Class B fires consist of all flammable liquids, including stove alcohol, grease, gasoline, diesel, kerosene, oil, oil based paint, teak oil, paint thinners, acetone, varnishes, and flammable gases or fumes. Class C fires consist of energized electrical equipment.

What are Class A and B fires?

Class A: Ordinary solid combustibles such as paper, wood, cloth and some plastics. Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.

What is a Class C fire?

Class C. Class C fires involve energized electrical equipment. Extinguishers with a C rating are designed for use with fires involving energized electrical equipment.

What are the 4 class fires?

What is a Class F fire?

Class F fires are fires which involve cooking oil or fat. Though technically a sub-class of fires caused by flammable liquids or gases, they differ from conventional fires due to the extremely high temperatures involved.

What is a Class E extinguisher?

Class E: Class E extinguishers stop electrical fires. This includes events related to electrical equipment that. requires electricity or circuit to operate. The class E extinguishers used for electrical-based fires include. Powder ABE and BE, carbon dioxide, and vaporizing liquid.

What is a Type D fire?

A Class D fire is characterised by the presence of burning metals. Only certain metals are flammable and examples of combustible metals include sodium, potassium, uranium, lithium, plutonium and calcium, with the most common Class D fires involve magnesium and titanium.

What are Class K fires?

What Are Class K Fires? A Class K fire is fueled by flammable cooking liquids, such as cooking oil, and animal or vegetable-based greases. These liquids, when brought up to high temperatures, become volatile and can easily ignite.

What extinguisher is Class C?

Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment. Both monoammonium phosphate and sodium bicarbonate are commonly used to fight this type of fire because of their nonconductive properties.

What type of fuel is a Class C fire?

A Class C fire is the burning of flammable gases.

These can include butane and propane, found in gas canisters used for camping stoves and gas barbecues.

What can cause Class C fire?

Class C fires may be started from faulty wiring, a short circuit, damage to power cords, overloaded electrical outlets, overheated or overcharged devices, etc. As long as the equipment is connected to its power source, the power acts as a continuous source of ignition.

What is Class C material?

What is a Class C or Class 3 fire rating? A Class C or Class 3 fire rating has a flame spread rating between 76 and 200. This rating incorporates building materials like plywood, fiberboard, and hardboard siding panels. It also includes any of the faster burning whole woods.

What do Class A fires contain?

Class A - fires involving solid materials such as wood, paper or textiles. Class B - fires involving flammable liquids such as petrol, diesel or oils.

What is an example of a Class A fire?

Wood, fabric, paper, trash ,and plastics are common sources of Class A fires. This is essentially the common accidental fire encountered across several different industries. Trash fires are one such example. Class A fires are commonly put out with water or monoammonium phosphate.

What is a Class B material?

In fire classes, a Class B fire is a fire in flammable liquids or flammable gases, petroleum greases, tars, oils, oil-based paints, solvents, lacquers, or alcohols. For example, propane, natural gas, gasoline and kerosene fires are types of Class B fires.

How do you fight a Class D fire?

To effectively fight a class D fire, you should use a dry powder fire extinguisher. Dry powder extinguishers will smother the oxygen from the fire, meaning it cannot maintain itself or grow any further.

What is in a class K extinguisher?

These extinguishers use a wet mist containing an alkaline mixture, like potassium carbonate, potassium acetate, or potassium citrate, which interact with the cooking media (oil, grease, or fat) to create a type of foam that blankets the oil or grease, cooling it and preventing it from being fed oxygen.

What type of fire extinguisher is Class K?

Class K fire extinguishers offer improved fire control for cooking fires by: Minimizing the splash hazard. Forming a soapy foam on the surface of the hot cooking oil, holding in the vapors and steam, and smothering the fire. (A process known as saponification.)

What does Class D fires represent?

A Class D fire involves flammable metals, such as magnesium, titanium, potassium, and lithium. It is important to note that not all metals are flammable. And even those which are, large sheets of the metal only pose a small risk. Instead, these fires are commonly the result of metal fines.

Where would you find a Class D fire?

They occur most often at laboratories, warehouses, and factories where they are used in manufacturing process to cut, drill or mill metals. Metal dust is created that is prone to creating fires. Sodium is very hazardous because it immediately burns when in contact with air or water causing explosions to occur.

Do Class B fires involve gases?

As alluded to above, Class B fires are ones in which flammable liquids and/or gases become involved. They are the fuel source in the fire triangle (fuel, heat, oxygen + chemical reaction). Flammable liquids include gasoline, diesel fuel, oils, tars, petroleum greases, solvents, alcohols, and oil-based paints.

What are the 4 types of fire extinguishers?

There are four classes of fire extinguishers – A, B, C and D – and each class can put out a different type of fire. Multipurpose extinguishers can be used on different types of fires and will be labeled with more than one class, like A-B, B-C or A-B-C.
