What is Class A vs B vs C fire
Class A: solid materials such as wood or paper, fabric, and some plastics. Class B: liquids or gas such as alcohol, ether, gasoline, or grease. Class C: electrical failure from appliances, electronic equipment, and wiring. Class D: metallic substances such as sodium, titanium, zirconium, or magnesium.

What are the 4 classes of fire
Class A – fires involving solid materials such as wood, paper or textiles. Class B – fires involving flammable liquids such as petrol, diesel or oils. Class C – fires involving gases. Class D – fires involving metals.
What is a Type D fire
Class D fires involve combustible metals, such as magnesium, titanium, and sodium. Extinguishers with a D rating are designed to extinguish fires involving combustible metals.
What are Class A type 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.
Can you use an ABC extinguisher on a Class C fire
ABC extinguishers spray a fine chemical powder that smothers Class A and liquid fires, can break the chain reaction for liquid and gaseous fires, and is safe for Class C fires because it doesn't conduct electricity.
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.
What does a Class B fire include
Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.
What is B Type A fire
There are four classes of 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 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 fires are Class B
Class B. Class B fires involve flammable and combustible liquids such as gasoline, alcohol, oil-based paints, lacquers. Therefore, extinguishers with a B rating are designed to extinguish fires involving flammable and combustible liquids.
What types of fires are Class B
Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.
What not to use on a Class C fire
Class C: Electrical equipment, appliances and wiring in which the use or a nonconductive extinguishing agent prevents injury from electrical shock. Don't use water.
What fire Cannot be put out by ABC extinguisher
Class ABC fire extinguishers are designed to be used on all classes of fires except Class D fires.
What is a Class B fire extinguisher used for
Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.
What is a Type B fire extinguisher
Class B. Class B fires involve flammable and combustible liquids such as gasoline, alcohol, oil-based paints, lacquers. Therefore, extinguishers with a B rating are designed to extinguish fires involving flammable and combustible liquids.
What does a Class D fire involve
Class D fire extinguishers are commonly found in a chemical laboratory. They are for fires that involve combustible metals, such as magnesium, titanium, potassium and sodium.
What is a Class B fire
Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering. Class C: Electrical equipment, appliances and wiring in which the use or a nonconductive extinguishing agent prevents injury from electrical shock.
Can a Class C fire be put out with water
Keep in mind that Class C fires cannot be fought with water— using water as an extinguishing agent can actually make Class C fires worse! The most effective way to put out a Class C fire is to isolate the source of electricity and use a Class C fire extinguisher.
How do you put out a Class C fire
Since water is an electrical conductor, it can exacerbate the flames. To extinguish a class C fire, you should disconnect the appliance from its power source. Once disconnected, use a carbon dioxide or dry powder fire extinguisher.
What is involved in a Class 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 is an example of a Class 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 is an example of a Class E fire
Electrical fires are most common in commercial and residential settings. So, what is a class E fire It's an electrical equipment fire caused by a failure or malfunction within the electrical components of machinery or a piece of equipment. Electrical fires originate from electric wires, circuit breakers and cables.
What types of materials do Class B fires involve
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.
What type of fire is a Class A
Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics. The numerical rating on these types of extinguishers indicates the amount of water it holds and the amount of fire it can extinguish. The geometric symbol indicating Class A is a green triangle.
