Flammable metals. How CO2 extinguishers work: CO2 extinguishers suffocate fires by displacing the oxygen the fire needs to burn.

Overview: Wet chemical fire extinguishers are designed for use on Class F fires, involving cooking oils and fats. They can also be used on Class A fires although it is more common to have a foam or water extinguisher for this type of fire risk.
